The development of knowledge and advancement in technology has created a wide-ranging transformation in societies and has led to changes in the per-formance of companies in order to respond to environmental turmoil and social expectations. In this way, they tried to gain a significant competitive advantage over other competitors. The purpose of this study was to investi-gate the moderating role of managerial fortification in relation to the impact of technology-based capabilities on the product market competition of knowledge-based companies in the capital market: a source-based capabili-ties (DEA). This research is applied in terms of purpose and in terms of data envelopment analysis is a quasi-experimental and post-event research in the field of positive accounting research. Then, based on multivariate regression, the research hypothesis was tested using Eviews software. The statistical population studied in this study consisted of knowledge-based companies listed on the Tehran Stock Exchange during the years 2015 to 2019 and 79 companies were selected and reviewed based on systematic screening. The result of testing the research hypothesis is that the technological capabilities have a positive and significant effect on the product market competition of knowledge-based companies in the capital market. This result demonstrates that the resource-based technology capability based on the source-based capabilities is seen as a resource against stagnation in a competitive environ-ment and helps the company, to maintain flexibility in the face of environ-mental change in order to respond faster, at the same time to develop the company's competitive capacity to create new resources or new and innova-tive products, and to make the company's future more attractive to stake-holders with greater returns and potential risk control.

1 Introduction
The basic concept of governance is defined in a wide range, as a network of relationships that includes not only a company and its owners, but also all stakeholders including employees, customers, people, society, etc [1]. The most important element of this system are managers, whose decisions can be influential in a wide range and for which they must be accounTable to a wide range of stakeholders [2]. But in unsTable and complex environmental conditions; increasing competition; with the increasing development of communications and technological advances, company managers are facing new conditions in terms of competition, and what determines the success of firms in the survival and advancement of their goals, these are the strategies that they should choose based on their decision-making approaches based on the turbulent environment [3]. These strategies today are different from the past, more than anything else, depending on the level of technology-based capabilities, because the growth and development of technologies has caused drastic changes in the competitive processes of companies. As the environment and market space changes due to the multiplicity of competitors and the intensity of competition, companies also have to use technology-based capabilities based on resource-based view to grow and achieve their goals [4]. The resource-based view is one of the foundations of technological capabilities in the field of knowledge-based companies, which has greatly helped to maintain the superiority of companies over competitors. Because the resource-based view, due to the internal characteristics of companies in a competitive market, evaluates the level of capabilities and capacities that can be developed in various dimensions such as technology core and provides the possibility of sustainable development for companies [5]. In other words, this approach considers the reason for the different competitive power of companies operating in this field, in their unique resources and assets, assets that, while practical, must be innovative and based on competitive values. It is noteworthy that these unique assets and resources are not necessarily purchasable and need to be created based on strategic mechanisms based on technological costs [6]. For example, although technological development is an asset based on capital and cash resources, the value and level of knowledge that is generated from it is based on learning approaches at the competitive level of capital market companies [7]. In other words, this approach has features such as valuable, rare, imitability and in-substituTable for resources [8]. In fact, according to the resource-based view (RBV), companies always try to strengthen various infrastructures such as technological development by focusing on technological capabilities such as research and development, so that information feedback is more dynamically reflected to stakeholders to increase the effectiveness of the company's interaction with stakeholders. This form of capital market interaction will be possible through the disclosure of transparent financial reporting to shareholders and investors [9, 10]. Technology-based capabilities also help knowledge-based companies to be more successful in product market competition. Carayannis & Sagi [11] using case studies of successful companies, identify key components of product competitiveness in capital market-active industries at three national levels; Industry and companies were identified. They examine the interrelationships between product market competitiveness based on productivity (profitability) and innovation and developed their observations and conclusions by creating the CPI model which is the basis for gaining a competitive advantage, while creating a dynamic interaction between the government; Industry and companies are the development of technology-centric competitive capabilities. On the other hand, Li et al [12] by examining the level of technological capabilities stated, lack of technology-based capabilities can reduce the quality of information and information asymmetry due to the company's inability to compete with other companies with a competitive advantage, because the lack of these capabilities is considered a kind of non-response to market changes and shareholders, realizing this, may lose confidence in the company's competitiveness for greater returns, and the company faces the risk of a financial crisis under these circumstances. Fang [11] also cited the existence of technology-based capabilities based on the dynamics of competitive capabilities as a reason for companies to differ in profitability and gain a competitive advantage in the product market. They described the existence of these capabilities as a factor in information transparency as a basis for competitiveness in the product market. In fact, technology-based capabilities are a set of capabilities; Skills and infrastructure knowledge in knowledge-based companies to gain a competitive advantage in the product market which help companies in choosing the most appropriate technologies to maximize productivity to reduce their costs and create a favorable environment for sustainable development [13]. According to the descriptions given, this study seeks to investigate the moderating role of managerial entrenchment on the impact of technology-based capabilities on the product market competition of knowledge-based companies in the capital market based on data envelopment analysis (DEA) to create a technical efficiency of a company compared to competitors in the field of turning research and development resources into an innovative product.
2 Literature Review
2.1 Technological Capabilities
Technological capability, or IT, is the ability to control IT-related costs, deliver systems on time, and influence business goals through IT implementation [14]. This capability has been studied from several perspectives; How it relates to work design, process change, power relations and collaboration [15] and a number of studies have examined it from a resource-based perspective [16, 17]. From the point of view of a resource-based approach to diversification, valuable, scarce, inimiTable and irreplaceable resources create a competitive advantage. Therefore, information technology should be considered as an organizational capability that leads to competitive advantage by leading the company to superior performance [18]. In addition, Madhavaram and Hunt [19] based on resource advantage theory, organizational resources in a hierarchy of basic resources (such as information resources, relationships and human resources), combined (eg, A + B = C) and interconnected (for example, a × b) are categorized, because organizational capabilities and / or competencies are formed through a bowl of basic resources [20]. It can be said that IT capability is a source of mixed factor. Mixed sources can be measured through their constituent components, which can be tangible or intangible [19]. Therefore, IT capability can have different dimensions depending on the number of separate IT-based resources. IT capabilities can be divided into 4 sections and several components: [21].

2.2 Resource-Based View in the Development of Technological Capabilities
The resource-based view is a competitive performance model that focuses on resources and capabilities controlled by the firm as a source of competitive advantage, one of the dimensions of which is technology-based capability. Empirical evidence consistently states that industry structure or external factors cannot be the sole determinants of competitive strategy and competitive performance [22]. For this reason, a group of theorists in this field such as Maiti et al [23]; Andersen [24] and Fahy [25] stated that having the distinct gifts of strategic resources is the ultimate determinant of strategy and performance. This attitude is exactly in line with the phenomenon of knowledge-based competition. Such competition causes the long-term success of a company to depend on what it knows and understands, and therefore competitors look at capabilities and competencies as the key to success against their competitors [26]. Resource-based view was introduced by Barney [27], and the key to success is focusing on intangible assets such as knowledge. In fact, these resources can act as barriers to copying and imitating other assets, so they are imiTable, irreplaceable, valuable, and scarce. Other capabilities include team knowledge, organizational culture, organizational history, learning, management skills and the like. Technological capabilities help the company to achieve a competitive advantage and create more value for stakeholders than other competitors in the competitive market. In fact, competitive advantage includes a set of technological factors or capabilities of the company that always enable the company to show better performance than competitors [28].
2.3 A Resource-Based View to Developing a Competitive Advantage
Maintaining the survival of companies in today's competitive environment leaves them with no choice but to gain a competitive advantage. Management theorists have proposed two approaches to competitive advantage, one that is based on environmental opportunities and one that is based on the internal capabilities of the company [23]. Numerous studies by researchers in the last two decades, such as Wernerfelt [29]; Barney [27]; Byrd [30] showed that competitive advantage based on the company's internal capabilities is the best source for competitive advantage and was the basis for strengthening the resource-based view. According to this approach, both the external environment and the internal characteristics of companies will have a significant impact on the success of companies [31]. The resource-based approach pays attention to the internal characteristics of companies and is considered as a basis for creating value for the use of tangible and intangible assets within the company's structures. In fact, according to this approach, the company's strategies are based on internal resources and the development of capacities to exploit intangible assets through which companies in a competitive environment can achieve a competitive advantage. In other words, when the market is constantly changing and the competition in it is increasing, going back and looking back for guidance and guidance in making strategic decisions will face many problems. For example, Porter's Competitive Forces model [32] used five external factors that underlie strategic decision-making. These factors include the bargaining power of resource suppliers, the bargaining power of customers, the threat of new companies entering the market, the threat of the presence of alternative goods, and the competition of companies with each other in the field of industry. Unfortunately, in a dynamic environment, paying attention to these factors cannot provide the necessary guidance for making strategic decisions, in a reasonable way, or even be useful in the allocation of resources of these companies [33]. But in line with the resource-based view, focusing on resources within the company and identifying its strengths, especially the irreplaceable set of resources such as knowledge enhancement; Innovators and human resource capabilities of decision makers can be strategic options based on resource allocation and distribution to gain a competitive advantage in a changing market and competitors.
2.4 Product Market Competition
The concept of competition should include all forms of competition (including market transactions, auctions, etc.), competitive instruments (including price; commercials; research and development; mergers and acquisitions) and competitive objectives (including interests, market share, control). Company, advertising and survival) [34]. The competitiveness of the product market means that different companies are in close competition in the production and sale of goods and its goods are not much superior to each other, because if not, the market tends to monopoly or multilateral monopoly [2]. Market competition can also be considered as market power. Accordingly, market power means the monopoly power, the multilateral or competitive monopoly of a company [35]. Also, competitiveness can be defined as the possibility of achieving a good position and stability in global markets, which shows the ability to gain a competitive advantage in the market. Previous studies over the past few years such as Singla and Singh [36]; Iqbal et al [36] and Laksmana and Yang [37] have shown that competition in the product market is considered as a kind of extra-organizational governance mechanism and an important and vital factor in the decisions of information disclosure by companies. Competition in the product market, on the one hand, forces companies in similar industries to seek information from competitors and, on the other hand, to hide their information in order to have a competitive advantage. Competition in the product market not only makes companies extensively dependent on external competitive advantage, it also encourages owners to strengthen internal corporate governance mechanisms and reduces the opportunistic behaviors of managers. Thus, competition in the product market is a substitute for internal governance that reduces agency costs [38]. Hart [39] argues that competition in the product market can be used as an effective regulatory and regulatory mechanism to control agency problems. The reason for this is that competition in the product market increases the likelihood that companies with high costs will go bankrupt [40].
2.5 Development of Theoretical and Experimental Research Hypothesis
The competitiveness of companies has been introduced by many researchers as a multidimensional concept [41]. Booth and Philip [42] divide the factors affecting competitiveness at the enterprise level into two categories in the form of technology-based approaches and approaches based on competencies and capabilities. They see technology on the one hand as improving efficiency and on the other as a capacity to develop strategic capabilities for companies. Liu and Jiang [43] stated that by combining capabilities and technology, a resource-based view will be able to help increase competitive advantage. In fact, technological capabilities based on the resource-based view were proposed by Teece et al [44]. This capability includes strategic areas of companies' competitive functions, which help to create and develop valuable resources. On the other hand, technological capability based on the resource-based view, also to participate in the integration; Creating and reshaping internal and external competencies to respond and respond quickly to the environment and enables companies that have such capabilities to reflect their ability to enter the market in order to gain a competitive advantage [45]. In order to expand the relationship between technology capability and product market competition based on a resource-based perspective, it should be stated that creating coherence in the development of internal resources and alignment with external resources puts the company in a position to gain a competitive advantage. As stated by Wernerfelt [29] and Barney [46], each company is a collection of resources and capabilities; Resources are input factors that are used to achieve business goals and the capabilities of the company, that is, the company's ability to use resources, it can enhance a company's competitive performance, both in terms of innovation and in terms of product effectiveness. In this regard, Grant [47] and Makadok [48] point out that while sources are the main units of analysis, but in fact, companies have a competitive advantage by integrating them to create technological capabilities, because technological capabilities enable the creation of knowledge and innovation to achieve greater productivity, and having such capacities can help to make the company more competitive in the competitive market. It should be noted that the main advantage of focusing on resource-oriented in developing the relationship between technological capability and the effectiveness of the product market competition of knowledge-based companies is the non-transferability of knowledge or the so-called localization of knowledge that he company is based on investing in its technology infrastructure and enables the company to gain a competitive advantage [10]. Studies such as Dotta et al [49] and [50] and Li et al [51] based on a resource-based view focusing on advanced technology at the heart of technology capabilities with the aim of enhancing competitive advantage, relative to the company's technology characteristics as its technical efficiency. They have conceptualized other companies in turning R&D resources into innovative products. These researchers realized that without sufficient technological capabilities, investing in R&D resources alone could not create a sustainable competitive advantage because this investment could be replicated by competitors [10]. In fact, technological capabilities in the form of technical efficiency over competitors meet the requirement of a resource-based view to a source of sustainable competitive advantage, because the existence of such capabilities in a company's internal processes usually through practical learning related to internal development path. They find that it is not possible to pass it on to companies or to be imitated by competitors [52]. Through hands-on learning, a company's unique understanding of successful development processes emerging through prior knowledge leads to a competitive advantage in creating new knowledge in the same research direction [53]. Given the distinctive market and technological characteristics of knowledge-based companies operating at the capital market level, the unparalleled and non-transferable technological capability of a company at the capital market level is certainly the main source of its competitive advantage. The advantage of sustainable competition will not affect the manager's decision to disclose information in the form of financial reporting, because a company with such an advantage over competitors, firstly, by disclosing information in a timely manner, seeks to gain a competitive advantage and a greater share of the capital market, and secondly, through innovation, seeks more stability in product market competition [27]. Therefore, the existence of technological capabilities helps to raise the level of imitation and non-transferable capabilities and brings a competitive advantage to companies in the product market. Based on this, the research hypothesis states:
v The first hypothesis of the research) Technological capabilities have a positive and significant effect on the product market competition of knowledge-based companies in the capital market.
But if the approaches are based on the level of proprietary management thinking, the company will not show much interest in pivotal development in all matters of the company, especially information technology, because managers with managerial fortifications seek long-term tenure to maintain stability in the conditions under their management, they are in the managerial position of the company. By focusing on the goals of the board of directors and meeting the level of relative satisfaction of the shareholders, these managers try to prevent challenges and fundamental changes in the company's performance by controlling things. Shleifer and Vishny [54], while stating that managers do not want to maximize shareholder wealth, based on their theory of representation and research, stated that managers use their authority to achieve their personal goals to establish their position and value the company does not pay attention. They consolidate their position through special investments that have little risk and thus show that they play a valuable role in the interests of shareholders. The existence of these approaches indicates a superficial fortification to maintain and strengthen the managerial position. According to Marouan [55], fortification is a kind of thinking related to the strength of the manager's position and all the behaviors that lead to job retention; Increases freedom of decision-making and the preservation of personal interests. On the other hand, Lin et al [56] examined the effective role of managerial fortification on product market competition and proposed two very important reasons in this regard. First, the management entrenchment makes the disclosure of company information in the direction of corporate governance mechanisms one-sided and exclusive, and causes information to be provided to shareholders based on the amount that the company wants, and secondly, the reason for fortification and its impact on reducing product market competition is the lack of a dominant and integrated culture; Technology-based; They stated strategies appropriate to the market. In other words, Lin et al [56] analyzed the two axes of corporate representation functions and described managerial entrenchment as the result of unbalanced company structures in a competitive market. While Tyrol [57] focused on individual characteristics influencing managerial entrenchment such as narcissism and short-sightedness, managers with such characteristics sought to strengthen their position by lobbying board members and increasing their share of managerial property, by maintaining the status quo, they create a level of information monopoly to overestimate the impact of favorable events on the firm's cash flows and underestimate the likelihood of adverse events and development, They seek to improve short-term profits to increase stock prices and to lose long-term stock values, as these managers attribute the maintenance of their current position to maintaining the relative satisfaction of shareholders that capital expenditures and investment in research and development are considered to be in conflict with their managerial aspirations. Under these conditions, research and development costs are reduced, and this can reduce the level of competition in the product market, because the company, due to the loss of its competitiveness, tries to prevent the disclosure of its desired information. From exposing the bad news of their actions in the market. Therefore, based on the explanations given, the second hypothesis of the research is:
v The second hypothesis of the research is that the entrenchment of the CEO moderates the positive effect of technology-based capabilities on the product market competition of knowledge-based companies in the capital market in a negative direction.
2.6 Research Background
Rahman et al [58] conducted a study entitled "Investigating the effect of product market competition on companies' profitability". This research was conducted in the period of 1996 to 2016 and 107018 observations of the year of the US Stock Exchange were examined. The results of this study showed that the in-house individuals of companies in highly competitive industries earn more extraordinary profits. The results showed that the existence of mechanisms of research and development intensity and increasing training costs is the most important factor in the sustainable development of the company's competitiveness in the product market, that the future, it can help increase the company's profitability by developing financial transparency, such as the readability of financial reporting, and increase the company's share of the capital market. Jiang et al [59] conducted a study entitled "Investigating the Impact of Stakeholder Communication and Technological Capabilities". The study, conducted between 2003 and 2014, looked at a sample of 126 listed companies on the China Stock Exchange. In this study, in order to measure the research variables, partial least squares analysis (PLS) was used. Their research findings showed that it improves the ability to communicate closely with the company's innovation stakeholders. Sahi et al [60] conducted a study entitled The Study of the Moderating Role of Entrepreneurial Orientation to the Impact of Technology Capabilities and the Intensity of Product Market Competition. The study involved 164 CEOs of US capital market companies, which used partial least squares (PLS) analysis to fit the model. The results showed that the existence of entrepreneurial orientation as a managerial insight in companies, causes the positive impact of technology-based capabilities on the intensity of product market competition, intensifies in a positive direction. Fung [10] conducted a study entitled "Investigating fraudulent financial reporting on technology capabilities based on a resource-based view." In this study, 141 US stock exchange companies in the period 1998 to 2011 were examined. In this study, regression was used to measure fraudulent financial reporting and data envelopment analysis (DEA) was used for technology capabilities. The results showed that according to the source-based view, technology capabilities have a significant negative impact on fraudulent financial reporting. In addition, the likelihood of fraud is irrelevant to the scale of returns on technology activities, because investing in R&D resources is not in itself a source of sustainable competitive advantage. Ramezan Ahmadi et al [61] conducted a study entitled "Study of the effect of macroeconomic variables and product market competition on profit quality: Structural equation approach." The study period is the years 2006 to 2015 and the selected sample is 70 companies. For data analysis, structural equation modeling with partial least squares (PLS) approach and PLS software has been used. The results show that product market competition directly and indirectly (through financial performance mediator) has a significant positive effect on profit quality, but through the mediator variable of capital structure, it has a significant negative effect. Also, direct impact is stronger than indirect impact. Other research findings indicate that macroeconomic variables have a positive effect on financial performance through mediation, but a negative effect on profit quality through mediation of capital structure. Also, macroeconomic variables have a direct negative relationship with earnings quality, but this relationship is not significant. Valiyan et al [62] conducted a study entitled “Designing an Organizational Capabilities Approach Model Based on Strategic Reference Point Theory”. In fact, this study sought to design a model based on the approaches of organizational capabilities strategies with respect to the dimensions of knowledge organizations, traditional and knowledge and industrial attitudes. The approach of this research is based on the philosophy of science (Epistemology) and the philosophy of the universe (Anthropology). In other words, based on the review of the organizational capabilities strategy literature and the study of the subject libraries, it was determined that an integrated model in line with the context of organizational capabilities has not been presented and this study sought to design an organizational capabilities model using strategic reference points. Based on this, first the dimensions of this research, including knowledge organizations, traditional organizations, knowledge attitude and industrial attitude, were explained, then we tried to use a coordination model based on strategic reference points, coordinated types of each capability strategies. Therefore, following the research of Fung [10], this study has used data envelopment analysis to measure the variable of technological capability, which can be used as a basis for evaluating technical efficiency in increasing the development capabilities of companies to attract and create new resources and contribute to the stability of the capital market.
3 Methodology
The present study is an applied research in terms of purpose and quasi-experimental post-event research in the field of positive accounting research in terms of data collection method. Using data envelopment analysis method, the variable of technological capabilities was first measured. Then, based on multivariate regression based on Eviews software, the research hypothesis was tested. The statistical population studied in this study consists of knowledge-based companies listed on the Tehran Stock Exchange during the years 2015 to 2019. After applying the above restrictions, 79 companies were selected as the research sample. The data of the present study were extracted from the compact discs of the statistical and video archives of the Tehran Stock Exchange Organization, the website of the Tehran Stock Exchange and other related databases, as well as from the new Rahavard software. The final analysis of the collected data was performed using Eviews software.
3.1 Research variables
3.1.1 Independent Variable
Technology-Based Capabilities Based on a Resource-Based Approach
In his research, Makadok [48] examined the role of technological capabilities as a criterion for the development of competitive capabilities/sustainability of companies, emphasized their role in internalizing coherent competitive processes, and introduced them as a factor in promoting economic returns of the companies. Competitive processes provides the company's economic returns through more efficient resource utilization compared to the opponents. Similarly, Capabilities will lead to gaining a sustainable competitive advantage in terms of the company’s technical efficiency in converting organizational resources into product-resources because these capabilities (embodied in intra-organizational processes) cannot be transferred or imitated. Following this discussion, Dutta et al [49] measured the capabilities of a company (defined as the company’s technical efficiency in converting the input to output) over its competitors. Relying on the research by Dutta et al [50] and Li et al [51] on RBV, this study measures technological capabilities in terms of competitive capability criterion as the relative technical efficiency of a company by which it transforms R&D resources into an innovative product. Following the study by Griliches [63], the cumulative R&D resources of Company i in Year t, i.e., , are defined as follows:
| (1) |
| (2) | ||||||
| (3) |
| (4) |
Where is equal to the market share of company j in industry i. The following equation is used to calculate the company's market share:
| (5) |
Where is the sales revenue of company i and s is the total sales revenue of the company in the industry in which company i operates. The HHI standard is a degree of focus on an industry and is a measure of the level of competition. To facilitate the interpretation of the results, multiply the HHI index by (-1). Therefore, a higher HHI index means a higher level of competition in the product market.

3.1.3 Moderator variable
Entrenchment of CEO
Entrenchment is a concept based on possessive and entrepreneurial behavior in maintaining a job position that has been nicknamed organizational behavior in recent years. According to Marouan [55], the CEO's entrenchment refers to the strengthening of the managerial position by the individual and includes all behaviors that lead to job retention, increased freedom of decision, and personal gain. Based on this concept, to measure the strength of the CEO following the research of Di Meoa et al [64] and Bebchuk et al [65] are calculated from the virtual variables 0 and 1 and based on the three criteria of CEO tenure, managerial ownership and dual. The use of a virtual variable based on these three criteria is done because it is expected to reduce the disorders of each of these three different dimensions [66]. Now each of the three criteria of the term of office of the CEO, managerial ownership and duality of the post of CEO is explained.
§ CEO tenure
The CEO tenure increases over time [67]. At the beginning of their tenure, CEOs prioritize the need to develop managerial skills to meet new job needs. After that, they may try to eliminate their opportunistic motives. Also. Accordingly, following the research of Di Meoa et al [64] and Bebchuk et al [65], 0 and 1 are used to measure this variable, so that if the CEO has been a CEO for 3 years or more have a company number 1 otherwise they are given the number 0.
§ Managerial ownership
Based on previous research, Di Miguel et al [68] argue that CEOs have managerial stability with a moderate level of managerial ownership. When managerial ownership is below a certain boundary, capital markets reduce their opportunity for control by controlling managers' motivations. And in this case, agency costs will be reduced. But if managerial ownership is above a certain threshold, the interests of managers are likely to take precedence over the interests of shareholders. According to most models, the measure of managerial ownership is calculated based on the percentage of shares held by managers to the total number of ordinary shares held by shareholders. However, this study follows the model of Di Miguel et al [68] who used the firm value criterion to measure managerial ownership and determine the value of companies in the range of managerial ownership fluctuates between 18.8% and 50.06%. On this basis, if the percentage of managers' share of the total ordinary shares is in the hands of shareholders in this range, the number 1, otherwise the number 0 will be assigned to it.
§ DUAL
According to the research of Gompers et al [69] and Bibchuk et al [65], the duality of CEO position is calculated as a two-dimensional criterion of 0 and 1. If the CEO is the chairman or vice-chairman of the board of directors, the number 1 will be assigned to him, otherwise the number 0 will be assigned to him.
Finally, to calculate the CEO's entrenchment, if there are at least two of the three factors mentioned in the company, the number 1, otherwise the number 0 is assigned to it.
3.1.4 Control variables
Based on the findings of the literature related to this research and following the research of Fung [10]; will examine the following control variables in this study:
v Growth expectation which is measured by the ratio of book value to market value, reflects investors' expectations for the company's future performance. Market-level companies may lose their capabilities because they do not have the technology capabilities and given the high expectations of investors from these companies, reduce product market competition. Therefore, product market competition is expected to increase with , as companies increase investor expectations that be at a high level in terms of product market competitiveness index [10].
v Net operating assets of the ratio of the total value of shareholders' shares plus operating liabilities (accounts payable; pension and salary liabilities; realized unpaid expenses); minus cash securities are calculated on the basis of sales. Thus, product market competition is expected to be directly related to [70].
v Liquidity , which is defined as cash and cash equivalents divided by current liabilities. Product market competitiveness is expected to increase with, because a severe liquidity constraint weakens the firm's competitiveness by reducing the firm's ability to do so [10].
3.2 Research Models
Given the nature of the research variables and the hypothesis, Equation (7) is used to measure the model of the research hypothesis:
| (7) |
| (8) |
Technical efficiency of 2019 | Technical efficiency of 2018 | Technical efficiency of 2017 | Technical efficiency of 2016 | Technical efficiency of 2015 | Maximum efficiency (MAX θ) | Decimation |

0.2409 | 0.4731 | 0.6276 | 0.8187 | 0.816 | Bad | Second decile |

0.9485 | 0.864 | 1 | 1 | 1 | Good | Fifth decile |
0.8654 | 1 | 0.9244 | 0.6236 | 0.718 | Good | Sixeth decile |
1 | 1 | 1 | 0.9328 | 0.779 | Perfect | Seventh decile |
1 | 0.894 | 1 | 1 | 1 | Perfect | Eighth decile |
0.9938 | 1 | 1 | 1 | 1 | Perfect | Ninth decile |
1 | 1 | 1 | 1 | 1 | Perfect | Tenth decile |
In this analysis, the technical returns of R&D cost and investment functions were compared based on the mentioned criteria, whose returns score was obtained, then the bad and medium grade functions are evaluated together and the average grade technical return is calculated. In this model and based on the analysis of the above Table, a specific coefficient is considered for each of the input variables, because the effect of all input variables on output (profitability) is not the same. As mentioned, the calculated value for technical efficiency is in the range of zero to 1. Companies with a technical efficiency score of one are companies that are highly efficient, and companies with a technical efficiency score of less than one are below the efficiency threshold and must achieve technical efficiency or technical efficiency by reducing costs or increasing investment in research and development. The purpose of calculating technical efficiency is technology-based capabilities based on R&D functions. Because affected by these properties, more or less than the actual value is calculated. On the other hand, the good grade is compared with the bad grade and the average grade, and the technical efficiency of the good grade is calculated, and finally the technical returns of the excellent grade are evaluated with all R&D functions, and the higher and lower technical return score is calculated. Because according to the research hypothesis, determining the level of technology-based capabilities is calculated based on the technical efficiency of research and development costs and investments. Next, by comparing inefficient functions with reference units, the optimal value of each output is obtained. In this way, it is determined how much each inefficient function increases its output so that its efficiency reaches the size of its reference set. In the Table below, the inverse technical return of companies R&D in the form of specific deciles is used, so that if the inverse value of the return is more than one, it means that that decile is inefficient. Note that due to the large number of data under study, by decoding and inverting it in this section, the inefficient research and development functions of companies located in these deciles should be determined. For example, the efficiency of the second decile is 1.0818, which indicates that it is inefficient at 0.0818 and must increase the output by the same amount to improve its efficiency.
Based on the obtained results, considering the inverse of the technical efficiency of the deciles performed in terms of maximum efficiency, low performances can be identified in the Table.
Thus, as described in the measurement of technology-driven capabilities, companies that had a technical return of more than 1 in the inverse of Table (3), or in other words (TEVit <1), represent the low technical returns of companies. It is examined that expresses the fact that these companies do not have core technology or at least have low technologies, based on which they are assigned the number 0. Unlike companies located in deciles that are it means that the capability of technology-based technology based on technical efficiency is largely unmatched. And on this basis, they are assigned the number 1. In simpler terms, given that the companies in the deciles (TEVit <1) have earned 0, they are assigned the number 0, which means they are not technology-oriented.

Because for the first model, the significance level of the F-Limer test is greater than the error of 0.05, so to estimate the first model of the research, the combined data method should be used. Therefore, in the first model, there is no need to use Hausman test to determine the type of panel data (fixed or random effects method). However, in the case of the second model, because the significance level of the F-Limer test is less than the error of 0.05, it is necessary to use the panel data method to estimate the second model of the research. However, it remains to be seen whether the fixed effects pattern is more appropriate for the data or the random effects pattern. The Hausman test is used for this purpose.
Table 8: Results of Hausman Test for the Second Model of Research
Chi-square test statistics | Degrees of freedom | Significance level | Test result |
0.001 | 6 | 0.999 | proving a theory |
According to Table (9), because for the second model, the significance level of Hausman test is greater than the error of 0.05, so the use of random effects pattern is superior to the use of fixed effects pattern. Therefore, a random effects pattern is used to fit the second model. One of the important assumptions of the regression model is the assumption of homogeneity of the residual variance. If this condition is not met, ordinary least squares estimates do not have the characteristic of efficiency (minimum variance). To test this default, the likelihood ratio (LR) test in stata software is used. The null hypothesis in this test is the homogeneity of the residual variance that if the significance level of this test is more than 0.05, the null hypothesis is confirmed. The results of this test are presented in Table (9).

First model | 3658.96 | 78 | 0.001 | Reject the null hypothesis |
Second model | 5836.44 | 78 | 0.999 | Confirmation of the null hypothesis |
The results of the likelihood ratio test in Table (10) show that because the significance level of the test for the first model of the research is less than 0.05 error, therefore for this model there is a problem of variance of the residual variance. Therefore, GLS (Generalized Least Squares) method is used for estimation in this model. However, in the second model of the research, the assumption of variance homogeneity with a five percent error is confirmed and as a result, there is no problem of variance inequality of the residuals for this model. Therefore, for estimation in this model, we will use the ordinary least squares method. By default, the remainder of the model is normal, the statistical distribution of the error statements should be normal. This test is performed after estimating the model using the Jarque-Bera test.

Considering the significance levels of the jb test of the model (numbers in front of the probability section in Figures 3 and 4), because these values are greater than 0.05, then at the 95% confidence level, the assumption of the remaining normality of both research models is confirmed. To ensure that there is no alignment problem between the independent variables, the alignment test using the variance inflation factor (VIF) was also examined. Since the values of this statistic are less than 10 for the explanatory variables, there is no alignment between them. Also, in order to test the correlation between the error components of the model, the camera-Watson statistic was used, the results of which are presented in Tables (10) and (11). If the value of the Watson-Camera statistic is between 1.5 and 2.5, there is no correlation. Based on this, the results of the research hypotheses test are presented in the form of Tables (10) and (11), P. Considering the value of F statistic in this figure, it indicates the general significance of the first regression model fitted at the 5% error level. The value of the Watson-Durbin statistic also indicates that there is no problem of autocorrelation between waste statements. As can be seen in this picture Estimation coefficient and t-statistic related to technical variable efficiency (TVE) at the error level of 5%, positive and significant, which indicates the positive effect of technical efficiency of technology-based capabilities on product market competition. Therefore, the first hypothesis of the research that technology-based capabilities have a positive and significant effect on the product market competition of knowledge-based companies in the capital market is confirmed.
