Introduction
Perpetual competition refers to the sustainable competitive advantages, attributes, or capabilities of company assets that are difficult to copy or surpass and provides a long-term or advantageous position that is superior to competitors [1,2]. Perpetual competition generally goes through three stages: the formation of competition, the maintenance of competition, and the demise of competition. Several pieces of the literature have been reported on the study of sustainable competition. Xu et al. revealed the characteristics of China and India's sustainable advantages and clarified that China and India have different impacts on the imports of related fields in the United States [3]. Zeng et al. proposed that the role of information systems was played in developing countries and sustainable information infrastructure [4]. Feng et al. pointed out that if innovation and scientific research continuing in the high-tech industry, enterprises would maintain a competitive advantage [5]. uethongchai et al. reported service industry organizations used big data analytic to build the ability to gain a competitive advantage and the ability to respond quickly and accurately to market demands [6]. Prabowo et al. identified the ability to develop new products based on the perspective of inactive issues gave small medium-sized enterprises various competitive advantages [7]. Gross-Gołacka et al. attempted to improve the sustainable competitive advantage for enterprises by improving the knowledge ability of managers [8]. Hu et al. argued industry-level international mergers and acquisitions had a significant negative impact on the sustainable performance of the acquirer's competitors [9]. Erokhin et al. established policy measures to competitive advantages in agricultural field [10]. All the literature is basically based on different industries for research, but does not analyze the impact of core technological capabilities on the establishment of sustainable competitive advantages of the enterprise as a whole, so there is still a vacancy in this area of research. e core technical capabilities are the necessary and sufficient capabilities to ensure that organizations can take advantage of changing technology and service markets to gradually gain business advantage [11,12]. ere have been many reports on the research of core technical capabilities. Jin et al. (2020) considered the impact of cluster technology innovation capability on the long-term development of the cluster, and found that the improvement of cluster technology innovation capability promoted the development of the industry [13]. Zhou et al. used theory to create a theoretical framework of data-based core technical capabilities [14]. Wu et al. determined that the core technical capabilities were critical to the performance of seller-managed retail companies [15]. Chen et al. found that core technical capabilities played a very important role in improving the competitiveness of enterprises [16]. Martínez-Román et al.
(2017) showed the adoption of technology, the entrepreneurs' motivations, business plans and cooperation in research, and development activities were important factors [17]. Heidari et al. studied the impact of corporate leadership and teams on corporate core technology [18]. López-Cabarcos et al. found that technological capabilities had a moderating effect on the performance relationship of knowledge companies [19]. It is not difficult to see from the existing research results that the core technology capability of an enterprise is a prerequisite for sustainable competition and an important guarantee for the development of the company. erefore, it is of great significance to study the impact of core technology capability on the sustainable competitive advantage of an enterprise.
Based on the summary of previous research results, the characteristics of high-tech enterprises and theories based on market, management, marketing, strategy, and organizational innovation were deduced, the constituent elements of the core technological capabilities of high-tech enterprises were clarified, and the theoretical model and related research hypotheses were put forward to identify the core technological capabilities of high-tech enterprises under sustainable competitive advantages. rough research on high-tech enterprises and model verification through questionnaires, the revised model was finally obtained, which will provide a theoretical basis for the company's core technology capability construction and sustainable development research. e remainder of this paper is organized as follows. Section 2 provides the method of this research. Section 3 presents the results of this research.
is is followed by discussion in Section 4. Finally, the conclusions of this study are given in Section 5.

Methodology
e literature research method is used to summarize relevant documents such as technical capabilities and sustainable competitive advantages. Based on relevant literature, combining the theoretical knowledge of market, management, marketing, strategy, and organizational innovation to study the mechanism of the impact of core technological capabilities on sustainable competitive advantage, and put forward the theory of identifying the core technological capabilities of high-tech enterprises from the perspective of sustainable competitive advantage.

Questionnaire Survey.
e target of this investigation and research is mainly high-tech enterprises, including electronic information technology companies, new energy technology companies, biomedical technology companies, new material technology companies, aerospace technology companies, and high-tech service companies; those are the six types of high-tech industries. e research is conducted through field surveys and questionnaire surveys. Among them, the main objects of field investigation are the company's senior management personnel, who are relatively familiar with the company's business processes and development and operation methods. e main objects of the questionnaire can be corporate executives or department managers, who are very familiar with the company's operating conditions. In order to ensure the validity of the data, a total of 320 questionnaires are distributed in this preliminary survey, and 300 questionnaires are withdrawn, excluding questionnaires with obvious errors and incompleteness; 266 valid questionnaires are finally obtained, accounting for 88.6%, which meets the relationship between the number of survey samples and the number of measurement items.
Pre-survey: in order to ensure the rationality of the survey data, first after a small-scale pre-survey including a questionnaire survey and a small-scale interview, the expression and understanding of the questionnaire is modified, and then a large-scale survey is conducted. e questionnaire is structured, which contains the following: (1) Explanation of the questionnaire, mainly to inform the interviewee about the purpose, significance, and confidentiality measures of the survey, and hope that the interviewee can fill out the questionnaire fairly, justly, and seriously. (2) e main content of the questionnaire involves three parts of the core technological capabilities, organizational innovation and sustainable competition of high-tech enterprises.
ere are 36 questions of which mostly single-choice questions, and the content of the questionnaire comes from the literature review. (3) Respondent information is related to the category and position of the company. e questionnaire option adopts a 5-level scale model, 1-5, which means from completely disagree to fully agree.

Reliability and Validity Analysis.
(1) Reliability analysis adopts Cronbach's α coefficient method of Yurdugül (2008), when the coefficient is between 0.7 and 0.8, it indicates that the questionnaire results have a high degree of credibility [20]. When the coefficient is between 0.65 and 0.7, the reliability is within the acceptable range, and when the coefficient is between 0.6 and 0.65, the reliability of the questionnaire survey results is not credible.
2 Discrete Dynamics in Nature and Society (2) Validity analysis adopts the Ratio Statistic Test (RST) method, judging by redundancy and sensitivity [21]. Redundancy degree (RD) represents the independence and redundancy of each indicator. When RD ≤ 0.5, it means the indicator is valid, and the smaller the value, the higher the validity. Sensitivity degree (SD) is the adaptability of different evaluation systems to evaluation indexes. When SD ≤ 5, the indexes are valid.
Due to the large degree of difference between each threelevel indicator, before modelling, all data are normalized. e calculation method used in this case is to adopt an average weighting method for all results, calculate the final score of each indicator, and the normalized interval is [0,1]. e specific calculation equation is shown as follows: In order to effectively reduce the error, the consistency test is performed on all the matrices; the specific calculation equation is as follows: Here, ℷ max is the maximum eigenvalue, which is the average value of Aw i /w i . w i is the fractional vector of the rows of the matrix multiplied by the weight W and sum. Aw i / w i is the divisor of the matrix and its corresponding fraction vector. N is the number of data. e average random consistency indicator RI is used to determine the approximate range of inconsistency.

Analysis of Variance Adjustment Effect.
(1) Analysis of Variance. It is used to study whether the variables controlled by multiple factors have a significant influence on the observed variables, and the influence relationship between the variables can be obtained. Campbell and Kulis's (2018) multivariate analysis of variance is used; if the P value is less than the significance level (0.05), it is considered that there is a significant difference between the control variable and the observed variable [22]. Otherwise, if the P value is greater than the significance level (0.05), it is considered that there is no significant difference between the control variable and the observed variable.
e chromatographic analysis method is used to perform adjustment analysis on the regression model with product term [23]. After adding independent variables or adjusting external variables to regression model 1, the correlation between independent variables and adjusted dependent variables is focused on, and then optimize the values of independent variables and adjusted dependent variables. e paper compared hypothesis model 2 with model 1 and calculated the significance of the overall evaluation index. If both model 1 and model 2 have a significant change or the input variable proportional coefficient has a significant change, this proves that the adjustable factor has a regulating effect on the variable.

Descriptive Statistical Analysis.
e target of this survey and research is mainly high-tech enterprises, which involves six types of high-tech industries. rough field surveys and questionnaires, the basic situation of the interviewed enterprises is shown in Figure 1.
e establishment time distribution of the interviewed companies is relatively average, with the largest number of companies in 10-20 years, accounting for 36.1%. e size of the companies interviewed is mainly concentrated between 200 and 500 people and more than 500 people, accounting for 33.2% and 27.8%, respectively. e industry distribution of the interviewed companies is relatively even, with 96.7% of the companies in the major industries. e largest number is the new material technology industry, accounting for 20.3%, followed by the electronic information technology industry, accounting for 19.1%. e company's annual operating income ranging from 5 to 10 million covers most, which accounts for 34%. All of the above indicate that the results of this survey cover a wide range of industries and involve many companies, which can better explain the actual problems.

Reliability and Validity
Test. It can be seen from Table 1 that the Cronbach values of all variables exceed 0.7, and it can be considered that the questionnaire used in this study has high reliability. As can be seen from Figure 2, the average value of each variable in the questionnaire is higher than the square of the highest value of the correlation coefficient of each variable. Based on the above analysis results, it can be seen that there is no strong correlation between the measurement items in the questionnaires, and this questionnaire has good discrimination validity. Table 2, in order to analyze whether there are significant differences in the market recognition ability, strategic planning ability, management operation ability, all-person marketing ability, dynamic marketing ability, organizational innovation, and sustainable competitive advantage of enterprises with different establishment time, scale, industry and operating income, ANOVA is conducted. e results show that for all variables, the P value is greater than 0.05, and the F value has not reached the significance level, which means that companies with different establishment time, scale, industry and operating income have not produced significant differences in market cognition ability, strategic planning ability, management operation ability, full marketing ability, dynamic marketing ability, organizational innovation, and sustainable competitive advantage. at is, the control variable has no significant effect on the measured variable.

eoretical Model Test
Results. Based on the references and data from the questionnaire, a theoretical model is established to identify the core technological capabilities of high-tech enterprises. As shown in Figure 3, the relationships among market cognition ability, strategic planning ability, management operation ability, full marketing ability, dynamic marketing ability and organizational innovation, and sustainable competitive advantage are established, and each influencing factor has a corresponding fitting coefficient. After establishing the relationship of error variables such as α2 and α5, β5 and β6, c1 and c3, c12 and c14 in the model, it is found that the theoretical model fit index has been improved. To verify its data, as shown in Table 3, the model fit index values obtained after the theoretical model correction are within the acceptable range (GFI index error is 3.75%, which is within the acceptable range). e fit is in accordance with the standard of structural equation.

In model 2, the   Discrete Dynamics in Nature and Society regression coefficient of the product term of market knowledge ability and dynamic marketing ability is 0.061 (P < 0.05), indicating that the product term has a significant impact on sustainable competitive advantage. Dynamic marketing capabilities have a regulatory effect between market knowledge capabilities and sustainable competitive advantage. Table 5 displays the adjustment effect of dynamic marketing capabilities on strategic planning capabilities. For model l, the F test value is 110.659 (P < 0.05), indicating that model l results are significant. e regression coefficients of strategic planning ability and dynamic marketing ability are 0.066 and 0.047, respectively (P < 0.05), indicating that market cognitive ability and dynamic marketing ability have a positive impact on sustainable competitive advantage. In model 2, the regression coefficient of the product term of strategic planning capability and dynamic marketing capability is 0.075 (P < 0.05), indicating that the product term has a significant impact on sustainable competitive advantage. Dynamic marketing capabilities have a regulatory effect between strategic planning capabilities and sustainable competitive advantage. Table 6 shows the adjustment effect of management operation ability on strategic planning ability. For model l, the F test value is 114.567 (P < 0.05), indicating that model l results are significant. e regression coefficients of strategic planning ability and management operation ability are 0.086 and 0.063 (P < 0.05), respectively, indicating that market cognitive ability and management operation ability have a positive impact on sustainable competitive advantage. In model 2, the regression coefficient of the product term of strategic planning capability and management operation capability is 0.074 (P < 0.05), indicating that the product item has a significant impact on sustainable competitive advantage. e management and operation capability has a regulatory effect between strategic planning capability and sustainable competitive advantage. Table 7 describes the adjustment function of the marketing ability of all employees to the strategic planning ability. For model l, the F test value is 96.226 (P < 0.05), indicating that model l results are significant. e regression coefficients of strategic planning ability and marketing ability of all employees are 0.061 and 0.051 (P < 0.05), respectively, indicating that market cognitive ability and marketing ability of all employees have a positive impact on sustainable competitive advantage. In model 2, the regression coefficient of the product term of strategic planning ability and marketing ability of all employees is 0.068 (P < 0.05), indicating that the product term has a significant impact on sustainable competitive advantage; that is, the marketing ability of all employees has a regulatory effect between strategic planning ability and sustainable competitive advantage.  Discrete Dynamics in Nature and Society rough the above data, the original model is simply modified. In the revised model, market cognition ability, strategic planning ability, management operation ability, all-person marketing ability, and dynamic marketing ability can directly affect sustainable competitive advantage, or indirectly affect sustainable competitive advantage through   Figure 4 provides theoretical model for identifying core marketing capabilities of high-tech enterprises from the perspective of sustainable competitive advantage.

Discussion
With the development of economic integration and globalization, and the continuous acceleration of product and technology updates, the competition faced by high-tech enterprises is becoming more and more fierce, and it is more and more difficult for enterprises to obtain sustainable    Discrete Dynamics in Nature and Society competitive advantages. Identifying the core technical capabilities of high-tech companies can help companies grasp the ability to have the most positive effect on sustainable competitive advantage, and make full use of their own resources and capabilities to obtain sustainable competitive advantage. e empirical research results show that for hightech enterprises, enterprises need to focus on building market cognitive ability, strategic planning ability, management operation ability, and full marketing ability, while the dynamic marketing capabilities require companies to make a reasonable allocation according to their own situation. e direct impact of core technical capabilities on sustainable competitive advantage: (1) the market environment that high-tech companies are located has a high degree of uncertainty, in which market awareness can help them obtain detailed consumer and competitor information; (2) strategic planning capability seeks sustainable development for the enterprise through the formulation and execution of strategies; (3) members within the enterprise communicate and collaborate with each other to realize the benefits of the enterprise, and realize the ability of the enterprise to adapt to and adjust to the market under the effect of dynamic marketing capabilities, thereby helping the enterprise to form a sustainable competitive advantage. erefore, hightech enterprises have the most direct and most significant impact on sustainable competitive advantage through market awareness, strategic planning, management and operation capabilities, full-person marketing capabilities, and dynamic marketing capabilities.
Indirect impact of core technical capabilities on sustainable competitive advantage: the ability of strategic planning has the greatest impact on sustainable competition, because the organizational innovation of enterprises has great uncertainty and risk, which is more obvious in the turbulent market environment in which high-tech enterprises are located. is explains the reason why strategic technological capabilities have the greatest impact on organizational innovation [27,28]. e management of enterprises also has a significant impact on organizational innovation [29,30]. e performance of enterprises formed by organizational innovation is getting higher and higher, and the competitive advantage is becoming more and more obvious; it can be seen that organizational innovation of enterprises inevitably has a significant impact on sustainable competitive advantage [31]. e high-tech enterprises are taken as the research object, and the relationship between technological capability, organizational innovation, and sustainable competitive advantage are studied. However, due to time, experience, and other factors, there are still some shortcomings and deficiencies: (1) on the basis of consulting the relevant literature, the rationality and universality of the measurement items of individual variables still need to be verified in future research and analysis, although these factors have passed the reliability and validity test in the process of empirical analysis. (2) e theoretical model of this study only analyzes the impact of four technological capabilities on organizational innovation and sustainable competitive advantage, and does not conduct in-depth analysis on the different levels of various technological capabilities. Whether different contents of various technical capabilities will have different degrees of impact on organizational innovation and sustainable competitive advantage will become a focus of future research.

Conclusions
rough consulting a large number of literatures on sustainable competition, combining with the characteristics of high-tech enterprises and deducing based on the theories of market, management, marketing, strategy, and organizational innovation, a theoretical model and related research assumptions are proposed to identify the core technological capabilities of high-tech enterprises. e methods of factor analysis, correlation analysis, and structural equations of 266   Discrete Dynamics in Nature and Society survey data of related companies are used to confirm the validity of the model and revise. e research conclusion are as follows: high-tech enterprises' market cognition ability, strategic planning ability, management operation ability, all-person marketing ability, and dynamic marketing ability have a direct and positive impact on sustainable competitive advantage, and organizational innovation also has an indirect impact on sustainable competitive advantage. e degree of impact on the sustainable competitive advantage is in order of market cognition ability, strategic planning ability, management operation ability, full marketing ability, and dynamic marketing ability. Dynamic technical capabilities can enhance market cognitive ability, strategic planning ability, management and operation ability, all-person marketing ability, and dynamic marketing ability, and have a positive impact on sustainable competitive advantage.
At the theoretical level, the theoretical research on core technical capabilities is enriched, on the one hand, through comprehensive evaluation and analysis of relevant research on the existing technical capacity components, the core technical capacity components of high-tech enterprises are clarified. On the other hand, by sorting and analyzing existing models, summing up previous research results and related theories, in-depth analysis of the impact of technological capabilities on sustainable competitive advantage, and proposing a theoretical model to identify the core technical capabilities of enterprises from the perspective of sustainable competitive advantage to expand relevant research in this field. At the practical level, the intensified competitive environment has greatly affected the application of the company's core technical capabilities, the theoretical model established to identify the core technical capabilities of high-tech enterprises can help companies effectively identify the core technical capabilities that can form sustainable competitive advantages, and then build the core technical capabilities of enterprises to guide the direction.
