The Influence Of Corporate Income Tax Incentives On The Performance Of Integrated Circuit Enterprises

Integrated circuit technology has become a common modern science,which has brought great changes and changes to social development and daily life.So,scientific and technological innovations in the field of integrated circuits are crucial for promoting comprehensive innovation in China’s life as a whole,implementing industrial transformation and modernization,and building an innovative country.Integrated circuit is the most representative subcategory in the field of information technology.At present,China has entered the ranks of the fifth information technology revolution.However,this does not mean that China’s integrated circuit industry has a high international competitiveness.On the contrary,its development is relatively backward,and its industrial base is weak.Because China has less investment in this field,the core competitiveness of the integrated circuit industry is weak.Implementing an innovation-led development strategy,break through the U.S.monopoly on the global high-tech industry,and avoid the recurrence of "ZTE" and other problems,the state and government encouraged integrated circuit enterprises to increase investment,and granted special income tax preferential policies.This paper selects the income tax preferential policies applicable to integrated circuit enterprises and carries out research based on the paradigm of "income tax preferential policies-behavior-economic consequences".This paper focuses on examining the relationship between income tax incentive policies,R&D investment and the performance of China’s integrated enterprises,and focuses on the intermediary effect of R&D investment,In order to find out the problems of the current income tax preferential policy in the process of stimulating the R&D investment and improving the enterprise performance of integrated circuit enterprises,and put forward corresponding countermeasures to improve these problems,so as to promote the better development of integrated circuit businesses.Firstly,based on the theory of tax regulation,externality and other economic theories,a relatively complete theoretical analysis framework is constructed,and the necessity,rationality and effectiveness of using corporate income tax preferential policies to stimulate the R&D and innovation of integrated circuit enterprises are theoretically expounded;Secondly,this paper analyzes and evaluates the current situation of China’s integrated circuit enterprises enjoying income tax preferences,and points out a series of problems in the current corporate income tax preferential policies for integrated circuit enterprises in China,such as the tax preferential policies are too biased on direct preferences,the coverage of the R&D expenses plus deduction policy is small,the tax preferential policies are scattered and lack of coordination among policies.Finally,an empirical test is carried out with the relevant financial data of 59 listed companies in China’s integrated circuit industry from 2012 to 2021.The test results show that: 1.The corporate income tax preferential policy plays a vital improvement influence on the performance of integrated circuit enterprises;2.The corporate income tax preferential policy can promote integrated circuit enterprises to increase R&D investment;3.Investment in business R&D has a positive mediating effect on the income tax relief process in terms of increasing the performance of IC firms.On the basis of the status quo analysis and empirical test conclusions of the previous article,the thesis gives the following policy recommendations: expand the support of corporate income tax preferences,expand the scope and proportion of indirect tax preferences,improve the R&D plus deduction policy and strengthen the integration and simplification of corporate income tax preferences.
