Study On The Mechanism And Effect Of Tax Incentives On Semiconductor Industry Innovation ——Take 37 Listed Companies

Semiconductor enterprises are the indispensable foundation of high-tech enterprises,which are widely used in all kinds of top science and technology fields.In the past decades,China's semiconductor enterprises have achieved considerable development.In recent years,with the increase of downstream consumer demand,China's semiconductor consumption is also increasing.Increasing domestic demand in a semiconductor in China's self-sufficiency rate is always in a low level,so the Chinese government to be included in the "made in China 2025",hope enterprise can grasp the main steps of semiconductor companies chain technology,increase the rate of domestic alternative,master the core technology,avoid because of "their" technology,The government hopes that will lighten the burden of r?d tax semiconductor companies,in recent years introduced a lot about semiconductor companies policies prevailing worldwide tax policies,reduce the tax burden of semiconductor companies,improve the enterprise research and development efficiency and the quality of the product,but the tax preferential policies can truly to enterprise's r?d spending has significant incentive effect,The main problem of this paper is whether there is heterogeneity in the incentive effect.The writing ideas of this paper are as follows.First of all,determine the subject content and research method of the research,read domestic and foreign literature,summarize the research status,determine the research content,domestic and foreign literature research tax incentives on innovation effect of a lot of incentives,but less research on semiconductor enterprises;Secondly,the theoretical basis of the existing research is studied to lay the theoretical foundation of the paper.Then,the status quo of semiconductor enterprises in China and the tax preferential policies enjoyed in recent years are analyzed,and the problems existing in the development of enterprises and the possible causes of the problems are analyzed.The empirical part choose 37 listed company data to construct a fixed effect model of 2012-2020,preliminary explore the preferential tax policies for semiconductor,the influence of corporate r?d input from equity level analysis of the nature of the state-owned and non-state-owned enterprises incentive effect difference and analysis from the Angle of scale level different incentive effects of large and small and medium enterprises,Finally,puts forward some Suggestions according to the empirical results.Through the above model construction and conclusion analysis,the following conclusions can be drawn: First,the intensity of tax incentives has a significant positive incentive effect on semiconductor enterprises' R?D investment.Second,the incentive effects of tax incentives on non-state-owned enterprises and non-state-owned enterprises are different,and the incentive effects on state-owned enterprises are more obvious.Third,the incentive effects of tax incentives on large and medium-sized enterprises are different,and the incentive effects on small and medium-sized enterprises are more obvious.Fourthly,the incentive effect of tax incentives on r?d investment of semiconductor enterprises has a lag.Combined with the current development characteristics of semiconductor enterprises in China and the existing shortcomings,put forward targeted suggestions:first,improve the innovation efficiency of state-owned enterprises and increase tax incentives for non-state-owned enterprises;Second,attach importance to r?d activities of large enterprises and improve preferential tax policies for small and medium-sized enterprises.Third,increase tax incentives for core technologies to encourage enterprises to overcome technical problems;Fourth,we will continue to implement preferential tax policies and improve the system of preferential tax policies.
