Environmental pollution and energy shortage are two major crises currently facing the world.In order to avoid the negative impact of the crisis,maintain my country’s ecological security,and achieve sustainable economic development,the central government put forward the strategic concept of "green development",while promoting traditional automobiles.The transformation and upgrading of enterprises and the vigorous development of new energy power vehicle enterprises are an important part of it and the main direction of the future development of the automobile industry.As an emerging enterprise,the R&D activities of new energy vehicle enterprises have the characteristics of long cycle and high risk.In order to improve the competitiveness of my country’s new energy vehicle enterprises,my country has introduced many fiscal and tax policies to encourage them to carry out technological innovation.Among them,the additional deduction policy for research and development expenses is considered to be one of the most widely used and important tax incentives for the government to encourage independent innovation.Based on this,this paper takes the super-deduction policy implemented on January 1,2016 as an exogenous policy.Starting from an empirical analysis,it attempts to study three issues: first,to analyze the impact of the super-deduction policy on the R&D activities of new energy vehicle companies;To study whether the policy plays a positive or negative role in the process of enterprise R&D investment and innovation output;secondly,to study the difference in the role of the super deduction policy for different types of enterprises;thirdly,to explore whether R&D investment has played an intermediary role.effect,that is,the mechanism of action of the super-deduction tax policy.This paper first summarizes the relevant literature results of domestic and foreign scholars on the effect of preferential tax policies on enterprise technological innovation,and then introduces the development status and institutional background of technological innovation in the new energy vehicle industry,and provides relevant provisions on my country’s super deduction policy and enterprises.The concept of innovation is expounded,and then related theories are sorted out,the mechanism and effect of the R&D expense deduction policy are analyzed,and the policy application of new energy vehicle enterprises is explained.Then,combined with the annual report data of more than 200 listed companies in the new energy vehicle industry from 2016 to 2020,an empirical analysis was made on the impact of the tax deduction policy on the R&D investment and innovation output of enterprises.Heterogeneous regression of degree and market competition degree.At the same time,the mediation effect test for R&D investment was carried out.The research conclusions of this paper are as follows: first,the tax deduction policy can obviously promote the new energy vehicle enterprises to improve the level of technological innovation.Within new energy vehicles,the super deduction policy has a stronger incentive effect on technological innovation in high technology-intensive industries;third,the level of market competition affects the effectiveness of the super deduction policy.In terms of R&D investment,companies with a high degree of market competition are more likely to be influenced by policies and increase R&D investment.In terms of innovation output,companies with lower levels of competition are more likely to be influenced by policies to increase R&D output;fourth,the impact of the tax policy on enterprise innovation output is realized through R&D investment,which is fully intermediary effect.Finally,based on the above empirical analysis,this paper puts forward the following suggestions: first,to further enhance the preferential treatment for high-tech-intensive enterprises,second,to implement differentiated additional deduction tax policies,third,to improve the incentive policies for enterprises with different market competition levels,and fourth,to improve incentive policies for enterprises with different market competition levels. |
