Research On The Impact Of Fiscal And Taxation Policies On R&D Investment Of New Energy Vehicle Enterprises

In recent years,with the development trend of low-carbon economy,new energy vehicles have emerged.From the generation to the promotion of new energy vehicles,the state has continuously introduced a number of more systematic and comprehensive fiscal and tax policies to support its development.The most important way is to promote the marketization of new energy vehicles through government subsidies and preferential tax policies.The key to the current development of new energy vehicle companies is technological innovation.However,R&D investment determines technological innovation capabilities.Therefore,it is of great significance to research the R&D investment of new energy vehicle enterprises.In China,most of the related researches are theoretical analysis and macro data research,but there are few researches on the analysis of the combination of government subsidies and preferential tax policies for new energy vehicles companies studied in this paper.This paper selects the data of listed companies of new energy vehicles,using a combination of theoretical and empirical analysis to specifically analyze and compare the impact of government subsidies and tax incentives on the research and development investment of new energy vehicle companies.This article collects 2012-2018 data of 83 listed new energy automobile companies to establish a panel data model.Then it uses a fixed-effects model to regress the data and performs a robustness test.It analyzes the impact of fiscal and taxation policies on R&D investment of new energy vehicle enterprises.The results show that:(1)the government subsidy and the income tax discount can effectively promote the research and development investment of new energy vehicle enterprises;(2)The preferential turnover tax has little effect on the promotion of R&D investment of new energy vehicle companies;(3)The incentive effect of government subsidies and income tax incentives on the research and development investment of non-state new energy vehicle companies is greater than that of state-owned enterprises;The R&D investment of new energy vehicle companies in non-eastern region has a significant role in promoting.However,the incentive effect of preferential income tax on R&D investment of new energy vehicle companies in the eastern region is greater than that in non-eastern regions.According to the results of analysis,based on the experience of other countries,the paper throws out the following suggestions:(1)optimizing the government subsidy mechanism;(2)improving the government subsidy supervision system;(3)strengthening the core technology Subsidies;(4)enlarging the scope of preferential turnover tax and increasing income tax preferential.
