Research On The Impact Of Government R＆D Subsidies On Enterprise Innovation Performance In New Energy Vehicle Industry

Human beings depend on natural resources to some extent in their lives.With the growth of population and the development of industrialization,the demand for natural resources in the world is constantly increasing,which has caused many environmental problems,such as haze,air pollution and global warming.New energy vehicles set energy saving,emission reduction,environmental protection and other characteristics in one,to a certain extent to alleviate the situation of environmental pollution and resource shortage,so the world began to focus on the development of new energy vehicles,China has followed.New energy vehicles can not only help China achieve energy structure transformation,but also promote economic growth.In the early stage of industrial development,there are often problems such as high price and immature technology,which make enterprises less profitable and unable to carry out technological innovation and maintain enterprise development for a long time.In this case,the company is not sustainable.Therefore,the government needs to support it and help the development of new energy vehicle enterprises.Now,the government will invest a lot of money to help new energy vehicles every year.The current situation of China’s new energy vehicle industry is: the development of research and development technology is still immature,innovation performance is low,the upstream and downstream industry chain is not sound,the technical strength level of new energy vehicles has not reached the psychological expectations of consumers,no scale effect.Enterprises should improve the level of innovation ability and innovation output to achieve high-quality development of the industry.While innovation activities need to invest a lot of money,government subsidies play an important role in this process,it can not only regulate the market,but also improve the enthusiasm of new energy vehicle enterprises.However,in the process of policy implementation,government subsidy policy has caused some negative effects,so it is particularly important to study the relationship between government subsidy and innovation performance of the new energy vehicle industry.In this paper,listed enterprises of the new energy vehicle industry chain from 2016 to 2020 are selected as research samples.Based on the industry chain perspective,the new energy vehicle industry chain is divided into upstream industry chain,midstream industry chain and downstream industry chain,and the following three issues are analyzed by establishing a regression model: The first is the relationship between government R＆D subsidy and enterprise innovation performance,the second is the relationship between government R＆D subsidy and R＆D input,and the third is whether there is a mediating effect of R＆D input on the relationship between R＆D subsidy and enterprise innovation performance.Based on the regression model test results,this paper draws the following conclusions :（1）R＆D subsidies of upstream and downstream firms can promote the improvement of firm innovation performance,and there is no significant correlation between R＆D subsidies of midstream firms and firm innovation performance.（2）Among upstream,midstream and downstream firms,increasing government R＆D subsidies can significantly increase R＆D investment.（3）In upstream and downstream firms,R＆D investment has a mediating effect on the relationship between R＆D subsidies and firm innovation performance.
