Research On Government R&D Funding,Enterprise Heterogeneity And Innovation Efficiency

With the increasingly fierce international competition,national economic development depends on innovation,and innovation has become the focus of attention of various departments in China.At present,the development of scientific and technological innovation is slow.In addition,the achievements of scientific and technological innovation itself are contingent and "quasi-public goods".Therefore,enterprises are not enthusiastic about technological innovation.The science and technology innovation activities supported by high-level investment have already appeared the phenomenon of "market failure".The government has issued corresponding policies to correct the market failure phenomenon.It has become the first choice of countries.It is controversial whether the government R & D funding can promote China's innovation level.It has become a hot issue for scholars from all walks of life.Overview of relevant research at home and abroad,there are different opinions on the relationship between government R & D funding and innovation efficiency.This paper uses stochastic frontier analysis(SFA)to conduct an empirical analysis of panel data of China's strategic emerging industries from 2014 to 2018.The sample explores from a holistic perspective,and then explores from different perspectives on different ownership properties,different core competitiveness,different growth stages,and different regions to examine the specific impact of government R & D funding on innovation efficiency.The study found that government R & D funding has a significant positive impact on promoting the technological innovation efficiency of all sample enterprises,and has a differential impact on the technological innovation efficiency of heterogeneous enterprises.Specific manifestations are: from the perspective of different ownership properties,government R & D funding is conducive to the improvement of non-stateowned enterprises' innovation efficiency.This conclusion is consistent with the overall sample conclusion;the coefficient of influence on the technological innovation efficiency of state-owned enterprises is not significant.From different cores,government R & D funding has a significant positive effect on enterprises with or without core competitiveness.However,the effect on enterprises with core competitiveness is even more pronounced.From the point of view,for enterprises with a establishment time of less than 15 years,15-20 years,and 20-25 years,government R & D funding is conducive to the improvement of the technological innovation efficiency of these enterprises,but it has no impact on enterprises more than 25 years old.Significantly,from the perspective of different regions,for enterprises in the eastern and central regions,government R & D funding has a significant positive impact on the technological innovation efficiency of enterprises in these regions.For enterprises in the western region,government research funding has not had a significant effect on their innovation efficiency.The research in this article enriches and improves existing research,and provides a reference for the government to formulate a series of specific technological innovation incentive policies.
