| Innovation is the primary productive force leading the development of the country,and it is also an inexhaustible driving force for the long-term development of enterprises.Nowadays,international competition is becoming increasingly fierce,countries are in urgent need of developing emerging technologies to seize development opportunities,if China wants to maintain a dominant position in international competition,it must continue to enhance independent research and development and innovation capabilities,solve the key technology "stuck neck" dilemma,and grasp the lifeblood of future economic development in their own hands.As an important carrier of national R&D and innovation,the independent innovation ability of enterprises is crucial to the long-term development of China’s science and technology and even the overall economy.However,as an inherent attribute of R&D and innovation activities,technology spillover is very easy to cause market failure,and its high cost,high risk and long cycle also aggravate the uncertainty of enterprise R&D,resulting in the low enthusiasm of enterprises to carry out R&D and innovation.Therefore,how to effectively encourage enterprises to expand R&D investment and fully mobilize their enthusiasm for R&D and innovation has gradually become the focus of governments in formulating and implementing innovation policies.Among them,the identification of high-tech enterprises,tax incentives and innovation funding policies have attracted much attention because of their commonness and wide application,and the analysis of the impact of the three on enterprise R&D investment has gradually become a hot topic in the academic circles.Therefore,in the introduction and theoretical analysis part,this paper first sorts out and summarizes the relevant literature at home and abroad,then briefly introduces the basic theoretical basis involved in this paper,and basically defines some important concepts,and finally discusses and analyzes the impact mechanism of high-tech enterprise identification,tax incentives and innovation funding on enterprise R&D investment from four perspectives.In the analysis of the current situation,this paper first collates and counts the relevant data of China’s high-tech enterprises and R&D investment from 2008 to 2020,and then visually analyzes them,and finds that although the social atmosphere of R&D and innovation in China is strong,it still needs to be strengthened in terms of the intensity of R&D investment and the development quality of high-tech enterprises.In the empirical research part,this paper selects the relevant data of China’s A-share listed companies from 2011 to 2021,and uses a variety of measurement methods to study and analyze the impact of the three policies of high-tech enterprise identification,tax incentives and innovation funding on enterprises’ R&D investment.In the conclusion and recommendation section,based on the empirical research results above,this paper concludes that the enterprise is identified as a high-tech enterprise with a positive incentive effect on its R&D investment,and the identification of high-tech enterprises significantly enhances the incentive effect of tax incentives and innovation funding on enterprise R&D investment.In addition,individual policies such as tax incentives and innovation funding can positively stimulate R&D investment of enterprises,but the two do not have significant complementary effects.Finally,based on the above research conclusions,this paper puts forward feasible suggestions on further improving the existing innovation policy system in China,hoping to provide useful reference for it. |
