The Research On The Effect Of Government R&D Investment On Enterprise Innovation Output

Improving the investment mechanism with government investment as the mainstay and social multi-channel investment as the supplement is an important part of improving our country’s scientific and technological innovation system.However,whether the government R&D investment-based model effectively stimulates enterprise innovation and then promotes the implementation of innovation-driven development strategies,the conclusions of existing studies are still controversial.Using the 2003-2013 China patent database and China industrial enterprise database,combined with the main business scope of industrial enterprises,this article first matches the patents related to each industrial enterprise and the main business,and then organizes the enterprise-level data into prefecture-level city level,and analyze the effects of government and non-government funds in the R&D investment of each city on the growth of corporate patents.The results show that:First,government R&D investment can help improve the growth of enterprise patents,but its role in enhancing the quality of corporate patents needs to be improved.Second,the investment from non-government funds in R&D investment has a better effect on related patents than non-related patents.Taking into account that non-government funds are mainly derived from enterprises’ own funds,this indicates that guiding enterprises to independently increase R&D investment will be more helpful to promote the growth of higher-quality patents.Third,the incentive effect of government R&D investment on the growth of enterprise patents is heterogeneous.In the central and western regions,cities with a higher state-owned economy and a higher level of industrialization,the role of government R&D investment will be stronger.Fourth,from the perspective of influencing factors,patent agencies help to enhance the positive effect of government R&D investment on the two types of patents,especially the growth of non-related patents.Based on this,the research conclusions of this article reveal that:First of all,the current government R&D investment is more likely to expand the extension of corporate patent growth,causing companies to increase a large number of patents that have nothing to do with their main business.This may be one of the reasons that caused the "chaos" and "junk patents" to prevail in our country’s patent market in recent years;Secondly,changing "government subsidies" to "tax reduction and exemption" in order to increase enterprises’ independent R&D investment will be more conducive to increasing enterprises’ patent output.Thirdly,we must pay attention to the weakening effect of the state-owned economy on the use of government R&D investment funds,avoid state-owned enterprises "patents for subsidies",and therefore create a large number of patents that are not related to the main business.Finally,it is necessary to further correctly understand the intermediary role of patent agencies in order to promote the increasing of the number of patents related to enterprise main business,and to improve the efficiency of government funds for research and development.
