政府研发补贴能否带动企业研发投入?——基于企业规模和属性的双视角异质性分析

Can government R&D subsidy stimulate enterprise R&D input?——Dual-perspective heterogeneity analysis based on enterprise size and ownership

通过构建政府研发补贴对企业研发投入作用的理论模型,运用动态面板方法,使用我国31个省级地区2009-2015年的数据,并按规模和所有制属性对企业进行分类,研究政府研发补贴能否带动企业研发投入.研究发现,研发补贴对中型企业、非国有企业和外资企业研发投入具有显著的带动作用,而对大型企业、国有企业研发投入则具有显著的抑制作用.通过分析高、中、低三种补贴率水平下的影响发现,国有企业存在严重的过度补贴问题,而非国有企业的研发补贴则相对不足,部分外资企业也存在过度补贴的问题.

By constructing the theoretical model of the effect of government R&D subsidy on enterprise R&D input,using the dynamic panel method and the data of Chinese 31 provincial regions during 2009-2015,this article studies if government R&D subsidy can stimulate enterprise R&D input according to the size and the ownership of enterprises.It is found that government R&D subsidy has significantly stimulated medium-sized enterprise,non-state-owned enterprise and foreign-capital enterprise input and inhibited large-sized enterprise and state-owned enterprise input.By analyzing the effect of high,medium and low subsidy rates,it is found that state-owned enterprises have serious over-subsidy problems,while non-state-owned enterprises have relatively insufficient R&D subsidy,and some foreign-funded enterprises also have over-subsidy problems.
