政府研发资助、企业研发投入与创新绩效之间的动态交互效应

Research on the interaction effects among government R D funding, enterprise R D inputs and innovation performance

摘要:

选取2009-2017年我国省级面板数据,利用PVAR模型分析政府研发资助、企业研发投入与创新绩效之间的动态交互作用,以及各地区之间的差异。结果表明政府研发资助和企业研发投入均对创新绩效具有促进作用,且创新绩效对企业研发投入的响应更迅速,但对政府研发资助的响应程度更大。创新绩效对政府研发资助具有抑制作用,而其对企业研发投入具有促进作用。政府研发资助与企业研发投入之间的关系则是先相互促进后相互抑制。体现了政府研发资助与企业研发投入之间的复杂关系,“杠杆效应”与“挤出效应”先后发挥主导作用。各地区之间具有区域异质效应。全国、东部、中部和西部在响应方向、响应速度方面均具有区域差异性。

Abstract:

This paper analyzes the dynamic relationship among government R D funding, enterprise R D inputs and innovation performance and the difference between regions of China using PVAR model based on the panel data of China from 2009-2017.The results show that both government R D funding and enterprise R D inputs have a positive effect on innovation performance, and innovation performance is more quickly responsive to enterprise R D inputs, but more violently responsive to government R D funding. Innovation performance has a depressing effect on government R D funding, and it has a positive effect on enterprise R D inputs. The relationship between government R D funding and enterprise R D inputs is first mutually reinforcing and then mutually inhibiting each other. It reflects the complex relationship between government R D funding and enterprise R D inputs. The “lever effect” and “crowding-out effect” have played a leading role in sequence. There are regional heterogeneous effects between regions. The national, eastern, central, and western regions have regional differences in response directions and response speeds.
