摘要
基于中国工业企业数据库1998-2007年的数据,对政府补贴与企业创新之间的关系进行研究。研究发现:政府补贴与企业创新之间均存在显著的倒U型关系,政府补贴可以激励企业选择创新并提高其创新产出和创新绩效,但当政府补贴达到一定水平时,就会抑制这种对企业创新的影响。机制分析表明:适度的政府补贴能够补充并提高企业所需的研发投入,进而促进企业创新水平的提高,研发投入提升是政府补贴影响企业创新的重要机制。此外,政府补贴对企业创新的影响存在企业异质性。相比国有企业,政府补贴对民营企业创新产出的影响更为明显;相比于大规模企业,小规模企业创新产出对政府补贴的敏感度更高;在区域差异上,政府补贴对东部企业存在正向影响,而与中西部企业创新之间存在显著倒U型关系。
Based on data from the China Industrial Enterprise Database from 1998 to 2007, this paper studies the relationship between government subsidies and enterprise innovation. The study found that there is a significant inverse U-shaped relationship between government subsidies and enterprise innovation. Government subsidies can encourage enterprises to choose innovation and improve their innovation output and innovation performance, but when government subsidies reach a certain level, which will inhibit this effect on enterprise innovation. The analysis of the mechanism shows that moderate government subsidies can supplement and increase the R&D investment required by enterprise, thereby promoting the improvement of enterprise innovation level. R&D investment promotion is important mechanism for government subsidies to affect enterprise innovation. In addition, the impact of government subsidies on enterprise innovation is heterogeneous.Compared with state-owned enterprises,the impact of government subsidies on the innovation output of private enterprises is more obvious. Compared with large-scale enterprises, the innovation output of small-scale enterprises is more sensitive to government subsidies. In terms of regional differences,government subsidies have a positive impact on east enterprises,and there is a significant inverted U-shape relationship with middle and west enterprises.
