技术溢出、政府补贴对军工企业技术创新活动的影响研究——基于我国上市军工企业的实证分析

Research on Impact of Technology Spillovers and Government Subsidies upon Military Enterprise Technology Innovation Activities:An Empirical Analysis Based on China's Listed Military Enterprises

技术溢出与政府补贴是影响军工企业技术创新两大重要因素。通过对技术溢出和政府补贴影响企业技术创新活动的理论分析,以我国22家上市军工企业为样本,采用2009年-2012年面板数据模型,实证检验了技术溢出与政府补贴对于企业创新行为的影响,结果表明:技术溢出与军工上市企业研发产出显著负相关,其相关系数为0.67,说明技术溢出严重损害了军工企业创新研发动力,政府补贴与军工企业技术研发产出正相关,其相关系数为0.16,说明政府补贴能够促进军工企业技术创新研发,但作用并不十分显著,这一结果与军工企业的特性和行业发展规律相吻合。因此,军工企业应该通过技术创新产权激励机制等其他方式来减少创新溢出带来的企业创新动力的损害。

Technology spillovers and government subsidies are two key factors affecting military enterprise technology in-novation. Based on theoretical analysis of the various influence factors of enterprise technology innovation research and development, with 22 listed military enterprise in our country as samples, this paper used panel data model and empiri- cally test the technology spillovers and governent subsidies influence on enterprise innovation behavior. The results show that technology spillovers are significantly negative correlation with listed military industry enterprises R＆D production, the correlation coefficient is 0. 67. This manifest the technology spillovers damage listed military enterprise technology in-novation. Government subsidies are positive correlation with listed military enterprise technology innovation production,the correlation coefficient of 0. 16. This manifest government subsidies promote enterprise technology innovation research and development, but the effect is not very significant. The results and are consistent with the characteristics of military industry enterprises and law of military industry enterprises development. Military enterprise, therefore, should be through other ways such as technology innovation property right incentive mechanism to reduce spillovers damage to military en-terprise innovation power.
