政府补贴促进了企业专利质量提升吗?

Does Chinese government subsidies promote the quality of enterprise patents?

中国经济正处于由要素推动型模式向创新驱动模式转变的历史时期，政府补贴已成为激励企业创新研发、加快经济发展方式转型的主要推手。本文以此为背景，借助匹配模型和企业专利数据就中国政府补贴对企业专利质量的总体影响效果、影响的滞后性、持续性等问题进行了实证研究。检验发现，政府补贴对企业专利质量的提升具有促进作用，同时这种促进作用具有一定的滞后性和持续性。在分样本检验中发现，政府补贴的促进作用与被资助企业的所有制属性、企业规模以及知识产权保护的力度密切相关。这些实证结果为中国未来创新资助政策的调整提供了有意义的参考。

China is in a historical period of economic development and the transformation from the factor driven model to the innovation driven model, Government subsidies have become the main driving force to encourage enterprises to develop innovative and accelerate the transformation of economic development mode. Based on this background, this paper makes an empirical study on the impact of Chinese government subsidies on the overall impact of the patent quality of enterprises, the lag of the impact of the matching model and the enterprise patent data. PSM - DID model based on the inspection found that the government subsidies for enterprises enhanced the quality of patent promotion, while the role of this promotion has a certain lag and continuity. In the sub sample test, the role of govern- ment subsidies is closely related to the property of the funded enterprises, the scale of the enterprises and the protection of intellectual property rights. These empirical results provide a meaningful reference for the adjustment of Chinese innovative funding policy in the fu- ture.
