摘要
在创新资源全球流动加速的背景下,海外研发投资已成为中国企业提升自主创新能力的重要战略。本文基于2009—2018年沪深六个制造业行业上市公司的数据,运用倾向得分匹配—双重差分模型(PSM-DID),实证研究了海外研发投资对中国企业创新绩效的影响及其内在机制。研究结果表明:海外研发投资能显著促进企业创新绩效的提升,此影响具有逐年递增的动态效应;知识基础扩增与研发效率提升是海外研发投资影响企业创新绩效的两个重要机制;从海外研发投资动机、股权性质与是否隶属于企业集团三个视角进行企业异质性分析,结果显示,探索学习型、非国有企业与隶属于集团的企业海外研发投资对创新绩效的促进作用更为显著。
In the context of accelerating global flow of innovation resources,overseas R&D investment has become an important strategy for Chinese enterprises to enhance their self-reliance and innovation capabilities.Based on the data of six kinds of manufacturing companies listed in Shanghai and Shenzhen from 2009 to 2018,this paper used PSM-DID model to empirically explore the impact of overseas R&D investment on Chinese enterprises innovation and its internal mechanism.It is found that overseas R&D investment can significantly promote the innovation performance of enterprises,and this effect has a dynamic effect of increasing year by year.It also verifies that knowledge base and R&D efficiency are two important mechanisms that overseas R&D investment affects enterprise innovation performance.The analysis of enterprise heterogeneity shows that the overseas R&D investment of exploration learning,non-state-owned enterprises and enterprises affiliated to the group have played more significant role in promoting innovation performance.
