摘要: 在系统梳理双向投资协调效应影响企业创新质量理论机制的基础上,利用匹配后的中国创新型企业与专利数据库,通过中介效应模型和面板工具变量法,从专利异质性视角实证检验了双向投资对我国创新型企业创新质量的影响效应。研究发现,双向投资总体上有利于提高创新型企业创新质量,且对于发明专利表现较为明显。进一步的研究结果发现,双向投资通过研发资金和研发人员投入的中介机制有利于提升发明专利和外观设计专利的质量,双向投资可以提高高融资约束和非国有企业的创新质量,而对外直接投资则促进了低融资约束、国有和中西部地区企业的创新质量。

Abstract: Theoretical mechanism of the two-way investment coordination effect affecting the enterprises patent quality is systematically clarified first Then using the matched database, and through the mediating effect model and panel instrument variable method, the effect of two-way investment on the patent quality of innovative enterprises in China is empirically examined from the perspective of patent heterogeneity It is found that: two-way investment is generally beneficial to improving the patent quality of innovative enterprises, and the regression of invention patent is more significant Further, two-way investment helps to improve the quality invention patent and design patent through the mediating effect mechanism of R&D fund input and R&D personnel input Finally, from the heterogeneity analysis, two-way investment can improve the patent quality of enterprises with high financing constraints and non-state-owned enterprises, while foreign direct investment promotes the patent quality of enterprises with low financing constraints, state-owned enterprises and central and western enterprises

Key words: patent heterogeneity, two-way investment, innovative enterprise, innovative quality
