R&D投入、技术创新能力与企业经济绩效间关系的实证分析

Empirical Study on Relationship between R&D Input,Technological Innovation Capability and Economic Performance of Enterprise

以浙江省312家制造企业为研究对象,采用回归分析方法,对企业R&D投入、技术创新能力与经济绩效之间的关系进行了研究。结果表明:R&D投入与企业经济绩效显著正相关;新产品产出能力和发明专利申请量在R&D投入与企业经济绩效之间起部分中介作用,其中新产品产出能力的中介效应明显高于发明专利;尽管R&D投入对实用新型专利和外观设计专利的申请量有显著的促进作用,但这两类专利申请量并不是R&D投入与企业经济绩效间关系的中介变量。

Using the data about 312 manufacturing enterprises in Zhejiang province, this paper empirically studies the relationship between R＆D input, technological innovation capability and economic performance of enterprise by the method of regression analysis. The results show as follows：R＆D input is significantly positively correlated with economic performance new product output capacity and invention patent application play partial mediating roles in the relationship between R＆D input and enterprise＇s economic performance,and the mediating effect of new product output capacity is higher than that of invention patent application although R＆D input could promote the application of utility model patent and design patent significantly, these two types of patents have no mediating effects on the relationship between R＆Dinput and economic performance.
