创新型城市内部企业R&D模式与创新绩效研究

R&D mode and innovation performance of enterprises within innovative cities

提高企业创新绩效是建设创新型城市的有效途径,而R&D模式与企业创新绩效密切相关。利用创新型城市规模以上工业企业R&D数据,基于改进的知识生产函数,对创新型城市内部企业不同R&D模式的创新产出进行计量分析。结果显示,内部研发的产出弹性远高于R&D合作的产出弹性,并且无论对知识型还是经济型产出都呈现稳健性;不同的R&D合作模式的创新绩效也存在差异。相关分析表明,企业研发实力、城市研发资源和教育资源的丰富程度、企业集聚度和国际化程度,以及政府的支持力度影响企业对R&D模式的选择。

Improving enterprise innovation performance is an effective way to build innovative city, and R＆D mode is closely re- lated to the enterprise innovation performance. By employing the R＆D data of industrial enterprises above designated size within innovative cities, an econometric analysis of innovative output of enterprises＇ different R＆D mode is made based on improved knowledge production function. Results indicate that the output elasticity of internal R＆D is much higher than that of R＆D cooper- ation, and both knowledge - based output and economic output of internal R＆D are showing stability; different R＆D cooperation mode has different innovation performance. Correlation analysis indicates that R＆D mode selection is affected by the enterprise R＆D capability, richness of urban R＆D and educational resources, degree of enterprises agglomeration and internationalization, and government support for R＆D activities.
