资源依赖对区域创新的挤出效应及传导机制

在梳理资源依赖度、企业创新需求与区域创新绩效三者关系的基础上，提出相关研究假设，运用中国内地（除西藏外）30个省区2007-2015年的相关数据构建面板模型进行实证检验。结果表明：资源依赖对区域创新具有挤出效应；企业创新人才和技术需求对区域创新绩效具有正向影响。其中，企业创新人才需求的正向影响最显著；资源依赖对企业创新人才、资金和技术需求具有显著抑制作用。由此得出结论：资源依赖对企业创新需求的负向影响是其挤出区域创新的重要传递渠道。运用中介效应分析流程，分析了企业创新人才需求和资金需求在资源依赖挤出区域创新过程中的传导效应，计算了中介效应占总效应的比重及遮掩效应与直接效应的比例。建议通过制度创新激发企业内生创新需求，通过延伸产业链改变资源型产业的技术属性，强化企业对技术创新的有用性感知。

The Negative Impact of Resource Dependency on Regional Innovation Performance and Transmission Mechanism

Based on relevant literature, this paper explores the relationship of resource dependency, enterprises' innovation demand and regional innovation performance, and then put forwards a series of hypotheses. Using panel data of 30 provinces in China during 2007-2015, the empirical analysis examines the above hypotheses. The empirical results show that: The regional resource dependency has crowding-out effect on its innovation performance. The enterprises' demand for innovator and innovative technology have positive effect on the regional innovation performance. The regional resource dependency has significant negative effect on the enterprises' demand for innovator, innovative funds and technology. So that, the negative effect of resource dependency on enterprises' innovation demand is transmission channel in crowding-out effect of resource dependence on regional innovation. Then, this paper analyzes the nature of the transmission effect of the enterprises' demand for innovator and innovative technology, and calculates the ratio of shading effect to direct effect and the mediating effect in the total effect. Therefore, in resource-based regions, institutional innovation is the key to stimulate enterprises' endogenous demand for technology innovation. Moreover, the resource-based industry chains should be extended so as to change their technical attributes and strengthen their perception to usefulness of technological innovation.
