长三角区域创新绩效的价值链模型分析

Study of the Yangtze River Delta Regional Innovation Performance Based on Innovation Value Chain

通过构建创新价值链分析框架,采用2003—2014年的面板数据,将长三角区域的研发创新分为知识创新环节和产品创新环节来进行研究,借此说明长三角区域创新价值链的两个环节创新产出的经济特征。研究表明:在知识创新环节,各省市的专利授权增长率呈逐年递增的趋势,其产出成绩良好;在产品创新环节,产品创新绩效总体较低,上海的产品创新绩效逐年递增,而江苏省、浙江省与安徽省的产品创新绩效却增长缓慢。同时,对创新价值链的内在动因进行深入研究,进而为区域经济发展提出相关政策建议。

This paper applies the panel data from 2003 to 2014 to analyze the Yangtze River Delta region through the way of constructing a frame of innovation value chain,this region’s innovation contains two aspects according to this paper,knowledge innovation and product innovation,so that explaining the economic features of the two aspects’innovation output of the region’s innovation value chain.The research shows that in the aspect of knowledge innovation,the growth rate of patent grant in each province is increasing yearly.But in the aspect of product innovation,the overall innovation performance is unsatisfying,the product innovation performance in Shanghai increases gradually,but not very well in Jiangsu,Zhejiang,and Anhui Province.This paper studies in depth the internal impetus of the innovation value chain and puts forward relevant political suggestions for the regional economy development.
