长三角区域知识溢出研究

Study on Regional Knowledge Spillover in Yangtze River Delta

目前对知识溢出的研究较多的集中于个体(即企业)角度,本文将研究视角转向空间。借鉴经典的知识溢出空间模型,根据知识的分类,利用结构方程模型(SEM)对知识存量及溢出形式进行拟合,并以上海为中心,测度长三角区域内的知识溢出情况,溢出结果用蜂窝图显示。实证结果表明:上海对长三角区域的知识溢出辐射影响尚且不足,由于空间距离、知识差距与吸收能力等因素的影响,江浙两省各市在知识溢出和吸收方面有所差别。长三角区域知识溢出的分析有助于政府从新的角度采取措施,营造利于区域经济共同发展的环境。

The traditional observation unit on knowledge spillover is individual（namely firm）,while this is turned to space in this paper.Based on the previous spatial knowledge spillover model,the research obtains the linear fitting of the knowledge stock and its spillover routes with the method of SEM（Structural Equation Modeling） according to the classification of knowledge.Then the research makes Shanghai as the center to analyse the process of knowledge spillover in the Yangtze River Delta and the result is shown by beehive diagram.The empirical analysis shows that Shanghai＇s spillover effect on other cities is not well enough.Some factors,such as space distance,knowledge gap and absorptive capability,result in the difference between Jiangsu and Zhejiang on knowledge spillover.The analysis of regional knowledge spillover in the Yangtze River Delta is helpful to government to take new measure to ameliorate the environment in favor of common development.
