摘要/Abstract

摘要： 知识溢出高度依赖于地理邻近性，知识溢出效应的高低决定了区域经济发展的地区差异。基于Griliches-Jaffe知识生产函数，选用研发支出、人力资本、专利水平三种知识存量替代变量，借助SEM空间误差模型实证测度和分析知识溢出效应及其对区域经济增长的影响。研究表明，三种知识存量变量具有显著的知识空间溢出效应，Jacbos效应、Porter效应对我国区域经济增长有很强的正向影响。各地区，特别是欠发达地区应充分发挥知识溢出效应，提高城市集聚度、地区人力资本存量，加大研发经费支出，以增强知识溢出效应对区域经济增长的促进作用。

Abstract: Knowledge spillovers are highly dependent on geographical proximity. the level of knowledge spillover determines the disparity of regional economic development. we empirically measure and analyze the knowledge spillover effect and its impact on regional economic growth based on Griliches-Jaffe Knowledge production function that includes three kinds of knowledge stock substitution variables of R & D expenditure, human capital and patent level by SEM model. The research shows that three knowledge stock variables have significant knowledge spillover effects. the Jacbos Porter effect has a strong positive impact on China's regional economic growth. Therefore, it is suggested that knowledge spillovers should be brought into full play in all regions, especially in less developed areas. we should improve urban agglomeration degree, regional human capital stock and increase R &D expenditure to enhance the role of knowledge spillover effect on regional economic growth.

Key words: knowledge spillover, spatial effect, regional economic, SEM model
