知识溢出是解释技术进步、区域经济增长与收敛的重要因素。目前知识溢出与区域经济增长的相关研究主要集中在知识溢出影响经济增长的理论基础、知识溢出对经济增长的作用机理和知识溢出的经济效应与测度等。通过文献梳理,发现目前知识溢出的研究视角不够全面,对经济增长的作用机理分析不够清晰。因此,作者融合空间维度、产业维度和技术吸收维度,将知识溢出影响因素、溢出渠道、溢出类别、作用路径、溢出效应和效果等按逻辑关系串联起来,形成一个研究新框架。指出了未来的研究方向。
Knowledge spillover is a vital element explaining technical progresses and regional economic growth as well as convergence. Currently, researches on the relationship between knowledge spillover and regional economic growth mainly con- centrate on three respects. The first one is theoretical basis for knowledge spillover' s influences on economic growth. The second one is the mechanism of knowledge spillover' s functioning on economic growth. The last one is the econom- ic effects as well as measurement of knowledge spillover. However, the obscure analysis of mechanism of knowledge spillover' s functioning on economic growth and the imperfections of measurement means can be found in its literature review. On this basis, this paper fusions geospatial dimension, industrial structure dimension as well as technical absorption dimension, and the influence factors, spillover channels, spillover strength, spillover approaches, spillover benefits as well as economic effects of spillover will be linked according to logical relations, which will form a new framework for researches and point out the direction of future researches.
