The Knowledge Flow of Industry-University-Research and the Development of Advanced Manufacturing in the Yangtze River Delta Urban Agglomeration:Mechanisms and Effects
Based on the two-stage value chain perspective,the knowledge flow of industry-university-research is divided into two stages:the stage of knowledge research and development and the stage of knowledge transformation.This study explores the impact mechanism of the knowledge flow efficiency of industry-university-research on the advanced manufacturing in the Yangtze River Delta urban agglomeration,and analyzes its spatial spillover effect.The results show that:1)From 2007 to 2020,the overall efficiency of knowledge flow showed a blocky agglomeration feature in the Yangtze River Delta urban agglomeration,and the development level of advanced manufacturing gradually increased from the northwest to the southeast.The absolute differences in the knowledge research and development efficiency and the knowledge transformation efficiency among cities showed an increasing and decreasing trend respectively,while the absolute differences in advanced manufacturing gradually decreased.2)The impact of knowledge flow efficiency on advanced manufacturing was significantly positive,and the promotion of knowledge transformation efficiency on advanced manufacturing was greater than that of knowledge research and development efficiency.3)The efficiency of knowledge flow can promote the development of advanced manufacturing by promoting urban industrial upgrading and technological diffusion,but there are differences in the mechanism of this effect.4)The efficiency of knowledge research and development and the efficiency of knowledge transformation have a significant positive spatial spillover effect,which has a promoting effect on the advanced manufacturing industry in the local and neighboring regions.
