摘要：基于区域创新生态系统(RIE)视角,以长三角中心区27城为研究对象,深入剖析长三角区域创新一体化协同发展趋势、溢出效应及影响因素。结果表明:长三角RIE生态位适宜度的中高值区域呈现出由沿海向内陆发散的空间集聚特征,以及围绕G60科创走廊中心区的“西北—东南”空间分布特征,形成“雁阵”空间形态;长三角RIE存在创新空间关联性,且空间正相关性逐年增强,协同发展的空间溢出效应显著。其中,人力资本、金融发展和双碳约束的影响力较大,且规上研究与试验发展经费投入存在显著的直接效应和空间溢出效应。为进一步打造长三角科技创新共同体,政府应加大中心区27城规上研发经费投入,充分发挥中心区对其它地区的辐射和引领作用。
The Chinese government affirms that innovation has become the primary driving force and collaboration is an endogenous feature.At present,the high-quality integration of the Yangtze River Delta has been accelerated.It is urgent to promote greater openness and sharing through collaborative innovation to form the positive circle of a large domestic unified market.On this premise,the free,orderly,safe and convenient flow of essential factors would be promoted across borders and regions,the domestic and international markets would be promoted in better connectivity,and a collaborative model of mutual promotion of domestic and international dual circulation could be formed.A beneficial exploration of RIE collaborative development and its spillover effects in the Yangtze River Delta has been made in the existing research.However resource acquisition and utilization ability,the relationship competition and cooperation in RIE are ignored,which makes it unable to systematically explain the disequilibrium development in RIE;the existing research is inadequate in the visual analysis methods to present the collaborative development trend of regional sci-tech innovation,that is,space extension,gradient layout and dislocation development in the Yangtze River Delta RIE;the panel data of 27 cities in the central area of the Yangtze River Delta(abbrev.as 27 cities)is not mentioned,and the spillover effect of RIE collaborative development and its influencing factors in the development process of Yangtze River Delta community of sci-tech innovation are not explored.Thus,from the perspective of RIE,this study takes 27 cities in the central area of the Yangtze River Delta as the research objects,and analyzes the trend of regional innovation integration and collaborative development,spillover effect and its influencing factors of RIE in the Yangtze River Delta.Firstly,it conducts a principal component analysis on the components of RIE.Secondly,with the scientific,comprehensive and data availability principles,the ecological niche evaluation index system of RIE collaborative development in the Yangtze River Delta under the dual circulation pattern is built from the perspective of the joint action of innovation community and environmental community.Thirdly,the niche model and fixed effect model of SDM are constructed.With the relevant statistical data of collaborative innovation in the Yangtze River Delta region during 2012-2020,visualization methods are used to deeply analyze niche width,suitability,momentum and overlap.Furthermore,the overall trend,regional differences and spatial agglomeration of the collaborative sci-tech development,and its spillover effect and influencing factors in the 27-city region are comprehensively analyzed to improve the development level of the Yangtze River Delta urban agglomeration during the"14th Five-Year Plan",and promote the collaborative and common progress of the Yangtze River Delta community of sci-tech innovation.The medium and high-value areas of RIE niche suitability in the Yangtze River Delta present the trend of spatial agglomeration diverging from coastal to inland areas,with the spatial distribution characteristics of"northwest-southeast"around the central area of the G60 S&T innovation valley to form a spatial pattern of"geese array".There is an innovation spatial correlation of RIE in the Yangtze River Delta.The positive spatial correlation has been increasing year by year and the spatial spillover effect of collaborative development is significant.Moreover,the human capital,financial development and constraints of carbon peaking and carbon neutrality goals bring great impact on the spatial spillover effect.There are significant direct effects and spatial spillover effects of R&D investment for industrial enterprises above designated size.In order to successfully build the Yangtze River Delta community of sci-tech innovation,the government should promote R&D investment of industrial enterprises above designated size in the 27 cities of central China so that they can play an important role in the spin-off effect and demonstration to other areas.This paper provides empirical support for the further policy promotion of regional community of sci-tech innovation and the collaborative development of sci-tech innovation in urban agglomeration.
