长三角地区科技创新与绿色发展耦合协调格局及驱动机制

Coupling and Coordination Pattern and Driving Mechanism of Scientific-Technological Innovation and Green Development in Yangtze River Delta Region

科技创新是绿色发展的根本动力,绿色发展引领科技创新方向和重点,厘清科技创新与绿色发展耦合协调规律及其驱动机制有助于实现区域创新与绿色发展一体化。基于2010~2020年长三角地区41个城市的面板数据,定量测算科技创新与绿色发展综合发展指数,并对两系统耦合协调的时空格局演变特征和驱动机制进行分析。研究结果表明:(1)长三角整体科技创新与绿色发展水平综合指数呈现缓慢递增的趋势,绿色发展水平普遍领先于科技创新水平。(2)长三角科技创新与绿色发展的耦合度和协调度整体上呈现良好的增长态势,协调城市数量由2010年的14个增长至2020年的35个,其中上海、苏州已进入优质协调阶段;空间上呈现“核心-边缘”特征,高值区集聚于“Z字型”轴线之上,低值区自东向西呈阶梯状递减。(3)各种因素综合影响两系统耦合协调度的大小,主要驱动力包括经济驱动力、社会促进力、市场推动力、外部竞争力和政府调控力。基于此,长三角地区应借力一体化发展战略,实施因地制宜的创新驱动发展举措,全面提升绿色科技创新能力。

Scientific and technological innovation is the fundamental driving force of green development.Clarifying the coupling coordination law of scientific and technological innovation and green development and the driving mechanism will help to realize the integration of regional innovation and green development.Based on the panel data of 41 cities in the Yangtze River Delta Region from 2010 to 2020,this paper quantitatively calculated the integrated development index of scientific and technological innovation and green development.The evolution characteristics and driving mechanism of the spatio-temporal pattern of the coupling and coordination of the two systems were analyzed.The results showed that:(1)The comprehensive index of scientific and technological innovation and green development level showed a slowly increasing trend.The green development level was generally ahead of the scientific and technological innovation level.(2)The coupling and coordination degree of the two systems showed s a growth trend on the whole.The number of coordinated cities increased from 14 in 2010 to 35 in 2020,among which Shanghai and Suzhou had entered the stage of high-quality coordination;Spatially,a"core-edge"feature was presented,with the high value area clustered on the"Z-shaped"axis,and the low value area decreased in a stepped pattern from east to west.(3)Various factors affected the degree of coupling coordination of the two systems.The main driving forces included economic driving force,social promoting force,market driving force,external competitiveness and government regulation.Based on this,there was a need for the Yangtze River Delta region to take advantage of the integrated development strategy,to implement innovation-driven development measures according to the local conditions,and to comprehensively enhance the green technology innovation capacity.
