摘要 区域经济一体化深入推进,要素流动突破地理“邻近”限制,要素耦合提升不仅取决于自身属性,亦取决于空间关联效应。采用耦合协调度模型,测度我国省域创新链产业链资金链人才链(简称“四链”)耦合协调度水平;基于测度结果运用社会网络分析(SNA)方法,考察省域“四链”耦合空间关联网络结构特征;运用二次指派程序(QAP)探究省域“四链”耦合的影响因素。结果表明:2016-2021年我国省域“四链”耦合协调度呈稳步提升态势,但总体仍处于较低水平,呈“东高西低”非均衡分布特征。整体网络特征方面,“四链”耦合协调空间网络紧密度呈波动上升态势,总体仍有较大提升空间;上海、江苏、北京等地区处于核心位置,而海南、宁夏、新疆等地区处于边缘位置,“核心–边缘”结构特征明显。科技创新投入强度、经济水平和教育投入强度对省域“四链”耦合空间关联有显著影响,建议树立联动意识,弱化距离等因素制约,促进区域间资源要素流动;制定差别化的区域发展政策,优化空间网络结构,缩小区域间差距,进一步推进“四链”深度耦合协调发展。 Regional economic integration continues to advance deeply,with the flow of factors breaking through the geographical“neighbourly”restrictions.The enhancement of factor coupling depends not only on their own attributes but also on spatial association effects.The coupling coordination model was adopted to measure the level of coupling coordination among the innovation chain,industrial chain,capital chain,and talent chain(referred to as“four chains”)within provincial regions in our country.Based on the measurement results,the social network analysis(SNA)method was employed to investigate the structural characteristics of the spatial association network of the“four chains”across provincial regions.The quadratic assignment procedure(QAP)was employed to explore influencing factors of the coupling among the“four chains”in provincial regions.The results show that from 2016 to 2021,the coupling coordination of“four chains”in provincial regions of our country has been steadily increasing,but the overall it still remains at a low level,exhibiting an uneven distribution characteristic of“high in the east,low in the west”.In terms of overall network characteristics,the tightness of the“four chains”coupling coordination space network shows a fluctuating upward trend,but there is still significant room for improvement in the whole.Shanghai,Jiangsu,Beijing and other regions are in the core position,while Hainan,Ningxia,Xinjiang and other regions are in the marginal position,and the“core–edge”structure characteristics are obvious.The intensity of scientific and technological innovation investment,economic level,and the intensity of education investment have a significant impact on the“four chains”coupling spatial correlation in province regions.It is recommended to establish linkage awareness,mitigate constraints such as distance,and promote the flow of resources and factors between regions,formulate differentiated regional development policies,optimize the spatial network structure,narrow the interregional gaps,and further promote the deep coupling and coordinated development of the“four chains”.
