摘要
基于2003—2018年企业股权关联投资数据,融合社会网络分析、马尔可夫链分析和空间计量方法,从全球、全国和区域尺度探析长三角地区城市投资联系水平的时空动态特征及影响因素。研究发现:①长三角地区各尺度的城际投资规模大幅提升,与关境外地区、关境内地区和长三角区域内的投资联系分别呈现服务业驱动型、制造业驱动型和行业均衡型特征。②各尺度城市投资网络呈现区域指向性和多中心演化特征,上海、杭州、南京等在长三角地区逐渐发挥对外辐合全球和全国投资、对长三角地区内部辐射区域的作用。③与关境外、关境内和区域内的城市投资联系水平空间分布不均,以沪宁合杭甬发展廊道为支撑的空间结构逐渐凸显,并分别呈现低水平区集中连片分布、改善空间先沿海后内陆扩张、中低水平区广域化扩张的突出特征。④城市投资联系水平整体呈现向邻近较高水平方向转移态势,很难实现跨越式转移,存在显著的俱乐部趋同效应和马太效应。随着空间尺度的扩大,向较高水平方向转移的难度随之增大,俱乐部趋同效应和马太效应也随之增强。地理空间格局在各尺度的城市投资联系水平状态转移中发挥着重要作用,发展水平较高和较低的城市对周边城市分别产生正向和负向的空间溢出效应。⑤产业基础、劳动力成本、城市行政级别对各尺度的城市投资联系水平均有显著影响,创新能力对各尺度的城市投资联系水平均未产生显著影响,时间距离对全球和全国尺度的城市投资联系水平影响显著,经济全球化仅对全球尺度的城市投资联系水平产生显著影响。
Based on corporate equity connection investment data among cities during 2003-2018,this study investigates the urban investment linkage level in the Yangtze River Delta(YRD),aiming to explore spatio-temporal dynamics of urban investment linkage level in this region at global(outside the Chinese customs territory),national(within the Chinese customs territory),and regional scales by the social network analysis and Markov chain methods.The spatial panel data econometric model further reveals the factors of urban investment linkage level.The results of the study are as follows:(1)The amount of intercity investment in the YRD has dramatically increased,and the industry structure of investment at the global,national,and regional scales are characterized by service-driven,manufacturing-driven,and industry-equilibrium types,respectively.(2)The urban investment network shows the characteristics of regional orientation and polycentric evolution.Cities such as Shanghai,Hangzhou and Nanjing are playing an increasingly important role of converging the global and national investment,and radiating the region internally in the YRD.(3)The spatial distribution of urban investment linkages is uneven at global,national and regional scales,showing that the spatial structure supported by the Shanghai-Nanjing-Hefei-Hangzhou-Ningbo development corridor is gradually highlighted.The global,national,and regional levels of urban investment linkage present the outstanding characteristics of continuous distribution of low-level areas,first coastal and then inland expansion of improved spaces,and wide-area expansion of medium-and low-level areas.(4)The urban investment linkage level tends to shift to the adjacent higher level,and it is difficult to realize the leap forward transfer.There are significant club convergence effects and Matthew effects.With the expansion of spatial scale,the difficulty of transferring to a higher level will increase,and the club convergence effect and Matthew effect will also increase.The geographical spatial patt
