Abstract:

Based on the data of private listed enterprises in Yangtze River Delta, we measure the development index of private listed enterprises based on the entropy method, analyze their spatial and temporal development characteristics by combining the exploratory spatial data analysis method, and quantitatively estimate the spatial variation of driving factors by using the econometric model. The results show that: ① During 2003-2018,the top 10 industries occupied by private listed enterprises in the Yangtze River Delta had been mainly manufacturings and services, no matter measured by numbers of enterprises or by revenue, the share of these two industries exceeded 50 percent; ② The private listed enterprises in the Yangtze River Delta show a "northwest-southeast" development pattern, characterized by "diffusion followed by agglomeration and Z-shaped shift", with significant spatial heterogeneity and "polycentric semi The spatial heterogeneity of its spreading area is significant and "polycentric and semi-circular"; ③ The spatial differentiation of driving factors is not significant, and its spatial differentiation changes along a unidirectional gradient, the driving effect is maintained in the positive driving environment of technological innovation, market scale, from positive driving to negative driving traffic accessibility, urban policy environment, from negative driving to positive driving. The driving effects are maintained in the positive direction by technological innovation environment and market scale, in the negative direction by traffic accessibility and urban policy environment, and in the negative direction by production cost and openness to the outside world.

摘要：

基于长三角民营上市企业数据，依据熵权法测度民营上市企业发展指数，结合探索性空间数据分析法解析其时空发展特征，并运用空间计量模型估计驱动因素的空间分异。结果表明：①2003—2018年，无论从企业数量还是从主营收入来看，长三角民营上市企业行业前十位的占比均超过五成。前十行业以制造业为主服务业为辅，主营收入中以批发零售业及制造业为主；②长三角民营上市企业呈现“西北-东南”发展格局，变化特征为“先扩散后集聚，类Z字形偏移”，其蔓延区域空间异质性显著且呈“多中心半环绕型”蔓延；③民营上市企业发展的驱动因素空间分异沿单方向梯度变化，驱动效应维持正向的因素有技术创新环境、市场规模，由正向驱动转为负向驱动的因素有交通可达性、城市政策环境，由负向驱动转向正向驱动的因素有生产成本、对外开放程度。
