以江苏省县域为研究对象,借助随机前沿生产函数模型测度了2001—2013年各县域工业生产效率,运用GIS空间分析技术揭示了其空间格局的演化特征,并建立面板回归模型分析了空间格局演化的影响因素。结果表明:2001—2013年江苏省县域工业生产效率有所提升,但整体水平不高,总体差异较大,相对差异逐年缩小,效率值的空间聚类呈“南高北低”的梯度变化特征;县域工业生产效率的空间关联格局保持相对稳定,高、低值集聚的区域差异不断缩小;效率重心的跃迁过程可分为“2001—2007年西北迁移阶段”和“2007—2013年东北迁移阶段”。江苏省县域工业生产效率空间格局的演化特征是在地区发展水平、外商直接投资、结构因素、交通条件和信息化水平等因素的共同作用下形成的。
Taking the county of Jiangsu Province as the research object, using the stochastic frontier production function model to measure the industrial production efficiency of each county in 2001-2013, using GIS spatial analysis technology to reveal the evolution characteristics of its spatial pattern, and establishing a panel regression model to analyze the spatial pattern evolution. The influencing factors. The results show that the industrial production efficiency of counties in Jiangsu Province has improved from 2001 to 2013, but the overall level is not high, the overall differences are relatively large, the relative differences are decreasing year by year, and the spatial clustering of efficiency values is a gradient of “south high north low” The characteristics of change; the spatial correlation pattern of county industrial production efficiency remains relatively stable, and the regional differences between high and low value agglomerations continue to shrink; the transition process of the efficiency center of gravity can be divided into “2001-2007 Northwest Migration Phase” and “2007— The Northeast Migration Phase of 2013”. The evolving characteristics of the spatial pattern of industrial production efficiency in counties in Jiangsu Province are formed by the combined effect of regional development level, foreign direct investment, structural factors, traffic conditions, and informatization level.
