江苏物流业配置效率的地区差异及动态演进

Regional Differences and Dynamic Evolution of Logistics Industry Allocation Efficiency in Jiangsu Province

文中基于2013-2021年江苏市级面板数据,利用全局参比下超效率SBM模型、Theil指数以及Kernel核密度估计分析江苏物流业要素配置效率的地区差异及动态演进。研究表明:(1)江苏物流业要素配置效率整体处于上升阶段,其中苏南的物流业配置效率最好,苏北地区物流业配置效率最差;(2)江苏物流业配置效率的地区差异整体上呈现下降趋势,其引起地区差异的主要原因为地区内差异,其中苏北地区的地区内差异最高,苏南地区的地区内差异最低;(3)江苏物流业配置效率密度总体呈现右移趋势且右拖尾现象逐渐消失,说明江苏物流业配置效率呈现上升趋势且多极化现象减弱。

Based on the municipal panel data of Jiangsu from 2013 to 2021,this paper analyzes the regional differences and dynamic evolution of factor allocation efficiency of logistics industry in Jiangsu by using the Global-Super-SBM model,Theil index and Kernel density estimation.The research shows that:(1)The allocation efficiency of logistics industry in Jiangsu is on the rise as a whole,and the allocation efficiency of logistics industry in southern Jiangsu is the best,while that in northern Jiangsu is the worst;(2)The regional differences in the allocation efficiency of Jiangsu logistics industry showed a downward trend on the whole,and the main reasons for the regional differences were intra-regional differences,among which the intra-regional differences were the highest in northern Jiangsu and the lowest in southern Jiangsu;(3)The allocation efficiency density of logistics industry in Jiangsu generally showed a right-shifting trend and the right-tailing phenomenon gradually disappeared,indicating that the allocation efficiency of logistics industry in Jiangsu showed an upward trend and the multi-polarization phenomenon was weakened.
