时空维度下城镇化内部协调性研究——基于江西省市级面板数据

首先,基于城镇化协调度评价指标体系,采用组合评价方法确定指标的权重,测算出城镇化综合指数D;其次,基于协调度模型公式得出江西省内各设区市四类城镇化间的协调系数CE;然后,测度各设区市城镇化的内部协调发展指数F,并进行时空两个维度分析。结果显示,11个设区市的城镇化率在15年期间均实现了不同幅度的增长,且城市间的差异得到了有效缩小,这有利于地区间城镇化协调发展。同时,这期间江西省始终保持着"北高南低"的空间分布特征,城镇化耦合协调发展水平较高的城市集中在江西省北部地区。最后,从沟通机制、平台技术、科学规划等方面给出提升城镇化内部协调性的措施。

First, based on the index system of coordination of urbanization, this paper uses combination evaluation method to determine index weights and compute comprehensive index D of urbanization. Second, based on model of coupling coordination, it ob- tains coordination coefficient CE of four types of urbanization, and then computes inner coordination F of each city to analyze the coordination from two aspects involving time series and space alienation. Results show that 11 cities increase to different extent in 15 years, and difference between cities decreases significantly, which contributes to harmonious development be- tween areas. Meanwhile, Jiangxi keeps the ＂higher in the North and lower in the South＂ character of spatial distribution, and cities that have high levels of coordination of urbanization all locate in north area of Jiangxi province. Last, it provides mea- sures of enhancing inner coordination of urbanization from communication mechanism, platform of technology, scientific plan and other aspects.
