京津冀城市外向度与发展水平耦合协调研究

Coupling coordination between extroversion and developing levels in Beijing-Tianjin-Hebei area

以京津冀城市群为研究区域,建立城市外向度和发展水平的指标体系,构建耦合协调模型,计算13个地级及以上城市2016年的外向度和发展水平指数以及二者的耦合协调度.根据计算得出的耦合协调度指数的高低将13个城市划分为4级.结果发现:京津冀城市外向度和发展水平二者并非同步发展,13个城市外向度均小于发展水平;二者的耦合度基本处于颉颃阶段,协调度水平总体较低,区域差异明显.

An index system of urban extroversion and developing level is established for the BeijingTianjin-Hebei area,to construct a coupling coordination model and calculate extrovert and development level index and coupling coordination.The thirteen cities in the area are divided into 4 levels according to coupling coordination.Marked regional differences are noted in urban extroversion and development level.The two systems do not show synchronous development,city extroversion is less than development level.The coupling degree of the two system is basically in the period of antagonism,the level of coordination degree is not high,regional differences are rather marked.
