城市要素聚集能力评价及耦合协调度研究--以陕西省为例

Evaluation and Coupling Coordination Degree of Urban Factor Aggregating Capability——A Case Study of Shaanxi Province

通过构建人口、土地、经济、金融、创新、公共服务、文化、对外开放和生态环境9种城市要素聚集能力的综合评价指标体系,借助熵值法、耦合协调模型,测度评价陕西省城市要素聚集能力及其耦合协调度的空间分布格局及特征.研究发现:城市综合要素聚集能力在区域上表现为关中、陕北、陕南依次递减的空间格局,在城市层面呈现出以西安为核心的"单级"发展模式,且该种特征已经形成"惯性";金融、对外开放和创新要素聚集能力表现出明显的"空间剥夺"现象,而文化及生态环境聚集能力体现为"零散"分布特征;西安和咸阳要素聚集能力处于高水平耦合阶段,而其余城市均位于磨合阶段.西安要素聚集能力为极度协调,商洛为低度协调,其余城市均为中度协调;不同城市要素聚集能力耦合度和协调度的变动根源存在较为明显的差异,但对外开放和生态环境要素聚集能力是大部分地区耦合协调度变动的原因.

By constructing a comprehensive evaluation index system for the factor aggregating capabilities,including population,land,economy,finance,innovation,public service,culture,opening-up,and ecological environment,the entropy method and coupling coordination model are used to measure and evaluate the factor aggregating capability of Shaanxi Province.Then,this paper analyzes the spatial distribution characteristics of the factor aggregating capability and its coupling coordination degree.The results are listed as follows.Firstly,in terms of region,the urban comprehensive factor aggregating capability shows a spatial pattern of decreasing order in Guanzhong,Northern Shaanxi,and Southern Shaanxi,and presents a"single-level"development model with Xi’an at the regional core,and this characteristic has become a normal state.Secondly,the factor aggregating capabilities of financial,opening-up and innovation all show a clear"spatial deprivation"phenomenon,while the factor aggregating capabilities of culture and ecological environment both show the characteristic of"scattered".Thirdly,high-level coupling cities include Xi’an and Xianyang,while the remaining cities are located in the running-in stage.The extremely coordinated city includes Xi’an,the low-coordinated city includes Shangluo,and the rest are moderately coordinated cities.Finally,there are obvious differences in the root reasons of the changes in the coupling and coordination of urban factor aggregating capability in different regions,but the factor aggregating capabilities of opening-up and ecological environmental are the reason for most regions.
