基于组合客观权重法的区域社会经济环境评价研究——以贵州省思南县为例

Research on Regional Socio-Economic-Environmental Evaluation Based on Combined Objective Weight Method-Taking Sinan County of Guizhou Province as an Example

随着国家层面的高质量发展,区域协调发展的综合评价是人们关注的热点,区域协调发展评价也从单一评价发展到综合评价。区域社会、经济和环境间存在复杂的耦合关系,为实现区域可持续协调发展,构建由社会、经济和环境3个维度展开的9个二级评价指标22个三级评价指标的综合评价体系,根据贵州省思南县2014-2018年数据,使用变差系数法、熵权法等方法计算社会-经济-环境系统各指标综合权重,再进行耦合协调度计算,为该县可持续发展提供科学依据。结果表明2014-2018年:(1)环境改善的效果相对落后另2个系统,整体可归属于环境相对滞后型;(2)社会子系统的发展先下降后升高再降到初始水平,而经济和环境子系统呈稳定升高趋势;(3)系统耦合度和协调发展度呈逐年上升趋势,现处于高水平耦合及濒临失调发展阶段。

With the high-quality development at the national level,the comprehensive evaluation of regional coordinated development has become a hot topic of concern,and the evaluation of regional coordinated development has evolved from a single evaluation to a comprehensive evaluation.There is a complex coupling relationship between regional society,economy,and environment.In order to achieve sustainable and coordinated regional development,a comprehensive evaluation system including nine secondary evaluation indicators and 22 tertiary evaluation indicators was constructed in terms of three dimensions:society,economy,and environment.According to the data of Sinan County in Guizhou Province from 2014 to 2018,the variation coefficient method,entropy weight method,and other methods were used to calculate the comprehensive weight of each indicator of the social-economic-environmental system.Then the coupling coordination degree was calculated,so as to provide a scientific basis for the sustainable development of the county.The results show that from 2014 to 2018,①the effect of environmental improvement is relatively lagging behind that of the other two systems and can be classified as a relatively lagging type of environment;②the development of the social subsystem first decreases and then increases,and it then decreases to the initial level,while the economic and environmental subsystems show a stable increasing trend;③the coupling degree and coordinated development degree of the system show an increasing trend year by year,and the system is now on the verge of high coupling degree and dysfunctional development.
