基于模糊数学和灰色理论的城市生态环境竞争力评价

在综合分析了国内外有关城市竞争力理论研究的基础上,对城市生态环境竞争力的概念和内涵进行了界定,构建了面向生态环境竞争力的评价体系,并以山东省17城市为例,采用灰色系统理论确定各指标的权重,利用模糊综合评价法对各市进行综合评价,研究结果表明,生态环境竞争力排名前三的地市为临沂(0.1894)、日照(0.1705)和烟台(0.1676),而德州(0.1191)、济南(0.1232)、枣庄(0.1274)、滨州(0.1285)和淄博(0.1289)表现相对较差,其他地市处于中游水平.分别从资源禀赋竞争力、污染物减量排放竞争力、环境治理竞争力和能耗竞争力4个子维度对典型城市进行分析,指出了存在的问题,并给出了相应的对策建议.

Comprehensive evaluation of urban eco-environment competitiveness based on fuzzy mathematics and gray theory

On the basis of the comprehensive analysis of urban competitiveness at home and abroad, the concept of urban eco-environment competitiveness was defined and an evaluation index system to measure the urban eco-environment competitiveness was constructed. Grey system theory was used to calculate every indicator’s weight and analyze 17 cities of Shandong Province. Each of urban eco-environment competitiveness of these 17 cities was calculated using fuzzy comprehensive evaluation method. The result shows that the top three cities with eco-environment competitiveness were Linyi(0.1894), Rizhao(0.1705) and Yantai(0.1676), however, Dezhou(0.1191), Jinan(0.1232), Zaozhuang(0.1274), Binzhou(0.1285) and Zibo(0.1289) hade poor performances relatively and other cities were in the middle level. In-depth analysis was conducted from different angles, such as environmental resource competitiveness, waste discharge competitiveness, environmental governance competitiveness and energy consumption competitiveness. Finally, typical problems that emerge in the development of low-carbon economy were analyzed and targeted policy recommendations were given.
