城市低碳经济发展水平动态综合评价——以安徽省为例

Dynamic comprehensive assessment of urban low carbon economy

据现有关于低碳经济和城市低碳经济评价指标的文献和理论,构建了从经济技术、社会发展、生态环境、能源排放4个方面城市低碳经济发展水平评价指标体系,运用纵横向拉开档次对安徽省16个地级市2011-2015年低碳经济发展水平进行动态综合评价分析,并利用余期望系数对其低碳经济发展水平差异进行测算与分析。结果表明2011-2015年安徽省16个地级市中除合肥与黄山低碳经济发展水平属于中高碳,其他14个地级市低碳经济发展水平都处在高碳范围;通过聚类分析,将安徽省低碳经济发展水平划分4类;从总体来看,2011-2015年安徽省16个地级市低碳经济发展水平整体上在扩大,但有缩小的趋势;各地级市低碳经济发展水平总体差异主要是受组间差异影响的。

Based on the present literature and theories on the evaluation index of low-carbon economy and urban low-carbon economy,the evaluation index system for the development level of urban low-carbon economy in terms of economy,technology,social development,ecological environment and energy emission is constructed.The low-carbon economy development level of 16 prefecture-level cities in Anhui province in 2011-2015 was dynamically and comprehensively evaluated and the expected surplus coefficient was employed.The results show that the development level of low-carbon economy in Hefei and Huangshan was medium and high,and the rest cities were characterized with high carbon.According to cluster analysis,the development level of low-carbon economy in Anhui falls into four categories.Overally,development level of low-carbon economy in 16 prefecture-level cities in Anhui province was on the rise in 2011-2015.The overall level of economic development is mainly affected by differences between groups.
