基于熵权-灰色关联-TOPSIS方法的山东省低碳经济综合评价

Comprehensive Evaluation of Shandong Low- carbon Economy Based on Entropy Weight and Grey Correlation and TOPSIS

通过构建低碳经济发展评价指标体系,利用熵权法确定指标权重、灰色关联法判断样本关联程度、TOPSIS法对样本排序,从纵向与横向两个维度对山东省低碳经济发展水平进行综合评价,结论表明,山东省低碳经济呈现越来越好的发展趋势,但同东部沿海其它10个省市比较,山东省低碳经济发展水平较低,在低碳产出、低碳能源、低碳技术等主要评价指标方面,与其他省市相比均有较大的差距。

The low-carbon economy is the milestone of economy developing from quantity to quality. This article builds a low-carbon economic development evaluation index system and evaluates the development of low -carbon economy of Shandong Province from both vertical and horizontal dimensions by determining the index weight with the method of entropy weight,determining the degree of association of samples with the method of Gray correlation,and sorting the samples with TOPSIS. The conclusion shows：the low-carbon economy of Shandong Province is better and better,but compared with the other 10 eastern coastal provinces,the development of low-carbon economy is relatively low. Its main indexes of the low-carbon output,low-carbon energy,and low-carbon technology have a larger gap with the other provinces.
