Comprehensive Evaluation of Low-carbon Economic Development in Guangdong Province Based on Weighted GRA-TOPSIS Method

摘要

Firstly, the connotation of regional low-carbon economy development is deeply analyzed, and the evaluation index system reflecting regional low-carbon economic progress level is constructed. Secondly, the grey correlation analysis is introduced to judge the correlation degree of all samples, with the index weight determined by method of entropy; then the TOPSIS method is used for data calculation and sample ranking. Using the above steps, a comprehensive estimation for low-carbon economic development in Guangdong province is exerted from dimensions of vertical and horizontal. The results show the low-carbon economy in Guangdong possesses a good level of development, and most of the evaluation values are in the forefront of coastal regions China, also the trend of its low-carbon economy is getting better and better year by year. However, the shortness of low-carbon consciousness and the backwardness of ecological benefits have also restricted the growth potential of low-carbon economic progress in Guangdong. The research conclusions can provide a reference for the low-carbon capacity elevation in Guangdong as well as the coordinated progress for low-carbon economy in other regions.
