Abstract 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.
