Conflict or Coordination? Assessment of Coordinated Development between Socioeconomic and Ecological Environment in Resource-based Cities ： Evidence from Sichuan Province of China

The relationship between socioeconomic and ecological environment become a significant factor influencing the sustainable development of resource-based cities (RBCs), the transformation of RBCs is a key component of regional high-quality development. A comprehensive evaluation indicator system was constructed to research the coupling coordination level of RBCs in this paper, the dynamic DM model and the CCD model were adopted to measure the comprehensive level of the coupling coordination degree between socioeconomic and ecological environment of the 9 resource-based cities in Sichuan province. The results showed that the coupling coordination level was not ideal. Only two cities were located to the moderate coordination, and other cities were located to the primary coordination or tiny coordination. In addition, there was a significant different between SE and EE, and the comprehensive evaluation score of SE was lower than that of EE in eight RBCs, which accounting for 88.89%. Based on this, the policy suggestions for the sustainable development of different type of RBCs were provided. This study offers a model of China’s experience that might be benefit for achieving sustainable development goals (SGDs) of other cities and countries.
