Description
Summary:As an important focus of China’s new urbanization construction, the policy of “city–industry integration” has played a key role in promoting the sustainable development of urban construction. This paper integrates the three major elements of social service, ecology and environment, and science and technology into the traditional indicator system of “industry, city, and people”. Firstly, the PSO-AHP-EM model was constructed to empower the indicators subjectively and objectively, and the degree of city–industry integration was sorted by the GRA-TOPSIS model. Secondly, the Gini coefficient and Theil index were used to further explore the non-equilibrium of city–industry integration development. Finally, an empirical study was conducted on 18 prefecture-level cities in Sichuan Province from 2010 to 2019, and their development laws were analyzed. The results show that: (1) The weights obtained by the PSO-AHP solution were better than the weights obtained by AHP. (2) The level of city–industry integration in Sichuan was not high, and most cities need to be further developed. (3) The regional difference of city–industry integration was relatively small, and the main source of the difference was Chengdu Plain Economic Zone. This paper puts forward some suggestions to provide scientific support for the evaluation of city–industry integration.
