Abstract
Industrial green development is an important part of the global sustainable development goals, and it is the only way for China to achieve the "dual carbon goals". This paper aims to explore the methods and indicators for the assessment of the level of industrial green development, and emphasizes its applicability in the "city area" scale. According to the characteristics of industrial green development, an evaluation system including 4 first-level indicators of economic benefits and structure, technological innovation and investment, environmental impact and governance, resource consumption and reuse, and a total of 16 s-level indicators were established, each indicator was determined using the entropy value theory The weight value is based on the conditions of 15 sub-provincial cities across the country to determine the standard value of each indicator. Through the set pair analysis of the five-element connection number and partial connection number, the comprehensive connection degree and the full partial connection number are obtained, so as to evaluate the level of industrial green development in Chengdu static evaluation and dynamic analysis. The results show that the constructed index system and evaluation method are applicable to the evaluation of industrial green development at the "city" scale. The current status of Chengdu's industrial green development is at a qualified level, and the industrial process will have a more active and green development trend in the future. The government management department should formulate appropriate management policies and strengthen comprehensive evaluation and research, so as to take the green industrial development process of Chengdu to a new level.
