Abstract: Based on a situation analysis and a literature review, this paper selects 25 measurement indicators from five perspectives, and creates the indicator system and the model of orderly degree in subsystem for measuring synergistic degrees of governance on urban environmental pollution. This paper selects the city of Nanjing, Jiangsu Province, China, as the object of case research, and measures the synergistic degrees of governance on urban environmental pollution in the 11 districts of this city from 2013 to 2021. The measurement results show that the synergistic degrees in all districts had been on a steady rise to about 0.9 by the end of 2021. By contrast, the synergistic degrees in different districts had shown no significant difference in the same year during this period. Furthermore, it can also be concluded that a result of grading a synergistic degree depends not only on a grading standard but also on a valuing method.

Keywords: indicator system; expert surveys; synergistic degrees; synergistic governance; urban environmental pollution; the method of entropy weight; the model of orderly degree in subsystem; grade standards.
