Eco-industrial parks, as complex ecosystems at the regional scale, involve multi-dimensional interactions in terms of management, environment, economy, and society in their development. Given their complexity, it is difficult for a single indicator to comprehensively assess their sustainable development status. To promote sustainability and inclusive development of industrial parks, the World Bank Group published “the International Framework for Eco-Industrial Park” as a green evaluation benchmark. This paper examines the applicability of this framework in Chinese industrial parks, focusing on 17 cases in Jiangxi Province supported by the China-Jiangxi Eco-Industrial Parks Project. This study analyzes the indicator composition of the international EIP framework and compares it with the standardization system of eco-industrial parks in China. Through questionnaire surveys and dialogue interviews, this paper analyzed the compliance, practicality, and necessity of implementing the international EIP framework. Quantitative assessment using the analytic hierarchy process and the fuzzy comprehensive evaluation model revealed that the framework is well suited to Chinese conditions, scoring over 80, reaching the “applicability level”. This research provides a scientific basis for park management, advocating for international concepts in park development. It also underscores the importance of a comprehensive framework for park construction, intelligent management strategies, and enterprise empowerment, collectively contributing to sustainable park development and enhanced international competitiveness.
