A resource-based city is a type of city characterized by the exploitation and processing of natural resources as the leading industry in the region. Such cities provide essential resources for China's economic development and support long-term rapid economic growth. However, resource-based cities (RBCs) face challenges, including resource depletion, economic recession, environmental pollution, and ecological damage, to which not enough attention has been paid. In the context of China's increased focus on environmental protection and the economy, improving industrial ecological efficiency of RBCs has become ever more important. In the present study, the Super-SBM model was used to measure the industrial ecological efficiency of 114 RBCs in China from 2003 to 2016. The results show that during the study period, the industrial ecological efficiency of RBCs in China improved significantly, particularly in the central and western regions. The results from a Tobit model show that appropriate environmental regulation and financial pressure have a positive impact on the industrial ecological efficiency of RBCs. However, when faced with the dual pressures of environmental regulation and financial difficulty, improvement in industrial ecological efficiency was inhibited. The impact of environmental regulation and financial pressure on industrial ecological efficiency of cities in different regions and development stages and with different resource types shows heterogeneity. In accordance with the study findings, differentiated measures and suggestions are proposed to improve the industrial ecological efficiency of RBCs.
资源型城市是以本地区自然资源开采、加工为主导产业的城市类型。这些城市为中国的经济发展提供了重要的资源支撑，支持了长期快速的经济增长。然而，资源型城市（RBCs）面临着资源枯竭、经济衰退、环境污染和生态破坏等挑战，这些挑战尚未得到足够的重视。在中国日益重视环境保护和经济发展的背景下，提高资源型城市的产业生态效率变得尤为重要。本研究运用超效率 SBM 模型，测算了 2003—2016 年中国 114 个资源型城市的产业生态效率。结果表明，研究期间，中国资源型城市的产业生态效率显著提高，尤其是在中部和西部地区。Tobit 模型的结果表明，适当的环境规制和财政压力对资源型城市的产业生态效率具有正向影响。然而，当面临环境规制和财政困境的双重压力时，产业生态效率的提升受到抑制。环境规制和财政压力对不同地区、不同发展阶段和不同资源类型城市产业生态效率的影响存在异质性。根据研究结果，提出了差异化的措施和建议，以提高资源型城市的产业生态效率。
