National strategies for governance modernization and new-type urbanization have raised the bar for urban sustainable development. However, the mechanism linking urban resilience and land green use efficiency, crucial foundation for urban governance and land use planning and regulation, remains unclear and poses a significant challenge to the scientific guidance of sustainable urban development. This research will explore the theoretical interaction mechanism between urban resilience and land green use efficiency. The specific research logic is as follows: building upon the reinterpretation of urban resilience and land green use efficiency, along with theories including evolutionary resilience, sustainable development, and regional human-land systems, and employing literature review and analytical methods, this study developed an analytical framework to explore the interaction mechanism between urban resilience and land green use efficiency. The results showed that: 1) Urban resilience is a complex concept, the connotation of urban resilience has formed a framework of "multidimensional integration, multi capability transformation, and multi perspective evaluation"; 2) Urban land green use efficiency is a product of the new green development concept and sustainable development theory, aimed at maximizing the economic, social, and environmental benefits of land within the region with minimal resource input, and achieving optimal land use; 3) A complex interplay exists between urban resilience and land green use efficiency; On the one hand, urban resilience can affect land green use efficiency through industrial structure transformation, technological innovation transmission pathways, and spatial spillover effects; On the other hand, the efficiency of green land use can be feedback to urban resilience through the transmission of local government financial pressure and the adjustment of urbanization level. This study proposes that, on the basis of fully identifying the types and degrees of coupling and coordination between urban resilience and land green use efficiency in different types cities, in terms of actual cities exhibiting a lack of integrated coordination between urban resilience and land green use efficiency, there is a need to concentrate on diverse city types (ranging from urban functions to urban scale), leverage appropriate planning, systems, and policies, and execute tailored regulatory strategies to foster the harmonization and enhancement of urban resilience and land green use efficiency, thereby supporting the sustainable development of cities that meet higher standards.
