Measurement of Urban and Rural Resilience and Their Coupling Coordination Relationship in Northeast China

Studying the spatiotemporal distribution characteristics and coupling coordination relationship of urban and rural resilience is of substantial theoretical and practical significance to improving the ability of urban and rural areas to resist risk and for promoting their coordinated development. This study establishes a comprehensive evaluation index system of urban and rural resilience that encompasses industrial, social, and ecological subsystems as well as stability, sensitivity, and adaptability. For each of the prefecture-level city in Northeast China, we evaluated its urban and rural resilience and determined the coupling coordination level between them using data spanning 2010, 2015, and 2020. The resilience levels of both urban and rural areas in Northeast China are continuously improving. The high-value area of urban resilience is mainly located in the central cities of Northeast China, and prominent in urban agglomeration areas, while rural resilience is predominantly high in the north and low in the south. The high-value area of the coupling coordination degree is mainly distributed in the arc-shaped zone extending from south to north in the eastern part of Northeast China, with the level of coupling coordination increased overall. Non-parametric testing revealed significant differences in urban industrial stability, urban industrial adaptability, rural industrial stability, rural social adaptability, and rural ecological stability among types of cities differing in their coupling coordination development. Our findings provide a reference for enhancing urban and rural resilience and their coordinated development path in Northeast China.
