Study on the spatial-temporal differentiation of the coupling coordination degree of new-type urbanization, rural revitalization and ecological environment: A Case Study of Henan Province

In the new stage of development where the "dual carbon" strategy and the goal of common prosperity are being advanced in parallel, China"s new-type urbanization and rural revitalization strategies are undergoing a paradigm shift from geographic spatial expansion to a multidimensional integration of ecological, social, and economic systems. This study focuses on the key ecological barrier regions of the Yellow River Basin, taking Henan Province—located at the core of the Central Plains Economic Zone—as a case study. Based on complex system theory, a three-dimensional evaluation system is constructed. Using the Coupling Coordination Degree Model, Kernel Density Estimation, and Spatial Markov Chain Analysis, the coupling coordination degree between new-type urbanization, rural revitalization, and the ecological environment system from 2011 to 2022 is calculated and analyzed. The study explores the evolution characteristics of coupling coordination development from a spatial-temporal perspective. The results indicate that: (1) The coupling coordination level in Henan Province has shown a stable development trend over time. The coupling coordination degree of cities has gradually improved from a near-disequilibrium state to a primary coordination state. Spatially, the Central Plains Urban Agglomeration centered around Zhengzhou exhibits a higher level of coupling coordination, while the southern and eastern parts of Henan Province show relatively lower coupling coordination levels. However, the disparity between regions is gradually narrowing. (2) The coupling coordination types of cities in Henan Province show synergistic effects with those of neighboring regions. The neighborhood effect significantly influences the regional coupling coordination degree, with regions in a low-coordination type showing a significantly higher probability of upward transition. (3) In view of the unbalanced development in Henan Province, it is necessary to strengthen the radiating leading role of core cities, accurately support backward regions, build cross-regional coordination mechanisms, and promote balanced development of all regions. This study innovatively constructs an evaluation framework for the coordinated development of multiple systems, revealing the spatial interaction mechanisms of regional complex system co-evolution. It provides a scientific basis for the implementation of high-quality development strategies in Henan Province.
