The Spatial and Temporal Evolution of Coordination Degree Concerning China's Cultivated Land Green Utilization Efficiency and High-Quality Agricultural Development

The cultivated land green utilization efficiency (CLGUE) is closely related to high-quality agricultural development (HAD), but the evolutionary characteristics of the relationship between HAD and CLGUE have received little study. In the context of the rural revitalization strategy and high-quality development in China, it is important to ensure food security and cultivated land system security through coordinating HAD and CLGUE. In this study, 31 Chinese provinces were used as the research object, and the entropy weight TOPSIS model and SBM-Undesirable model were used to measure HAD and CLGUE, respectively. In addition, the coupling coordination degree model and the geographical analysis model were used to investigate the development of coordination degree concerning HAD and CLGUE from both geographical and temporal perspectives. The following findings are the result of this study. Firstly, both China's overall HAD and CLGUE exhibited an upward tendency, with average annual growth rates of 4.35% and 4.08%, respectively. Secondly, there was a volatility upward trend shown by the level of coordination degree regarding HAD and CLGUE in China. Additionally, the coordination degree showed significant spatial-temporal disparities across the 31 provinces due to the variance in the natural endowment of agricultural development resources. Lastly, the coordination degree concerning HAD and CLGUE throughout China showed obvious patterns of spatial agglomeration at the provincial level. However, the geographical aggregation and dispersion of the provinces with high or low coordination levels have diminished somewhat. Furthermore, there was a conversion from hot spot aggregation regions in MGPAs to cold spot aggregation regions in GPMBAs. The conclusions of the present study enrich the theoretical literature on the relationship between HAD and CLGUE, and provide an empirical reference for the policy maker of the developing pathway of "high HAD and high CLGUE".
