Spatial-temporal Differentiation of Ecological Efficiency of Cultivated Land Use and Its Configuration Paths in the Yangtze River Economic Belt
The purposes of this study are to reveal the spatial-temporal differentiation of the ecological efficiency of cultivated land use in the Yangtze River Economic Belt since the 21st century,and to analyze the configuration paths and its evolution.The research methods included Super-SBM model and fuzzy set qualitative comparative analysis(fsQCA).The results indicate that:1)from 2000 to 2021,the ecological efficiency of cultivated land use in the Yangtze River Economic Belt was generally at a medium-low level,exhibiting a U-shaped trend.There were significant differences in the trend of change among 11 provinces.2)There are three configuration paths for improving the ecological efficiency of cultivated land use,which can be summarized as resource-economic driven under technological dominance,resource-technological driven with policy support,and technology-policy driven under the dual logic of resources and the economy.3)The configuration paths for achieving high-level ecological efficiency of cultivated land use showed significant spatial-temporal variations,and there are substitution effects among core conditions.The ecological efficiency of cultivated land use is a systemic issue influenced by factors,such as resources,economy,technology and policy.From the perspective of ecological efficiency improvement of heterogeneous regions in the Yangtze River Economic Belt,the emphasis should be placed on the overall planning and location-specific measures,while strengthening the coordinated linkage of policies on ecological compensation,technological diffusion and environmental regulation to enhance the protection and utilization of cultivated land between river basins.
