Spatiotemporal Pattern Differentiation and Influencing Factors of Cultivated Land Use Efficiency in Hubei Province under Carbon Emission Constraints

The rapid conversion of cultivated land resources has posed a severe danger to national food security, where the primary concerns are quantity as well quality being cultivated. Cultivated use efficiency (CLUE) reflects rational allocation and utilization level land, labor, capital, other factors so maximize output minimize cost. In this study, carbon emissions were included an unexpected into measurement framework CLUE. super SBM undesirable model, Spatial analysis Tobit model comprehensively used measure difference pattern influencing CLUE in 72 counties Hubei Province from 2005 2020. results show following: showed significant regional differences temporal variation characteristics. During observation period 2020, overall increased, reaching 0.7475 by but was still at low (less than 1). Due limitation topographic factors, does not obvious spatial agglomeration characteristics on whole. general, value formed after considering emission index most decreased different ranges compared without index. From perspective transverse terrain comparison, measured that mountain hill higher plain. vertical time regions upward trend, indicating study period. farmers’ income can actively promote improvement Province. Urbanization level, rural power consumption, per capita scale, agricultural mechanization have impact whole, heterogeneity. This provide theoretical technical reference for formulation protection strategies policies.
