Regional Difference,Distribution Dynamics and Convergence of Imports of Grain Virtual Cultivated Land Resources in China
The Dagum Gini coefficient,kernel density estimation and convergence analysis were used to empirically study the re-gional differences,distribution dynamics and convergence of the imports of grain virtual cultivated land resources in 31 provinces of China from 2002 to 2022.The results show that although the imports of grain virtual cultivated land resources in China and the three major regions show an increasing trend,the spatial difference and gradient effect are obvious.The spatial differences for the imports of grain virtual cultivated land resources are mainly inter-regional differences.The dynamic distribution of the imports of grain virtual cultivated land resources in China and the three regions varies significantly,among which there is both 8 convergence and βconvergence in the whole country and the central and western regions,while there is only βconvergence in the eastern region.According to the research results,it is proposed to clearly realize the regional non-balance of the imports of virtu-al cultivated land resources and adapt to local conditions,to give full play to the comparative advantages and force the upgrading of agricultural industrial structure,to promote the coordinated development of the imports of virtual cultivated land resources,and"effective market"and"promising government"still need to complement each other.
