Utilization Efficiency of County Cultivated Land and Influencing Factors in Anhui Province
In order to improve the overall utilization efficiency of cultivated land in Anhui Province,the utilization efficiency and influencing factors of cultivated land in 61 counties of Anhui Province were analyzed.Based on the data envelopment analysis model(DEA),the evaluation index of cultivated land use efficiency was constructed,and the cultivated land use efficiency level of 61 counties in Anhui Province from 2000 to 2020 was calculated.The spatial statistical model was used to analyze the spatial and temporal pattern of cultivated land use efficiency in 61 counties in Anhui Province.The main influencing factors of cultivated land use efficiency change in Anhui Province were discussed using Tobit regression model.The results show that the change range of cultivated land use efficiency in Anhui Province is very small.The average value of cultivated land use efficiency in Anhui Province from 2000 to 2020 is 0.759,and the comprehensive efficiency of cultivated land use is at a medium level.In general,since 2000,the spatial distribution pattern of cultivated land use efficiency in Anhui Province has been relatively stable,with no large-scale changes;from a local point of view,the utilization efficiency of cultivated land in counties of Anhui Province shows a significant spatial difference distribution pattern,which is mainly reflected in the spatial polarization of cold and hot spots.Through the Tobit model analysis,it is concluded that the number of rural employees and the per capita sown area of rural labor force have a significant positive impact on the utilization efficiency of cultivated land in counties of Anhui Province.The multiple cropping index of cultivated land and the total power of agricultural machinery per unit area have a negative effect on the utilization efficiency of cultivated land,and the per capita sown area of rural labor force is the main influencing factor.It shows that the utilization efficiency of cultivated land in Anhui Province is at a medium level,and the regional differences are obvious.The discussion of each region can effectively improve the utilization efficiency of cultivated land in Anhui Province.
