The Spatial-Temporal Evolution and Influencing Factors of Agricultural Ecological Efficiency at County-Level in Hebei Province
In recent years,the state attaches great importance to the development of agricultural ecology.There are great differences in the natural geographical conditions and levels of agricultural economic development of different counties in Hebei Province,so the study on county-level agricultural ecological efficiency can facili-tate sustainable development of agriculture.This paper used the super-SBM model to measure the agro-eco-logical efficiency of 167 counties in Hebei Province from 2011 to 2020,and then studied the temporal evolution of agro-ecological efficiency from the two levels of county as a whole and ecological area.Then it studied the spatial distribution pattern and spatial direction evolution of agricultural ecological efficiency using ArcGIS soft-ware,and finally carried out the spatial effect test on the agricultural ecological efficiency of counties in Hebei Province,and studied the influencing factors of agro-ecological efficiency by spatial econometric analysis tools.The paper finds that from 2011 to 2020,the counties with high agricultural ecological efficiency in Hebei Province were mainly concentrated in the northwest and northeast of Hebei Province.During the study period,the overall agro-ecological efficiency showed a trend of first increasing and then slowly decreasing.The spa-tial distribution of agro-ecological efficiency is agglomerated,and the position and distribution range of the standard deviation elliptic center of gravity are shifted to the southwest as a whole.There is a spatial effect on agricultural ecological efficiency.Some factors have positive effects on agricultural ecological efficiency such as agricultural industrial structure,farmers' income level,agricultural machinery density and urbanization rate,while other factors have negative effects on agricultural ecological efficiency such as fertilizer use intensity,irri-gation rate and agricultural scale.To improve the ecological efficiency of counties in Hebei Province,it is nec-essary to give full play to the technical ecological efficiency and develop moderate-scale agricultural opera-tion;combined with the spatial distribution pattern,improve regional ecological efficiency;improving the utili-zation efficiency of agricultural resources,promote energy conservation and pollution reduction in agricultural production;optimizing the structure of agricultural industry,improve the income level of farmers;increasing government support,adhere to development according to local conditions.
