Study on the Spatial-Temporal Differentiation and Influencing Factors of Agricultural Eco-Efficiency in the Three Economic Regions of Shandong Province
Under the background of"double carbon",the use of agricultural production factors is limited.It is particularly necessary to realize agricultural green production and improve the utilization rate of agricultural resources for realizing agricultural and rural modernization as soon as possible.Shandong Province strives to build a model of rural revitalization of Shandong,and it is more urgent to improve agricultural ecological efficiency.Based on this,this paper firstly used SBM super efficiency model to comprehensively measure agricultural eco-efficiency in Shandong Province,then used standard deviation ellipse and Dagum Gini coefficient to analyze the spatial evolution trend and spatial development difference of agricultural eco-efficiency in Shandong Province,and finally used benchmark regression model to analyze the influencing factors of agricultural eco-efficiency in Shandong Province.On the whole,agro-ecological efficiency in Shandong Province has been significantly improved,reaching a relatively high level within the province,but there are significant differences between the three economic circles and cities within the economic circle,and the development is not balanced.In addition,rural electric power facilities,rural water conservancy facilities,land scale level,industrialization level,financial support for agriculture,agricultural mechanization level,and economic development level have a significant impact on the improvement of agricultural ecological efficiency in Shandong Province.
