西部地区农业生态效率时空演化及影响因素研究
Study on the Spatiotemporal Evolution and Influencing Factors of Agricultural Ecological Efficiency in the Western Region
摘要
Abstract
To explore the spatiotemporal dynamics and influencing factors of agricultural ecological efficiency in the China's western region,this study selected panel data from 12 provinces(including autonomous regions and munici-palities)involved in the Western Development Strategy from 2013 to 2022 as the research sample.By employing methods such as the non-expected output SBM super-efficiency model,Malmquist index,and Tobit model regression analysis,the agricultural ecological efficiency of the region was evaluated and calculated,and its spatiotemporal evo-lution characteristics were analyzed.On this basis,the key elements influencing the agricultural ecological efficiency in the western area were explored.The results show that:first,the agricultural ecological efficiency in the western region shows an overall upward trend;second,there are significant spatial differences in agricultural ecological effi-ciency among various regions;third,the rate of urbanization,intensity of fertilizer use,level of mechanization,and agricultural planting structure are key elements that considerably influence the ecological efficiency of agriculture.Promoting the rationality of input in production factors,adjusting the industrial structure,innovating in agricultural science and technology,and enhancing agricultural ecological efficiency and improving fiscal policies to support ag-riculture are important ways to enhance agricultural ecological efficiency and promote sustainable agricultural devel-opment in the western region.关键词
