基于DEA-Tobit模型的奶牛养殖业绿色全要素生产率的时空特征及影响因素分析OA

In depth research on the spatiotemporal characteristics and influencing factors of green total factor productivity in dairy farming played an irreplaceable role in scientifically establishing a modern framework for Chinese dairy industry and achieving sustainable development in the dairy farming industry.The article was based on provincial panel data from 2014 to 2024,used the DEA-Malmquist index method to measure the total factor productivity and spatiotemporal characteristics of dairy farming,and analyzed the influencing factors of green total factor productivity in dairy farming by constructing a Tobit model.The results showed that from the perspective of temporal evolution characteristics,the green total factor productivity index of dairy farming industry during the research period was 1.138.From the perspective of spatial distribution characteristics,the green total factor productivity of dairy farming showed a spatial agglomeration pattern of decreasing in the East,Middle,and West.From the perspective of influencing factors,technology supply,risk prevention and control of farming diseases and epidemics,level of scale of dairy farming,policy support,and environmental regulations played a positive role in promoting the improvement of green total factor productivity in dairy farming.The study shows that the overall green total factor productivity of dairy farming is gradually increasing,and is influenced by factors such as technology supply,risk prevention and control of farming diseases and epidemics,the level of scale of dairy farming,policy support,and environmental regulations.
