云南农业绿色全要素生产率时空演变及影响因素分析OA北大核心CSTPCD

Based on the panel data of Yunnan cities from 2012 to 2022,the article measures the agricultural green total factor productivity and its decomposition index by using the SBM-GML index method,taking the agricul-tural carbon emission as a non-expected output,and analyzes the spatial and temporal evolution of the agricultural green total factor productivity in prefectures and cities and empirically verifies its impact on the total factor produc-tivity.The findings are as follows:In terms of time series,the level of green total factor productivity in agriculture in Yunnan Province continued to rise during the observation period,with the growth rate showing a low-high-low development trend,mainly driven by technological progress;spatially,the level of green total factor productivity in agriculture shows a distribution pattern of high in the center and west and low in the southeast,and the growth rate exhibits high in the north and low in the south,and the spatial correlation is not significant;level of economic de-velopment has a significant contribution to the growth of green total factor productivity in agriculture in Yunnan Province,and the level of urbanization and agricultural mechanization have a significant inhibitory effect on it.
