摘要
基于2012-2022 年云南各州市面板数据,把农业碳排放作为非期望产出,运用SBM-GML指数法测算农业绿色全要素生产率及其分解指数,在此基础上解析各州市农业绿色全要素生产率的时空演变特征并实证其影响因素.结果表明:在时序上,观测期内云南省农业绿色全要素生产率水平持续上升,增速呈现低—高—低的变化态势,并且主要由技术进步所推动;在空间上,农业绿色全要素生产率水平呈现出中西高、东南低的分布格局,增速表现为北高南低的状态,且空间关联性不显著;影响因素分析结果显示,经济发展水平对云南农业绿色全要素生产率的增长具有显著促进作用,而城镇化水平和农业机械化水平对其具有明显的抑制作用.
Abstract
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.
