摘　　要：基于一种新的Malmquist-Luenberge指数测算中国12个棉花主产省份棉花环境全要素生产率及其成分,并运用Dagum基尼系数及其分解方法对中国棉花环境全要素生产率的区域差异及其来源进行研究。结果表明:1)2000-2018年,中国棉花环境全要素生产率平均增长率为0.3%,高于市场全要素生产率,技术进步是中国棉花环境全要素生产率增长的主要来源;2)黄河流域棉区和长江流域棉区棉花环境全要素生产率均高于西北内陆棉区,环境因素对中国各省份棉花全要素生产率的排名有显著影响;3)中国棉花环境全要素生产率的总体差异有缩小的演变趋势,这一趋势在2010年之后表现的更为明显,棉区间差距是中国棉花环境全要素生产率总体差距的主要来源。Based on a new Malmquist-luenberge index,cotton environmental total factor productivity(TFP)and its components in 12 major cotton producing provinces of China were calculated.The regional differences and sources of cotton environmental TFP were further studied by Dagum Gini coefficient and its decomposition method.The results show that:(1)during 2000-2018,the average growth rate of cotton environmental TFP in China was 0.3%,higher than that of cotton market TFP,and technological progress was the main source of the growth of cotton environmental TFP in China.(2)Cotton environmental TFP in the Yellow River region and Yangtze River region was higher than that in northwest inland region,and environmental factor had a significant impact on the ranking of China’s cotton TFP.(3)The overall difference of China’s cotton environmental TFP had a narrowing trend,which was more obvious after 2010.The gap between cotton regions was the main source of the overall gap of China’s cotton environmental TFP.
