摘要
通过SBM模型和Malmquist指数,考察西部十二省物流业2010~2018年物流业碳排放效率、全要素效率及其分解因素,同时对数据进行收敛性分析。结果表明:考虑碳期望产出的各区物流业效率低于不考虑期望产出的各区物流业效率。同时,西南地区的各指数效率明显高于西北地区指数效率。中国西南、西北、西部地区既存在着σ收敛,又存在着绝对、条件β收敛,其物流业效率时空演变特征与收敛性分析渐缩小。
Through the SBM model and the Malmquist index,the carbon emissions efficiency,total factor efficiency,and decomposition factors of logistics industry in the western 12 provinces in 2010~2018 are investigated,and the data is analyzed for convergence.The results show that the efficiency of the logistics industry in each region considering the expected carbon output is lower than the efficiency of the logistics industry in each region that does not consider the expected output.At the same time,the efficiency of each index in the southwest is significantly higher than that of the northwest.In the southwest,northwest,and western regions of China,there is both convergence and absolute and conditional convergence.The analysis of the characteristics of the spatiotemporal evolution of the efficiency of the logistics industry and its convergence have gradually narrowed.
