摘要
提高物流业绿色全要素生产率是建立绿色物流体系的核心.文章通过构建非期望产出的全局SBM模型和GML指数,测算1998-2020年中国其中30个省市的物流业绿色全要素生产率,运用Dagum基尼系数分析东、中、西部地区的差异及其来源,最后建立空间计量模型检验其收敛特性.研究结果表明:样本期内中国物流业绿色全要素生产率呈波动上升趋势,但发展依旧不平衡,空间上呈现“东强西弱”格局;区域间差异是主要的差异来源,区域内差异贡献率一直维持在30%左右;物流业绿色全要素生产率低的地区有望赶超效率高的地区,最终达到同一水平;物流业绿色全要素生产率的增长与收敛受空间因素的影响且存在地区异质性,东部优化产业结构,中西部加强能源基础建设和研发投入可以有效缩小区域内部绿色物流发展差距,同时各地区应综合衡量地区要素投入对本地的促进作用以及对邻地的负向阻碍作用,以实现地区的协调发展.文章借助以上分析为构建绿色物流体系提供理论支撑,以促进中国物流业绿色健康发展.
Improving green total factor productivity(GTFP)is the core of establishing a green logistics system.This paper constructs a global SBM model of undesirable output,and employs the GML index to calculate the GTFP of the logistics industry in 30 provinces selected from China between 1998 and 2020.Then,the Dagum Gini coefficient is used for analyzing regional differences and the causes.Finally,a spatial econometric model is established to identify the convergence mechanism.According to the research findings:During the sample period,while the GTFP of logistics in China gyrates up,growth imbalance remains a concern,with the GTFP level in the east being far higher than in the west;The differences between regions are the primary cause of the imbalance;the difference in the rate of contribution in the same region stays at around 30%;the regions with lower GTFP levels in logistics are expected to catch up with those with higher GTFP levels and finally achieve the same level;the growth and convergence of GTFP in logistics are affected by spatial factors and show regional heterogeneity;the eastern region may optimize the industrial structure,while the middle and western regions may increase their investment on energy infrastructure and R&D to bridge the growth gap of green logistics in the region;coordinated development of different regions can be realized based on a comprehensive measurement of the positive impacts of factor inputs on the local region and negative impacts on neighboring regions.The aforementioned analysis provides a theoretical basis for the construction of the green logistics system that will help promote the healthy and sustainable development of the logistics industry in China.
