西部地区物流业效率与低碳化水平的互动关系分析

Analysis of the Interactive Relationship between Logistics Efficiency and Low Carbonization Level in Western China

基于2008-2021年西部地区面板数据,采用非期望产出Super-SBM模型和Malmquist指数模型测度物流业效率,利用全局主成分分析法评估物流业低碳化水平,通过构建耦合协调度模型和PVAR模型,实证检验物流业效率与低碳化水平之间的互动关系。结果表明:(1)西部地区物流业动态效率呈波动增长趋势,但静态效率相对较低。(2)物流业低碳化水平在不同地区存在显著差异,重庆、陕西、新疆、四川和甘肃等地区低碳化水平相对较高。(3)物流业静态效率与低碳化水平呈现初级协调状态,并且逐渐向好发展。2013-2021年期间,物流业低碳化发展优先于效率提升。(4)短期内,物流业动态效率对低碳化水平具有一定促进作用,但同时也受到低碳化水平的抑制影响。

Based on the panel data of various regions in western China from 2008 to 2021.this paper uses the non-expected output Super-SBM model and Malmquist index model to measure the logistics industry efficiency.and uses the global principal component analysis method to evaluate the low carbonization level of the logistics industry.By constructing the coupling coordination degree model and PVAR model.The interactive relationship between logistics efficiency and low carbonization level was tested empirically.The results show that:(1)The dynamic efficiency of logistics industry in western China shows a fluctuating growth trend.but the static efficiency of logistics industry is relatively low.(2)There are significant differences in the low carbonization level of logistics industry in different regions.and the low carbonization level of Chongqing.Shaanxi.Xinjiang.Sichuan and Gansu is relatively high.(3)The static efficiency of logistics industry and the low carbonization level show a primary coordination state.and gradually develop towards a better development.From 2013 to 2021.the low carbonization development of logistics industry takes priority over the improvement of efficiency.(4)In the short term.the dynamic efficiency of logistics industry has a certain promotion effect on the low carbonization development.but it is also inhibited by the low carbonization development to a certain extent.
