本文构建了一个环境物流绩效指数（ELPI）来评估112个国家绿色运输和物流实践的整体绩效。该指数由物流绩效指数（LPI）、二氧化碳排放和运输部门的石油消耗来衡量，使用数据包络分析（DEA）的范围调整测量（RAM）。ELPI有效地反映了物流效率和运输环境保护之间的权衡。本文分析了收入和地区对ELPI得分的影响，并讨论了这些国家在石油消费强度和碳强度方面的降低潜力。研究工作的主要发现是ELPI与LPI具有很强的相关性，并且LPI表现良好的国家通常在ELPI方面表现良好。与LPI的特征相似，ELPI也与收入和地区密切相关。在我们的研究期间，高收入国家表现最好，而撒哈拉以南非洲国家表现最差。然而，一些例外情况，如委内瑞拉、巴西和贝宁，表明物流绩效和绿色交通的发展水平可以超过或落后于其收入或地区集团的同行。
This article constructs an environmental logistics performance index (ELPI) for assessing the overall performance in green transportation and logistics practices of 112 countries. The index is measured by logistics performance index (LPI), CO2 emissions and oil consumption from the transport sector, using a range-adjusted measure (RAM) of the data envelopment analysis (DEA). ELPI effectively reflects the tradeoff between logistics efficiency and environmental protection in transportation. This article analyzes the impact of income and region on ELPI scores and discusses those countries' reduction potential in oil consumption intensity and carbon intensity. The main finding of the research work is that ELPI is strongly correlated with LPI, and countries with high performance in LPI generally perform well in ELPI. Similar to the characteristics of LPI, ELPI is also closely related to income and region. During our study period, high income countries performed best, while Sub-Saharan Africa countries performed worst. However, some exceptions such as Venezuela, RB and Benin, indicate that the level of development of logistics performance and green transportation can outperform or lag behind their income or region group peers.
