全球物流绩效指数合理性验证与应用

The LPI Index's Rationality and Its Application

为评价全球物流绩效指数(logistics performance index,LPI)的合理性,以及在实践中的应用,以“21世纪海上丝绸之路”区域的三大海上航线所涉及国家的LPI指数为样本,运用分层聚类方法和相关性分析技术对LPI指数的合理性进行验证,并据此对“21世纪海上丝绸之路”区域的物流服务水平进行分析。研究发现:LPI指标体系的内在逻辑具有一致性,能够有效识别不同国家或地区的物流服务水平及个体差异性;中国与“21世纪海上丝绸之路”区域国家间贸易额与各国物流服务水平的提升之间存在关联;在注重物流基础设施投资的同时,要关注物流服务相关标准及规则体系的对接。

In order to evaluate the rationality of the global logistics performance index(logistics performance index,LPI)and its application in practice,the involved countries on three ocean routes in the area of the 21st Century Maritime Silk Road are taken for example.The validity of the LPI is verified by applying the hierarchical clustering and correlation analysis and the logistics service levels in the above-mentioned area are analyzed accordingly.It is found that the LPI has inherent logical consistency,which can effectively reflect the logistics service levels of different countries or regions and individual differences.The rapid increase in the trade volume between China and the countries in the area of the 21st Century Maritime Silk Road would greatly enhance the logistic services of these countries and it is proposed that special attention should be paid to the compatibility of different logistics service standard systems when making logistics infrastructure investment overseas.
