Longitudinal Features Extraction in International Logistics Performance Index

The importance of the logistics performance of companies, regions and countries to support decision-making is universally recognised, covering the rationalisation of supply chains, the optimisation of inventory management and promoting global collaboration. Efficient logistics integration with innovative technologies is crucial for the prompt delivery of materials and components, increasing the speed and effectiveness of innovation processes and, consequently, the performance of organisations. The Logistics Performance Index (LPI) is an index created to assesses global logistical performance by measuring factors such as the quality of commercial and transport infrastructure, the ease of customs procedures and the efficiency of customs clearance, among other aspects that influence the transnational flow of goods. This study examines the robust correlation structure between LPI indicators over several years. Our results confirm the LPI as a longitudinal latent variable, characterised by its indicators, demonstrating excellent internal consistency. This consistency underline the reliability of the LPI for measure global logistics performance of countries. Thus LPI can be recognised as a valuable measure of countries international logistics efficiency, and can be used in practice as a tool for business and politics, guiding strategic decision-making and improving the cost-benefit ratio and competitiveness of organisations.
