FACTORS AFFECTING LOGISTICS SERVICE QUALITY IN INTERNATIONAL TRADE: A SYSTEMATIC LITERATURE REVIEW

Abstract

Logistics service quality (LSQ) plays a vital role in supporting the efficiency and competitiveness of international trade. Although numerous studies have examined this issue, comprehensive syntheses of the factors affecting logistics service quality in international trade remain limited. This study aims to identify and synthesize the key factors through a Systematic Literature Review (SLR) approach. Articles from leading databases such as Emerald, IEEE Xplore, SpringerLink, ScienceDirect, Google Scholar, and Taylor & Francis, published between 2021 and 2025, were analyzed based on rigorous inclusion criteria. The results identified five main categories: capabilities (36%), operational performance (31%), regulations (18%), customer relationships (8%), and costs (7%). These findings provide a conceptual foundation and strategic insights for the sustainable improvement of logistics service quality.
