The purpose of this study was to examine the impact of Gross Domestic Product (GDP) and Logistics Performance Index (LPI) on international trade of nations across each continent and worldwide. Secondary data collected on 142 countries-37 Asian, 41 European, 41 African, 3 Oceania, 14 Middle East, 11 North American and 9 South American-were analysed across the years 2007, 2010, 2012, 2014, 2016, and 2018. Panel regression technique was applied and the random effect (RE) model was chosen based on the results of the Hausman tests and Breusch-Pagan Lagrange Multiplier test. The findings revealed that the LPI has a positive relationship with net exports globally and specifically within the continents of Asia, Europe, and Oceania. Moreover, while the GDP appears to have a significant negative impact on net exports, specifically within Asia, in contrast, countries in Oceania and the Middle East present a positive relationship. Also on the African continent, GDP has a significant negative impact on the net exports. Findings provide a holistic picture of the impact of LPI & GDP on net exports, which will assist governments in the formulation and revision of its strategies and policies to expedite the growth of exports and in turn, the economy. This study was the first of its kind to explore the impact of GDP and LPI on international trade of nations across worldwide.
本研究旨在探讨国内生产总值（GDP）和物流绩效指数（LPI）对各大洲和全球各国国际贸易的影响。使用面板回归技术，根据豪斯曼检验和布雷施-帕甘拉格朗日乘数检验的结果，选择了随机效应（RE）模型。本研究收集了 142 个国家的数据（亚洲 37 个、欧洲 41 个、非洲 41 个、大洋洲 3 个、中东 14 个、北美 11 个和南美 9 个），并对其进行了分析，时间跨度为 2007 年、2010 年、2012 年、2014 年、2016 年和 2018 年。研究结果表明，LPI 与全球净出口以及亚洲、欧洲和大洋洲等各大洲的净出口呈正相关关系。此外，虽然 GDP 似乎对净出口有显著的负面影响，特别是在亚洲，但大洋洲和中东国家的 GDP 与净出口呈正相关关系。此外，非洲大陆的 GDP 对净出口有显著的负面影响。研究结果提供了 LPI 和 GDP 对净出口影响的全貌，这将有助于政府制定和修订其战略和政策，以加快出口增长，进而促进经济增长。本研究首次探讨了 GDP 和 LPI 对全球各国国际贸易的影响。
