Abstract

Since the 1990s, regional trade agreements (RTAs) have increasingly developed into networks. While some studies focus on the impact of individual RTAs, few examine the combined effects of RTA depth and breadth or the influence of RTA networks on trade. This study uses a gravity model and global RTA data (2010−2021) to analyze how RTA network centrality affects exports. The findings show that RTA network centrality positively affects exports by fostering technical progress and enhancing comparative advantages. These effects are stronger for countries with stable hub status, a larger number of trade agreements with destination countries, and closer geographical proximity.
