The Dynamics of the Global Arms Trade Network: States’ Stability and Instability

This study identifies security-related factors affecting the formation of the global arms trade network. This empirical analysis using a quantitative approach includes data from multiple sources (the Global Peace Index, Political Stability Index, Democracy Index, Global Terrorism Index, Fragile State Index, and military expenditure as a percentage of GDP) and multiple states analyzed using the ERGM. Arms trade data related to six attributes of states representing their (in)stability is collected and analyzed for 2012-2018. Our findings are as follows: (1) states with greater internal stability import more arms, which affects the formation of the global arms trade network; (2) states with greater external instability import more arms, which also affects the formation of the global arms trade network. This study makes two academic contributions, as follows. First, we analyze factors that form the global arms trade network from a holistic or systemic perspective. Second, we analyze those factors empirically and statistically from a security perspective.
