报告摘要

Objective: To investigate the impact of geopolitical shocks on international trade flows by examining an augmented gravity model with bilateral trade data from 1948-2021.
Method:
- Constructed a gravity model with over 4 million observations across 59,049 country pairs.
- Used variables: country income levels, geographic distance, language/religion/colonial ties, trade agreements, and a measure of geopolitical alignment based on UN voting patterns.
Key Findings:
- Geopolitical Alignment: Has a statistically insignificant effect on trade flows overall, but the sign varies: negative for developing countries, positive for advanced economies. The economic significance is minimal compared to other factors.
Other Determinants:
- Real GDP per capita in both origin and destination countries positively affects trade.
- Geographic distance negatively affects trade due to higher trade costs.
- Common language, religion, and historical ties boost trade. Countries with trade agreements (FTA, GATT, WTO) see increased trade volume.
Robustness: Findings remain consistent when accounting for outliers, time-varying specifications, or alternative country groups (e.g., advanced vs. developing economies).
Conclusion: Despite recent geopolitical shocks and concerns about deglobalization, international trade remains resilient, and globalization continues to drive economic integration and prosperity.
