In globalization’s era, the sustainability of a region is inseparable from the in-depth and close economic and trade cooperation of intra-regional countries to achieve complementary advantages, intra-regional and extra-regional positive economic cycles, and stable and balanced benefits distribution. For Asia-Pacific countries, the lack of deep cooperation in the past has affected their sustainability, but this can be made up for by the RCEP agreement aimed at achieving intra-regional trade liberalization. We adopt the Global Trade Analysis Project (GTAP) simulation analysis method to quantitatively analyze the impact of changes in macroeconomic and international trade indicators of several intra-regional countries after implementing the RCEP tariff reduction and exemption on the RCEP. Simulation results and comparative analysis based on international relations prove that despite the interference of trade benefits conflicts and international political factors, the RCEP can still exist in long term, and effectively promote regional economic integration and sustainability in the Asia-Pacific region. It is also a development opportunity for intra-regional countries and can also be used in the context of globalization providing references for integration and sustainability in other regions.
