Current global economic governance is at a time of major rebalancing in world economic weight，and is experiencing different degrees of creation，rebuilding and reconstruction. The old governance framework in relevance of the Bretton Woods institutions and G7，are being replaced by new avenues of coordination and discussion. At the global level，as the most powerful platform，the G20’s reform after 2012 mainly focus on two aspects：one is continuing to push forward the reform of the IMF and WB’s governance structure，and enhancing the representativeness of emerging markets and developing countries；Second，through the continuous improvement of “troika” mechanism and agenda orientation，the G20 is transforming itself to a long-term economic governance mechanism. At the regional level，TPP and TTIP both made significant progress，and may produce significant influence on the patterns and rules of future international trade. The future global governance mode tends to be in a collaborative way of regional and global mechanism. China needs to actively seek more involved in global governance，and to speed up the reform of global governance system based on the platform of G20. At the same time，it is necessary for China to promote regional economic integration and change the unfair and unreasonable arrangement in current global governance system through multilateral，regional and bilateral cooperation，and to encourage the innovation in the global economic governance.
