金砖扩员对全球贸易格局及中国的影响OACHSSCD

To analyze the dual impact of the historic expansion of the BRICS on the global trade system and China,this paper examines the overall pattern changes after the inclusion of six emerging economies,namely Saudi Arabia,Iran,Egypt,Ethiopia,the United Arab Emirates,and Indonesia.It is found that the expansion has significantly enhanced the influence of the BRICS in global affairs,promoting the evolution of the global trade governance system towards greater balance.Meanwhile,based on the common demand of the new members for reducing reliance on the US dollar,the expansion will substantially accelerate the process of de-dollarization in settlements.For China,the rich energy resources of new members will help diversify China's energy import channels,improve the trade structure network,and continuously expand the overall trade scale.Moreover,BRICS system will enhance the collective voice of the Global South,thereby laying a more solid foundation for China to participate in formulating future global economic and trade rules.However,opportunities coexist with challenges.While the expanded BRICS mechanism enjoys growing potential,it also faces new tests in internal coordination and the external environment.The objective differences among member states in terms of economic development stage,industrial structure,and policy orientation may cause obstade in the advancement of specific projects and macro policy coordination.At the same time,the growing strength of BRICS may trigger vigilance from traditional developed economies,which may create external obstacles for the deepening of cooperation.Therefore,how to strengthen internal integration and respond to external pressure after the expansion will be the key to the continuous development of the BRICS mechanism.
