ABSTRACT This article analyses the G20’s effectiveness-legitimacy nexus while undergoing a shift from club to network governance. Despite pitfalls, it is argued that the strategic widening of the G20 agenda, coupled with its more inclusive approach to a variety of topics within the work streams, carries potential for increasing its effectiveness and legitimacy. Analysing the working arrangements of the Development Working Group and Mexico’s participation (through AMEXCID) and other forms of engagement for G20 members – for example, the Voluntary Peer Learning Mechanism on the Implementation of the 2030 Agenda – the key claim of the article is that, beyond summitry, the G20’s effectiveness could better be assessed by the outcomes of its work streams and working groups, coupled with individual country efforts, which should thus receive more public attention as a means to counter criticism regarding weak legitimacy.

G20 发展工作组的有效性与合法性关系：墨西哥的观点

摘要 本文分析了 G20 在从俱乐部治理向网络治理转变的过程中的有效性-合法性关系。尽管存在缺陷，但有人认为，G20 议程的战略性扩大，加上其对工作流程中各种主题的更具包容性的方法，具有提高其有效性和合法性的潜力。分析发展工作组的工作安排和墨西哥的参与（通过 AMEXCID）以及 G20 成员的其他参与形式——例如，实施 2030 年议程的自愿同行学习机制——文章的主要主张是，除了峰会之外，G20 的有效性可以更好地通过其工作流程和工作组的结果以及各个国家的努力来评估，
