ABSTRACT Based on regime theory and orchestration-intermediary theory on the interaction of international institutions, complemented with a revisionist realist perspective, this article proposes a theoretical model to examine the effectiveness of the G20 agenda. The theoretical model consists of weighing up a member state’s willingness and capacity to build a political coalition and technical support from relevant intermediary institutions on a G20 agenda, as well as the use of coercion or soft power pressure by the political coalition behind the agenda. Employing a case study approach, the article illustrates the theoretical process by examining (1) the Enhanced Structural Reform Agenda and (2) the green finance agenda at the G20 Hangzhou Summit of 2016. The article concludes that any real progress achieved on the G20 agenda in the post-crisis period requires the presence of all factors in the theoretical model and provides recommendations on improving the G20’s effectiveness based on the case studies.

G20议程与成员国国家层面政策的互动：提高G20有效性的理论模型

摘要 本文基于国际制度相互作用的制度理论和协调-中介理论，辅以修正主义现实主义视角，提出了一个理论模型来检验 G20 议程的有效性。理论模型包括衡量成员国在 G20 议程上建立政治联盟的意愿和能力以及相关中介机构的技术支持，以及议程背后的政治联盟使用胁迫或软实力压力。本文采用案例研究方法，通过考察（1）强化结构性改革议程和（2）2016 年 G20 杭州峰会的绿色金融议程来说明理论过程。
