治理架构、国家诉求和机制响应:小岛国何以将全球气候问题诉诸国际司法OACHSSCD

The active engagement of small island developing states(SIDS)in international climate judiciary has emerged as a notable phenomenon in global climate governance.However,the United Nations Framework Convention on Climate Change,as the primary channels of global climate governance,have already endowed SIDS with institutional power,enabling them to exert considerable influence despite their limited national power.Why have SIDS,as beneficiaries of the existing climate regime,nevertheless turned to judicial mechanism?This article develops an analytical framework of"governance architecture-state claims-mechanism responses"to examine the drivers of this phenomenon from international,actor,and institutional levels.The findings suggest that the low levels of hierarchy and high functional heterogeneity of the global climate governance regime complex provides space for regime creation.While international judiciary mechanism,compared with other mechanisms,is better able to respond to SIDS' claim of accelerating process and broadening channels for climate governance.Consequently,SIDS increasingly regard international climate judicial mechanisms as an important institutional tool.
