This special section analyzes the variety of recursivity in transnational regulatory governance. We conceptualize recursivity as a complex cycle through which addressees’ response to transnational rules continuously feeds back into the rulemaking process and triggers rule revision. In the introduction to the special section, we emphasize that recursivity varies across governance organizations and governance fields and develop an analytical framework to capture this variation. We also propose a typology of recursive governance organizations. Finally, we preview five case studies included in the special section and summarize their key findings and conclusions, with particular attention to the implications for accountability and legitimacy.
