This article theorizes the potential roles of the state in the urban commons through an analysis of a slum upgrading program in Thailand that employs collective forms of land tenure. In examining the transformation of the program from a grassroots movement to a “best practice” policy, the article demonstrates how the state has expanded from mere enabler of the commons to active promoter. In the process, the role of many residents has evolved from actively creating the institutions of collective governance—commoning—to adopting institutions prescribed by the state—being commoned. However, by comparing the work to two different groups of communities who work within the context of the policy, the article illustrates how active commoning can still take place in such contexts.

本文通过对泰国采用集体土地所有权形式的贫民窟改造计划的分析，对国家在城市公地中的潜在作用进行了理论分析。在考察该计划从草根运动到“最佳实践”政策的转变过程中，本文展示了国家如何从单纯的公地推动者扩展到积极推动者。在这个过程中，许多居民的作用已经从积极创建集体治理的制度——公有——发展到采用国家规定的制度——公有。然而，通过将工作与在政策背景下工作的两个不同社区群体进行比较，本文说明了在这种背景下仍然可以发生积极的共同化。
