| Abstract: | Fragmentation and specialization—two characteristics of governance—have increased the number and variety of actors involved in the governing process, which can influence policy outcomes and legitimacy. To date, studies on governance or policy networks usually focus on one policy field and one moment in time. In this article, we analyse the dynamic aspect, thus how governance networks change over time, and examine whether the fragmentation and specialization of the governance system is mirrored in the circulation of public officials. Our case is the urban governance system of the Paris region, which is characterized by high fragmentation along policy fields and territory. The data show that Paris is governed by three sub‐systems that largely correspond to the different territorial levels of governance, but also to different types of organizations. Generally, territorial fragmentation seems to be stronger than policy field fragmentation. This structure is quite stable across time. |
