Governance research has been limited to literature reviews or case studies, and little quantitative analysis has been performed to examine varying patterns of governance mixture and their underlying variation. This article provides an important addition to governance research by mapping the terrain of governance mixture using quantitative data. The data were drawn from 96 departments in eight comparable district governments in Seoul, Korea. The results showed: first, all three governance modes – hierarchy, market, and network – existed in a combined form across all 96 departments; second, although all three governance modes were present, hierarchy remained the dominant governance mode across all 96 departments; and finally, the three governance modes were situationally mixed contingent upon the distinct departmental tasks. The implications of these findings are discussed.
