In a polycentric urban structure, the commuting pattern which was traditionally directed from the suburban to CBD, is becoming more complex with increasing reverse- and cross-commuting activities. This paper is aimed to provide empirical evidence which validating the importance of utility-maximizing parameters, derived from the monocentric model, in the context of post-suburbanized polycentric urban region. It questioning to which extent of different residential mobility between municipalities could be linked to the variation of such parameters. Focusing on the frontier areas of Jakarta Metropolitan Area (JMA), Indonesia, each municipality within the region is treated as a Decision-Making Unit which intend to maximizing co-location between residential and employment uses. Using the data from the 2017 National Socio-Economic Survey (SUSENAS), the analysis was simply taken by comparing the aggregative-mean of income, housing-cost and transportation cost data from each municipal in JMAs periphery. The Data Envelope Analysis (DEA) was used for measure how these utility-maximizing parameters related with inter-suburban migration flows. The results show that housing cost is the only utility which still has significant impact in polycentric setting. Moreover, the area with lowest utility value tends to be the most efficient in attracting in-migrant. It implies that residential mobility within suburban areas does not motivated by lower housing or transportation cost, nor to get near to major employment location. Thus, workers heterogeneity and behavioral aspect may have played bigger role in residential mobility of polycentric urban setting.
