The concerns of possible impacts of vertical-developed cities have long discussed for several decades. Since the 1980s, in order to improve the urban environment and increase open spaces, the Taipei City Government granted additional floor area bonus as incentives in exchange of the private developers providing privately owned public space (POPS) for public use. Nevertheless many studies identify that the openness and the publicness of most POPSs are lower than expected. However, other concerns such as the possible external costs of the urban environment i.e. the decline of public service quality, more energy consumptions, increasing residential density, and skyline destruction derived from the additional floor area bonus as incentives for POPS are still to be studied. Early local research regarding the POPS usually focused on the usage of such space, and has given advices on design details. There is a lack of discussion about the impacts on the social behavior of residents by the POPS. Hence, this paper will discuss the possible impacts of the POPS on the social interactions（social relation. We will conduct questionnaire survey and field studies at the selected communities with more POPSs in Taipei. The research results will expect to gather some information about how can POPS benefit residents daily life at the community level and provide policy feedbacks on future POPS in Taipei.enprivately owned public space (POPS)People-environment fitsocial connectionArticle3061-3074
