Abstract—Industries in Taiwan have developed for up to 60 years, but many industrial zones, pieces of industrial land or other related resources have gradually shown signs of decline, and manufacturers and factories have even gone bankrupt or transferred their production sites to other countries, which has caused the redundancy and neglect of the industrial land. Most of these sites were originally located in the urban fringe, but are, due to the citiesˇ expansion and alteration, now gradually adjacent to them. Civilians and environmental groups are considera-bly concerned about the impact of "brownfield" on their sphere of life. Accordingly, the study summarizes the relevant research and data regarding brownfield, and constructs the evaluation indicators of the regeneration of brownfields through empirical research of FORMOSA CHEMICALS & FIBRE CORPORATION. The purpose of the study is to offer indicators, in multiple aspects, for assessment and inspection, in hope of being a reference to the relevant policy and studies of the assessment for activation and regeneration of brownfields, so that the brownfields in cities can play its due value.
