This article investigates whether, in the interaction between the public sphere and heritage conservation policies, the subjective meanings of conservation per se are dynamically modifiable or whether government responds to conscious changes in development policy. By exploring conservation practice and property development restrictions in Taiwan, three types of conservation systems have been articulated: remedial measures for those landowners whose development rights are limited by heritage conservation; acquiring of reserved land for public amenity under government fiscal crisis; and development capacity games under neo-liberalism. These types of development exercise have affected public sector heritage conservation and revitalized heritage, but with the current development system, the exercise has turned into a form of neoliberal urban power game and is an obstacle to conservation. The meanings of heritage conservation is dynamic, envisaging the constraint, and reconstruction of public sector heritage conservation is particularly important. In addition, the way authority sophisticatedly modifies its governance responding to structural changes is also urgently demanding.
