Policy Framework for Prefabricated Buildings in Underdeveloped Areas: Enlightenment from the Comparative Analysis of Three Types of Regions in China

Prefabricated buildings (PBs) are vigorously promoted for their many advantages. However, obvious regional differences exist in the development of PBs China, and underdeveloped areas significantly lag behind other areas. Regional “tactics” have a more direct effect on than national “strategies”. A targeted analysis PB policies China is lacking current research. Therefore, aim this study was to construct comprehensive policy framework help improve develop PBs. In study, we constructed three-dimensional based content method instrument theory. Through comparative 137 three representative regions, 547 codes were obtained, reliability validity tests completed. The results indicate that (1) should focus improving number rather accuracy early stages PBs; (2) mandatory instruments (MPIs) supplemented by incentive (IPIs) social (SPIs) balanced use various instruments; (3) adjust layout whole life cycle, stakeholders pay attention construction willingness developers demands consumers seek support operation maintenance stages, as well during demolition recovery stages. systematically analyzed different proposed an application strategy instruments, contributing improvement system narrowing gaps with respect
