This research investigates and reorganizes the concept and formation process of new research areas (NRAs), and discusses the science, technology and innovation (STI) policy for accelerating NRAs' formation. NRAs have no clear definition, and the concept is diversified. Then, this paper begins with working hypotheses that there are two types of NRAs driven by multi-discipline dynamics (bottom-up type) and social vision (top-down type). We reorganize the concept and formation processes with multi case studies. Next, foresight process and governance mechanism of NRAs on STI policy is examined. Finally, this paper concludes how the STI policy can control NRAs and enhance the social receptivity for the outcomes from NRAs.
