Abstract
This study provides qualitative evidence of impacts of technologies. Diverse impacts of technologies on society, economy, and quality of life are documented. Elaborated case studies illustrated the contribution of public sectors on the realisation of the impacts. The public sectors play significant roles in diverse ways. The studies show direct and indirect contribution of the public sectors. The public sectors directly influence on the realisation of impacts through (1) Promotions of basic research and (2) Flexible promotions of R&D in accordance with technological trends. In addition to this, indirect contribution, such as (3) Support to research infrastructures and (4) Promotion of impact realisation through coordinated Policies, are also significant. These four public measures cannot work effectively if implemented independently. The public sector should assess what is the major bottlenecks in the realisation of impacts, and launch a set of measures to help realisation of the impacts.
