Abstract
After 1990's, technology foresight has been conducted by many countries of OECD members, Asia and South America. These countries have developed the methodologies of technology foresight by their own aspects to meet their original social and political needs. Aiming to obtain an overview of technology foresight, this paper examines objective, methodology and subject area of technology foresight in the world. The objective of technology foresight is not only to contribute to science and technology and innovation strategy planning, but also to establish a knowledge base related to science and technology and innovation strategy as a learning tool. Furthermore, a bibliometric analysis of Delphi method, scenario-planning and technology roadmapping has found that the numbers of publications of each methodology have increased, and these subject areas are different by methodology such as health and medicine for Delphi method, environment and energy for scenario-planning, and electricity and semiconductor for technology roadmapping.
