Abstract:“Convergence Science” is a new paradigm of scientific research based on multi-disciplinary integration to solve grand problems, which is considered as a new opportunity for human beings to address major economic and social problems. Promoting “Convergence Science” means the fundamental change of scientific research ecology, one of the most basic aspects is the open sharing of data. Based on the basic characteristics of “Convergence Science” as a new paradigm of scientific research, this study puts forward new requirements of “Convergence Science” in terms of basic data, such as the whole disciplines, the whole processes and the full panorama, and then introduces the successful practice of open data supporting “Convergence Science”. Finally, it looks forward to the future prospect of promoting “Convergence Science” with “open data”.
