Abstract: Starting from the “open access” at the beginning of this century to the current “open data” and “open science”, the “open movement” featuring knowledge sharing has continued to develop in depth and with ever-increasing popularity. Its significance lies not only in the openness and sharing of knowledge, but more importantly, it will change the paradigm of scientific research and the ecology of knowledge exchange, upgrade the capability of technological innovation, and promote economic and social development. This paper, by way of combing and analyzing the global knowledge openness movement in the past two decades, discusses the significance of research data management in promoting knowledge openness and sharing, and puts forward four suggestions: first, to increase publicity and enhance awareness of open sharing; second, to formulate relevant policies and promote open scientific development; third, to consolidate various resources and build digital infrastructure; and fourth, to cultivate specialized personnel so as to enhance data management.

Key words:  Open access, Open dat, Open science, Open innovation, Research data management
