%X As a scientific infrastructure, scientific data sharing platform can promote primitive innovation of science and technology, and improve national scientific and technological competitiveness. This paper reviews the initiatives aiming at promoting China' s scientific data sharing activities in recent years, indicates major problems in the process of its implementation, and explores the focal point of future progress and working method of scientific data sharing in aspects of ideas, data integration, and platform building. Taking the practice of Data Sharing Network of Earth System Science (DSNESS) as an example, the paper examines scientific data sharing alliances; implementation of initiative service; combination of scientific research and data sharing activities; data agents; powerful scientific data search engine; promotion of document and information services, and etc. As a result, DSNESS has integrated about 7TB scientific data and established one head- center, one authentication- center and 12 sub- centers that form a distributed data sharing network platform. Through this platform, we have provided different data sharing services for more than 20,000 users.
