英文摘要：

This work analyzes the ＂information isolated island＂ problem in E-government information resources sharing. From the economic point, the incomplete information repeated game model was proposed. The information sharing mechanism and condition were discussed based on KMRW theory. Furthermore, the stratagem of applying subsidy policy for information resources sharing was explored. The results show that the government should minimize the sharing cost, help to establish the long-term cooperation relationship among departments and use the information subsidy policy to promote information resources sharing.
