一种政务网信息交换与共享新模型

针对电子政务建设过程中出现的政务信息交换模型进行分析，在此基础上，提出新的政务信息交换C-D模型有机地整合了集中式、分布式和目录服务模型所具备的优势，并结合政务网络的特点，利用复杂网络理论对C—D模型的有效性进行了论证。该模型中的目录信息临接交换技术能够有力地提高各政务部门之间信息交换与共享的效率和可靠性。

A New Model for E-government Network Information Exchanging and Sharing

On the basis of analyzing the traditional E-government information exchanging and sharing model, we present an exchanging model for E-government information resource called C-D model （ Centered and Distributed model）. The model is integrated and extended from the centralized, distributed and directory service mod- el. Combining the feature of E-government network, this paper proves the validity of the C-D model based on complex network theory. The adjacent exchange of directory information in this model can effectively enhance the validity and reliability of information exchange among government departments.
