Abstract: The collaborative platform on clustering applications for governments consists of six largcscale systems. The application and technique architectures of the collaborative platform were elaborated in this paper, and the major key technologies on the platform were also expounded, which include realization of many governments applications' scale integration and collaborative application, business model driven software development platform based on SOA, uniform resource management, and security improvement of Web services. The platform having been running shows that rural distrios and counties can build their own platforms based on the provincial platform to maximize the utilization of hardware, software resources and administrative resources of the provincial government collaborative platform; thus the planning of urban and rural e-governments' construction and maintenance is achieved, efficiencies of government affairs' administration and collaborative work are improved.
