Electronic government (e-government) procurement is one of the most important activities in China. The paper consists of three parts. First, the paper introduces current situation of China’s e-government procurement system which includes the overall technical level, application level, and the existing problems. Based on the problem brought forward from the first part, the paper considers that a better solution is to apply business component theory and business component framework in the construction of e-government procurement, as it can solve the problems that block the develop- ment of e-government procurement in a more convenient way. The paper constructs the Business Component (BC) framework for the e-government procurement, analyzes the superiority of BC framework and describes a methodology for the application of BCs in e-government procurement. The paper utilizes semantic model for workflow by using ontology modeling tool Protégé, uses ontology model database to store and manage workflow model, and builds a permission-based and user-involved workflow. At last, the paper takes public bidding, a main e-procurement method in China as an example and uses Appfuse and Osworkflow to prove the validity of the framework and methodology
