This article illustrates the concept of supply and demand network of enterprises with multi-function and opening characteristics(SDN) and designs the selection process of the general contractor for subcontractor in the SDN environment, which can highlight the important influence of the subcontractor selection for a successful project completion.The SDN characteristics of global networks, multi-functions, fully opening and dynamic stability are discussed.Based on this, influence factors and principles for the establishment of selection index are analysised.Then, the hierarchy structure model for construction subcontractor selection is established.A method of combining AHP with DEA is proposed to judge the relative efficiency of each subcontractor.Finally, it realizes the comprehensive judgment of subjective and objective factors to consider the weight and the relative efficiency of each subcontractor, which could improve the reliability of construction subcontractor selection.
