With the speeding up process of global economic integration,supply chain management-integrated management model has been widely used in various fields.In the construction industry,with the projects move towards large-scale and complexity, supply chain management and supply chain risk management has attracted more and more attentions of construction enterprises.In China,the supply chain risk management research of construction enterprises is still in its early stages,but,in the face of the rapid development of China’s construction industry,as well as domestic and international market demand,If China’s construction enterprises want to gain more market shares and achieve sustainable development,they should must pay more attentions to the study of supply chain risk management.This study is just based on this background,hoping that through the studying of supply chain-related theory we can identify the supply chain risks and assess the risks, ultimately advance some relevant suggestions.First of all,this paper summaries the domestic and foreign studies of supply chain of construction enterprises,and the supply chain risk management theories and also some related theories are discussed,on this bases,this paper advances the methods of identifying the risks of construction enterprises and the categories of the supply chain risk of construction enterprises,combining of the categories of the risks of construction enterprises and the characteristics of construction enterprises,this paper further establishes the risk evaluation index system of the supply chain of construction enterprises,this evaluation index system contains seven aspects,they are:the risks of the external environment,management risks,the risks of system frame,supply risks,technical risks,finacial risks,information risks,and this is a valuable exploration for the supply chain risk management of the construction enterprises.The establishment of the evaluation index have reflected overall,systematic and scientific principles,then this paper chooses BP neural network to design and caculate in MATLAB.Last,this paper chooses four specific supply chains of some construction projects as the examples and evaluates the supply chains’ risks according to the evaluation index system advanced above then points out the risk situation of this supply chain.From the point of advancing the management level of supply chain risk of construction enterprises of China,according to the evaluation index system of construction enterprises of China,this paper advances some relevant suggestions,hoping that they can make some contributions to the supply chain management of construction enterprises.
