Research On Game Model Of Commercial Complex Project Risk Sharing Under IPD Mode

In recent years,the real estate industry has witnessed a boom in the development and construction of commercial complex,which,however,is characterized by large investment amount,long development cycle and high operational difficulty.Under the traditional delivery mode,each participant lacks the spirit of cooperation,and many problems such as project information asymmetry and frequent design changes exist.In addition,with the increasing number of participants in the commercial complex project,their relationships between each other also need to be improved urgently,and the traditional delivery mode cannot meet the higher requirements already.To solve such difficulties,this essay introduces the Integrated Project Delivery(IPD)mode into the project management of commercial complex,so as to provide a reference for solving the problem of risk sharing of commercial complex projects under IPD mode.IPD model has been successfully applied in many foreign countries,and though less in China,many scholars at home are dedicating to researching IPD mode.From the perspective of private investors,this essay studies the risk sharing of commercial complex projects under the IPD model.Based on existing results,this essay first identifies risk factors in the whole life cycle of commercial complex projects under IPD mode,and deeply analyzes the manifestations of each risk factor.On this basis,the method of questionnaire is utilized to have access to ideas about the occurrence frequency of each risk factor and their harm degree,and to calculate and analyze their levels of importance,and the results show that the risk importance levels related to project participants are generally high while those of the IPD mode and other related mechanisms are relatively low.Secondly,the essay constructs the three-party completeinformation static game model,and analyzes the risk factors that need to be shared by the owner,the contractor,and the consultant,or two of them and even three parties together.Moreover,try to combine quantitative analysis and qualitative analysis to establish a bargaining game model and a three-party dynamic game model under complete information to carry out the second risk sharing.Finally,taking the risk sharing of a commercial complex project under the IPD mode in Xi 'an city,Shaanxi Province as an example,this essay analyzes and calculates the risk sharing ratio of all parties,verifies the risk sharing process proposed in this essay,and makes corresponding prevention suggestions for different participants according to their results of risk sharing.The empirical analysis results indicate that certain theoretical significance and pra ctical value can be found in the study of the essay on risk sharing of commercial compl ex projects under IPD mode,which promotes the development of IPD mode in China,a nd provides a reference for the risk sharing of similar projects in China.
