Research On Risk Sharing Of PPP Projects In Chatacteristic Towns

Since the country announced the first and second batches of characteristic towns,characteristic towns have set off a nationwide construction boom.How to continue to build characteristic towns steadily is still one of the issues that need to be considered in this construction boom everywhere problem.At the same time,the PPP model has been developing steadily in China and has been successfully applied to various infrastructure construction works.Combining the PPP model with characteristic towns is by no means unfounded,but is a practical approach to solving difficulties of characteristic towns and reduce the government financial pressure.Therefore,in order to better promote the integration of characteristic towns and the PPP model,it is particularly important to solve the problem of risk sharing among the participants in the characteristic town projects under the PPP model.Based on this situation,this article analyzes the risk issues from a third-party perspective based on knowledge of risk management,and further studies the risk sharing issues in characteristic township projects under the PPP model.First,on the basis of consulting a large amount of relevant literature and actual cases,this paper uses the WBS-RBS method to identify the risks of characteristic town projects under the PPP mode,and constructs a risk factor coupling matrix to determine the full life cycle of the characteristic town projects under the PPP mode.List of risk factors;secondly,the risk sharing process of characteristic town projects under the PPP model is designed,the main participants of each risk factor are clarified,and by participating in the construction of a rough set model,the participation in the shared risk calculation of characteristic town projects under the PPP model is calculated party's risk sharing ratio.However,in the actual construction process of the project,there are often some unforeseen risks in the early stage.For this reason,this article constructs a bargaining game model with incomplete information to share the risks of these unidentified risks in the early stage.Finally,this article uses Guangxi Jin Xiu Yao Medicine origin of Kang Yang characteristic town as an example,and the rough set and game theory model are creatively applied to the actual case of the characteristic town project under the PPP mode,which quantitatively solves the problem of risk sharing of the characteristic town project under the PPP model.Through the study of this paper,the following conclusions can be drawn:(1)The characteristic town project adopts the PPP model,which can effectively solve the problem of insufficient funding of government departments;(2)The risk identification of the characteristic town project under the PPP model through WBS-RBS,comprehensively identify the risks faced by the project construction,and build a risk index evaluation system for characteristic small town projects under the PPP model;(3)Combine case studies with Guangxi Jin Xiu Yao Medicine origin of Kang Yang characteristic small town project,build a rough set and combine game theory Risk sharing model,calculates the risk sharing of the shared risks faced by the project,and gives a certain analysis of the calculation results of the sharing ratio.
