Risk Allocation Research Towards PPP Mode In Urban Rail Transit Construction

Risk allocation is the core issue for both negotiators in PPP project concerning urbanrail transit construction,and the essence is the different cognitive towards key riskfactors in the whole project life cycle, as well as the shared risks cannot really reflecton the total income obtained. All these concerns have something to do with thedeficient research on risk allocation for PPP parties, which make our topic necessary.This thesis systematically studies on risk factors which influence the PPP project inthe urban rail transit construction. The paper adopts approaches for risk identificationsuch as WBS, Delphi method, cause and effect diagram, check sheet approach and soon, identifying key risk factors which influence the whole project; then the thesisestablishes the risk allocation theoretical model and distribution framework for urbanrail transit construction with PPP mode. Based on the works above, risk allocation isconducted under the criterion- Efficiency Priority, with the key risk factors allocationmatrix followed.At the same time, Firstly, this thesis presents an over-all introduction about PPP modedevelopment, analyzes risk management and control situations at home and abroadand points out the current research limitations. Secondly, it summarizes the basicfeatures of rail transit construction and unfolds mainly research on applicability ofPPP construction mode; Thirdly, the comprehensive definition, existing theories andexisting models of risk allocation are provided, then the thesis tries to build novel riskallocation model for urban rail transit construction according to analysis of riskallocation effect and impact factors; Finally, it propose the allocation mechanismbased on risk allocating and re-allocating linkage.Subsequently, this thesis analyzes the PPP project-No.5 subway in Shenzhen,including the sharing of key risks and so on, Since then,this thesis in turn extends tothe engineering practice,expounding to the actual projects of PPP mode in urban railtransit construction about how to identify risks and risk allocation, by brieflyintroducing a variety of general contract and different regulation by local governmentabout risk allocation, it proposes risk allocation framework and specification due todifferent stages in the whole project life cycle.At last, this thesis introduce a risk allocation case of No 5 subway in Shenzhen, taking a comprehensive introduction with the main difficulty, responsible measures, riskallocation mechanisms, implementation process and the results of risk allocation. Thetheory and mechanism of risk allocation of PPP mode in urban rail transit constructionare certified.
