Study On Priority Evaluation Of Private Capital Investment In Transportation Infrastructure Construction Project Under PPP Financing Model

Nowdays,transportation infrastructure needs is enormous with the rapidly development of economy in china,but the government limited financial strength is insufficient to accelerating the process of transportation infrastructure construction,while private capital willing investment to the transportation infrastructure construction project with the extra capital at the same time in order to gain more profits.In such a big background,it is very important that combined with the private sector and public sector to financing and management the transportation infrastructure construction.Transportation infrastructure construction projects have a different financing way,but PPP(public private partnership public-private partnership)financing mode suitable for application especially between the public sector of government and private capital financing.Because of the development of PPP financing mode in china was so short so that chinese government needs through the legislation to support all kinds of the PPP financing model.In addition,because of private capital in the capital stock is not infinite,can not investment of all potential transportation infrastructure construction projects,shall be carried out under certain constraints.Besides,to invest in transportation infrastructure construction projects,which has so many problems such as huge investment,long payback period of investment,including uncertainty index,more easily affected by national economic policies and so on.So,it is become an urgent problem that how to Scientific and reasonable evaluation a transportation infrastructure construction projects under PPP financing model before investment.While it is an effective way to solve the problem of investment potential transportation infrastructure construction projects through priority evaluation,and then according to the its strength and enterprise actual resources choice the appropriate project to implementation after identify the project priority order.This paper is study on priority evaluation of private capital investment on transportation infrastructure construction project under PPP financing mode,to provide a scientific evaluation decision methods for investment management decisions maker.This article mainly from the following several aspects:Firstly,briefly introduced the background of private capital investment in transportation infrastructure construction as well as the scholars at home and abroad related research.;Then,summarizes the birth of the PPP financing model,connotation and the basic structure and characteristics.In addition,define the concept of private capital and transportation infrastructure,analysis the realistic conditions of the PPP financing model applied to transportation infrastructure construction investment.Thirdly,collect related evaluation index by refer to a large number of relevant references,then asking experts and scholars to finishing and modification the collected indexes so that can establish a scientific and reasonable priority evaluation index system for private capital investment in transportation construction project under PPP financing mode.Except that,selection the IAFAD(Improved analytic hierarchy process ?fuzzy comprehensive evaluation method,?the accurate value method,?data envelopment analysis method)integrated comprehensive evaluation model through the approach of comparative literature to calculation priority.Finally,several potential investment projects instant analysis at the end of this paper is given to show the feasibility of this evaluation model and provides a decision-making reference for private investor investment in transportation infrastructure construction under PPP financing model.
