Research On PPP Model In Public Infrastructure Construction

In recent years,China's infrastructure construction is developing at an increasingly high speed.Our country also pay more attention to the public infrastructure construction.Urban public infrastructures are the products and service that are provided by the government departments through tax and other revenue.They are necessary for the citizens to live.Besides they supply the urban economic and social development and people's cultural life with basic protection.Urban public infrastructure construction belongs to the public product,so it stands to reason that it is invested by the public sector all the time.However,with the rapid advance of urbanization,a large number of urbanization of population transfer,urban infrastructure construction has couldn't keep up with the pace of The Times development.The needs of capital investment is increasing at a high speed,but government revenues are insufficient to meet the needs of the investment.On the other hand,for the nearly forty years of reform and opening-up,,the rapid development of social capital lays a solid economic foundation for the private business owners to participate in public infrastructure project.Under the action of market economy,some private business owners begin to have strong interest in investing in infrastructure.In such a social background,the government departments and the private business owners are in agreement on that PPP(Public-Pivate-Partnerships)has become an effective way to promote the reform of marketization of public utilities.Our country pays more and more attention on the PPP reform.Compared with other financing model,PPP model has more obvious advantages and wider range of application,so it becomes possible for us to bring in such new model in the infrastructure construction.The management experience that private businesses accumulated in the last few decades plays an important part in the field of infrastructure.The introduction of PPP mode can not only attract social investment,but also take advantage of their management,in order to speed up the construction of infrastructure to meet people's growth.The PPP model is based on the current social environment cause the attention of the whole society,analyzes the attributes of public infrastructure and the advantages and disadvantages of the PPP mode,through to the PPP mode inductive comb,detailing the PPP mode characteristics of various kinds of types.This paper argues that public infrastructure construction fund shortage and low efficiency use two aspects that the introduction of the necessity of PPP mode,financing,system,management,and practice four aspects that illustrate the feasibility of PPP mode,can make full use of this new mode in practice,the key lies in how to use this tool.Through the analysis of the present operation situation and existing problems,combining the United Kingdom,Canada,Australia,the three countries experience,summed up the completes the PPP should grasp the following points: one is the role transition of government departments,create good policy platform for social capital;The second is the perfect legal laws and regulations,and create fair operating environment for social capital;Three is to establish a performance evaluation and supervision and management mechanism,effective collaboration to lay the foundation for both sides;Four is to develop a reasonable profit and risk sharing mechanism,established the "by most can control the risk of one party to the principle ".With the application of PPP pattern practice deepening,hope for the top-level design of PPP pattern in China,this model rapidly popularized in our country.
