| Strengthening water pollution prevention and urban sewage treatment are listed as the key content of environmental management during the “13th Five-Year Plan” period.At present,the gap between China’s sewage treatment capacity and high-quality development is large,and the demand for sewage treatment in market development is still large.Based on the rapid development of wastewater treatment projects in water companies,the financing needs of sewage treatment projects have increased dramatically.However,the sewage treatment project of the water enterprise has problems such as single financing mode and high financing cost,which restricts the construction progress and service capacity of the sewage treatment project.As an important water enterprise in XZ City of Jiangsu Province,XS Enterprise also faces problems such as solidification of financing mode and high financing cost in the construction of the second phase of the sewage treatment project in Xincheng District.The focus is on minimizing construction costs,including financing costs.The choice of financing mode for the second phase of the new urban sewage treatment project is not only related to the success or failure of the project construction,but also affects the long-term development of XS enterprises.Therefore,it is necessary to carry out cost analysis on the financing mode of XS Enterprise New City Sewage Treatment Phase II project,make financing mode selection that meets the minimum cost,better complete the sewage treatment project,and break through the financing bottleneck of XS enterprises.Firstly,this paper combs the research status of water enterprise financing,and based on the theory of public goods,urban water theory and financing theory,combined with the actual situation of XS enterprise sewage treatment project,analyzes the current situation of project financing and financing environment.Compare the advantages and disadvantages of current financing models.By estimating the project’s capital demand and the financing model and financing amount available in the previous period,the limitations of the current financing model of the sewage treatment project are analyzed.Secondly,based on the principle of financing mode selection of wastewater treatment project,based on the principle of minimizing cost,this paper clarifies the target selection of project financing mode,starting from three key indicators: initial investment ratio,sewage treatment rate and financing cost rate.The three financing modes of the sewage treatment project—the fiscal construction model,the BOT model and the PPP model—are analyzed and measured.After comprehensive consideration of various factors,it is found that the PPP financing model meets the cost minimization standard and has strong application value.Furthermore,from the four aspects of investment demand,financing channels,decision variables andconstraints,the cost minimization financing model of water environment management project is constructed,and the conclusion of the paper is verified.The PPP financing mode is the choice that meets the cost standard.Finally,this paper focuses on how to make the PPP financing model operate in an orderly manner,and ensure that the project construction is delivered on time,and proposes the safeguard measures for the smooth operation of the financing mode of the XS enterprise wastewater treatment project. |
