Research On Financing Problem Of Sponge City Project PPP Model

In order to ameliorate the imbalance of urban water ecological caused by traditional urban constructing methods and solve the problems of frequent floods or water shortages in cities,China proposed to promote low-impact development models on the bases of foreign experience.The LID model,which is a kind of the sponge city meeting the natural ecological characteristics by making full use of rainwater resources to repair urban water cycles.Meanwhile,in the progress of advocating the PPP model for the introduction of social capital so that the benefits of their capital,technology,and management can be used to improve project construction efficiency.Despite of the strong support from center government,the PPP model for the construction of the Sponge City project by local governments still faces many problems and risks in actual.Especially in terms of financing,there are problems such as imperfect system and mechanism,single channel and unreasonable structure.It is a real and urgent need to take measures to optimize the financing environment and more solve the problem of huge sources of construction capital reasonably and conveniently.At present,many domestic projects are focused on the construction of the Sponge City Project or the application of the PPP model in Sponge City projects.Research which focused on the financing of the Sponge City Project using PPP model is slightly insufficient.Therefore,it is realistic and urgently needed to analyze the financing of the PPP model of the Sponge Urban Project,and to explore how to optimize the financing environment and solve the difficulties of financing huge construction funds.In the background of the new normal China's economy and further promoting the supply-side structural reform,this paper use literature research methods,logical induction methods,comparative analysis methods,case analysis methods,etc.From the current situation of the financing in sponge city project and the characteristics and advantages of PPP model,this paper explain the feasibility of the sponge city project adopting the PPP model for financing.Then the main problems in the financing of the sponge city project PPP model are analyzed.Combined with H city project case,this paper proposed some practical suggestions from the view of laws and regulations,operation modes,financing structures,benefits and risks,and exit mechanisms,which are expected to provide some inspiration for alleviating the financing difficulties of sponge city project using PPP model in local area.
