| PPP(public private partnership),also known as PPP mode,is the cooperation between government and social capital.It encourages private enterprises,private capital and government to cooperate and participate in the construction of public infrastructure.It is the most suitable financing,delivery and management mode for large and medium-sized public projects such as infrastructure,public utilities,urbanization and natural resource development.It has been widely used in the world,and has been valued and rapidly developed in China.The introduction of PPP model in the field of ecological engineering eases the burden and pressure of the government’s financial expenditure in the field of environmental governance.By improving the enthusiasm of social capital,we can broaden the investment and financing channels,and give full play to the professional technology and innovation advantages of social capital.However,in the process of participating in environmental protection PPP projects,due to the large scale of PPP projects,unstable expected earnings,long project recovery cycle,uneven financial strength of the project area,cautious attitude of commercial banks and other traditional financial institutions towards PPP project financing,it is difficult to achieve the financing objectives of PPP projects.Therefore,enterprises have to carry out large-scale financing Endowment.The actual situation of enterprises’ financing will be affected by many aspects such as internal and external environment.Therefore,the choice of enterprises’ financing structure also indirectly determines whether enterprises can participate in PPP project construction better.On the basis of combing the relevant theories of PPP mode,this paper studies the development process and current situation of PPP at home and abroad,PPP financing mode and the current situation of ecological environment industry,corporate financing mode and corporate capital structure.Through the analysis and comparison of financing methods of listed eco engineering enterprises,it is concluded that eco engineering enterprises have entered into a rapid development period,but there are many conclusions,such as large financing risk,high cost and single channel.At the same time,based on the influence of external and internal factors on financing mode,this paper establishes multiple regression model,tests the influence of internal and external factors on internal financing,bank credit financing and equity financing of the company,and concludes that enterprise scale and profitability have significant positive influence on the capital structure of listed Eco engineering enterprises;internal resource capacity and solvency ofenterprises There is a negative correlation between them and the capital structure,and the conclusion that the growth ability and the asset guarantee value have no significant influence on the capital structure of listed eco engineering enterprises.In the end,this paper takes Dongzhu ecological environmental protection Co.,Ltd.as an example to analyze the current financial situation of the research object,PPP project situation,cash flow,financing situation,combined with the analysis and comparison of the internal and external environment of the enterprise,through the establishment of the financing decision AHP model to select the financing scheme.It is concluded that the financing order of Dongzhu ecology is bond financing,bank loan and trust financing.It can be used for reference for other enterprises. |
