| In recent years, Chinese economic level of development, is in a critical period of transformation and development, economic development and further accelerate the pace of urbanization of our country, the scale of urbanization has been improved to a great extent. During the period of 12th Five-Year, China's urbanization rate has exceeded 50%, the overall step into the urban social stage, the urbanization of the regional gap is gradually narrowing, urban agglomeration of the carrier function is increasingly perfect. But with the rapid development of China's city construction, facilities, communications, gas, electricity and other public foundation foundation for city development provides a great demand, more and more narrow space city, more and more valueable, the increasing development of city public infrastructure capacity demand and speed of development of city infrastructure and rationality the contradictions have become increasingly prominent. In this case, it can effectively guide the new development of the city's innovative model of the construction of underground integrated pipe gallery came into being.Although the underground integrated pipe gallery construction has become the most effective way to solve the problem of urban underground pipe network, the economic and social benefits are also very high, the prospect is very broad. But compared with foreign countries, the construction of China's underground comprehensive pipe gallery is still in the exploratory stage, the lack of a complete and systematic construction program. As the main force in the construction of a comprehensive pipe gallery, local government financial capital pressure is huge, other pipeline units will also invest a lot of money, and even do not want to enter the unified management of the integrated pipe gallery. Hope to share or reduce the pipe gallery construction costs and post operational management costs, funding is undoubtedly become the biggest bottleneck restricting the construction of integrated pipe gallery. So as per km of investment costs about 16 million yuan of underground comprehensive pipe gallery, the initial investment is huge, in the case of limited government financial resources, how to select a good construction business model? Simply rely on the government's power is not feasible, the government's financial capital is only the foundation construction of the underground pipe gallery, only give full play to the government's public service functions, with institutional innovation to stimulate private investment in energy, through the PPP model and discount loans, the purchase of services, the development of financial institutions to support the way, the introduction of multi-channel social capital. Not only to solve the problem of pre construction costs, but also to clear the late reasonable operating and charging mechanism.The main purpose of this paper is around the core issue of "money come from", in-depth study of how to solve the local government in the limited financial resources, investment and financing for the operation and management mode, to raise more funds from the society to the construction of underground pipe gallery. Through the analysis of the domestic and foreign academic and practical aspects of its characteristics, project design, cost sharing post operation management and other aspects of a detailed analysis, the establishment of construction cost sharing subject, post operation and profit model, the article also analyzes the Leshan and Zigong two low comprehensive pipe gallery case, hoping to start a discussion. Effect. Finally, it analyzes some problems existing in the PPP investment and financing mode of China's underground comprehensive pipe gallery, and puts forward some suggestions for the local government to provide reference for the effective use of PPP model to ensure a win-win situation. |
