| With the rapid development of economy,the construction demand of urban underground infrastructure is constantly increasing.The construction ofurban underground utility tunnel can improve public services,improve living environment and reduce traffic congestion,so it is vigorously promoted by the state.The urban underground utility tunnel project has a large investment and limited financial funds.The government encourages social capital to invest in the project.The PPP model can effectively solve the problem of capital shortage.As a large number ofurban underground utility tunnelprojects are put into use,problems such as imperfect laws and regulations,lack of specialized management agencies and unclear cost sharing are exposed.At present,it is urgent to solve these problems and promote the rapid development of urban underground utility tunnel in PPP mode.This paper firstly combed the underground pipe gallery PPP model definition and operation fee of relevant theoretical knowledge,combined with the characteristics of the underground pipe gallery to determine its economic attribute and then put forward the professional operations management company is responsible for the utility tunnel operation,in the late research company operations management organization structure and main functions,from the pipe rack ancillary facilities of the main structure of pipeline maintenance operations management from three concrete expansion and then analyzes the content of the PPP model of underground pipe gallery component of the total cost and operating income,combined with the case from the cost directly Two aspects of external benefit and traditional comprehensive comparison and analysis of buried pipe,determine the government and the investment proportion of pipeline unit and pipeline unit allocation proportion between the clear operation and pricing factors affecting the main charge,on the basis of the original cost allocation method is optimized,the improved version of space proportion method is put forward,in order to boost the enthusiasm of the pipeline unit into the corridor,according to the theory of incentive mechanism to build the PPP pattern of underground comprehensive utility tunnel toll pricing game model of the project,to determine when all pipeline unit selection into the gallery to achieve economic benefit maximization,charging for same type project operation to provide certain reference basis... |
