| China’s government investment management model is diverse,including project legal person model,engineering command type model,infrastructure group model,professional organization model,city investment company model,etc.,which have more mature applications in the country.The Shenzhen area is dominated by the government’s centralized agency system,and has formed a typical Shenzhen model.It has greatly saved the financial resources while improving the efficiency and efficiency of government investment.As the governments at all levels in Shenzhen increased their investment in infrastructure and people’s livelihood,they began to pilot market-based agency systems to meet the rapidly increasing government investment project management needs.First,the management model of government investment construction projects was studied.This paper introduces the concept of agent construction system such as centralized government construction and market-based agent construction system,analyzes the management model of agency construction and its characteristics,and studies the theory of agent construction and investment management.Secondly,it discusses the pilot project of market-based agency construction in Shenzhen,and divides the responsibility,guarantee and rewards and punishments under the model of qualification,fee collection,agent selection,agent construction,individual commission and joint commission.Other mechanisms have been explored.Thirdly,it analyzes the investment management of the agent construction project of Longhua District General Hospital.This paper introduces the basic situation of the construction of the Longhua District General Hospital project and analyzes the investment management practices of market-based agency construction.Through analysis,it is found that there are some investment management risks in the implementation stage such as design stage,bidding stage and construction stage.Through the analysis of the investment composition,this paper analyzes the influencing factors affecting investment,and finds that there are problems such as the change of usage requirements,the control of the cost is not strict,and the design errors and omissions are encountered in the design stage.The tendering risk exists in the bidding stage,and the bidding schedule is unreasonable.Problems such as unreasonable setting of contract terms;there are capital supervision,engineering changes,delays in construction period,etc.,which affect investment management risks.Subsequently,through the ISM method,policy factors,natural factors,economic factors,and changes in usage requirements are the fundamental factors affecting project investment.Design factors,bidding and contract factors,capital supply and security factors are indirect factors affecting project investment.Materials and equipment Quantity and price factors,engineering change factors,and construction delay factors are the direct reasons for project investment.Finally,the investment management countermeasures of the implementation stage of the Longhua District General Hospital’s construction project were analyzed.In order to effectively improve the investment management level of the principal(owner)in the project implementation stage,pre-control measures should be taken from the design stage,the bidding stage and the construction stage in combination with key influencing factors.In the design stage,it is necessary to clarify the use of demand and strictly control the change of demand,implement quota design,and strictly control the quality of design through multi-party audit.In the bidding stage,the bidding supervision is strengthened through the measures of pre-approval and follow-up filing,and at the same time it is reasonable.Set contract terms;in the construction phase,measures such as centralized supervision account payment,full project guarantee and insurance shall be adopted to ensure the safety of funds,strengthen change management and control of construction period.By adopting these measures,we will effectively control investment and improve the efficiency and efficiency of government investment.Based on the principle of “simulating and perfecting while experimenting”,Shenzhen has been brave in innovation under the condition that the centralized government construction system is quite mature,and it is developing markets for some government-invested public welfare projects with large volume,complicated technology and tight time.The pilot project of the construction of the government has gradually formed a binary agency construction system with the government centralized construction system as the leading factor and the market-based agent construction system as an important supplement,which will effectively meet the increasing needs of government investment project management.Through the pilot of market-based agency system,it is conducive to promoting the reform of the supply side of high-quality public resources and continuously satisfying the people’s demand for a better life.It is believed that the reform of service-oriented government has been further advanced,and the “ distribution of services ” has become more and more powerful.More and more government investment projects will be market-based.More experts and scholars study the market-based agentconstruction system,and the whole process investment management theory of market-based agent construction system will become more mature.The investment management level of the principal(owner)will be further improved,and the investment will be more fully and effectively controlled.Therefore,the market-based agent construction system will have broader development prospects in China’s infrastructure construction,public project construction,and residential projects. |
