A Multi-dimensional Approach Study On The Improvement Of General Contracting Project Management Performance Under The Guidance Of Contractor’s Best Performance

With the rapid economic development,China’s construction industry has undergone tremendous changes,and at the same time,engineering projects are becoming increasingly complex and mega.The traditional construction management mode is impacted by the project general contract mode because of it’s disadvantages such as the complexity of management and the complexity of the project general contract relationship.However,most of the general contracting project management has encountered the "performance dilemma",the project management performance improvement problem urgently needs to be solved.As one of the typical international project transaction modes,the traditional DBB model has made some achievements in improving its project management performance.At the same time,risk sharing is regarded as an important starting point for performance improvement.Therefore,this paper explores the performance improvement measures under the general contracting model from the comparative analysis between the general contracting model and the traditional DBB model and the mechanism of the effect of risk sharing mediated by the best performance on the project performance.Specific research contents are as follows:Firstly,the traditional DBB model and the general contracting model are compared and analyzed.First,the advantages and disadvantages of the two models are analyzed.Secondly,the overall contract system,the scope of responsibilities and rights of project management subjects,and the risk sharing of the four types of contract demonstration texts,such as 2017 Silver Book,Yellow Book,China Construction Project Construction Contract Model(GF-2017-0201)and Project General Contracting Model Contract Model(GF-2020-0216),are analyzed.Finally,the differences between the two modes are discussed based on the above analysis results,which provides a breakthrough for the research on improvement measures of general contracting project management performance.Secondly,based on the existing research results,the theoretical model of "risk sharing-best performance-project management performance" is proposed,and the research hypothesis is put forward.A total of 204 valid data were collected by questionnaire survey,and the structural equation analysis was carried out by using MPLUS8.3 software.The results show that the three dimensions of risk sharing,execution,completeness and motivation,all have a positive impact on the best performance of the contract and project management performance.Among them,the overall path effect of incentive on project performance is the most obvious,that is,the fair and reasonable distribution of rights and responsibilities has a positive effect on the improvement of project performance;In addition,the best implementation of the treaty has a significant intermediary role.Thirdly,combined with the results of comparative analysis and empirical analysis,and based on the situation of a large number of transfer of control rights in the general contracting mode of the project,measures to improve the project management performance such as introducing technical specifications and simulating bidding by bill of quantities are proposed.Based on the current situation of insufficient amount of social capital in our country,this paper puts forward some measures to improve the project management performance after the initial design of unified bidding intervention.Based on reasonable risk sharing,the project management performance improvement measures that the owners can transfer risk and control right synchronously are proposed.In the theoretical level,this study on reasonable risk sharing as the breakthrough point of the project management,introduced as good performance as a mediation to explore risk sharing effect on the performance of project management,construction project engineering general contracting mode of risk sharing the inner mechanism of the impact on the project management performance,enrich the study of improving project management performance.On the practical level,this study provides new solutions and approaches for improving the performance of general contracting project management,and has reference and guiding significance for carrying out practical work.
