Abstract:In recent years, the project management of government-invested projects has been gradually standardized, and the supervision system has been gradually improved, which has effectively played a role in saving financial funds, improving the performance of fund use, and building high-quality engineering projects. By establishing a scientific and standardized operation mechanism for the construction and implementation of government-invested projects, and improving the standardization of the construction and implementation process, the engineering management level of government-invested construction projects has been continuously improved and improved. For this reason, this paper analyzes the problems existing in the management of the double-main project of the current government-invested project, takes the construction of the actual project of Fangchenggang Baishawan International Medical Park as an example, discusses the specific measures aimed at improving the level of project management by the double-main project management mode, and puts forward corresponding countermeasures and suggestions, in order to better play the leading role of government investment in social and economic aspects.
