Marine enterprises urgently need an effective management system to ensure the quality of production. First, it is necessary to extract the key technologies to improve the management level of ship and coastal engineering. According to key technical achievements, a prototype system is designed and developed to help China's shipping industry and shipping enterprises carry out scientific and standardized management. From the angle of supervision enterprise, this paper used data envelopment analysis (DEA) to establish a system of engineering supervision, institution management, a performance evaluation index, and an evaluation method of analysis of the main influencing factor in performance management of project supervision institutions on the basis of comprehensive analysis of both their characteristics and construction of an index system of the DEA model.
