With the intensification of marine development activities, the comprehensive benefit assessment of marine development type is of great significance to promote the coordinated development of marine resources, environment and economy. In this study, four typical types of marine development, including aquaculture, offshore wind power, sewage dumping and port industry in Jiangsu Province, are taken as examples. Based on the calculation of economic net benefit, loss value of wetland ecosystem service function value, loss value of fishery resources and ecological profit and loss value, the comprehensive benefit evaluation value per unit area is obtained. It is found that the order of comprehensive benefit value from high to low is port industry, offshore wind power, sewage dumping and aquaculture, in which the contribution of economic net benefit is the largest. After deducting the net social and economic benefits, the comprehensive benefit values are sorted as offshore wind power, sewage dumping, aquaculture and port industry. The objective evaluation of the comprehensive benefit value of the type of marine development and the in-depth analysis of its internal composition can help us to understand the main influencing factors of the type of marine development, which is of positive significance to promote the reasonable selection of the type of marine development in each region and adjust the marine development countermeasures in time.
