As an important way of financing, public-private partnerships (PPPs) have been widely used in many countries. With the application of PPPs in the marine industry, the public sector should not only ensure economic benefits but also consider the environmental cost of projects when making investment decisions. From the perspective of the public sector, this study calculates the environmental cost applicable to the marine industry, selects eight economic indicators, and determines the weight based on the triangular fuzzy number–based analytical hierarchical process and rough set method respectively, and establishes a complete economic evaluation system. Finally, an example is given to prove the rationality of the system.
