With the rapid development of coastal economy and marine development activities, marine environmental protection issues have become increasingly prominent, leading to the development of marine environmental protection enterprises which have gradually become a hot spot of concern. However, as China's marine environmental protection enterprises are mostly still at the stage of start-up and growth, it is urgent to maximize the value creation of marine environmental protection enterprises and optimize the value through the market value management. This paper selects 46 listed environmental protection companies as research samples, studies the management performance of them through factor analysis and multiple regression, and tests the relationship between various influencing factors and market value management performance. The study found that such factors as operational capacity, innovation capability, stockholder's rights drive, investor structure professionalism, and the number of disclosed mergers and acquisitions have a significant positive impact on market value management performance of marine environmental protection enterprises, while factors like capital structure, the number of litigations and arbitrations have a significant negative impact on market value management performance, and there is an inverted U-shaped relationship between ownership concentration and market value management performance. This research has certain enlightenment significance for marine environmental protection enterprises to improve the performance of market value management.
