Currently, in many parts of China, several normative documents related to marine ecological protection and marine environmental governance have been issued. However, the behavior of production enterprises discharging waste pollutants into the sea illegally and excessively continues unabated, with poor effectiveness in utilizing big data technology for monitoring and adjudication. In order to break the regulatory dilemma of insufficient awareness of marine environmental data application, low enforcement efficiency, and imbalance of public and private rights in the judicial field under big data, it is necessary to clarify the underlying reasons such as narrow regulatory perspective, single subject, biased objectives, and information imbalance. Subsequently, under the premise of transforming the perspective of environmental legal regulation, it is essential to reconstruct regulatory means that align with big data thinking, allocate diverse regulatory subjects, and follow up with the development of corresponding market support paths. The ultimate goal is to achieve the sustainable utilization of comprehensive legislation in the construction of marine ecological civilization.
