The Institute has established Marine Economics as a secondary discipline under the primary discipline of Applied Economics. Marine Economics is a branch of economics that studies the optimal allocation of marine resources and the laws governing marine economic activities and development. It encompasses both micro-level and macro-level perspectives. Specifically, Marine Economics is an interdisciplinary applied discipline grounded in economic theory and integrating methodologies from mathematics, statistics, management science, and marine science. Its core approach involves constructing quantitative models to analyze a series of complex problems characterized by stochastic relationships in the marine economy. The discipline aims to uncover the dynamics of marine economic productivity, the evolution of production relations, and the underlying laws of marine economic development, thereby providing scientific foundations and optimized solutions for planning, organizing, managing, decision-making, and controlling marine economic activities.

Marine Economics is inherently interdisciplinary. While rooted in economic science, it draws extensively on marine science, atmospheric science, environmental science, systems science, information science, control science, as well as management science, mathematics, statistics, physics, computer science, law, and other fields.

Main Research Areas and Directions of the Marine Economics Discipline:

1. Evaluation of Marine Economic Policies and Quantitative Analysis of Investment and Financing. This area includes three specific research components:
(1) Big data analytics and modeling in marine economics;
(2) Analysis and evaluation of marine economic policies;
(3) Quantitative analysis of investment and financing in the marine economy.

2. Sustainable Development of the Marine Economy and Resource & Environmental Protection. This area includes three specific research components:
(1) High-quality development of the marine economy;
(2) Sustainable utilization of marine ecosystems, resources, and environmental protection;
(3) Integrated land-sea planning and marine industrial development strategies.

3. Marine Economic Monitoring, Early Warning Systems, and Global Ocean Governance. This area includes three specific research components:
(1) Marine disasters and risk management;
(2) Monitoring and early warning systems for marine economic security;
(3) Climate change and global ocean governance.
