An Optimal Investment Policy to Control the Land-based Water Pollutant into the Sea of Japan (assigned to theme
Northeast Asia countries (e.g. around the Sea of Japan area) cooperate in economic and environmental policies, etc., because the comprehensive problems like the climate change and global warming occur in recent years. The ring Sea of Japan area consists of Japan, Republic of Korea, China, and Far East Russia in Northeast Asia, and the countries have to join forces in order to control the ocean environment and attain the sustainable development in the region. In this study, we try to evaluate the policy measure to control the land-based water pollutant into the Sea of Japan through a system simulation approach. The system simulation model is formulated a definition of an objective function and the structure of water pollutants inflow and the socio-economic system of the target countries and regions of the ring Sea of Japan. We present an optimal international policy for environmental investment taking account of economic situations and environmental influences of this area over a certain period of time through the dynamic simulation.
