Study of inland ship water pollution control policy strategy based on Game theory

Abstract

Sanitary sewage, oily wastewater, toxicant containing wastewater, and domestic solid wastes are major pollutants from ships threating inland water bodies. These pollutants are in significant volumes and wide ranges. Therefore, great efforts have been invested in inland ship water pollution control policy and regulations. A local ship pollution control decision evolution Game model based on bounded rationality is established to obtain the key factors affecting decision-making by ships in water pollution control include cost for pollution control, subsidies and credits, administrative supervision and punishment, while key factors affecting decision-making by authorities include cost for administrative supervision and pressures from supervisors caused by not taking supervisions, thus providing recommendations on policy and measures for inland ship pollution. This study provides references for establishment of inland ship pollution control system.
