Can government subsidies promote the construction of “Blue Basic Farmland”? Analysis of multi-subject management model in mariculture areas

Abstract

The implementation of the “Blue Basic Farmland” system for farming ocean is a crucial strategy to ensure food security. This study simulates and analyzes the impact of government fishery subsidies on promoting “Blue Basic Farmland” construction. A tripartite evolutionary game model involving the government, fishermen and fishery enterprises was used”. Subsequently, the fishery subsidy strategy of “Blue Basic Farmland” construction was simulated and analyzed. The following findings are derived. First, fishery subsidies contributed to “Blue Basic Farmland” construction by promoting the participation of fishing enterprises and supporting fishermen. Second, the amounts of fishery subsidies were not the high the better, and different amounts of fishery subsidies had varying effects. Third, subsidizing fishery enterprises was more effective in promoting the construction of “Blue Basic Farmland” compared to subsidizing fishermen. In light of these findings, we proposed the following policy recommendations. The government ought to establish subsidies specifically tailored for “Blue Basic Farmland” construction, while also judiciously controlling the subsidies amounts. Moreover, the focus of these subsidies should be directed towards supporting fishery enterprises.
