The method regards capture fisheries to be the “carrier branches” producing “core inputs”, which can drive the other fisheries sectors in the Ghosh supply-driven model. These fisheries sectors are all linked with the rest of the economy and can affect it through backward linkages in the Leontief demand-driven model. The empirical findings based on the Thai fisheries corroborate findings in other literature and further reveal that capture fisheries make a much greater contribution to the economy than is usually thought.展开更多
