Feasibility Study of a Free Trade Agreement between Japan and ASEAN, and Quantitative Analysis of Economic Impacts on Agricultural Sector

包括阿森、日本、韩国和中国在内的东亚国家的农业具有几个共同的特点，如小规模水稻种植，这些国家必须共同制定一项国际粮食贸易规则，使其未来的农业可持续发展，以应对拥有大型农场的出口国的严重自由贸易压力。建立东亚自由贸易区是加强这些国家之间合作关系的一种方式。然而，这些国家之间的农业生产率仍然存在巨大差异。因此，我们应该寻求一种共同的农业政策的可能性，通过创建一个与各国GDP水平成比例的共同基金来调整各国之间的自由贸易协定收益不平衡，就像欧盟预算一样。我们提出了一个系统的模型来检验这些计划的可行性，综合考虑了大米供应的自给率、预算约束、大米关税降低限额和氮素平衡。

Agriculture in East Asian countries, including ASEN, Japan, Korea, and China, has several common characteristics such as small-scale rice farming, and it is important for these countries to jointly establish an international food trade rule which enables their agricultural sustainability in the future against the severe free trade pressure from exporting countries with large-scale farms. Forming an East Asian Free Trade Area is a way to strengthen cooperative relationships among these countries. However, there are still huge differences in agricultural productivity among these countries. Therefore, we should seek possibilities of a common agricultural policy that adjusts imbalance of FTA gains among the countries by creating a common fund collected in proportion to the GDP level of each country just like the EU budget. We proposed a systematic model to examine the feasibility of such programs considering combination of self-sufficiency rate of rice supply, budgetary constraints, reduction limit of rice tariffs, and nitrogen balance.
