农产品国际市场的两个特征是出口国和进口国的双边市场力量以及非转基因（non-GM）和转基因（GM）产品的共存。在目前大多数关于国际农产品市场市场力量的研究中，都没有考虑到这两个特点。本研究建立了非转基因商品与转基因商品相互作用的双边寡头垄断模型，并对美日大豆贸易进行了实证估计。估算结果显示，美国出口商和日本进口商几乎平分市场主导权。本研究的分析提供了新的市场力测度方法，提高了对世界大豆市场的认识。
Abstract Two features of international markets of agricultural commodities are bilateral market power of exporting and importing countries and the coexistence of non-genetically modified (non-GM) and genetically modified (GM) products. The two features were not taken into account in most extant studies on market power in international agricultural commodity markets. This research develops a bilateral oligopoly model with the interaction between non-GM and GM commodity and conducts an empirical estimation for U.S.–Japan soybean trade. The estimation results show that U.S. exporters and Japanese importers are almost equally sharing the dominance of market power. The analysis in this research provides new measures of market power and improves the understanding on world soybean markets.
