摘　　要：在贸易引力模型的基础上,引入中国基尼系数和美国基尼系数两个新变量,作为中国对美国出口的影响因素。进而构建了无基尼系数模型、乘基尼系数模型和指数基尼系数模型;并利用中国对美国1978年—2008年的出口额,依次估计了三个模型。最终,基于模型特征,选择乘基尼系数模型来解释中国对美国出口的决定因素。得出结论:中国的基尼系数增加阻碍了中国对美国的出口,美国的基尼系数增加促进了美国对中国的进口。In this paper,based on the gravity model of trade,we introduced Chinese Gini coefficient and American Gini coefficient into it.Thus,we constructed the model without Gini coefficient,the model multipled by Gini coefficient,the model eliminated by Gini coefficient and the index of Gini coefficient model.Making use of Chinese exports to the United States in 1978-2008 years,three models are tested one by one.Finally,the model multipled by Gini coefficient is chosen to explain the Chinese exports to the U.S.It is concluded that the increase of Chinese Gini coefficient hinders the Chinese exports to United states,and the increase of American Gini coefficient promotes the American imports from China.
