| 摘 要： | 针对中国大豆进口持续增加且不同主产省区大豆播种面积比例波动的大小和方向都不同的现象，建立了大豆播种面积回归模型，分析了我国各大豆主产省区大豆播种面积波动的原因。模型回归结果表明：我国各大豆主产省区的大豆与其竞争作物的净收益差异是导致不同省区大豆播种面积变化的主要原因，同时不同省区的农业产业结构、农民自身资源配置、制度改革等因素对本省区的大豆播种面积也具有不同程度的制约或促进作用。

| Abstract: | This paper establishes the regression model to analyze the reason of the fluctuation of soybean acreage in China.The result shows that the difference of net income ratio between soybean and its competitive corn is the main reason to cause this fluctuation.The policy on soybean is also one factor causing the fluctuation.Furthermore,the agricultural industrial structure,human resources of farmers and policy reformation on soybean play different roles in the soybean acreage of different provinces. |

| Keywords: | main province of soybean production relative return fluctuation of soybean acreage |
