潜力在农业生产，食物价格和农民上简历乙醇扩大影响的现在的纸分析是在中国的不同区域的收入。结果显示出受欢迎的那增加因为生产简历乙醇的化工物品将在农业产品的价格导致大增加。increase in prices 将以更低的米饭和小麦生产的成本在化工物品的生产触发重要上升。学习也表明农民的收入上的简历乙醇的影响主要在区域和农民组之中变化。以后给简历乙醇生产的期望的扩大，并且为在中国的化工物品生产的有限陆地资源，为简历乙醇的化工物品在中国的简历乙醇节目的大规模扩大前要求小心的分析的不同庄稼的生存能力。在中国的简历乙醇生产应该更正在依靠简历乙醇技术的第二代(即使用纤维素生产简历乙醇) ，并且中国的政府应该在这个领域里增加研究投资。

英文摘要：

The present paper analyzes the potential impacts of bio-ethanol expansion on agricultural production, food prices and farmers＇ incomes in different regions of China. The results show that increase in demand for feedstock to produce bio-ethanol will lead to large increase in the prices of agricultural products. The increase in prices will trigger a significant rise in the production of feedstock at the cost of lower rice and wheat production. The study also reveals that the impacts of bio-ethanol on farmers＂ incomes vary largely among regions and farmer groups. Given the expected expansion of bio-ethanol production in the future, and the limited land resources for feedstock production in China, the viability of different crops as feedstock for bio-ethanol requires careful analysis before a large-scale expansion of China＇s bio-ethanol program. Bio-ethanol production in China should be relying more on the second generation of bio-ethanol technologies （i.e. using celluloses to produce bio-ethanol）, and China＇s government should increase research investment in this field.
