摘要
This paper analyzes the corn production cost in China, the U.S. and Brazil from 1997 to 2014. According to the results,（1） corn production cost in China is the highest among these three countries;（2） the rapid growth of labor cost and land cost is the major factor that promotes the increase of total corn production cost in China;（3） the level of agricultural mechanization in China has been gradually improving, and the gap between agricultural mechanization levels in China and other two countries is constantly narrowing;（4） differing from the U.S. and Brazil,China exhibits a ＂high input, low output＂ agricultural production mode. Based on the above analyses, corresponding suggestions have been presented to reduce corn production cost in China.
分析了中国、美国和巴西1997-2014年的玉米生产成本,研究表明(1)中国玉米生产成本明显高于美国和巴西;(2)人工成本和土地成本上涨是中国玉米生产成本高涨的主要原因;(3)中国农业机械化水平逐步提高,与美国和巴西的差距正在缩小;(4)不同于美国和巴西,中国目前属于"高投入低产出"的农业生产模式。根据研究结果,笔者提出了相应的降低玉米生产成本的政策建议。
