中美玉米种植成本与收益比较研究

A Comparative Study of Corn Cost and Benefit Between China and the United States

通过对中美玉米种植成本与收益的比较分析,发现美国的玉米种植成本一直高于中国,而收益低于中国,但从2010年开始,中国玉米种植成本高于美国,造成中国玉米种植成本增加的主要原因是土地成本的快速增加,另一方面,美国玉米种植的收益呈现上升趋势,因而,中国玉米种植的比较优势逐渐丧失。得出的对策包括增加非农就业机会,加大农业补贴力度及加快土地流转和规模经营。

The cost of corn of the United States has been higher than that of China, and the income lower than China through the comparative analysis on corn cost and benefit between China and the United States. But China＇s corn planting began to cost more than that of the United States from 2010, and land cost was the main impetus of rapid increase of Chi na＇s corn planting cost. On the other hand, corn yield in the United States had an increasing tendency. As a result,the comparative advantages of China＇s corn planting were losing gradually. The implied policies included increasing employment opportunities, enhancing agricultural subsidy and speeding up the circulation of land and planting in large scale.
