摘要
本文选取大豆、梗稻、玉米三种农作物,使用1994—2006年间若干代表年份的数据,通过DEA方法计算了我国农业国际化进程中农作物的种植效率,并在此基础上研究农作物种植效率与国际化开放程度之间的关系。研究结果表明,在我国加入WTO之后,三种农作物的技术效率整体上呈现震荡上升的趋势;实证检验发现,农作物开放程度的提升确实会带来种植效率的显著提升,尤其是对于具有出口优势的玉米,开放程度对种植效率的影响更为显著。
By using the representative annual data from 1994 to 2006 with soybean, japonica rice and corn as the three types of farm crops, this paper applied DEA method to analyze the planting efficiency of farm crops during the period of Chinese agricultural internationalization and their relationship. Empirical results showed that technical efficiency of three crops presented upward trends after China joined the WTO, and it was an important stage in the internationalization of agriculture for our country during this time. This paper also found that the degree of openness would significantly improve the planting efficiency, especially for corn, which had an export advantage.
