摘要: 本文利用1989-2008共20年中国出口到美国农产品高度细分的贸易数据,通过引入生存分析来研究中国对美国农产品出口持续时间。研究发现这一贸易关系的持续时间很短,HS10分位农产品的平均生存时间为3.9年,中位生存时间为2年,生存时间众数为1。稳健性检验表明产品分类的不同层次对结果的影响不显著。在此基础上提出政策建议和研究的不足。

Abstract: This paper uses highly disaggregated trade data of China Agriculture Products exporting to the U.S. from 1989 to 2008. We employ survival analysis to study the duration of China Agriculture Products exporting to the U.S. Our findings indicate the duration of this trade is very short. The mean duration of HS10-digit Agriculture Products exporting to the U.S. is 3.9 years, the median is 2 years and the mode is 1. Robust test indicates that the result is no difference across product classification levels. On this basis, we propose policy recommendations and the lack of research.
