摘要 我国进出口贸易经历了1994年汇率体制并轨至2001年加入WTO等重大事件,发生结构变化的可能性较大.本文构造断点内生的检验模型并通过仿真产生检验统计量的临界值,检验1981至2006年中国进出口贸易额月度数据序列结构变化、讨论国际贸易环境和贸易政策变化对我国进出口贸易额的影响.结果表明,改革开放以来我国进口序列并没有发现结构断点;出口额序列是分断趋势平稳的,比较集中的结构变化断点发生在2001年中期,其它断点分别发生在1994年2月、96年7月和97年11月;它们与相关的重大事件对应.结果说明我国出口贸易是由国际贸易环境决定的内生增长过程;而贸易政策对进口贸易有持续性影响,即进口贸易是外生增长过程. Foreign trade of China has experienced a series of important events such as unification of exchange rates in 1994 to the entrance to the WTO,which probably induced structural changes for the import and export trade of China.By constructing test models in endogenous break points and producing critical values for test statistics on Mont Carlo simulation,in this paper,the structural changes in monthly data of Chinese export and import are tested to investigate effects of the change of international trade envir...
