文章以中国加入WTO为背景,在一个自然实验的框架下研究了中间品贸易自由化的生产率效应。利用2000—2007年中国工业企业数据和海关贸易数据的合并样本进行倍差法估计后发现,中间品贸易自由化显著提高了企业生产率,并且这一结论在改变核心指标的测度方法、使用不同的模型设定和采用不同计量方法的情况下也较为稳健。进一步的影响机制分析表明,进口种类的拓展与进口质量的提升是中间品贸易自由化促进企业生产率提升的两个渠道,其中＂进口质量＂渠道更为重要。最后,文章还实证考察了中间品贸易自由化、资源再配置与行业生产率增长之间的关系,发现资源再配置效应是中间品贸易自由化促进行业生产率增长的重要途径。

Under the background of China＇s entry into WTO,this paper studies the productivity effect of trade liberalization of intermediate inputs in a framework of natural experiment.Based on the merged sample of industry firms and customs trade from 2000 to 2007 and difference-in-difference estimation,it indicates that trade liberalization of intermediate inputs significantly improves firm productivity,which is robust in the conditions of changes in measurement of core indicators,different model setting and econometric methods.Further test of effect mechanisms shows that the expansion of import types and the improvement of the quality of imports are two ways to the promotion role of trade liberalization of intermediate inputs in firm productivity and the channel concerning the quality of imports is more important.Finally,it empirically tests the relationship between trade liberalization of intermediate inputs,resources reallocation and the growth of industry productivity,and shows that the resources reallocation effect is the key route to the promotion role of trade liberalization of intermediate inputs in industry productivity.
