【摘要】：本文从进口角度重新审视国际贸易对企业生产率的影响,在合并2000-2006年中国工业企业数据库和海关贸易统计库的基础上,采用随机占优理论和倍差匹配方法,就中国企业进口行为中是否存在"自我选择"效应以及"进口中学"效应进行实证研究。研究发现:(1)中国企业进口同时存在"自我选择"效应和"进口中学"效应。(2)进口企业自身技术水平差异是决定两种效应发挥的重要因素。(3)无论是"自我选择"效应还是"进口中学"效应,在资本品进口样本中体现得更为显著。本文的检验结果及其解释,为理解进口对中国企业生产率的作用效应,判断进口对中国经济发展的综合影响,提供了更为合理的微观经验证据。
[Abstract]:This paper re-examines the impact of international trade on enterprise productivity from the perspective of import. On the basis of merging the database of Chinese industrial enterprises and customs trade statistics database from 2000 to 2006, this paper adopts stochastic dominance theory and double matching method. This paper makes an empirical study on the existence of "self-selection" effect and "import middle school" effect in the import behavior of Chinese enterprises. It is found that: (1) there are both "self-selection" effect and "import middle school" effect at the same time in the import of Chinese enterprises. (2) the difference of their own technology level is an important factor that determines the two effects. (3) there is no effect on the two effects. On the "self-selection" effect or the "imported Middle School" effect, It is more significant in the sample of imports of capital goods. The results and explanations of this paper provide more reasonable microscopic empirical evidence for understanding the effect of imports on the productivity of Chinese enterprises and judging the comprehensive effects of imports on China's economic development.
