Abstract: Based on Bas and Strauss-Kahn (2014) model,this paper theoretically analyzes the mechanism of the impact of input trade liberalization on capacity utilization,and conducts an empirical test with the data of Chinese enterprises from 2000 to 2013.It is found that the input trade liberalization can improve the capacity utilization of enterprises.Comparison of different types of enterprises finds that the trade liberalization of inputs has a greater positive effect on the capacity utilization of local enterprises and firms which depend more on export of intermediate goods.Further study by building an intermediary effect model and using the double difference method reveals that the input trade liberalization has a sustainable impact on the capacity utilization rate,and the effect of obtaining high-quality and diversified intermediate goods and technology spillover are the important paths for the input trade liberalization to affect the utilization rate of production capacity.

摘要： 本文借鉴Bas和Strauss-Kahn(2014)的模型,分析中间品贸易自由化对企业产能利用率的作用机制,并采用2000~2013年中国制造业企业数据进行实证检验。结果显示,中间品贸易自由化有助于提升企业产能利用率,且对本土企业和高中间品进口依存度行业企业的产能利用率的正向效应更大。构建中介效应模型和进一步采用双重差分法,发现中间品贸易自由化通过优质多样化中间品的获得效应和生产率改进效应两个渠道对企业产能利用率产生持续性影响。
