Abstract: Based on panel data of 289 cities in China, this paper empirically tests the influence of imported products' structure on the capacity utilization rate and its influence mechanism. The results are as follows: From the perspective of the overall effect, the increase in the import share of capital goods and intermediate products has a significant promotion effect on the capacity utilization rate, and the increase in the import share of consumer goods has a significant inhibitory effect on the capacity utilization rate. From the perspective of the transmission path, the import of capital goods can improve the capacity utilization rate with the help of cost saving and technological innovation mechanism; the import of intermediate goods can promote the capacity utilization rate with the help of technological innovation mechanism; consumer goods can't promote the utilization rate of production through the above mechanism. Heterogeneity analysis finds that the promotion(inhibition)effect of increasing the import share of capital goods and intermediate goods(consumer goods)on the capacity utilization rate is more obvious in regions with higher capacity utilization rate and equipment technology content.

摘要： 本文基于中国289个城市的面板数据,实证检验进口产品结构对产能利用率的影响效应和作用机制。研究结果表明,资本品和中间品进口份额增大对产能利用率具有显著的促进作用,消费品进口份额增大对产能利用率具有明显的抑制作用;资本品进口借助成本节约和技术创新机制提升产能利用率,中间品进口借助技术创新机制提升产能利用率,消费品进口则无法凭借成本节约和技术创新机制改善其对产能利用率的抑制作用;资本品和中间品(消费品)进口份额增大对产能利用率的促进(抑制)作用在产能利用率较高地区和大城市更为明显。
