数字产品进口与企业产能利用率Digital Products Import and Firm Capacity Utilization
孙振亚,姚树洁
摘要(Abstract)：
提高企业产能利用率是实现经济高质量发展的现实需要。本文基于中国工业企业数据与海关匹配数据，实证考察了数字产品进口对企业产能利用率的影响与作用机制。实证结果表明，数字产品进口显著促进了企业产能利用率的提高，该结论在经过一系列稳健性检验后依然成立。机制检验结果表明，数字产品进口通过提升人力资本水平、促进企业创新以及缩短技术距离提高企业产能利用率。异质性检验发现，数字产品进口对非国有企业以及资本密集型行业提高产能利用率的促进作用更大。进一步研究发现，数字中间品进口对提高企业产能利用率的促进作用要大于数字资本品进口。随着技术距离扩大，数字资本品进口与数字中间品进口对提高企业产能利用率的促进作用呈现出先下降后上升的趋势。本文的研究结论为提高企业产能利用率，实现经济高质量发展提供重要的理论与实践意义。
