有形数字产品进口多样性与企业出口韧性

Import Diversification of Visible Digital Products and Firm Export Resilience

在数字贸易快速发展的背景下,借助数字进口贸易增强企业出口韧性是中国应对外部环境变化、防范风险的现实需要。文章基于中国工业企业数据库与中国海关匹配数据,以2008年金融危机冲击作为研究背景,实证考察了有形数字产品进口多样性对企业出口韧性的影响及作用机制。实证结果表明,有形数字产品进口多样性能够显著增强企业出口韧性,该结论经过一系列稳健性检验后依然成立。机制检验结果表明,出口产品质量提升效应、出口多样化效应以及出口结构优化效应是有形数字产品进口多样性影响企业出口韧性的中间渠道。异质性检验结果发现,有形数字产品进口多样性对企业出口韧性的促进作用在资本密集型行业、非国有企业以及高数字经济发展地区的表现更显著。文章的研究结论为中国搭乘数字贸易“顺风车”,增强企业出口韧性,早日迈入贸易强国行列具有重要的理论与实践意义。

With the rapid development of digital trade,enhancing the firm export resilience with the help of digital import trade is the realistic need for China to cope with changes in the external environment and prevent risks.Based on the matching data of the Chinese industrial firm database and China Customs,and takes the 2008 financial crisis as the research background,this paper empirically tests the impact of the import diversity of visible digital products on the firm export resilience.The empirical results show that the diversification of visible digital product imports can significantly enhance the firm export resilience.This result is significant after a series of robustness tests.The mechanism test results show that the effect of export product quality improvement,export diversification effect and export structure upgrading effect are intermediate channels for the diversification of visible digital product imports to affect the firm export resilience.The heterogeneity test results show that the effect of the diversification of visible digital products on the firm export resilience is more significant in capital-intensive industries,non-state-owned enterprises and regions with high digital economy development.The results have important theoretical and practical significance for China to enhance the firm export resilience,and enter the ranks of trading powers at an early date with the help of digital trade"free rider".
