摘要
数字经济发展正深刻改变当下的全球贸易格局,对提升出口企业乃至整个产业国际竞争力有着重要意义。本文基于异质性企业模型并使用2004~2013年中国工业企业数据库和海关数据库匹配的样本,从理论与实证两方面研究数字经济发展对出口企业加成率以及资源配置效率的影响。研究发现:数字经济发展显著提升出口企业加成率,该结论在经过内生性问题处理和一系列稳健性检验后依然成立。机制检验表明,生产成本和生产率是数字经济发挥作用的两条重要渠道。异质性分析表明,数字经济发展提升了东部地区、资本密集型、技术密集型、非国有出口企业和低制度壁垒地区出口企业加成率。进一步分析表明,数字经济发展降低了出口企业加成率离散度,显著优化了资源配置效率。本文的研究结论对推动对外贸易高质量发展有着重要启示。
Digital economy development is profoundly changing the current global trade pattern,which is of great significance to enhance the international competitiveness of export enterprises and even the whole industry.This paper finds that digital economy development enhances exporters’markups based on the theoretical model of heterogeneous firms,and further tests the hypotheses related to the theoretical model using matched samples from Chinese industrial enterprise database and customs database from 2004 to 2013.The empirical study finds that:digital economy development significantly enhances exporters’markups,which is consistent with the theoretical model,and the finding still holds after endogeneity problem treatment and a series of robustness tests;mechanism tests show that production cost and productivity are two important channels through which the digital economy works.Heterogeneity analysis shows that digital economy development raises the markups of exporting firms in eastern,capital-intensive,technology-intensive,non-state,and low institutional barrier regions.Further analysis shows that digital economy development reduces the dispersion of exporters’markups and significantly optimizes resource allocation efficiency.The findings of this paper have important implications for promoting high-quality development of foreign trade.
