摘要: 本文检验数字中间品进口对企业出口国内附加值率的影响及其理论机制,发现数字中间品进口显著提升企业出口国内附加值率,该结论经一系列稳健性检验后依然成立。数字中间品进口通过提升企业的生产率和成本加成率影响企业的出口国内附加值率,对一般贸易和混合贸易企业、非国有企业、东部地区企业的出口国内附加值率具有显著的提升作用。上述结论有助于进一步了解数字中间品进口的微观经济效应,不仅丰富了既有的相关研究文献,也为政府制定相应的优惠政策来提升企业出口国内附加值率提供有益的借鉴。

关键词: 数字中间品进口, 国内附加值率, 全球价值链升级

Abstract: Against the backdrop of high-quality economic development and the upward trend of manufacturing towards the high end of the value chain, this paper studies the impact of digital intermediate goods imports on the domestic value-added rate(DVAR)of enterprise exports and its theoretical mechanism, and empirically tests the theoretical mechanism. The research results indicate that the import of digital intermediate goods significantly increases the domestic value-added rate of enterprise exports, and this conclusion still holds true after a series of robustness tests. The impact mechanism indicates that the import of digital intermediate goods affects the domestic value-added rate of enterprises' exports by enhancing the “productivity effect” and “cost markup effect”. Heterogeneity tests indicate that the import of digital intermediate goods has a significant effect on improving the domestic value-added rate of exports for general trade enterprises, mixed trade enterprises, non-state-owned enterprises, and enterprises in the eastern region. This study helps to further understand the microeconomic effects of digital intermediate goods imports, not only enriching relevant literature, but also providing useful references for the government to provide corresponding preferential policies to promote the domestic value-added rate of enterprise exports.

Key words: Import of Digital Intermediate Goods, Domestic Value-added Rate, Global Value Chain Upgrading
