The development of the digital economy significantly relies on promoting economic liberalization and achieving high-end embedding of manufacturing into the global value chain (GVC). Based on the heterogeneous firm model, this paper introduces the factors of digital economy development, aggregates the production behavior of firms at the national level, and empirically examines the effects of digital economy development on the centralization of the GVC network and the internal mechanisms. The results show that the development of the digital economy significantly enhances a country's centralization of GVC network, primarily through enhancing productivity and alleviating resource misallocation. Meanwhile, digital economy development contributes more to the centralization of the GVC network in developed countries and high institutional quality industries. Further analysis shows that digital economy development not only enhances a country's centralization of GVC network but also extends the length of a country's GVC and promotes a country to climb up the GVC.
数字经济的发展在很大程度上依赖于推动经济自由化以及实现制造业在全球价值链（GVC）中的高端嵌入。基于异质性企业模型，本文引入数字经济发展因素，汇总国家层面企业的生产行为，并实证检验数字经济发展对全球价值链网络集中化及内部机制的影响。结果表明，数字经济发展显著提升了一个国家在全球价值链网络中的集中化程度，主要是通过提高生产率和缓解资源错配来实现的。与此同时，数字经济发展对发达国家和制度质量高的行业在全球价值链网络集中化方面的贡献更大。进一步分析表明，数字经济发展不仅提升了一个国家在全球价值链网络中的集中化程度，还延长了一个国家全球价值链的长度，并推动一个国家在全球价值链中攀升。
