数字服务贸易壁垒对ICT产品出口的影响——基于跨国面板数据的研究

The Impact of Digital Service Trade Barriers on ICT Exports—Research Based on Transnational Panel Data

摘要: 本文基于全球2014~2021年49个国家的面板数据，引入数字服务贸易壁垒指标，在理论分析的基础上，实证研究数字服务贸易对ICT产品出口的影响。实证发现：数字服务贸易壁垒会显著抑制ICT产品出口，并且具有国家间的异质性：发展中国家比发达国家抑制性强，非OECD国家比OECD国家的抑制作用更明显。文章还探索了数字服务贸易壁垒分政策领域对ICT产品出口的影响。基于此，本文讨论了相关的对策建议，为降低数字服务贸易壁垒与促进ICT产品出口的提供有效的思路。

Abstract: Based on the panel data of 49 countries from 2014 to 2021, this paper introduces the index of digital service trade barriers, and empirically studies the impact of digital service trade on ICT product exports on the basis of theoretical analysis. The empirical findings show that digital service trade barriers can significantly inhibit the export of ICT products, and there is heterogeneity among countries: developing countries have stronger inhibitions than developed countries, and non-OECD countries have more inhibitions than OECD countries. This paper also explores the impact of digital service trade barriers on ICT exports. Based on this, this paper discusses relevant countermeasures and suggestions to provide effective ideas for reducing trade barriers in digital services and promoting the export of ICT products.
