【摘要】 文章结合世界投入产出数据库（WIOD）和经济合作与发展组织（OECD）数据库，采用FH指数对2000—2021年间全球数字服务外包进行测度。研究结果表明，在此期间，全球数字服务外包呈现出明显的变迁趋势，从以“英美”为中心逐渐演变为以“中美”为中心。文章进一步分析了区域服务贸易协定对数字服务外包的影响。研究发现，缔结区域服务贸易协定能够使数字服务外包增加28.4%。机制分析表明，区域服务贸易协定通过缩小制度距离和削减数字服务贸易成本，从而提高数字服务外包水平。通过异质性分析，文章发现区域服务贸易协定能够同时推动农业、工业和服务业三个部门的数字服务外包活动。在细分服务贸易条款方面，文章发现最惠国待遇、自然人流动和保护机制三项条款对数字服务外包的增长具有显著的驱动作用。除此之外，文章还使用多种稳健性检验来提高研究结果的可靠性。文章为深入理解区域服务贸易协定如何影响数字服务外包提供了理论依据，揭示了服务贸易在推动数字服务外包发展中的重要作用。同时，该研究成果也为我国发展数字服务外包提供了有益的建议，为我国在全球数字服务外包竞争中取得优势提供了理论支持。更多还原

【Abstract】 This article combines the World Input Output Database(WIOD) and the Organization for Economic Cooperation and Development(OECD) database to measure global digital service outsourcing from 2000 to 2021 using the FH index. The research results indicate that during this period, global digital service outsourcing has shown a clear trend of change, gradually evolving from being centered around "Britain and the United States" to being centered around "China and the United States". This article further analyzes the impact of regional service trade agreements on digital service outsourcing. Research has found that concluding regional service trade agreements can increase digital service outsourcing by 28.4%. Mechanism analysis shows that regional service trade agreements improve the level of digital service outsourcing by narrowing institutional distance and reducing the cost of digital service trade. Through heterogeneity analysis, this article finds that regional service trade agreements can simultaneously promote digital service outsourcing activities in three sectors: agriculture, industry, and services. In terms of subdividing service trade terms, this article finds that three clauses, most favored nation treatment, natural person mobility, and protection mechanisms, have a significant driving effect on the growth of digital service outsourcing. In addition, this article also conducted various robustness tests to ensure the reliability of the empirical results. This article provides a theoretical basis for a deeper understanding of how regional service trade agreements affect digital service outsourcing, and reveals the important role of service trade in promoting the development of digital service outsourcing. At the same time, the research results of this article also provide useful suggestions for the development of digital service outsourcing in China, and provide theoretical support for China to gain advantages in global digital service outsourcing competition.更多还原
