信息技术迅猛发展，数字经济成为全球经济增长的关键动力。服务业作为国际贸易的重要支柱，其出口对提升国家竞争力和经济结构优化至关重要。中国作为发展中大国，数字经济的繁荣对服务贸易产生深刻影响，推动生产效率提升、服务模式创新和范围扩大，为服务出口带来新机遇。对此，本文展开中国数字经济发展水平对服务出口的影响研究。本文以我国27个省级行政区域2006-2021年共16年的面板数据为样本，参考赵涛（2020）的做法，构建中国数字经济发展指标体系，被解释变量为各省的服务贸易出口额，且添加了控制变量。在模型通过相关性检验、F检验和霍斯曼检验后，进行基准回归，并且加以稳健性检验以确保回归的稳健性，以及异质性分析以分区域研究不同区域数字经济对服务出口贸易的影响。本文结论为：一是数字经济发展每提高1%，服务出口贸易额将增加0.51%。二是数字经济通过提高出口效率、优化出口质量及促进产业融合等途径，积极推动了服务出口的发展。三是数字经济发展对服务贸易出口的影响在不同地区间存在显著差异，东部省份表现最为显著，西部省份也获得了跨越式发展机遇。这些结果揭示了数字经济与服务出口之间的复杂关系，为政策制定者提供了推动两者协调发展的科学依据。

With the rapid development of information technology, the digital economy has become a key driver of global economic growth. As an important pillar of international trade, the export of services is crucial for enhancing national competitiveness and optimizing economic structures. As a major developing country, China's booming digital economy has had a profound impact on service trade, driving improvements in production efficiency, innovation in service models, and expansion in scope, bringing new opportunities for service exports. In this regard, this paper studies the impact of China's digital economy development level on service exports. Using panel data from 27 provincial administrative regions in China from 2006 to 2021 as a sample, and referencing the approach of Zhao Tao (2020), this paper constructs an indicator system for China's digital economy development. The explained variable is the export value of service trade in each province, and control variables are also included. After passing the correlation test, F-test, and Hausman test, baseline regression is conducted, and robustness tests are performed to ensure the robustness of the regression, as well as heterogeneity analysis to investigate the impact of digital economy on service export trade in different regions.The main findings of this paper are as follows: First, a 1% increase in the development of the digital economy will lead to a 0.51% increase in service export trade. Second, the digital economy actively promotes the development of service exports by improving export efficiency, optimizing export quality, and promoting industrial integration. Third, there are significant differences in the impact of digital economy development on service trade exports across regions, with the most significant performance in eastern provinces, and western provinces also obtaining leapfrog development opportunities. These results reveal the complex relationship between the digital economy and service exports, providing scientific evidence for policymakers to promote the coordinated development of both.
