摘要	当前，全球正面临百年未有之大变局，政治和技术等各种因素都在推动全球价值链向着复杂多元的方向进行重构。对于中国来说，新一轮技术革命为我们带来了历史机遇，打破我国服务业所面临的“低端锁定”和“双重挤压”困境。随着互联网、大数据、5G 等数字化技术的快速发展，数字经济正在重塑全球经济格局，数字经济以高智能化以及强渗透性与服务业深度融合，从而提高了服务业的生产效率和贸易水平，加速了服务业产业的转型升级。我国的“十四五”规划提出要推进服务业的融合发展，推动服务业向专业化和价值链高端延伸。尽管近年来我国的服务业发展迅速，但大多数传统服务业仍面临着“低端锁定”的困局。因此，我们需要加快数字经济的发展，为服务业的高质量发展注入动力，从而有效促进服务业全球价值链地位的提升。本文首先对数字经济以及服务业全球价值链的相关文献以及理论基础进行梳理。结合全球价值链升级理论和技术创新理论，探讨了数字经济对服务业全球价值链地位影响的路径，并得出数字经济的发展对我国服务业全球价值链地位具有直接和间接影响，技术创新与结构升级从中扮演着中介角色。基于此，本文提出了三个假设。接着通过测算我国各省份数字经济发展水平和服务业全球价值链地位指数，并就这两个领域在各省的发展现状进行分析。尽管面临一些不利因素的冲击，我国的数字经济水平和服务业全球价值链地位仍然均呈现上升趋势，然而，东中西部地区的发展差异仍然存在。在实证研究方面，本文采取了以下三个步骤来验证数字经济对我国服务业全球价值链地位的影响：第一，通过选取数字经济发展水平、服务全球价值链地位指数作为核心解释变量、被解释变量，选取控制变量、中介变量相关指标。第二，构建了最小二乘法模型进行基准回归，并通过替换变量和删除样本法进行稳健性检验，再次证明基准回归结果有效。第三，进行异质性分析和中介效应检验。通过检验，验证了数字经济对服务业全球价值链地位影响的地区差异性，以及数字经济通过促进技术创新水平和产业结构升级两个中介提高我国服务业全球价值链地位。最后得出结论：数字经济能促进我国服务业全球价值链地位的攀升，并且产业结构升级和技术创新能发挥中介作用。根据研究结论提出政策建议：提高整体数字化水平、促进产业结构升级、加快攻关核心技术、加大人才队伍建设。
英文摘要	Currently, the world is facing unprecedented changes, and various factors such as politics and technology are driving the reconstruction of the global value chain towards a complex and diverse direction. For China, the new round of technological revolution has brought us historical opportunities, breaking the "low-end lock-in" and "double compression" difficulties faced by our service industry. With the rapid development of digital technologies such as the Internet, big data, 5G, etc., the digital economy is reshaping the global economic pattern. The digital economy is deeply integrated with the service industry with high intelligence and strong penetration, thus improving the production efficiency and trade level of the service industry, and accelerating the transformation and upgrading of the service industry. The 14th Five Year Plan of our country proposes to promote the integrated development of the service industry, and to extend the service industry towards specialization and high-end value chains. Despite the rapid development of China's service industry in recent years, most raditional service industries still face the dilemma of "low-end lock-in". Therefore, we need to accelerate the development of the digital economy and provide a strong "booster" for the improvement of the global value chain position of the service industry. Therefore, this article focuses on studying the impact of the development of the digital economy on the rise of China's service industry's global value chain position. This article first reviews the relevant literature and theoretical foundationsof the digital economy and the global value chain of the service industry.Combining the theories of global value chain upgrading and technologicalinnovation, this paper explores the path of the impact of the digital economy on the global value chain position of the service industry, and concludes that the development of the digital economy has both direct and indirect impacts on the global value chain position of China's service industry, from which technological innovation and structural upgrading play an intermediary role. Based on this, this article proposes three hypotheses. Next, an analysis of the current situation will be conducted by measuring the development level of digital economy in various provinces of China and the global value chain status index of the service industry. Overall, the level of China's digital economy and the global value chain position of the service industry are showing an upward trend. However, there are still differences in development between the eastern, central, and western regions. In terms of empirical research, this article takes the following three steps to verify the impact of the digital economy on the global value chain status of China's service industry: firstly, by selecting the level of digital economy development and the service global value chain status index as coreexplanatory variables and the dependent variable, and selecting control variables and intermediary variable related indicators. Secondly, a least squares model was constructed for benchmark regression, and robustness tests were conducted, through variable replacement and sample deletion methods, once again proving the effectiveness of the benchmark regression results. Thirdly, conductheterogeneity analysis and mediation effect testing. Through testing, the regional differences in the impact of the digital economy on the global valuechain position of the service industry have been verified, and the digitaleconomy has improved the global value chain position of China's serviceindustry through two intermediaries: promoting technological innovation level and upgrading industrial structure. Finally, The conclusion is that digital economy can promote the global value chain status of our service industry to climb, and industrial structure upgrading and technological innovation can play an intermediary role. And some policy recommendations are proposed: improving the overall level of digitalization, promoting industrial structure upgrading, accelerating the development of core technologies, and increasing the construction of talent teams.
