数字基础设施赋能数字服务贸易高质量发展研究——基于出口技术复杂度视角的分析

Research on Empowering High Quality Development of Digital Service Trade with Digital Infrastructure——Analysis based on the perspective of export technology complexity

随着数字经济时代的到来,数字基础设施为数字服务高质量发展打造了新的发展基石。本文基于2005-2021年跨国面板数据,从出口技术复杂度视角出发,探讨数字基础设施对数字服务高质量发展的影响作用。研究发现:(1)数字基础设施可以有效增强数字服务出口技术复杂度;(2)数字基础设施显著促进金融、电信计算机和信息、知识产权使用费服务的出口技术复杂度,而对个人文化与娱乐、保险和养老金、其他商业服务的出口技术复杂度无明显影响。与高收入水平国家相比,低收入水平国家数字基础设施的推动效果更强;(3)数字基础设施能够通过人力资本渠道,间接提升数字服务出口技术复杂度;(4)在研发强度约束下,数字基础设施对数字服务出口技术复杂度具有非线性的边际递减效应。鉴于此,应加快数字基础设施发展,优化制度环境保障;关注数字服务贸易重点领域,努力缩小数字鸿沟;搭建国际数字化交流平台,培育数字化专业人才;注重提升研发投入效率,深化数字基础设施建设质量导向。

With the advent of the digital economy,digital infrastructure creates a new development cornerstone for the high-quality development of digital services.Based on cross-country panel data from 2005-2021,this paper explores the impact of digital infrastructure on the high-quality development of digital services from the perspective of export technological complexity.The study finds that:,(1)Digital infrastructure can effectively enhance the export technical complexity of digital services;(2)Digital infrastructure significantly contributes to the export technical complexity of financial,telecommunication computer and information,and intellectual property royalty services,while it has no significant impact on the export technical complexity of personal culture and entertainment,insurance and pension,and other business services.The promotion effect of digital infrastructure is stronger in low-income level countries compared to high-income level countries;,(3)Digital infrastructure can indirectly,enhance the export technological complexity of digital services through the human capital channel;(4)Under the constraint of R&D intensity,digital infrastructure has a non-linear diminishing marginal effect on the export technological complexity of digital services.In view of this,the development of digital infrastructure should be accelerated and the institutional environment should be optimised for protection;attention should be paid to the key areas of digital services trade and efforts should be made to narrow the digital divide;an international digital exchange platform should be built and digital professionals should be cultivated;attention shouid be paid to enhancing the eficiency of R&D inputs,and deepening the quality-orientation of digital infrastructureconstruction.
