数字产品贸易如何影响全球价值链地位——基于ICT贸易网络结构的视角

How Does Digital Trade Network Structure Affect Global Value Chain Position——From the Perspective of ICT Trade Network Structure

本文基于社会网络方法,采用2000—2018年全球42个国家的双边信息通信技术(Informationand Communication Technology,ICT)贸易数据测算全球数字产品贸易网络结构指标,考察其对全球价值链地位的影响及作用机制。研究结果显示:一国数字产品贸易网络的深度和广度对其全球价值链地位的提升具有显著促进作用;数字产品贸易网络的深度能够显著提高非高收入国家、非OECD国家、劳动密集型产业、资本密集型产业、技术密集型产业、高技术制造业和生产性服务业的全球价值链地位,网络的广度能够显著提高高收入国家、资本密集型产业和生产性服务业的全球价值链地位;一国的数字产品贸易网络结构能够通过促进技术进步和实现价值创造提高其全球价值链地位。本文的研究结论为世界各国制定促进数字经济发展和提升全球价值链地位的政策提供经验证据。

Based on the social network method, this paper used the bilateral Information and Communication Technology(ICT) trade data of 42 countries from 2000 to 2018to measure the network structure index of global digital products trade, and investigated its influence on the global value chain(GVC) position and its mechanism. The results show that: first, the depth and breadth of a country,s digital product trade network have a significant role in promoting the GVC position. Second, the depth of the digital product trade network has a significant impact on the global value chain position of non-high-income countries, non-OECD countries, labor-intensive, capital-intensive, technology-intensive industries, high-tech manufacturing and producer services, while the breadth of the network has a significant effect on the global value chain position of high-income countries, capital-intensive industries and producer services. Third, the structure of a country,s digital goods trade network can influence its GVC position by facilitating technological progress and value creation. The conclusions of this paper provide empirical evidence for the formulation of policies to promote the development of digital economy and enhance the status of GVC.
