摘　　要：伴随着互联网、云计算、区块链等数字技术在全球范围内应用广度与深度的不断拓展,数字经济逐渐成为重塑国际贸易的主要力量。本文利用UIBE全球价值链数据库和WIOD数据库,构建2000至2014年42个国家27个服务业的国内增加值贸易网络,研究数字化投入对其在服务贸易网络中地位的影响。研究显示:服务业数字化投入有利于提高行业在服务贸易网络中的地位。从影响机制看:服务业数字化投入主要通过降低服务贸易成本、缓解资源错配、有效替代部分劳动力等渠道来提高国家在服务贸易网络中的地位。异质性结果表示:服务业数字化投入水平的提升对不同国家的影响效果存在差异,加大数字化投入更有利于提高发展中国家服务业在贸易网络中的地位;相较于国内数字化投入,服务业在贸易网络中的地位提升受国外数字化投入的影响更大;数字化投入对服务贸易网络中消费性服务业地位的提高效果更加显著。本文实证结果为中国如何在数字化浪潮中实现产业升级,提高自身在服务贸易中的地位提供了有益启示。As digital technologies such as the Internet,cloud computing,and blockchain around the world are applied in a deepened and broadened way,the digital economy has gradually become the main driving force for reshaping the international trade.This paper uses UIBE Global Value chain database and WIOD database to build the domestic value added trade network of 27 service industries in 42 countries from 2000 to 2014,studying on the impact of digital input on the service trade network status.The research shows that digital investment in service industry is conducive to improving the status of the industry in the service trade network.From the perspective of impact mechanism,digital investment in service industry mainly improves the status of the country in the service trade network by reducing the cost of service trade,alleviating resource mismatch,effectively replacing part of labor force and so on.Heterogeneity results are as follows:the increase of digital investment in service industry has different effects on different countries,and increasing digital investment is more conducive to improving the status of developing countries’service industry in the trade network;compared with domestic digital input,the promotion of service industry’s status in trade network is more influenced by foreign digital input;digital input has a more significant effect on improving the status of consumer service industry in the service trade network.The empirical results of this paper provide reference for China to realize industrial upgrading and improve its position in service trade in the wave of digitalization.
