摘　　要：基于2011—2021年中国与56个共建“一带一路”国家的面板数据,采用百度指数实证检验互联网搜索对中国与共建“一带一路”国家服务贸易规模的影响。研究结果表明:(1)互联网搜索能够促进中国与共建“一带一路”国家服务进出口贸易额的增加,对中国与非共建“一带一路”国家服务进出口贸易的影响并不明显;(2)“一带一路”倡议有利于扩大中国与互联网关注度较低经济体的服务贸易规模;(3)互联网搜索有助于提升中国对共建“一带一路”国家生产性服务贸易出口额与进出口总额,对数字服务贸易的影响并不明显;(4)数字基础设施建设水平和服务业结构占比是互联网搜索对服务贸易规模产生异质性影响的原因;(5)互联网搜索主要通过克服地理距离渠道实现双边服务贸易规模的扩大。In the era of the digital economy,Internet search is an essential way for enterprises and individuals to reduce information asymmetry.Based on the Baidu search index and Baidu information index of various economic entities from 2011 to 2021,this paper empirically examines the impact of Internet search on the scale of bilateral service trade between China and 56 countries along the Belt and Road.The findings reveal that Internet search can promote the bilateral service import and export trade volume be-tween China and countries along the Belt and Road,with little impact on that between China and the rest countries.In addition,the Internet information index also promotes the bilateral service trade import and export volume be-tween China and countries along the Belt and Road.The results of the difference-in-differences-in-differences(DDD)estimation show that the Belt and Road Initiative promotes the expansion of service trade scale between China and countries with low Internet attention.The regression results considering the breakdown of trade in serv-ices show that Internet search can promote China’s exports and total imports and exports of productive services with countries along the Belt and Road,with little impact on digital services trade.Heterogeneity analysis indicates that digital infrastructure and the service structure in trade partner countries are the reasons for the heterogeneous im-pacts of Internet search on the scale of service trade.Mechanism test indicates that Internet search mainly expands bilateral service trade scale by overcoming geographical distance.Based on the development of Internet search engines and the development of the digital economy,it is recom-mended to deepen the following aspects to promote the high-quality development of service trade with countries along the Belt and Road and contribute to better practice of the Belt and Road Initiative with Chinese wisdom.First,the construction of digital infrastructure should be strengthened to enhance Internet penetration and increase In
