摘　　要：本文选取2014—2018年我国对47个国家IT信息服务附加值出口数据,检验GVC分工地位、IT信息服务业贸易限制、数字贸易限制以及美国因素的影响。结果表明:我国IT信息服务附加值出口受到分工地位的抑制和进口溢出效应的促进作用;IT信息服务业贸易限制和数字贸易限制都构成IT信息服务附加值贸易的壁垒;美国贸易份额的挤出效应仅存在于IT信息服务业全球价值链中,中美之间IT信息服务业规则差异和数字贸易规则差异则更为明显地抑制了我国对其他国家的IT信息服务附加值出口;在制造业全球价值链中,我国IT信息服务业较少受分工地位和服务贸易限制措施的抑制作用,并更多地获得进口溢出效应和美国贸易份额的促进作用。This paper selects data on China's value-added exports of IT information services to 47 countries from 2014-2018 to test the effects of GVC division of labor status,IT information services trade restrictions,digital trade restrictions,and U.S.factors.The results show:China's value-added exports of IT information service is restrained by the division positions in GVCs and promoted by the import spillover effect.Both service trade restrictions on IT information service and digital trade constitute barriers to IT information service value-added trade.The crowding out effect of U.S.trade share only exists in the IT information service GVCs.The restrictions heterogeneities of IT information service and digital trade between China and the U.S.inhibit China's value-added exports of IT information services to other countries.Participating in the GVCs of manufacturing,IT infor⁃mation service industry can be less restrained by their positions in GVCs and service trade restrictions,and can obtain the import spillover effect and the promotion of the U.S.trade share to a greater extent.
