摘　　要：以数字服务为核心、数字平台为载体的数字贸易已经成为国际贸易往来的新引擎,不仅创新了贸易方式,也对贸易成本的降低起到积极作用。本文运用熵值测算了2008-2021年RCEP伙伴国数字贸易发展水平,根据贸易成本测度模型测算我国与RCEP伙伴国的双边贸易成本,并基于引力模型实证研究前者对后者的影响效应。研究发现:(1)RCEP伙伴国数字贸易发展水平逐年上升但国家间差距逐渐拉大;除马来西亚外,其余国家与我国的双边贸易成本呈波动下降趋势;(2)RCEP伙伴国数字贸易发展水平的提高对我国与其双边贸易成本有显著降低效应,结论经过内生性处理和稳健性检验后依然成立。建议依托RCEP伙伴国数字贸易发展,加强我国与其在数字贸易领域全方位合作,积极打造区域内数字流动安全规则。Digital trade with digital services as the core and digital platform as the carrier has become a new engine of international trade transactions,which not only makes innovations in mode of trade,but also plays a positive role in reducing trade costs.This paper measures the development level of digital trade in RCEP partner countries through computing entropy value from 2008 to 2021,and the bilateral trade costs between China and RCEP partner countries are measured using the trade cost measurement model.Furthermore,the effect of the former on the latter is empirically studies based on the gravity model.It is found that:the level of digital trade development in RCEP partner countries has increased year by year but the gap between them has gradually widened.Except for Malaysia,the bilateral trade costs between RCEP countries and China show a fluctuating downward trend.The rise in the level of digital trade development in RCEP partner countries has a significant effect on lowering bilateral trade costs between them and China,and the conclusions are still valid after both endogeneity and robustness test.It is suggested that China should strengthen all-round cooperation with RCEP partner countries in digital trade,and actively create security rules for digital flows in RCEP region,relying on the development of digital trade in them.
