摘　　要：数字技术发展为贸易便利化革新带来重大机遇,数字贸易便利化成为全球价值链升级的重要抓手。文章基于2007—2021年“一带一路”沿线国家数据,构建数字贸易便利化评价指标体系,从高度和广度两个维度刻画全球价值链升级,探究数字贸易便利化对全球价值链升级的影响。研究发现:数字贸易便利化显著促进“一带一路”沿线国家全球价值链升级,且具有非线性递增效应;数字安全、数字基础设施分别是提升全球价值链高度和广度的关键因素,数字贸易便利化对制造业和发达国家全球价值链升级作用更大;促进技术溢出和强化市场竞争是数字贸易便利化推动全球价值链升级的重要机制。The advancement of digital technology offers substantial opportunities for enhancing trade facilitation through innovation,with digital trade facilitation emerging as a critical driver for the upgrading of the Global Value Chain(GVC).This essay utilizes data from countries participating in the Belt and Road Initiative spanning the period from 2007 to 2021 to establish an evaluation index system for digital trade facilitation.It assesses the enhancement of the GVC in terms of both height and scope,investigating the influence of digital trade facilitation on the advancement of GVC.Findings:The impact of digital trade facilitation on the upgrading of GVC in Belt and Road countries is substantial,demonstrating a non-linear incremental impact.Digital security and digital infrastructure are key factors in enhancing the intensity and scope of GVC.Particularly,the influence of digital trade facilitation on GVC upgrading is more pronounced in the manu⁃facturing industry and in developed economies.The promotion of technological spillover and the reinforcement of market competition are essential mechanisms through which digital trade facilitation drives the advancement of GVC upgrading.
