摘　　要：数字经济发展能够有效驱动产业创新发展、建设有序竞争市场环境、加速要素自由流动,进而跨越行政区划和地理客观因素限制,助力破除省际贸易壁垒和市场分割,促进全国统一大市场的建设和国内大循环的健康高效运行。基于此,本文运用价格指数法生成我国省际贸易壁垒指标,采用主成分分析法构建数字经济发展水平的指标体系,综合形成2013—2020年31个省份的面板数据。研究发现,数字经济发展水平对省际贸易壁垒的弱化效应较为显著,数字经济还能够突破行政和地理客观限制造成的贸易壁垒。本文深入分析、测试和检验了数字经济发展对省际贸易壁垒的影响效应,为建设更加高效规范、公平竞争、充分开放的全国统一大市场及实现共同富裕目标提供从数字经济角度切入的政策参考。Digital economy is considered to be a vital contributor to triggering innovation as well as development of industry, building up a better market environment with fair competition, accelerating the flow of economic factors of the market. All of these may lead to the decreasing of the interprovincial trade barriers and market fragmentation, not limited by the administrative and geographic disadvantages, which helps to achieve the goals of unified national market and smooth national circulation. Interprovincial trade barrier index calculated according to the retail price index, and digital economy development index founded upon “principal component analysis” is used in this article where all analyses are carried out based on the panel data of 31 provinces ranging from 2013 to 2020. Also robustness analysis is taken to make sure the conclusions are convincing and reliable. Our research finds out that digital economy does has a decreasing effect on interprovincial trade barriers, and it can also adjust the administrative and geographic restrictions which objectively brings about trade barriers. What this article has discovered may provide academia with more data and theoretical evidences of digital economy’s effects on interprovincial trade barriers, and hopefully may offer guidelines and enlightenment for policy making aiming at the unifying of national market with higher efficiency, fairer competition and deeper opening-up, and the forming the common prosperity.
