摘　　要：稳步推进以制度型开放为核心的高水平开放,是助力构建新发展格局的重要举措。基于2012—2021年55个国家面板数据,采用PSM-DID考察方法CPTPP对成员国与非成员国数字服务贸易进出口的异质性影响。研究表明:CPTPP显著促进成员国数字服务贸易出口和进口,且对进口的影响程度较大;CPTPP对发达国家数字服务贸易的促进作用大于发展中国家;CPTPP显著影响金融服务业,电信、计算机和信息服务业,个人文化娱乐服务业及其他商业服务业贸易;CPTPP对发达国家知识产权使用服务业出口有促进作用,但对保险和养老服务业的影响效应尚未完全发挥。Steadily promoting high-level opening-up centered on institutional opening is an important measure to assist in building a new development pattern.Based on panel data across 55 countries from 2012 to 2021,the study employed the Propensity Score Matching Difference-in-Differences(PSM-DID)to examine the heterogeneous impacts of the CPTPP on digital services trade imports and exports among member countries versus non-member countries.The study showed that the CPTPP significantly promoted both the export and import of digital services trade among member countries,with a more pronounced impact on imports.The CPTPP’s facilitative effect on digital services trade was greater for developed countries than for developing countries.The CPTPP had a significant impact on financial services,telecommunications,computer and information services,personal cultural and entertainment services,as well as other commercial services.The CPTPP also boosted the export of the use of intellectual property services from developed countries,while its impact on the insurance and pension services has yet to be fully realized.
