服务贸易协定、条款深度与出口效率——来自高技术产业的证据

Service Trade Agreements,Depth of Provisions and Export Efficiency——Evidence from the High-Tech Industry

基于高技术产业的出口数据,本文采用随机前沿引力模型测算服务贸易协定缔约国的出口效率,实证考察了服务贸易协定条款深度对缔约国出口效率的影响。研究结果表明:(1)增加服务贸易协定条款深度可以显著提升缔约国的出口效率。(2)技术溢出效应、资源配置效应和需求规模效应是服务贸易协定条款深度影响缔约国出口效率的重要渠道。(3)服务贸易协定条款深度增加带来的出口效率提升作用在发达国家向发展中国家出口以及发展中国家向发展中国家出口的过程中更加突出。(4)服务贸易协定的生效年限越长,其条款深度的增加对出口效率的提升作用越大。

Based on the export data of high-tech industries,in this paper,the stochastic frontier gravity model is used to measure the export efficiency among the signatories of the trade in services agreement,and the influence of the depth of the provisions of the trade in Services agreement on the export efficiency of high-tech products is empirically investigated.The results show that:(1)increasing the depth of service trade agreement clauses can significantly improve the export efficiency of high-tech industries in contracting countries.(2)Technology spillover effect,resource allocation effect and demand scale effect are important channels through which the provisions of trade in services agreement deeply affect the export efficiency of the contracting parties.(3)The increased efficiency of exports brought about by the depth of the provisions of the Trade in Services agreement is more prominent in the process of exports from developed countries to developing countries and from developing countries to developing countries.(4)The longer the entry into force period of a service trade agreement is,the greater of the effect on increasing the depth of its provisions of improving export efficiency.
