服务贸易技术含量与工业生产率——基于跨国面板数据的实证研究

The Technical Content of Trade in Service and Industrial Productivity:An Empirical Study Based on Multinational Panel Data

文章基于进口和出口二维视角探讨了服务贸易技术含量对工业生产率的不同作用机制,并利用56个国家(或地区)2004~2013年的跨国面板数据进行实证检验。结果表明,服务贸易进出口技术含量均能有效促进工业生产率提升,且进口技术含量的生产率效应强于出口技术含量;技术和知识越密集的进口服务品,其技术含量增加对工业生产率的拉动力度越强;而高技术服务品的出口技术含量对工业生产率的影响程度不及中技术服务品,仅略高于低技术服务品。

This paper explores the different function mechanisms between the technical content of trade in service and industrial productivity based on a two-dimensional perspective of import and export. And it conducts an empirical study by using the transnational panel data of 56 countries（ or regions） from 2004 to 2013. The result shows that the technical content of service import and export can effectively promote industrial productivity, and the technical content of service import has a stronger productivity effect than the technical content of service export; service imports, which are more technology and knowledge-intensive, have a stronger effect on boosting industrial productivity when their technical content gains, while the technical content of high-tech service exports has a less effect on industrial productivity than mid-tech exports, only slightly stronger than low-tech exports.
