生产者服务贸易的技术结构及其影响因素——基于技术附加值指标的研究

Technological Structure and Determinants of Producer Services Trade:An Empirical Study Based on the Index of Sophistication

文章采用技术附加值的核算方法对于2000-2010年全球范围内42个样本国家（地区）的生产者服务贸易数据进行分析，并采用面板数据模型对各国生产者服务贸易技术结构指标进行实证检验。针对服务项目层面的研究表明，除计算机信息服务以外的生产者服务在全球范围内的生产分散程度仍然较低，其生产过程主要集中于少数发达国家。针对国家层面的研究表明．服务全球化是影响发展中国家生产者服务贸易技术结构的重要因素。发展中国家服务业参与全球价值链分工的过程中，其生产者服务贸易技术结构会经历先恶化再优化的V型变化过程。

The paper uses the index of technological sophistication to study the producer services trade of 42 economies from 2000 to 2010, and based on the model of panel data, tries to make an empirical test on the technological structure of producer services exports of the economies. The study on services items indicates that the fragmentation of producer services has not developed rapidly, except for the computer and information service. The production process of producer services is also located in a few developed countries principally. The study on economies shows that the globalization of services is a key factor in developing countries＇ technological structure of producer services trade. During the process of a developing country＇s joining of service sectors in the global value chain, its technological structure experiences a trend of ＂first fall, and then rise＂, and emerges in a ＂V＂ pattern.
