根据经验统计表明,服务贸易与货物贸易在差额变动和方向上存在替代性特征。文章以Dornbush等(1977)为基础考虑一个两国开放经济的李嘉图连续统模型,分析各国不同部门劳动生产率变化与服务成为贸易品两个因素对贸易形式和贸易差额变化的影响。研究表明在服务可贸易条件下,不同国家在服务部门和货物生产部门劳动生产率发生的相对差异变动,是导致各国货物或服务贸易差额关系变化的决定因素。而中国-OECD(1982-2004)的劳动生产率及贸易差额的数据检验,也较好地支持了此结论。
According to empirical statistics, service trade and trade in goods in the balance of changes and the direction of the existence of alternative features. Based on Dornbush et al. (1977), the paper considers a Ricardo continuum model of open economy in two countries and analyzes the influence of changes in labor productivity and services becoming tradables on changes in trade forms and trade balances in different countries. The study shows that under the conditions of service trade, the relative differences in labor productivity of service sectors and goods production sectors in different countries are the determinants of changes in the balance of trade in goods and services. However, the data test of China-OECD (1982-2004) on labor productivity and trade balance also supports this conclusion.
