我国各行业国际产品内贸易发展水平——基于垂直专业化指数法的测算

The Measurement of the Vertical Specialization Share of Intra-product Trade in each Industry of China

当前国际产品内贸易发展水平的测度主要包括联合国广义分类法(BEC)、加工贸易替代法以及垂直专业化指数法(VSS)。以VSS方法计算的结果表明,近年来,我国初级产品部门和资源密集型行业国际产品内贸易水平都呈下降趋势;高技术部门和劳动密集型行业的产品内贸易水平提升较快;服务贸易内各行业的国际垂直分工也有大幅度提升。

Vertical specialization share （VSS） is a precise method to measure the development of intra-product trade. By using this method of measurement, this paper finds that in China the level of intra-product trade in primary-product manufacturing and resource-intensive industries declines in recent years while that in high- technology and labor-intensive industries increases. In addition, the VSS in service industries rises quickly.
