中国参与国际垂直专业化分工程度的再度量——基于黑田法的研究

Measurement on China's Participation in Vertical Specialization——Based on Kuroda Method

基于现有的投入产出表数据,运用黑田法对其他相邻年份的直接消耗系矩阵进行序列外推,并以此为基础采用Hummels等(2001)的垂直专业化程度指标(VSS指标)计算我国总体及行业VSS值。结果显示:样本期内中国总出口中的垂直专业化程度上升迅速,从1990年的11.13%上升到2010年的26.79%,垂直专业化程度的提升主要通过进口日韩及东盟中间投入品的增加实现;各行业垂直专业化程度在样本期内均呈现上升趋势,垂直专业化程度的加深主要发生在资本(技术)相对密集的行业,劳动(自然资源)密集型行业的垂直专业化程度相对较低且提升幅度较小。

Based on the existing data of input - output tables, we adopt Kuroda method to deduct the direct consumption of matrix of the other adjacent years, and use the vertical specialization index （VSS index） developed by Hummels et al. （2001） to calcu-late China＇ s overall and industry VSS. The results showed： In the sample period, China＇s total export in the vertical special-ization is rising rapidly, up from 11.13% in 1990 to26.79% in 2010, and vertical specialization degree was promoted main-ly through Japan, South Korea and ASEAN import intermediate inputs increasing. The degree of industry vertical specializa-tion in the sample period showed a rising trend, but the degree deepen occurs mainly in capital （ Technology ） relatively in-tensive industry, labor （ natural resources） intensive industry is relatively low.
