摘要
本文在借鉴国内外关于垂直专业化研究文献的基础上,计算了中国19个工业部门在1992~2003年期间的国内销售产品和出口贸易的垂直专业化程度。结果发现各行业的两个垂直专业化的平均比率都在1~10%之间,且数值比较接近,绝大多数行业的垂直专业化程度随着时间的推移而逐步提高。此外,本文还计算了分行业的产品国内技术含量,并通过计量检验考察了它与垂直专业化程度之间的关系,结果表明,在其他条件不变的前提下,工业行业的产品国内技术含量越低,其垂直专业化程度越高。
This paper estimates the vertical specialization ratios of domestic product sales and exports in 19 Chinese industrial sectors during 1992 to 2003,on the basis of the literature review on vertical specialization.The result indicates that the two vertical specialization ratios,which are between 1 and 10 percentage on average,are very closed,and the ratios of almost industrial sectors are gradually increasing.In addition,the paper calculates the domestic product technological contents(DTC) of industrial products sectors,and studies the relationship between vertical specialization ratio and DTC by an econometrical model.The result shows that as for Chinese industrial sectors,when others being equal,the lower the DTC is,the higher the vertical specialization ratio will be.
