基于投入产出表的中国纺织服装业垂直分工测度研究

Research on Measurement of Vertical Specialization of Chinese Textile and Apparel Industry that Based on the Input-output Table

对Hummels等人建立的国际垂直专业化分工测度方法进行了完善与拓展,利用行业垂直专业化分工公式测算了全国及江苏、浙江、广东、上海纺织服装业的垂直专业化分工。结果显示,纺织业的垂直专业化分工较高,服装业的垂直专业化分工较低;广东、上海的垂直专业化分工较高,而浙江、江苏的垂直专业化分工较低。垂直分工过高会对国际市场产生过度依赖性,过低又会导致国际分工参与不足,因此需要制定相关政策来调整中国纺织服装业的垂直专业化分工程度。

This article improves and expands the measurement of vertical specialization established by Hummels at first. Then calculats vertical specialization index of the textile and apparel industry of national, Jiangsu, Zhejiang, Guangdong, Shanghai provinces. The results show that the vertical specialization index of the textile industry is higher than the apparel industry, the vertical specialization index of Guangdong, Shanghai provinces are higher than Jiangsu,Zhejiang provinces. High index of vertical specialization will have excessive dependence to the international market, and low index of vertical specialization will lead to insufficient of participation of the international division of labor. So it is needed to formulate policies to adjust the extent of vertical specialization of textile and apparel industry nationally.
