国际产业趋同与差异研究——来自非竞争型投入产出表的证据

The Research on the Convergence and Differences of the International Industries——the Evidence from the Non-competitive Input-output Tables

由于竞争型投入产出表在分析国际产业趋同和差异研究中会造成诸多不便,因此,本文在采用OECD提供的2002、2006以及2009年版本的非竞争型投入产出数据库以及2008年版本的双边贸易数据库的基础上,利用Hummels等人建立的垂直专业化份额指标,并通过界定价值增值能力指标和设定价值增值驱动力假说,从垂直专业化、价值增值能力和产业竞争力三个方面研究了22个国家、17个行业的国际产业趋同和差异问题。研究结果表明,不同技术类型的产业发展呈现不同的特点,发达国家与发展中国家在国际分工的表现也有所差异,发展中国家尤其是中国在参与垂直专业化分工中亟需解决其低附加值产出的问题。

To avoid the defect of the competitive input-output tables on the analysis of the international industrial convergence and difference, this paper adopts the 2002, 2006 and 2009 version of the non-competitive input-output databases and the 2008 version of BTD databases offered by the OECD, based on the calculation method of vertical specialization share by Hummels etc, and through improving the index of value-added and setting the value added driving hypothesis,we study the con- vergence and differences in the 17 industries of 22 countries from three aspects, including vertical specialization, value added and industrial competitiveness. The results indicate that different technical types of industries show different characteristics, and there are different characteristics between the developed countries and developing countries in the international division of labor. The developing countries, especially for China, should solve the problem of low value-added output urgently in the vertical specialization.
