中国制造业全球价值链位置的行业异质性及收敛性测度

中国制造业通过嵌入全球价值链参与国际分工,全球价值链位置演化呈现收敛趋势。利用TiVA数据库提供的数据,采用附加值贸易法对中国制造业全球价值链位置进行测度。结果发现,1995-2014年,中国制造业全球价值链位置演化经历了3个阶段(GVC1.0、GVC2.0、GVC3.0),在GVC1.0时期全球价值链位置不断下降,在GVC2.0时期全球价值链位置加速上升,在GVC3.0时期全球价值链位置稳步上升。构建全球价值链位置收敛计量检验模型,分别对中国制造业全球价值链位置的绝对σ收敛、绝对β收敛和条件β收敛进行检验。结果表明:中国制造业全球价值链位置演化存在绝对σ收敛、绝对β收敛和条件β收敛,但是中高技术和高技术制造业行业全球价值链位置演化存在绝对β发散和条件β收敛。研究结论可为促进我国制造业不同行业迈向全球价值链更高位置提供新证据。

Industry Heterogeneity and Convergence Measures of Global Value Chain Location in China's Manufacturing Industry

China's manufacturing industry participates in international division of labor by embedding global value chain, and the evolution of global value chain shows a convergence trend.Based on the data provided by TiVA database, this paper uses the method of value-added trade to measure the location of the global value chain of China's manufacturing industry.It is found that the location evolution of the global value chain of China's manufacturing industry experienced three stages (GVC1.0, GVC2.0 and GVC3.0) during 1995-2014.During the GVC1.0 period, the position of global value chain continued to decline; during the GVC2.0 period, the position of global value chain accelerated; during the GVC3.0 period, the position of global value chain steadily increased.Then building the measurement model of the convergence of global value chain position,and testing global value chain position of absolute σ convergence, absolute β convergence and conditional β convergence of China's manufacturing industry.The test results show that absolute σ convergence,absolute β convergence and conditional β convergence existing in the evolution of global value chain of Chinese manufacturing industry.However, the absolute β divergence and conditional β convergence exist in the location evolution of the global value chain in high-tech and high-tech manufacturing industries.The conclusion of the study provides new evidence for promoting China's manufacturing industries to move up the global value chain.
