地区参与全球价值链、国内区域价值链、省内价值链的程度测算及比较分析

Measuring and comparative analysis of the degree of Regional Participation in Global Value Chain,Domestic Regional Value Chain and Provincial Value Chain

从价值链视角认识地区分工地位并探寻升级路径,对提升全国整体竞争力具有重要的现实意义。本文将中国区域间投入产出表嵌入到世界投入产出表中,构建IRIOT-WIOT投入产出表,利用价值链分解方法,测算全国30个省市区参与全球价值链、国内价值链和省内价值链的程度。结果发现:湖北、四川等中西部省市经济以省内循环为主,对国内和国际分工参与程度很低;上海、北京、广东和江苏四个省市全球价值链参与度很高,但分工地位不高,浙江全球价值链参与度和分工地位都较高;内蒙古、河北、新疆等省区国内价值链参与度较高。借鉴联合国贸易和发展会议(UNCTAD)价值链升级理论,本文针对不同省区市的特点提出不同的地区价值链升级路径。

It is of great practical significance to understand the regional division of labor status and explore the upgrading path from the perspective of value chain to improve the overall national competitiveness.This paper embeds the China interregional input-output table into the world input-output table to construct the IRIO-WIOT input-output table,and using the value chain decomposition method,measure the degree of participation of 30 provinces and cities in the global value chain,domestic value chain,and provincial value chain.The results showed that:the economy of central and western provinces and cities such as Hubei and Sichuan is mainly driven by intra provincial circulation,and their participation in domestic and international division of labor is very low.Shanghai,Beijing,Guangdong,and Jiangsu have a high level of participation in the global value chain,but their division of labor status is not high.Zhejiang has a high level of participation and division of labor in the global value chain.Inner Mongolia,Hebei,Xinjiang have a high level of participation in the domestic value chain.Drawing on the value chain upgrading theory of the United Nations Conference on Trade and Development(UNCTAD),this paper proposes different regional value chain upgrading paths based on the characteristics of different regions.
