摘要
利用区域间投入产出表分析在全球价值链背景下数字经济对中国地区间产业链分工长度的影响.研究发现:互补品贸易下,地区间产业发展的联动效应较为显著,缩小样本地区间数字经济发展差异度,有助于延伸国内价值链长度.替代品贸易下,地区间产业链竞争关系较为显著,样本地区间数字经济发展差异度增强,会加剧地区间发展不平衡不充分现象,一定程度上妨碍国内价值链在相应区间合作延伸.畅通国内大循环下要特别注重发展"需求-供给"互补品贸易,扩大企业间交往频率,为扩大地区间产业链梯度转移创造良好外部条件;要利用好全球产业链密切分工的协作关系,努力做到脱钩不断链.为此,缩小中国地区间数字经济发展差异成为全球价值链在国内地区间延伸的关键.
Abstract
This article uses an interregional input-output table to analyze in depth and detail the impact of digital economy on the length of industrial chain division of labor in China's interregional industry in the context of global value chains.The research finds that under the trade of complementary goods,the linkage effect of interregional in-dustrial development is relatively significant,reducing the difference in the development of digital economy among sample regions is conducive to the extension of the length of China's domestic value chain.Under substitute trade,the competition relationship between regional industrial chains is more significant,and the difference in digital economy development between sample regions increases,which will exacerbate the phenomenon of uneven and insufficient de-velopment between regions and to some extent hinder the extension of domestic value chain cooperation between corresponding regions.
