摘　　要：把握数字化发展新机遇,提升国内价值链分工水平,对于挖掘国内市场潜力、畅通国内大循环具有重要意义。本文构建了数字经济发展综合评价体系,并基于2012年、2015年和2017年中国30个省份(市、自治区)的多区域投入产出表测算得到国内价值链分工参与度及前向、后向参与度,分析了数字经济发展对国内价值链分工水平的影响。实证结果表明,数字经济发展有助于提升国内价值链分工水平,促进前向和后向分工协调发展。机制检验结果表明,数字经济发展通过技术促进、规模经济和消费升级效应对国内价值链分工水平产生显著的正向作用。差异性分析结果表明,数字经济发展对中西部地区、上游分工环节以及制造业行业价值链分工水平的促进作用更显著。本文的研究结论为改善区域发展失调、价值链分工上游垄断下游过度竞争以及制造业技术水平不足等情况提供了经验借鉴。It is significance to grasp the opportunities of digital development and improve the national value chain for tapping the potential of the domestic market and smoothing the domestic circulation. This paper empirically analyzes the impact of digital economy on the national value chain by building a comprehensive evaluation system based on the multi-regional input-output tables of 30 provinces in 2012, 2015 and 2017. The result shows that the development of digital economy is conducive to improving the national value chains and its forward and backward division. The mechanism test results show that digital economy has great influence on the national value chains through technology promotion, economy scale and consumption upgrading effects. Heterogeneity test reflects that digital economy plays a more significant role in promoting the midwest region, the upstream division sector and the manufacturing industry. This research provides an experience for improving the situations including imbalance of regional development, the production status of upstream monopoly and downstream excessive competition and low level of manufacturing technology.
