本文基于2007—2017年中国区域间投入产出表和OECD全球投入产出表，通过编制划分数字和非数字贸易支撑部门的我国区域嵌入全球投入产出表，构建区域嵌入全球数字价值链（GDVC）的增加值测算框架，清晰直观地刻画我国各区域嵌入全球数字价值链的路径及其变动趋势。研究发现：我国参与全球数字价值链增加值主要来源于国外需求拉动型的单一GDVC分工，其次是我国国内数字价值链（NDVC）拉动型的混合GDVC分工。进一步研究表明，尽管区域间参与数字价值链的差距有所缩小，但地区差异性仍然存在，东部地区在全球数字分工中的参与度较高，而中部和西部地区的参与度相对较低。因此，在全球数字化转型不断加速的背景下，推动中部和西部地区更深层次地融入全球数字分工体系，合理有序引导全球数字分工向内陆地区梯度转移，是避免产生新的数字鸿沟和缩小区域发展差距的重要路径。

Based on China's interregional input-output tables and the OECD global input-output tables for 2007–2017, this article establishes a framework for measuring the value added of China's regional integration into the global digital value chain(GDVC) by compiling a global input-output table that embeds Chinese inter-regional input-output data and separates digital from non-digital sectors. It clearly depicts the path and changing trends of China's regional integration into the GDVC. The results show that the value added generated by China's GDVC participation is primarily derived from a single-GDVC division of labor driven by foreign demand, followed by a mixed-GDVC division of labor driven by China's national digital value chain(NDVC). Further evidence indicates that although interregional disparities in digital value chain participation have narrowed, substantial heterogeneity persists: the eastern region exhibits a higher level of engagement in global digital specialization, whereas the central and western regions remain less involved. Therefore, against the backdrop of accelerating global digital transformation, policy efforts should prioritize enabling deeper participation of the central and western regions in the global digital division-of-labor system and guiding an orderly, stepwise relocation of global digital activities toward inland areas, thereby preventing new digital divides and reducing regional development gaps.
