摘　　要：基于2012年、2015年、2017年的《中国区域间非竞争型投入产出表》,运用增加值分解模型,从双循环价值链嵌入度、双循环价值链嵌入位置和出口增加值流向三个方面分析31个省级区域嵌入双循环价值链的特征,结果发现:各省份的国内价值链嵌入度高于全球价值链嵌入度,且大多数省份国内价值链嵌入度呈上升趋势,表明省域经济活动更多地依赖于国内价值链,中西部省份在双循环价值链中处于相对上游位置,沿海省份处于相对下游位置,且2012年至2017年各省份的双循环价值链嵌入位置在向中游集聚之后向中下游攀升,北京、广东、浙江、江苏、上海等是出口增加值的主要流入地,而河北、湖北、湖南、海南和青海等是出口增加值的主要流出地,沿海省份成为连接国内循环与国际循环的重要纽带。因此,优化提升双循环价值链的重点在于加强国内价值链,要协调区域专业化分工,促进产业链上下游的协同发展,各省级区域要积极推动自身的产业链价值链供应链升级,尤其是东部发达省份应帮助其他省份提升产业发展水平。Research integrating dual circulation with the value chain is notably scarce,particularly lacking analyses on the extent of value chain integration among different provinces and their roles and connections within the value chain.This paper focuses on the 31 provinces of China,using regional input-output tables from 2012,2015,and 2017 to construct indicators for evaluating provincial-level regional integration into the dual circulation value chain.It analyzes the characteristics of provincial regions under the integration of the dual circulation value chain.Results reveal that:①Overall,most provinces have higher integration into domestic value chains than global ones,indicating a greater reliance on domestic value chains.However,downstream regions in the value chain are fewer in number,with significant disparities in downstream integration,while upstream regions show a tendency towards excessive concentration,posing a threat to the stability of the value chain.②In terms of integration features,the division of labor within the value chain is gradually shifting from single-chain circulation to dual-chain circulation.Western and central regions serve as the midstream to upstream of the dual circulation value chain,processing raw materials and transferring intermediate goods to coastal regions through complete supply chain networks.Coastal regions are gradually ascending from the midstream to downstream of the value chain,shifting from semi-finished to finished goods processing,and exporting final products to western,central regions,and overseas.③Spatially,the integration between coastal and western-central regions is more pronounced,with coastal regions maintaining close ties with western-central regions with high network density,providing significant value-added,hence,the local value-added content in coastal regions’exports is not notably high.Compared to previous literature,this paper adopts a novel perspective by unifying dual circulation with the value chain within one research framework,focusing on analy
