| 基于全球价值链上下游关系，构建全球数字服务业技术跨国前后向溢出两类网络，运用复杂网络分析法从整体、局部社团和个体层面探究数字服务业技术跨国溢出网络的时空演化特征。结果表明：两类溢出网络规模不断扩大，溢出效率不断提高，但网络分布较不均匀，存在明显的集聚效应和“小世界”特征，且从德国、美国、英国和卢森堡主导逐渐转变为中国、美国、德国和卢森堡共同主导；中国在两类网络中虽然具有较强的直接影响力、反控制力及波及影响力，但中介控制力明显弱于美国、德国和卢森堡；从溢出路径看，中国香港向中国内地的前后向溢出规模最大，卢森堡向英国和德国等欧洲经济体的前后向溢出规模较大；从溢出关联看，中国、美国和日本等亚太经济体大多属于主受益板块，在网络中扮演“吸收者”角色，而中国香港、新加坡以及奥地利、瑞士、卢森堡等多数欧洲经济体属于双向溢出或主溢出板块，在网络中担任“奉献者”角色。 |

| Abstract: |
| Based on the upstream and downstream relationship of global value chain, this paper constructs two types of global digital service industry technology cross-border spillover networks, and explores the temporal and spatial evolution characteristics of digital service industry technology transnational spillover networks using complex network analysis method from the overall, local community and individual levels. The results show that the scale of the two types of spillover networks continues to expand, and the spillover efficiency continues to improve, but the distribution of the networks is not uniform, there are obvious agglomeration effects and“small world” characteristics. The network pattern was dominated by Germany, the United States, the United Kingdom and Luxembourg, and gradually changed to China, the United States, Germany and Luxembourg. Although China has strong direct influence, counter-control and spread influence in the two types of networks, the intermediary control is significantly weaker than that of the United States, Germany and Luxembourg. In terms of spillover paths, China Hong Kong has the largest spillover to Mainland China , Luxembourg has the largest spillover to European economies such as the United Kingdom and Germany. From the perspective of spillover correlation, most Asia-Pacific economies such as China, the United States and Japan belong to the main beneficiary sectors and play the role of“absorbers” in the network, while China Hong Kong, Singapore and most European economies such as Austria, Switzerland and Luxembourg belong to the two-way spillover or main spillover plate and play the role of "contributors" in the network. |
