摘　　要：本文在社会网络分析框架下,利用时间指数随机图模型(TERGM)探索数字贸易规则对高技术产品贸易依赖关系的影响。研究发现:数字贸易规则的深度对于高技术产品贸易依赖关系没有显著影响,但数字贸易规则中的核心经济体更容易接收到来自其他经济体高技术产品的贸易依赖关系,从而在高技术产品贸易依赖网络中处于优势地位。通过对条款的异质性分析发现:签订的双边数据流动条款和服务贸易条款存在创新的溢出效应,可以缩小双方创新能力和技术水平的差距,减弱该贸易依赖关系;而双边深度知识产权保护条款则会促进双边高技术产品贸易依赖关系的形成;电子商务条款深度对高技术产品贸易依赖关系的影响不显著。从绝对数量来看,四类子条款签订数量和深度推动了经济体创新水平的提升,对于经济体接收贸易依赖关系均有显著正向影响。Digital trade rules not only serve the development of digital trade,but also have an impact on high-tech product trade from aspects such as trade costs and innovation.This paper attempts to explore how digital trade rules affect the trade of high-tech products by measuring trade dependency relationships.This paper constructs a high-tech product trade dependency network within the framework of social network analysis by measuring the high-tech product trade dependency relationship between economies.It also constructs a digital trade rule network by assessing the relationships and terms of digital trade rules among different economies,and evaluates the position of each economy in the digital trade rule network.Based on the constructed network,the Temporal Exponential Random Graph Model is used to explore the impact of digital trade rules on high-tech product trade dependency network from two aspects:bilateral relationships and individual positions in the network.The results indicate that the depth of digital trade rules does not have a significant impact on the formation of high-tech trade dependency network.However,core economies within the digital trade rules network are more likely to receive trade dependence on high-tech products,thus placing them in a more advantageous position in the high-tech product trade dependency network.The analysis of the heterogeneity of the terms reveals that the data flow terms and service trade terms signed by both sides exhibit an innovative spillover effect,which can narrow the gap in their innovation capabilities and technological levels,and weaken the trade dependency relationship.Bilateral intellectual property protection clauses will promote the formation of bilateral high-tech product trade dependence.In contrast,the impact of the e-commerce terms is not significant.In terms of absolute quantity,all four types of sub-clauses promote the innovation level of an economy and have a significant positive impact on the economy's acceptance of trade dependence.The study clarifies th
