Abstract: As a representative of the high-end manufacturing industry, the development of the integrated circuit industry has great strategic significance and development potential for the Beijing-Tianjin-Hebei urban agglomeration. To study the internal connection between the urban grade and the resilience of the integrated circuit value chain in the Beijing-Tianjin-Hebei urban agglomeration. With 2013-2022 as the study period, Using the data of 33 listed IC companies in Beijing, Tianjin and Hebei, The empirical analysis, using the generalized least squares method (FGLS) with fixed effects, The results show that megacities have a 27.84% positive impact on the resilience of the IC value chain, Greater than the 24.37% and 14.60% effects in megacities and type I cities, The interaction effect between variables suggests that, The interaction effect between type I cities and enterprise size will have a 21.52% positive impact on the resilience of the IC industry value chain, To be greater than the impact of 14.41% of megacities and19.35% of megacities, At the same time, the interactive effect of city level and management ability will also have a good promoting effect on the resilience of the IC value chain.

摘要: 集成电路产业作为高端制造业的代表,其发展对京津冀城市群具有极大的战略意义和发展潜力。研究京津冀城市群中城市等级与集成电路价值链韧性之间的内在联系。以2013-2022年为研究期限,利用京津冀33家集成电路上市公司数据,采用具有固定效应的广义最小二乘法(FGLS)进行实证分析,结果表明:超大城市对集成电路价值链韧性产生27.84%的正向促进影响,大于特大城市和Ⅰ型大城市产生的24.37%和14.60%的影响,变量之间的交互效应表明,Ⅰ型大城市与企业规模的交互效应会对集成电路产业价值链韧性产生21.52%的正向影响,要大于超大城市的14.41%和特大城市的19.35%产生的影响,同时城市等级与经营能力的交互效应也会对集成电路价值链韧性产生良好的促进效应。
