The impact of digital infrastructure on industrial chain resilience: evidence from China's manufacturing

The improvement of digital infrastructure is a key support for enhancing the industrial chain resilience and ensuring its normal operation under various unconventional disturbance risks. This paper uses panel regression model, quantile regression model, panel threshold model, and Spatial Durbin Model to explore the internal mechanism and spatial impact effect of digital infrastructure construction on China's manufacturing industry chain resilience. Research found that digital infrastructure does have a positive impact on industrial chain resilience. The estimation results of heterogeneity indicate that compared with underdevelopment or regions with tight finance, the positive promotion effect of digital infrastructure on the manufacturing industry chain in regions with developed economies and abundant regional finance is smaller. In regions with relatively abundant human capital, it is easier to promote the positive effect of digital infrastructure on industrial chain resilience. This paper not only enriches the quantitative research on industrial chain resilience, but also expands the research boundaries of industrial chain resilience. And it provides policy inspiration for promoting digital infrastructure and industrial chain resilience development in a coordinated manner.
