Abstract:

The Yellow River Basin is the main battlefield for consolidating poverty alleviation achievements and coordinating regional development. Its high-quality development urgently requires the strategic support of digital new infrastructure. Based on the provincial panel data of the nine provinces (autonomous regions) in the Yellow River Basin from 2013 to 2023, empirical tests show that digital new infrastructure significantly promotes the high-quality development of the Yellow River Basin, with the strongest promoting effect in the upstream provinces (autonomous regions). Moreover, the role of innovation infrastructure is greater than that of integration infrastructure, and the role of integration infrastructure is greater than that of information infrastructure. This conclusion remains significantly valid after a series of endogeneity and robustness tests. Mechanism tests indicate that technological innovation and industrial structure upgrading are important transmission channels for digital new infrastructure to promote the high-quality development of the Yellow River Basin. Moreover, the promotion of digital new infrastructure for the high-quality development of the Yellow River Basin will produce a positive spatial spillover effect. Heterogeneity tests show that digital new infrastructure has a more obvious promoting effect on the high-quality development of moderately resource-dependent provinces (autonomous regions) and provinces (autonomous regions) with medium human capital stock.

Key words: digital new infrastructure, high-quality development, Yellow River Basin, technological innovation, industrial structure upgrading
