This study integrates multi-source panel data of 27 cities in the Yangtze River Delta from 2011 to 2023. By constructing an economic geography composite spatial weight matrix and a nonlinear spatial panel model, this study analyzes the impact of the diffusion of digital inclusive financial information on industrial structure upgrading. The results show that: (1) digital financial inclusion exerts a significant direct effect and spatial spillover effect on industrial structure; (2) the local effect exhibits a \u201cU-shaped\u201d curve with an accelerating characteristic on the right side; the spatial spillover effect demonstrates an \u201cinverted U-shaped\u201d curve, revealing the transformation law and threshold effect of the diffusion and aggregation of digital financial information benefits; (3) digital payment and digital credit constitute the core information flows driving the coordinated upgrading of industries; and (4) entrepreneurial activity exerts a partial mediating effects, and exhibits a spatial mediating effect, while the technological innovation only demonstrates a significant local mediating effect. The findings provide quantitative evidence to support the optimization of the digital financial information ecosystem and the realization of coordinated industrial upgrading in the Yangtze River Delta.<\/jats:p>","DOI":"10.3390\/info17050510","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T13:53:24Z","timestamp":1779371604000},"page":"510","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Research on the Nonlinear and Spatial Effects of Digital Financial Information Flow on Industrial Structure Upgrading"],"prefix":"10.3390","volume":"17","author":[{"given":"Pengzhuo","family":"Wu","sequence":"first","affiliation":[{"name":"School of Mathematics and Data Science, Changji University, Changji 831100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mathematics and Data Science, Changji University, Changji 831100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guodong","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mathematics and Computing Science, Guilin University of Electronic Technology, Guilin 541002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e33711","DOI":"10.1016\/j.heliyon.2024.e33711","article-title":"Evaluating the moderating role of governance on the relationships between social inclusion, ICT infrastructure, and financial inclusion","volume":"10","author":"Bibi","year":"2024","journal-title":"Heliyon"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Li, Y.L., Wang, M.X., Liao, G.K., and Wang, J.X.
