The industrial agglomeration of digital economy is an important support for promoting green technology innovation, which is of great strategic significance for realizing ecological protection and high-quality development in the Yellow River Basin. Based on the data of digital economy enterprises in 78 prefecture-level cities in the Yellow River Basin from 2011 to 2022, this study used the kernel density estimation and location entropy methods, reciprocal of Herfindahl-Hirschman index, and the two-way fixed effect model to explore the temporal dynamics, spatial patterns, agglomeration characteristics of specialized agglomeration and diversified agglomeration, and their impact on green technology innovation. The results show that: 1) From 2011 to 2022, the number of digital economy enterprises in the Yellow River Basin increased from 36400 to 402100, an increase of about 10.05 times. 2) The spatial distribution of kernel density changed from single-core or dual-core to multi-cores in individual province. The lower reaches formed a contiguous development trend, and the middle and upper reaches showed a scattered distribution of high-value agglomeration areas. The regional differences between specialized agglomeration and diversified agglomeration of digital economy industry were significant, and the overall distribution was high in the east and low in the west. 3) The influence of specialized agglomeration and diversified agglomeration of digital economy industry on green technology innovation showed obvious heterogeneity. Specialized agglomeration had a positive effect on green technology innovation, while diversified agglomeration inhibited green technology innovation in the basin to a certain extent, and there were significant differences in the upstream, midstream, and downstream industries. Based on these results, corresponding countermeasures and recommendations were put forward from the aspects of infrastructure development, industrial planning and layout, and regional cooperation, in order to promote the deep integration of digital economy industry and green technology innovation, and help the high-quality development of the Yellow River Basin.
