Does digital industry agglomeration bring substantive green innovation?—Empirical analysis of SPDM and PTR models based on spatiotemporal dual fixation

Abstract Digitally driven green high‐quality development is an essential way to realize Chinese‐style green modernization. This paper uses exploratory spatial data analysis, the spatial panel Durbin model, and the panel threshold model. The results show that the spatial correlation between substantive green innovation and digital industry agglomeration is significantly positive. Digital industry agglomeration has a positive spatial spillover effect on substantive green innovation. Under the adjustment of two mechanisms, digital industry agglomeration, and government innovation preference, the optimistic impact of digital industry agglomeration on substantive green innovation shows a “gradient” growth.
