In the context of China’s new infrastructure construction developing rapidly, this paper explores the sustainable new infrastructure green development pattern. We establish qualitative and quantitative indicators for green technology innovation (GTI) at both the societal macro level and enterprise micro level, capturing the multidimensional nature of China’s green innovation dynamic. Additionally, we create an indicator system for China’s new infrastructure investment intensity (NTI) across three areas: information infrastructure, integration infrastructure, and innovation infra-structure. Using provincial panel data from 2010 to 2020, we construct a coupling coordination degree model (CCDM) to examine the level of coordination between NTI and GTI. Our findings reveal that: the degree of coordination between NTI and GTI follows a U-shaped curve, with both subsystems remaining far from highly coordinated during rapid development; the coupling level of NTI and GTI in China is currently at a near dissonance level overall; the degree of coupling and coordination between NTI and GTI is mainly influenced by policies, and the coupling level is higher on the enterprise side than on the societal side; the two parameters (α-NTI and β-GTI) widely used in prior studies have less of an effect on the coordinated coupling system than other factors considered herein.
