Study on the Coupled and Coordinated Development and Evolution of Digital Economy and Green Technology Innovation

Green technology innovation offers a new dynamic support and realization path for the comprehensive transformation upgrading of digital economy intensive development mode. The study green technology’s coupled coordinated evolution with is conducive to promoting quality efficiency economy. With aid coupling coordination degree, nuclear density, Gini coefficient, this paper develops evaluation index system based on theoretical mechanism empirically investigates spatial temporal in Chinese regions from 2011 2021. results show that there an imbalance regional innovation, overall strength needs be improved; empirical density gap further revealed, driving optimized; coefficient are obvious differences contribution rates between regions, collaboration improved. Finally, it suggested that, future, capabilities should comprehensively promoted, drive mechanisms optimized, inter-regional regulatory improved, at higher level realized as soon possible.
