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

Abstract

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