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.

Research on the coupling mechanism and influencing factors of digital economy and green technology innovation in Chinese urban agglomerations

“…The Pearl River Delta urban agglomeration had the highest coupling coordination level, followed by the Yangtze River Delta urban agglomeration and the Beijing-Tianjin-Hebei urban agglomeration, both in a mild disordered state. These findings are consistent with Zhang and Yin 8 , Zhang et al 30 , the digital economy is underdeveloped and lacks the capacity to efficiently integrate its digital components into the green technology innovation system. There is still scope for enhancing the coordinated advancement of the digital economy and innovative green technology.…”

“…The coupling model of digital economy and green technology innovation constructed in this paper calculates the development and coupling degree of digital economy and green technology innovation in China from 2011 to 2020, and promotes the coordinated development of digital economy and green technology innovation based on the coupling model. The calculation results are basically consistent with the literature 6 , 30 , 40 , 50 . The calculation results show that the overall degree of coupled and coordinated development of digital economy and green technology innovation in China maintains a continuous improvement, but the spatial difference is significant.…”

“…Some researchers utilise the Dubin model, coupling coordination degree model, and exploratory spatial analysis method to examine the impact of digital economic industry segmentation on green technology innovation. They also measure the degree of coupling coordination development and spatial effect between the two 30 .…”

Study on the Coupling Coordination Development between the Digital Economy and Innovation Efficiency: Evidence from the Urban Agglomeration in the Middle Reaches of the Yangtze River

“…Li and Feng examined the coupled coordination relation between innovation and DE development in the four strategic regions of China [18]. A great number of research methods have been utilized in the study of coupling and coordination relations, including methods such as kernel density estimation, Markov chain, and Dagum Gini coefficient decomposition [18,19].…”
