[Spatio-temporal Characteristics and Spillover Effects of the Synergistic Development of Digital Economy and Green Innovation under the Perspective of New Quality Productivity].
摘要
The formation of new quality productivity has provided new impetus for the synergistic development of the digital economy and green innovation. Based on the provincial panel data of China from 2012 to 2022， this study applied the coupling coordination model， Theil index decomposition method， and spatial Durbin model to explore the spatio-temporal evolution characteristics， regional differences， and spatial spillover effects of the synergistic development level of the digital economy and green innovation. The results showed that： ① In terms of chronological development， the synergistic degree of digital economy and green innovation showed a rugby ball-shaped distribution pattern. Most regions were still in the medium synergy stage. ② In terms of spatial pattern， the collaborative development level between the two showed a "high-low" two-tier distribution characteristic from east to west. The overall difference in the level of synergistic development between the two was a fluctuating downward trend， mainly stemming from the diversity and imbalance within the region. ③ In terms of influencing factors， new quality productivity had a significant positive spillover effect on the synergistic development of digital economy and green innovation and helped to improve the level of synergistic development in neighboring regions. Government support， economic development， industrial upgrading， and foreign investment were indispensable factors in this process. Therefore， it is recommended that each province should construct development programs according to local conditions and establish a linkage pattern for the synergistic development of the digital economy and green innovation， so as to provide decision-making references for the promotion of sustained， healthy， and efficient development of the economy.
