The Impact of New Urbanization on Quantity Increase and Quality Improvement of Green Innovation: Based on Multivariate Moderating Effect Models

New urbanization is a major national strategy that China has proposed and implemented. Whether new urbanization (NEU) can promote quantity increase and quality improvement of green innovation (GI) is a common concern of the government and scholars. This paper empirically analyzes quantity increase and quality improvement effects of new urbanization on urban GI by adopting the panel data of each city from 2011 to 2022. The study finds that new urbanization not only has a positive contribution to the quantity increase of GI in cities but also plays a positive role in the quality improvement of GI. Digital inclusive finance will further amplify the dividends of new urbanization and exert the GI effect. The interaction of digital inclusive finance and government support, informatization, regional economic development, and energy consumption also amplify the dividends of NEU and exert strong “quantity increase” and “quality improvement” effects on GI. The stronger the government’s green support, the more conducive it is to new urbanization to further exert quantity increase and quality improvement effects on GI. The conclusions of this paper have important policy implications for further promoting the construction of new urbanization and GI.
