Impact of Urban Government Attention on Urban Green Technology Diversification

Abstract Urban green technology diversification (GTD) has become a crucial driver of urban long-term economic growth and sustainable development. However, research on the impact of urban government attention to green innovation (UGAGI) on urban GTD remains limited. This paper addresses this gap by using panel data from 2011 to 2021. Through text analysis and regression models, we identify a significant inverted U-shaped relationship between UGAGI and urban GTD, indicating an optimal level of government attention for fostering technological diversification. Findings reveal substantial technological and regional variations in this effect: UGAGI’s incentive impact is stronger for related GTD than unrelated GTD, with regional heterogeneity observed as well—UGAGI in the eastern region promotes unrelated GTD, while in central and western regions, it favors related GTD. Additionally, the relationship between UGAGI and GTD strengthens as internet development advances, emphasizing the role of digital infrastructure in amplifying policy impacts. These insights not only highlight the potential drawbacks of excessive government attention but also suggest strategic adjustments for more effective urban green technology policies. This study contributes to understanding the nuanced impacts of government attention on environmental governance, offering recommendations for urban policymakers seeking to enhance sustainable green technology growth through tailored, regionally informed approaches.
