In the context of global climate change problem intensifying due to a dramatic increase in carbon emissions, smart cities, as topical application digitalization and intelligence, have become new urban governance mode for countries, which helps achieve sustainable development. This research studies relationship between city construction (SCC) dioxide emissions based on differences-in-differences model (DID) propensity score matching (PSM) promote China dual goals high-quality The findings are follows: (a) SCC could emission reduction by reducing an average 11.4%, also has significant long-term dynamic effects.

With the rapid development of China’s economy, issue environmental pollution during urbanization has become increasingly prominent, posing a significant threat to residents’ health and quality life. While existing studies have explored economic impacts smart city initiatives their effects on carbon emissions, relationship between policies urban emissions remains underexplored. This study fills this gap by examining impact pilot pollutant using panel data from 280 Chinese cities (2007–2021) multi-period DID model. The findings demonstrate that construction effectively reduces level in cities, with effect persisting even after conducting various robustness tests. Furthermore, our mechanism analysis reveals upgrading industrial structure, enhancing green innovation capabilities, improving energy efficiency are crucial means which mitigates emissions. Additionally, we identify enhancement digital infrastructure reinforcement regulations can enhance mitigation efficacy development. suppressive is more pronounced non-resource-based cities.

In the context of global climate change, green development has become main goal smart city construction. Most existing research suggests that cities will enhance level total factor productivity (GTFP) in cities. However, this study found reduce production short term and increase it long term. Based on this, article selects three batches China from 2013 to 2019, uses Malmquist index model, common frontier function, panel data method analyze GTFP model early stage construction China. The that: (1) was less than 1 showed a downward trend, indicating (2) Technical efficiency is reason for decline rise medium Specifically, there U-shaped relationship between technological their GTFP. For every 1% technical later stages cities, increases by 47.3%. (3) process shows trend decreasing increasing middle stages. greater fluctuating upward improve city’s run. view we should attach importance ecological protection take effective measures carbon emissions during period. During period, policies such as taxation can be implemented encourage companies adopt cleaner technologies, strengthen exchange technologies accelerate flow knowledge, redundant information infrastructure, thus minimize This provides policy recommendations decision-making references further promoting new worldwide.
