Heterogeneous Effects of Green Finance on Urban Decarbonization: Evidence from 285 Cities in China
arXiv:2606.06986v1 Announce Type: new Abstract: While green finance has become a key instrument for low-carbon city transitions, its actual decarbonization effects and transmission mechanisms remain unclear. This study employs econometric models and machine learning-based analysis to examine whether and how green finance reduces city-level carbon intensity. Results show that green finance significantly lowers carbon intensity, with green bonds and green investment having the strongest impacts and evident spatial spillovers. The effects vary by development level, being most pronounced in Fourth
This study from 2026 provides empirical evidence on a critical policy instrument (green finance) for decarbonization, at a time when climate action and economic transitions are escalating.
It demonstrates green finance's tangible impact on carbon intensity, validating financial mechanisms as a key lever for environmental policy and urban development in major economies.
The understanding of green finance's effectiveness is strengthened, potentially accelerating adoption and refinement of related policies in other regions facing similar decarbonization challenges.

Increased investment in green bonds and sustainable infrastructure projects across other developing and developed nations.
Enhanced global collaboration on green finance frameworks and regulatory standards, driven by proven efficacy.
The acceleration of a global 'green race' where countries compete to attract green capital and develop low-carbon economies, potentially reshaping international economic power dynamics.
