The present paper’s reliance on the same research team to develop the dual machine learning models and conduct the econometric analysis raises concerns about potential bias and the objectivity of the findings. This dual role may have influenced the methodological rigor and interpretation of results, potentially limiting the robustness of the study’s conclusions. Could the authors clarify what measures were taken to ensure the impartiality and validity of their analytical process, please?
Moreover, while the claims of “spatial spillover effects” and “enhanced innovation through green finance and financial technology” are conceptually compelling, the lack of detailed empirical evidence or clearly measurable outcomes leaves these assertions insufficiently supported. A more thorough explanation of how these mechanisms were quantified or validated would be highly beneficial to address this gap.
