This study attempts to design a complete index to assess the green growth of regional economies from the point of view of the development of fintech. The index will be based on an in-depth examination of the effect mechanism that green finance has on green growth. Additional study reveals that innovations in fintech mostly foster green economic development by means of green lending and green investment. As a result, advancements in fintech have the potential to foster green productivity expansion by elevating the development degree of green finance. This is a field that has a great deal of reference importance for most nations. The development of financial technology has the opposite effect on the building of sustainable smart cities. This is mostly because both the development and commoditization of fintech need more resources, and these resources also come at a greater price. 2022 56 67 1366 https://creativecommons.org/licenses/by/4.0/ 10.54216/AJBOR.070205 https://www.americaspg.com/journal/1/article/1366 https://www.americaspg.com/storage/11761782601.pdf
