Abstract:  Based on the panel data from the year of 2013 to 2018 of 30 provinces (autonomous regions, and municipalities) in China, the Moran index and spatial econometric model are introduced to analyze spatial agglomeration and economic growth effect caused by the development of fintech. The results show that the development of fintech in China shows spatial correlation, and it has a positive effect on economic growth, that is, the every 1% increase in the level of fintech development will make the level of economic development increase by 0.196%. The tertiary industry is the main way for fintech to promote economic growth. Finally, suggestions are made on the relationship between fintech development and economic growth.

Key words: fintech, economic growth, spatial correlation, spatial econometric model
