Measuring China's urban digital finance

With the full integration of digital information technology and financial services, digital finance has developed rapidly. As there are significant differences in the development level of FinTech and traditional financial sectors in different cities, it is important to evaluate the development level of urban digital finance. This study aimed to compile an index of urban digital finance to present an accurate and in-depth depiction of how urban digital finance has developed in China. Our sample covers 278 cities in China, over the period 2010–2020. This paper firstly constructs the urban digital financial index system from the three dimensions of digital financial services, digital financial technology, and digital financial operating environment, and then adopts a combination of subjective and objective methods to measure the urban digital financial index. This paper study revealed that China's urban digital finance has been on an upward trend from 2010 to 2020, and the digital finance operating environment is an important driving force for the growth of the urban digital finance index. The convergence of China's urban digital finance is decreasing, indicating that the gap in digital financial development between cities is increasing. Urban digital finance has positive spatial agglomeration, but this spatial agglomeration is decreasing.
