Based on the double decomposition method of population-weighted variation coefficient of the center-periphery model,this paper measures and decomposes the digital financial imbalance in 23 provincial-level regions of China from 2011 to 2019,reveals its spatial and structural sources,investigates the economic effects of digital financial imbalance and its decomposition items. It is found that: 1) During the sample period,the degree of digital financial imbalance shows a fluctuating downward trend in most provincial-level regions,but there is a certain rebound trend in recent years. 2) The digital financial imbalance between the central and peripheral regions is the main spatial source of the digital financial imbalance in each provincial-level regions,the digital financial coverage imbalance is its main structural source,the concentration effect is the main reason for the change of digital financial imbalance over the years. 3) The digital financial imbalance and its decomposition items have a nonlinear effect of promotion first and then inhibition on economic growth. This study enriches the discussion on the problem of uneven development,helps to clarify the degree,spatial source,structural source and economic effects of digital financial imbalance in various provincial-level regions,and provides reference ideas for further promoting the balanced development of provincial-level digital finance.
