The results show that, for large Banks, there is a significant negative correlation be-
tween regional Fintech development level and banks’ risk-taking. However, the regression
coefficient of small banks did not pass the robustness test, and there was no significant
correlation between them. This shows that the phenomenon that the development of
Fintech inhibits the risk-taking of banks exists in large-scale banks, but not in small-scale
banks. In other words, the development of Fintech will have a greater impact on small and
medium-sized banks, which verifies the research hypothesis 1.
7.1.3. Heterogeneity Analysis Based on the Banking System
The research samples in this article are urban commercial banks and rural commercial
banks. Although urban commercial banks and rural commercial banks are all belong to
regional banks, there are obvious differences between them. Generally speaking, urban
commercial banks are transformed from urban credit cooperatives, mostly distributed in
urban areas, and controlled by the local government where they are registered. The rural
commercial banks are mostly converted from rural credit cooperatives, and they are mostly
distributed in rural areas, subject to the restrictions of the provincial federations where they
are registered. Normally, compared with rural commercial banks, urban commercial Banks
have larger asset scale, wider business scope, more concentrated customer groups, and
better development prospects, but they also bear greater competitive pressure. Therefore,
considering the difference between the two, the samples studied in this paper are naturally
divided into urban commercial banks and rural commercial banks according to their nature.
Since the individual effect of the bank has been determined, we use the time-fixed effect
model for heterogeneity analysis (the results are shown in Table
12
).
