摘要：Countercyclical fiscal regulation can mitigate economic risk, but this is bound to increase the scale of local government debt during an economic downturn, and then spread risk to the banking sector, forming potential financial instability factors. We extracted the three most important variables in this process: economic fluctuation, local debt risk and bank risk-taking to build an econometric model and found that: (1) both economic fluctuations and local government bond risks have a significant impact on bank risk-taking, which is negatively correlated with local economic growth, while the increase of local government bond risks tends to increase bank risk-taking in the long run; (2) the impact of local government debt risk significantly increases the loans of city commercial banks flowing into the construction industry. Therefore, the impact of local government bond risk on city commercial banks is concentrated in the impact on their construction loans. This study has an important reference value for timely and moderate countercyclical regulation, preventing local debt risk from spreading to banks, constructing a sustainable local government−bank ecology, and promoting sustainable economic development.
