1. The premise of the deposit reserve system is that it can effectively adjust the base money supply by adjusting the deposit reserve ratio. In foreign countries, because financial innovation is very active, it is impossible to effectively control the base money supply by adjusting the deposit reserve ratio, but at the present stage of underdeveloped financial innovation in China, the base money supply can be well controlled.

2. Foreign enterprises mainly carry out direct financing through the securities market, and the indirect financing mode of bank loans accounts for a small proportion. When a large part of the total social financing is not realized through deposit-taking financial institutions, the role of adjusting the deposit reserve ratio can only be limited to loans issued by deposit-taking financial institutions, and the scope is greatly reduced, so the policy effect is greatly reduced. But at the present stage in China, indirect financing accounts for a large proportion. Therefore, controlling the bank's money supply through the deposit reserve ratio can effectively control the credit scale.

Central banks in many countries, such as the United States, Canada, Switzerland, New Zealand, Australia and so on. , have reduced or cancelled the statutory reserve ratio, zero reserve ratio is becoming a trend.

Take the United States as an example. According to the reserve ratio standard of deposit-taking financial institutions set by the Federal Reserve of 20 1 1 year, trading accounts are divided into three grades, and the reserve ratio of the following part of 10700 USD (including 10700 USD) is 10700 USD (including 580 USD). For non-personal time deposits, the reserve ratio is 0;

For Eurodollar loans, the reserve ratio is 0. The above data show that the statutory deposit reserve ratio abroad is much lower than that at home. More importantly, the deposit reserve ratio is rarely used as a monetary policy tool in western countries.
