The net investment in the market means that the amount of funds put in by the central bank using various monetary policy tools is greater than the amount of funds returned, and the amount here reaches 296 billion.

The investment here is mainly a monetary policy tool for open market operation, that is, the central bank uses cash to buy central bank bills or government bonds existing in the market, so that funds can go to the market and bonds and central bank bills can go to the central bank. Once the central bank needs to quit, it can sell bonds or central bank bills. Of course, there are other monetary policy workers.

The same, but its action path is not the same.
