1. appropriately stimulate import demand and increase social supply. The central bank should, according to the changing trend of international payments and from the perspective of adjusting foreign exchange supply and demand in a timely manner, suggest that the state appropriately reduce tariffs, tilt and guide the provisions on credit and foreign exchange sales, so as to increase the supply of goods in short supply in China, reduce the pressure of foreign exchange on the central bank to adjust the money supply, reduce the stock of social money and balance social supply and demand. 2. Reasonably determine the level of foreign exchange reserves. At present, the continuous increase of foreign exchange reserves is an important reason for the increase of foreign exchange holdings in China. Therefore, a reasonable level of foreign exchange reserves should be determined to reduce the impact of foreign exchange holdings on the money supply. The level of foreign exchange reserves is a dynamic concept. Theoretically speaking, moderate foreign exchange reserves should be comprehensively considered in combination with the national macroeconomic situation, balance of payments structure, monetary policy and macro-control of foreign exchange policy. It is generally believed that foreign exchange reserves should keep paying for imported foreign exchange for three to four months and repaying about 10% of foreign exchange debts. Based on this understanding, China's total foreign exchange reserves are not insufficient at present. The central bank should further coordinate monetary policy and foreign exchange policy, adjust foreign exchange receipts and payments in current account, control the increase of foreign exchange reserves, make full use of macro-control means such as exchange rate lever, interest rate lever, foreign debt statistical monitoring system and balance of payments statistical reporting system, make a long-term analysis of the trends involving changes in national foreign exchange receipts and payments, and determine a reasonable level of foreign exchange reserves. At the same time, the central bank should strengthen the management of the state's foreign exchange reserves in accordance with the principles of safety, liquidity and appreciation, so as to avoid valuable foreign exchange resources being idle. 3. Gradually expand the scope and proportion of foreign exchange holding enterprises. Under the current circumstances, although it is not feasible to completely replace compulsory settlement with voluntary settlement, the scope and proportion of foreign exchange holding enterprises can be gradually expanded and remitted to the people, thus making the foreign exchange distribution structure that is excessively inclined to the central bank gradually reasonable. Furthermore, as a policy suggestion, we can consider the retention ratio of foreign exchange as a special monetary policy control tool, and control the total foreign exchange reserves by adjusting the proportion of foreign exchange in enterprises and banks, so as to control the proportion of foreign exchange and achieve the effect of regulating the money supply. When the rapid growth of foreign exchange accounts for an increase in the pressure of money supply, the proportion of private foreign exchange accounts for an increase. On the contrary, when it is necessary to increase the money supply through foreign exchange, the proportion of private foreign exchange can be reduced. Through this improvement, it will help to develop the adjustment of foreign exchange holdings into a monetary policy tool to stabilize economic fluctuations. 4. Strengthen the central bank's ability to regulate the foreign exchange market. The ultimate goal of monetary policy is to stabilize the value of local currency and promote economic development. In the case of a large amount of foreign exchange, the central bank should innovate foreign exchange hedging tools on the basis of issuing central bank bills, and pay attention to cooperating with other tools. In addition, it is necessary to change the pattern that the central bank has become the main buyer of the foreign exchange market, allow more financial institutions and foreign-funded enterprises to participate in the foreign exchange market, and make the foreign exchange market have extensive participation and efficient operation mechanism.
