1. foreign exchange retention: foreign exchange retention refers to the amount of foreign exchange income obtained by an enterprise and the net foreign exchange income after distribution and use in accordance with the state regulations on foreign exchange management, and has applied to financial institutions for foreign exchange retention in accordance with regulations. The foreign exchange retention of export commodities is an important economic measure for the state to encourage exports, increase foreign exchange income, support local production and construction, and develop foreign trade.

2. Reasons for foreign exchange retention:

1. From the normative content of establishing foreign currency business under the new system, it should include the management content of foreign exchange cash and foreign exchange quota;

The state implements the foreign exchange retention system, encourages enterprises to earn more foreign exchange and settle more foreign exchange, and gives enterprises certain foreign exchange control rights;

13. Tourism is a foreign exchange earning industry, and all enterprises are involved in foreign exchange business, so the system should make corresponding provisions in this respect. At the same time, the banking system stipulates that most of the foreign exchange adjustment income retained by enterprises is used for production development, and a small part is used for welfare and incentives. The new system will adjust foreign exchange income to current profits and losses.

3. Calculation method:

Foreign exchange earned by trade and export is calculated in full according to export income. The full amount of export proceeds refers to the balance after the exporter deducts the transportation insurance premium, commission, indemnity and bank charges paid by the exporter for export, returns the floating foreign exchange principal used for producing export products, and returns the principal and interest directly used for producing products with the export proceeds of products approved for increasing production. According to the internal unified conversion rate table of various currencies against the US dollar, the foreign exchange for trade export will be fully converted into US dollars, and then the US dollar amount will be multiplied by the retention ratio of the central, local and foreign exchange income units stipulated by the state. The product income is the foreign exchange quota retained by the central, local and foreign exchange earning units respectively, and the retention currency is US dollars.

For the calculation of retention, the unit that approved the retention only has income and does not need to spend foreign exchange, and the retention is calculated in full according to the income; Units with income and expenditure shall be retained according to the net foreign exchange income of income minus expenditure. The income of all units, except those specially approved, shall be sold to banks, which shall record the foreign exchange earning performance and keep it once every quarter according to the foreign exchange earning performance; If the net foreign exchange income cannot be settled quarterly, the retention time can also be calculated according to different situations. The foreign exchange income of civil aviation, transportation, railways, posts and telecommunications, customs and insurance is concentrated in the head office of China Bank to calculate the retention.
