Reason;
(A) the long-term foreign trade surplus is an important reason for the formation of huge foreign exchange reserves.
(2) Preferential foreign investment and foreign trade policies have brought a lot of foreign direct investment, resulting in a continuous surplus of revenue and expenditure capital on the same day.
(3) The inflexible remittance and application system has caused great pressure for RMB appreciation and increased China's foreign exchange reserves.
(D) The global economic imbalance has prompted a large amount of US dollar reserve funds to return. Under the condition of a country's open economy, the internal imbalance of the economic system needs corresponding external imbalance to make up. The increase of China's foreign exchange reserves and the continuous surplus of foreign trade have become the external manifestations of alleviating internal imbalances.
The positive impact is to enhance solvency and international status ... (in fact, it is the function of foreign exchange reserves)
Negative effects:
First, it increases the operating cost of the central bank outside hedging, and weakens the independence of the central bank's monetary policy and the effectiveness of monetary policy regulation.
This "hedging" operation aimed at weakening the negative impact of a large number of base currencies has limited effect.
Second, the dynamic structure that leads to economic growth is unbalanced, which is not conducive to the transformation of economic growth into domestic demand-oriented mode.
Third, it has increased the pressure of RMB appreciation, which is not conducive to the smooth development of foreign trade.
Fifth, it has become an important reason for excess liquidity, which has affected the efficiency of bank's capital use and aggravated the imbalance of economic structure.
