Step 1: Understand the relationship between foreign exchange reserves and money supply.
When a country increases its foreign exchange reserves, it typically means that it has more foreign currency coming into the country, often as a result of a trade surplus or foreign investment.

Step 2: Analyze how an increase in foreign exchange reserves affects the money supply.
An increase in foreign exchange reserves can lead to an increase in the money supply if the central bank does not sterilize the inflow、When foreign currency comes into the country, it is typically exchanged for the local currency、This exchange increases the amount of local currency in circulation, thereby potentially increasing the money supply.

Step 3: Consider the effect of sterilization.
However, central banks can sterilize the impact of increased foreign exchange reserves on the money supply through various monetary operations、Sterilization involves selling government securities or other assets to absorb the excess liquidity that results from the exchange of foreign currency for local currency, thereby preventing an increase in the money supply.

Step 4: Determine the direct effect of increased foreign exchange reserves on money supply without sterilization.
Without sterilization, an increase in foreign exchange reserves tends to increase the money supply because more local currency is issued in exchange for the foreign currency.

Step 5: Address the statement directly.
The statement 增加外汇储备引起货币供应量减少 translates to An increase in foreign exchange reserves leads to a decrease in money supply、This is generally not true without specific actions by the central bank to sterilize the inflow.

Step 6: Conclusion based on typical economic understanding.
Typically, an increase in foreign exchange reserves is associated with an increase in money supply if not sterilized、Sterilization can prevent this increase, but the statement as given does not specify that sterilization occurs.

The final answer is: $\boxed{错误}$ (Incorrect)
