经常项目逆差是指一个国家在一定时期内，进出口贸易、跨国收入和转移支付等经常性项目上收入的总和小于支出的总和，即经常性项目出现了净支出。这种状况通常被认为是不利于经济发展的，因为这表明一个国家的外部竞争力不足，且需要从其他国家获取资金来支持国内经济。

经常项目逆差的原因有多种，包括国内消费和投资过高、货币贬值、国际贸易结构不合理等。在处理经常项目逆差时，国家通常会采取一系列措施，如降低利率、调整汇率、增加出口等，以改善国际收支状况。

英文：The current account deficit refers to a situation where a country has a total income less than its total expenditure in the current account, including import and export trade, cross-border income, and transfer payment. This situation is usually deemed to be detrimental to the economy, as it indicates that the country's external competitiveness is insufficient and it needs to obtain funds from other countries to support the domestic economy.

There are various reasons for the current account deficit, including high domestic consumption and investment, currency depreciation, and unreasonable international trade structure. In dealing with the current account deficit, the country usually takes a series of measures, such as reducing interest rates, adjusting exchange rates, increasing exports, etc., to improve the international balance of payments situation.
