按照宏观经济学的基本原理，经济要持续稳定发展，必须保持社会总供给与总需求的平衡。但一国经济起飞的准备阶段，通常难以平衡，出现“储蓄缺口”及“外贸缺口”，弥补这两个“缺口”的唯一办法是适当利用外资。进入９０年代以来，“两缺口”减少甚至转为盈余，外汇储备大幅度增加，利用外资规模已明显偏大，引进外资过度，造成外资代替内资，国内资本闲置，因而影响国内总量平衡，加大宏观调控难度及通货膨胀风险。 According to the basic principles of macroeconomics, the economy needs to maintain a steady and steady development and the balance between total social supply and total demand must be maintained. However, during the preparatory phase of a country’s economic take-off, it is usually difficult to balance the emergence of “savings gaps” and “foreign trade shortfalls.” The only way to make up for these two “gaps” is to make proper use of foreign investment. Since the 1990s, the “two shortfalls” have been reduced or even turned into surpluses. The foreign exchange reserves have risen sharply. The scale of the utilization of foreign investment has become significantly larger. The introduction of excessive foreign investment has caused foreign capital to replace domestic capital and idle domestic capital, thus affecting the balance of the domestic total.
