本文认为．虽然目前中国投资率较高而投资效率较低．但投资效率与投资率存在此消彼长的关系；短期内继续以较高投资率拉动经济增长仍是可行的策略；若各省投资率基本一致，则投资效率差异就是地区增长差距拉大的决定性因素；从内部投资效率比较而言，真正过热的省份主要是胶东半岛、长江三角洲和珠江三角洲的几个经济强省。因此加大对中西部的政策倾斜对这些省份几乎没有负面影响。

This article points out that there is negative correlation between investment rate and investment efficiency. Then it evaluates the inner investment efficiency by the congestion model of DEA. The results of theoretical and empirical analysis show that：（1） It is an available strategy to apply high investment rate to pushing economic growth in short term. （2） The differ- ence of investment efficiencies is the determination factor to enlarge the gap among provinces. （3） Only a few provinces in the east coast own extra investment and there is nearly no bad influence to them if the central government gives more help to the West or Middle provinces.
