| 摘 要： | 增量资本产出比（ICOR）是评价一个国家或经济体制宏观投资效益的常用指标。本文从宏观投资效益内涵、经济增长来源和时滞性等三个角度分析了ICOR指标的缺陷，并进行了实证分析，指出ICOR作为宏观投资效益的衡量指标具有较大的局限性，但根据ICOR值的变化情况分析投资对经济增长作用的长期变化趋势是有效的。

| Abstract: | Incremental capital-output ratio is a common indicator for evaluating investment efficiency at macro-economic level of a country or economic system.This article analyzes defects of the indicator of ICOR from three points including the connotation of investment efficiency,source of economic growth and time lag,and does empirical analysis.We find that ICOR has the constraint for evaluating investment efficiency at macro-economic level,but ICOR is an effective indicator for analyzing long-term trend of change in the role that investment plays in economic development. |

| Keywords: | investment efficiency at macro-economic level incremental capital-output ratio constraint |
