摘　　要： 基于国民收入总需求方程的理论研究表明,投资产出效率与消费-投资之比呈倒U型关系,其最优值取决于消费-投资之比与投资增长率的动态均衡。投资增长率是影响投资产出效率变动趋势的关键因素,而消费抑制减弱了投资驱动对经济增长的贡献。1992-2007年中国的省级面板数据研究表明,近五年84%的省区年度消费率低于最优的消费率水平,而且消费率有逐渐下降的趋势。因此,消费与投资的结构优化有助于投资产出效率的提升。 The study based on national income aggregate demand function indicates that the ratio between the investment-output efficiency and the consumption-investment rate has a relationship of inversed U shape, and its maximal value lies on the dynamic equilibrium of the consumption-investment rate and the investment growth rate. The investment growth rate is a key factor to affect the changing tendency of investment-output efficiency, while consumption restriction has weakened the contribution of investment to economic growth. The empirical analysis of the provincial panel data of 1992-2007 shows that in recent 5 years, 84% of the annual provincial consumption rate is lower than the optimal consumption rate, and consumption rate has a tendency of going down. Therefore, to optimize the consumption-investment rate will help to increase the investment-output efficiency accordingly.
