摘　　要：综合包括地区生产总值等指标在内的多项指标作为衡量基础设施投资产出效果的指标,更能全面地反映基础设施投资的绩效。通过应用非参数的DEA方法,计算我国1999～2006年的基础设施投资的Malmquist生产率指数,克服了参数方法只能用一个指标衡量基础设施投资绩效的不足,并对基础设施投资的效率变动进行分析。研究结果表明,我国基础设施投资对经济拉动的作用正逐渐变小,同时由过去注重通过加大基础设施投入促进沿海地区的经济发展,正逐步向关注中西部地区的基础设施投入对经济发展促进作用的转移;同时,我国基础设施投资规模效率,正逐年有所改善,各地区的基础设施配置的纯技术效率变化不大,表明我国的基础设施投资仍可按照目前的投资规模稳步进行;而改变目前生产率逐年衰退的关键是推进基础设施投资的技术创新,推进基础设施投资与配置的生产技术前沿。Gross regional product,per capita gross regional product and urbanization level were regarded as indicators measuring the output of infrastructure investments,fully reflecting the performance of infrastructure investments.The Malmquist productivity index of infrastructure investments,for analysis and evaluation of infrastructure investment efficiency,was calculated through the application of DEA non-parameters approach,without the deficiency of using an indicator to measure infrastructure investment performance.The results showed that the pulling effect of infrastructure investments for economic development was being reduced gradually and the focus has shifted from infrastructure investments of promoting economic development in the eastern areas to those promoting economic development of the middle and western regions,that the scale efficiency of infrastructure investments was gradually improved,that the pure technical efficiency change was leveling off,which showed that the current scale of infrastructure investments was modest,and that the key of getting rid of declining productivity was to promote technology innovation of infrastructure investment and allocation.
