能源约束下我国全要素生产率的测算——基于DEA-Malmquist指数的分析

Estimates of Total Factor Productivity under Energy Constraint ——Based on DEA-Malmquist Index Analysis

采用非参数的DEA-Malmquist指数法,对能源约束和知识资本作用下的我国经济总量的全要素生产率进行了研究。结果表明:以往的研究只是将物质资本存量和人力资本作为投入要素,夸大了我国全要素生产率的增长率;1987—2009年我国全要素生产率的平均增长率为负值,技术效率对全要素生产率的增长没有影响,全要素生产率的提高完全来自于科技进步的贡献。

The paper uses the non-parametric DEA--Malmquist index method, and estimates China^s e-conomic aggregate TFP under the action of intellectual capital and energy constraints. Research shows that pre-vious studies merely took physical capital stock and human capital as input factors, and that resulted in exag-gerating China＇s total factor productivity growth. China＇s total factor productivitys average growth is nega-tive between 1987 and 2009; the technical efficiency of total factor productivity growth is not affected. Totalfactor productivity growth entirely comes from the contribution of scientific and technological progress.
