从投入产出角度，运用超效率三阶段DEA模型与Malmquist模型相结合的分析方法，修正了环境因素与随机因素的影响，从静态与动态的时间角度对2008_2012年我国30个省（市、自治区）经济发展效率进行分析。结果表明：从静态层面看，我国各省经济发展效率不容乐观，综合效率值较低，大约2/3省的经济发展都处于低效状态；经济发展效率受环境影响较大，剔除环境因素的影响后，各省综合效率均显著下降；三大区域中，东部地区经济发展效率仍处于领先地位，西部地区次之，中部地区最低，但整体来看区域间经济发展效率差异逐渐减小。从动态层面看，通过Malmquist模型分析，考察期间全要素效率和综合技术效率M值逐年下降，技术进步效率逐渐增长，且全要素效率下降的主要原因是纯技术效率下降。因此，各地区应该充分发挥优势，加快技术创新，提高规模效率，进一步提升发展水平。%Viewing from the input and output of China's economic development,the economic develop-ment efficiency of 30 provinces in China during the period of 2008_2012 is analyzed by using the Malmquist Index model,while the impact of environment variables and random interference factors is revised. The result shows that,from static perspective,the development efficiency of the provinces under study is far from satis-factory. The comprehensive efficiency index is low. In about two thirds of the studied provinces,the economic development is of poor efficiency. The environment has great impact on the economic development efficiency. With the environmental factors being eliminated,the comprehensive efficiency of all provinces is in significant decline. Of the three geographical regions,the east takes the lead in development efficiency,followed by the western region and with the central being the lowest. In general,however,the regional gap in economic devel-opment efficiency is narrowing gradually. From dynamic perspective,through the analysis of Malmquist Index model,the total factor efficiency and the M value of comprehensive technology efficiency are decreasing year by year,whereas the technological progress efficiency is increasing annually. Since the decrease of total factor efficiency is caused mainly by the decrease of technology efficiency,the different regions should try to bring their strengths into full play,quicken the steps of technological innovation,increase scale efficiency and en-hance further the level of their economic development.
