摘要
交通运输、仓储和邮政业对国民经济的健康发展起着重要作用。采用2005—2009年全国30个省(自治区、直辖市)的面板数据,运用DEA-Malmquist方法实证分析中国及各省份交通运输、仓储和邮政业的全要素生产率,并将其进一步分解为纯技术效率、技术进步率和规模报酬变动。分析结果表明,中国交通运输、仓储和邮政业的发展状况不佳,年均TFP增长率为-2.4%,其中纯技术效率增长率为-4.7%。
Studies have shown that, transportation, storage and the postal service play an important role in the healthy development of the national economy. Panel data of 30 provinces during 2005 to 2009 are used, and the Malmquist productivity index is applied to measure the TFP growth rate of transportation, storage and the postal service which was lately divided into technical efficiency index, technological progress index and returns to scale change index. The results show that: China's transportation, storage and the postal service develop in poor condition, and the technical efficiency growth rate must be improved.
