江苏省作为横跨中国南北的交通枢纽之一,如何实现江苏地区铁路运行效率最优关乎江苏及其周边地区,乃至全国的经济发展。本文通过选取江苏铁路营业里程为投入指标,货运量、货物周转量、客运量以及旅客周转量为产出指标,采用数据包络分析法对2000-2013年江苏省铁路运行效率进行了计量。结果表明,除2005、2007、2008、2010年以外,其他年份江苏铁路均实现了技术有效。2000-2003年,江苏铁路运行规模效益呈递增趋势,2004年实现综合效率最优,而后近10年里规模收益一直递减。
As one of the transportation hubs that crosses the north and south of China, Jiangsu Province, how to achieve the optimal railway operation efficiency in Jiangsu Province, is related to the economic development of Jiangsu and its surrounding areas and even the whole country. This paper selects the mileage of Jiangsu railway as input index, freight volume, cargo turnover, passenger volume and passenger turnover as output indicators, and uses data envelopment analysis to measure the railway operation efficiency in Jiangsu Province from 2000 to 2013. The results show that except for 2005, 2007, 2008 and 2010, the other years of Jiangsu Railway have achieved technical and effective. From 2000 to 2003, the scale and efficiency of Jiangsu railway operation showed an increasing trend. In 2004, the overall efficiency was the best, and the scale returns of the past 10 years have been decreasing.
