为量化分析我国铁路网运营的有效性,利用评价经济系统相对有效性的数据包络分析方法,就铁路网近年来运营的相对有效性进行了分析评价。从投入产出的角度,通过计算决策单元未充分利用的资源投入和产出指标输出不足的数量,分析决策单元非相对有效的原因,获得某些有关改善路网运营效率的管理信息;还就我国铁路网运营的有效性与国外主要国家铁路进行比较。结果表明,随着铁路网规模的扩大,路网质量的提高,尤其是近几年一系列运营组织措施的实施,不仅整个路网的运营有效性在提高,而且大多数铁路局(公司)所在路网的运营也是相对有效的;与国外主要国家相比,我国铁路网也是运营很有效的路网之一。
In order to quantitatively analyze the validity of railway network operation in our country, this paper analyzes and evaluates the relative validity of railway network operation in recent years by using data envelopment analysis method, which evaluates the relative effectiveness of economic system. From the perspective of input-output, through the calculation of the under-utilized resources input and output indicators of decision-making unit output less than the number of analysis of decision-making unit is not relatively effective to obtain some of the management information to improve the efficiency of road network operations; The effectiveness of railway network operation in China is compared with that of major foreign countries. The results show that with the expansion of the railway network and the improvement of the quality of the road network, especially the implementation of a series of operation and organization measures in recent years, not only the operational effectiveness of the entire road network is improving, but most of the railway administrations (companies) The operation of the road network is also relatively effective; compared with major foreign countries, China’s railway network is also one of the most effective road networks.
