Evaluation Of Railway's Impact Efficiency On Regional Socio-economic System Based On DEA

Railway is one of the main means of transportation, plays an important role in the regional socio-economic development. In order to achieve the goal of building a moderately prosperous society and adapt to rapid economic development, railway's construction and operation is highly valued by administration. Due to various social structure, population and resource allocation, different regions of China have various demand of railway, and also railway's effect on the different regions have different extents. Therefore, to evaluate the railway's impact efficiency is conducive to the plan of the railway's network, construction and operation, thus contributing to regional social and economic development.First, the paper analyzes the factors of railway impact on the socio-economic based on the review of domestic and foreign research; second, according to the study of literature, we divide this complex socio-economic system into four subsystems: Society, Economy, Resource, Environment, and establish respectively the index evaluation system for each subsystem; finally, we use the DEAP software to complete the calculation of DEA model. This paper calculates separately the impact efficiency of the railway mileage, passenger capacity, freight capacity and railway's structure affect each subsystem. We use the subjective weighting method to empower weight to each subsystem, and then we calculate their weighted average efficiency, which is treated as the comprehensive efficiency. The main work obtained in this study is:(1) To explore the railway's impact efficiency on regional socio-economic. The paper establishes the index evaluation system and selects the Data Envelopment Analysis evaluation model, choosing the regions along Beijing-Shanghai railway, and then applies the index and method to the analysis of the practical problems.(2) To build an applicability index evaluation system. We use Literature Analysis, Reliability Analysis and Correlation Analysis to build the railway evaluation system of socio-economic impact indicators.(3) According to the empirical results, the main conclusions of this paper are:The technical efficiency values can be divided into three levels:The first level is Shanghai and Beijing; the second level is Jiangsu, Shandong and Tianjin; the third level is Hebei and Anhui. By the railway's impact efficiency on the regional socio-economic, the higher level of economic development and faster pace of development, the higher efficiency. In addition, railway's increment efficiency is higher than railway's stock efficiency.
