中国交通运输能源效率及其影响因素分析--基于三阶段DEA和GWR方法

摘要

交通运输部门能源消耗占总能耗的比重虽然不高，但是对环境造成的影响较大。交通车辆数、人口密度、交通运营线路长度、旅客和货运量等都直接影响交通能源效率。采用三阶段数据包络模型分析各地区交通运输部门的能源效率，同时考虑到相邻地区交通运输状况的相互影响，构建空间地理加权回归模型对各个地区能源消耗的影响因素进行分析。研究结果表明：各个地区交通能源效率差异与地理区位有关，但是关系不大，主要与该地区的交通运输综合密切相关；提高交通领域能源效率的主要对策是合理进行交通运输状况的分布，调配交通运输车辆和根据不同的人口密度选择交通工具。%Energy consumption in transportation sector serious influence on the environment . The direct impacts on transport energy efficiency are :number of vehicle , population density , passenger , freight traffic etc .In this paper ,we use three‐stage model of data envelopment analysis of energy efficiency in the transport sector in China ,taking into account the interaction between adjacent areas the traffic and transport situation , build geographically weighted regression model . Research results show that the various areas related to energy efficiency and geographical location has little to do but mainly with integrated transport conditions in the area .A main counter measure to improve transport energy efficiency is a reasonable distribution of the traffic and transport situation ,the deployment of transport vehicles , choosing the way of transport upon the population density .
