摘要
交通运输是国民经济的基础部门。未来随着国民经济的快速发展和人均收入水平的不断提高,交通运输部门的能源消费量将会以较高的速度增长,在决定我国终端能耗的局面中占据着非常重要的地位。本文应用集合模型方法建立了中国能源服务需求预测模型(Energy service demand projection model,ESDPM),在对未来经济和社会发展进行合理假设的基础上,预测了中国未来一直到2050年的客运和货运周转量以及小汽车保有量,并进行了国家和地区间的比较。结果显示,2005-2050年中国的客运和货运周转量将分别以年均增长率5.9%和5.1%的速度增长,2050年客运和货运周转量将分别达到23.1万亿人.km和74.7万亿t.km。小汽车将随着人均GDP的快速增加呈现出明显的"S"型增长关系,在小汽车拥有率饱和水平选取为0.4时,小汽车保有量将稳定在5.8亿辆左右。
Transportation is one of the main sectors of Chinag economy. With the rapid economic development and per capita income growth, the energy consumption of transportation is expected to grow at a higher rate and take a significant share in the total final energy consumption. The China energy service demand projection model (ESDPM) , is built based on the aggregate model methodology and employed to forecast China' s future passenger, freight transport and private cars, on the basis of reasonable assumptions of the future economic and social development. The model shows that China' s passenger and freight transport in 2050 will be 23.1 trillion p ~ km and 74.7 trillion t ~ km respectively, with the annual growth rate of 5.9% and 5.1% from 2005 to 2050,while private cars will increase in a ' S' -shaped curve with the rapid growth of GDP per capita. 580 million is the amount of stablization for cars with assumption of car ownership saturation rate of 0.4.
