摘要
本文基于BCC-DEA模型和DEA-Malmquist指数方法,利用2000-2011年中国30个地区的投入产出面板数据,对物流行业能源效率现状及变动原因进行分析。研究表明:我国物流行业整体能源效率水平不高,呈现从东部向中西部递减的趋势;技术进步是推动我国物流行业能源效率提高的主要因素;在一些年份和地区,纯技术效率负增长减缓甚至阻碍了物流行业能源效率的提高。因此,应对不同地区制定不同节能政策,将中西部作为我国物流行业节能的重点地区;发挥技术进步对能源效率的显著提升作用,进一步加速技术进步;将纯技术效率的提高当作物流行业能源效率提升的突破口。
With input and output panel data of 30 domestic regions from 2000 to 2011 , this paper analyzes the present situation and reasons of change of energy efficiency of logistics industry through BCC -DEA model and DEA-Malmquist index.The studies show that, the energy efficiency of domestic logistics industry is at a low level , and decreases from east to west; technological progress is main factor to promote energy efficiency of China ′s logistics industry; in some years and regions , decreasing of pure technical efficiency slows down or even hinders the progressing of energy efficien -cy.According to these conclusions , we should develop distinct energy conservation policy for different regions , make the middle and west China as the key areas; give full play to technological progress on the role of enhancing energy efficien -cy, further accelerate technological progress; make pure technical efficiency as a breakthrough for the development of energy efficiency of logistics industry .
