物流业是高能耗及高排放行业,其节能减排需引起高度重视。将能源投入与污染物纳入全要素生产率分析框架,构建了基于投入导向与产出导向的DEA模型,测度了2006~2013年间中国29个省份物流业的节能减排效率和潜力,并对重点地区进行了评价。研究发现:中国物流业节能效率与减排效率都较低,年均分别为0.53与0.66。西部节能效率最低,中部减排效率最低,东部的节能效率与减排效率均最高。影响因素回归结果显示:研发强度、外商直接投资对物流业节能减排效率有正面影响,工业化程度、国有率则有负面影响。物流业节能减排效率与人均GDP呈现倒U型曲线,实现物流业增长与环境绩效改善的双赢发展极具挑战性。
Logistics industry is the main area of energy consumption and carbon emissions.By putting the non-consensual output into total factor production framework and based on the input and output-oriented DEA model,the efficiency and potential of energy-saving emissionreducing of logistics industry from 2006 to 2013is measured.The results reveal that logistics industry has lower efficiency on energy-saving potential and emission-reducing.The annual average efficiencies are 0.53 and 0.66 respectively.There is a downtrend in efficiency of emissionreducing.The west region has the lowest efficiency on energy-saving;the middle has the lowest efficiency on carbon emissions;and the northeast has the highest efficiencies both on energy consumption and carbon emissions.The affect factors regression results show that there is an inverted U-shaped curve relationship between efficiency and GDP per capita.RD intensity and FDI improve efficiency on energy-saving and emission-reducing,while industrialization and the ownership structure have negative effects on the efficiency.
