摘要
为研究物流业能源效率对碳排放的影响状况,寻找有效降低物流业碳排放的途径,通过对2005—2015年我国30个省区市物流业能源效率进行分析,构建物流能源效率对碳排放影响双门槛模型,探悉物流业能源效率在不同区域经济条件下对物流碳排放的影响。结果发现,我国物流业能源效率总体水平较低,物流业碳排放总量增长态势显著,物流业能源效率对物流业碳排放具有显著门槛效应,对碳排放的影响随着区域经济发展水平的提高而显著增强。此外,产业结构、外商投资、教育水平与物流碳排放正相关;物流业专业化程度、城镇化与碳排放负相关。
In order to study the influence status of logistics energy efficiency on carbon emission and seek the approaches of effectively reducing carbon emission in logistics industry, through analyzing the logistics energy efficiency in more than 30 provinces in China from 2005 to 2015, a double-threshold model for the influence of logistics energy efficiency on carbon emission is established, discussing the influence of efficiency on carbon emission under different regional economy. The study result shows the overall level of China＇s logistics energy efficiency is low, the total carbon emission volume of logistics industry has an obvious increasing trend, logistics energy efficiency has a significant threshold effect on the carbon emissions, and the effect on carbon emission is obviously increased following the increase of regional economic development level. Moreover, industrial structure, foreign investment and education level are positively related to logistics carbon emissions, while the specialization degree of logistics industry and urbanization are negatively related to the carbon emissions.
