摘要
基于物流业的能源强度现状,从数学层面对能源路径依赖做理论分析,提出最优能源强度理论,分析物流业能源强度受影响的因素并据此建立计量模型,运用广义最小二乘和广义矩估计进行实证分析。研究发现:1能源价格能显著起到抑制物流业能源强度的作用,进出口贸易、货物周转量、内贸、邮政业务水平的增长对物流业能源强度均有显著正影响;2物流业从业人数的上升会降低物流业能源强度,有利于物流业发展;3从各地区来看,东中西部地区物流业能源强度呈现递增趋势;4物流业能源强度滞后影响在统计上无明显意义。此外,针对物流业在能源利用效率、提升集约化经营水平、货运设备通用化等方面提出建议,这有利于物流业节能降耗,降低能源强度。
From the current situation of energy intensity in logistics industry,the energy path dependence is analyzed,and the optimal energy intensity theory is also put forward for the logistics industry from the mathematical level.Then,the factors affecting the energy intensity of logistics industry are analyzed,and the measurement model is established,and the empirical analysis is carried out by using the FGLS and GMM.The main conclusions includes：1Energy prices can significantly inhibit the energy intensity,import and export trade,goods turnover,domestic trade,the growth of the postal service level have significant positive impacts on energy intensity of logistics industry.2The increase in the labor of logistics industry will also reduce the energy intensity of the logistics industry,which indicates that that the labor of the logistics industry is in favor of the development of the logistics industry.3From various regions,the energy intensity of the logistics industry in the eastern and western regions is characterized by an increase.4The lagging effect of energy intensity in logistics industry has not obvious significance in statistics.In the end,some suggestions are put forward in terms of energy utilization efficiency,improving intensive collaborative operation,and freight transport equipment generalization,which can be beneficial to energy saving and consumption reducing and reduce energy intensity.
