摘要
货运能耗的系统测度和节能潜力分析,对制定有效的节能策略至关重要。本文从生命周期视角出发,构建货运能耗系统测度和节能潜力分析框架,量化供给侧和需求侧各因素对货运能耗的影响,从而识别关键因素。鉴于不同区域资源禀赋及货运供需特征差异,将该框架应用于义乌-宁波集装箱货运通道。结果表明:忽视生命周期和运输链次要活动,特别是前者,会显著低估货运能耗,导致各节能策略真实贡献评估有偏;综合能耗的公路运输直接能耗弹性为0.67,远高于供给侧和需求侧其他能耗影响因素,是中短期货运节能的重中之重;现有条件下"公转铁"策略单独实施的节能效果欠佳,建议中短期搭配直接能耗节能策略,而中长期宜搭配间接能耗节能策略。
Systematic energy consumption measurement and energy-saving potential analysis of freight transportation are crucial to formulating energy-efficient strategies.An analysis framework for energy consumption measurement and energy-saving potential of freight transportation is constructed from life cycle perspective to quantify the impact of various supply-side and demand-side factors and to identify the key influencing factors.Given that the differences in resource endowments and supply-demand characteristics in different regions,this framework is applied to the YiwuNingbo container freight corridor.The results show that:ignoring life cycle and secondary activities of transportation chain,especially the former,would underestimate the energy consumption,which would lead to inaccurate evaluation of the contribution of each energy-saving strategy;the direct energy consumption of road transportation for embodied energy consumption elasticity is 0.67,which is much higher than that of other influencing factors of the supply-side and demand-side,and it should be given the top priority for freight transportation energy-saving in the short-/mediumterm;under the current conditions,the energy-saving effect of road-to-rail strategy is limited if without other strategies,and the energy-saving strategies for direct energy consumption are recommended in the short-/medium-term,and the energy-saving strategies for indirect energy consumption are recommended in the medium-/long-term.
