【摘要】 当前道路运输能源消耗的统计方法已经不适合道路运输的现状,需要在目前道路运输企业管理机制下,通过建立能源消耗统计模型来实现由典型企业抽样推算一个省乃至整个国家的道路运输行业能源消耗量和消耗水平。基于这种想法,分别建立各省各类型车辆模型和对应类型车辆的全国模型,比较两者之间的误差,从而判断用多元线性回归方法实现由总体推算局部是否可行。经过研究验证,其推断误差较小,认为这种方法由总体推算局部可行。更多还原

【Abstract】 Currently the statistic method of roads transportation can not meet the needs of road transportation.Thus,a statistic model of energy consumption needs to be established to calculate energy consumptionand consumption level from typical corporation sample to the whole province or country. Based on this idea,vehicle models of all kinds in every province,and those in the whole country were established respectively.The errors of models were compared to judge whether it was feasible from the whole to part by multiple linear regression method.The result validates that the concluding error is less and that the method is feasible from whole to part.更多还原
