transportation demand and supply meaning in English

运输供求关系

However , the results of these predictions are not very successful for the reason that the transportation quantity does not equal the demand . the actual transportation is the organic match of transportation demand and supply , as well as the partial equilibrium of the demand and supply under specific transportation situations that is not only the quantitative equilibrium but also the qualitative equilibrium
究其原因，在于运输量并不等同于需求量，它是运输需求与运输供给的有机统一，是特定运输环境下供给与需求的局部平衡，而这种平衡不仅仅是量上的平衡，更是质上的平衡。
This thesis starts from the introduction of the equilibrium of transportation demand and supply , assesses this kind of equilibrium by the criteria of " adaptability " , analyzes the premises of causing corresponding transportation under certain equilibrium , finally predicts the trend of equilibrium of demand and supply by the analysis of the changes of these preconditions for equilibrium and then calculate the increase of future demand
本文从道路运输供需平衡理论入手，以“适应度”来评价供需平衡状况，分析在一定平衡状态下形成相应运输量的条件，通过分析平衡条件的变化来估测未来运输供需的平衡趋势，并以此来推测运输需求的增量。
