The Analysis Of Impact On Transportation Energy Consumption By Transportation Structure

Transportation is an important part of modern economy and a basic industry for the sustainable development of the country.Transportation is the industry of terminal energy consumption,has become one of the fastest-growing sectors of energy consumption in China,is an important field to achieve the goal of energy saving.The adjustment of transportation structure is an effective way to achieve the goal of energy saving.Therefore,it is significant to analysis the impact on transportation energy consumption by transportation structure.Based on the influence factors of transportation energy consumption,this paper analyses the impact on transportation energy consumption by transportation structure.(1)Through the review of transportation structure and energy consumption,research content and framework are instituted.The related theories and research methods of transportation structure and transportation energy consumption are summarized,which provides a theoretical basis for the analyse of the impact of transportation structure on energy consumption.(2)Analysis the impact of transportation structure on energy consumption.The influence factors of transportation energy consumption are divided into quantitative impact,structural impact and energy intensity impact.The development of transportation is divided into the the same level of isostructuralism period?the different level of isostructuralism period?the same level of isomerism period and the different level of isomerism period.(3)The functional relationship model between the growth rate of quantitative impact and the growth rate of energy consumption are established in the same level of isostructuralism period and the different level of isostructuralism period,to analyse the impact of transportation turnover on energy consumption.The functional relationship model between the growth rate of structural impact and the growth rate of energy consumption are established in the same level of isomerism period and the different level of isomerism period.According to the image of the model established in the isomerism period,the impact of transportation structure on the energy consumption be analyzed.(4)Ampirical analysis has been made with the impact on transportation energy consumption by transportation structure from 1985 to 2014.The empirical results show that there is a clear functional relationship between the growth rate of structural impact and the growth rate of energy consumption.In the same level period of isomerism,the relationship between the growth rate structural impact and the growth rate of energy consumption is quadratic function;in the different level of isomerism period,the relationship is cubic function.According to the fitting image,the energy consumption intensity of comprehensive transportation in China is volatility increasing,the growth rate of transportation energy consumption will gradually increase with the increase of the growth rate of structural impact when the growth rate is greater than zero.
