Factors Influencing the Energy Efficiency of Tourism Transport in China

中国旅游交通的能源效率及其影响因素（英文）

Transport is a major component of energy consumption and 002 emissions in travelling. Understanding changes in the energy efficiency of tourism transport （EETT） and factors affecting this is important to the promotion of low-carbon tourism. This paper established a new method following the top to bottom principle and analyzed EETT variation characteristics and influencing factors from 1994 to 2013 in China. We found that the energy consumption of tourism transport （ECTT） increased from 178.21 PJ in 1994 to 565.82 PJ in 2013 at an average annual growth rate of 6.27%; CO2 emissions of tourism transport （CETT） went up from 14.96×10^6t to 47.94×10^6 t due to person-trip and trip distance growth. EETT went from 3.22×10^6 person-trips PJ^-1 in 1994 to 5.99×10^6 person-trips PJ^-1 in 2013 at an average annual growth rate of 4.90%, and the CO2 emissions of tourism transport unit person-trips （CETTU） shifted from 26.07 kg person-trips^-1 in 1994 to 14.01 kg person-trips^-1 in 2013. Energy intensity decline, scale effects and policy promotion were key factors that enhanced EETT. Meanwhile, trip mode changes and enjoyment-oriented transport hindered EETT. Based on our analysis, we suggest methods to decrease ECTT and CETT. and enhance EETT.

交通是旅游过程中能源消耗和碳排放的主要环节,认识旅游交通能源效率变化及其影响因素对推动旅游低碳化发展具有重要意义。基于中国旅游交通及相关数据,在测算不同类型旅游交通工具能源消耗系数的基础上,遵循"自上而下"原则构建新的研究方法,分析考察1994-2013年旅游交通的能源消耗、碳排放、能源效率及其影响因素。结果显示,1)中国旅游交通能源消耗由178.21PJ增长至565.82PJ,年均增长率为6.27%,相应的CO_2排放由14.96×10~6 t增长至47.94×10~6 t,主要由旅游出游人次数快速增长和旅游出行距离增加引起;2)中国旅游交通能源服务效率由3.22×10~6人次PJ^(-1)提高至5.99×10~6人次PJ^(-1),能源生态效率由26.07 kg人次^(-1)提升至14.01 kg人次^(-1);3)单位交通能耗降低、规模效应、政策推动等成为能源效率提高的主导推动因素,但旅游出行方式变化、享受型交通工具的发展等阻碍了能源效率的提升。基于分析结果,提出了中国旅游交通降低能源消耗、提高能源效率的建议措施。
