摘要
本文以投入产出分析思路与IPCC的CO2折算方法为基础,对湖北省17个城市的区域旅游能源消费与CO2排放进行了估算,并利用SBM-Undesirable模型对区域旅游低碳效率及其全要素生产率作出了测度与分析。研究结论显示:湖北省旅游业能源消费量从2007年的2 008 518吨上升到2011年的5 121 460吨,对应CO2排放总量从2007年的6 340 302吨上升到2011年的15 773 041吨;住宿、餐饮、景区游览、购物、娱乐、邮电通信及其他服务等二级部门间接能源消费量(间接CO2排放量)远高于直接能源消费量(直接CO2排放量),而交通部门直接能源消费量(直接CO2排放量)远高于间接能源消费量(间接CO2排放量)。效率评估显示,若不考虑非期望产出,则旅游业发展效率存在被低估的可能;湖北省旅游业低碳效率整体上处于较低水平,不同区域旅游业的低碳效率水平存在较大差异,区域旅游经济系统内部生产要素使用潜力尚待发掘;在分析期内,湖北省区域旅游业低碳效率整体上处于上升状态,规模性因素所推动的技术进步是区域低碳旅游经济发展效率攀升的关键动力,而纯技术效率变化则不利于生产率提升。
Through input-output analysis and IPCC carbon dioxide calculation, we assessed the energy consumption and COz emissions of tourism sectors in 17 cities of Hubei Province in 2007 - 2011. Then we used the SBM-Undesirable model to measure and analyze the development efficiency of low-carbon tourism economy and its total factor productivity in the cities. The results show that the total energy consumption from urban tourism in Hubei soared from 2 008 518 tons to 5 121 460 tons from 2007 to 2011, and the related CO2 emissions soared from 6 340 302 tons to 15 773 041 tons from 2007 to 2011. Among the secondary sectors, the accommodation, food, site visits, shopping, entertainment, posts ＆ telecommunications and other services segments contributed much more indirect energy consumption （indirect CO2 emissions） than direct energy consumption （direct emissions）, while the transport division producted less indirect emissions than direct emissions. Results of efficiency measurement indicate that it could underestimate tourism development efficiency without considering undesirable output. The overall efficiency of economic growth through low-carbon tourism in Hubei is at a rather low level and varies significantly among cities, and there are untapped potentials with internal productive factors in the economic system of urban tourism. From the perspective of dynamic shift, however, the overall efficiency within the analyzed period was in an upward trend, driven primarily by the technological progress induced by the scale factor, whereas the purely technological efficiency changes undermined the growth of productivity.
