Study On Carbon Emission Efficiency Of Hotel On Wutai Mountain Scenic Spot

As ecological deterioration,climate change,global energy waste problems emerge in endlessly,carbon emissions is more and more aroused wide attention of scholars at home and abroad. In the recently concluded climate conference in Paris,the greenhouse gas emissions and the harm of high carbon energy use was stressed once again.It hope all the countries to jointly take measures to control climate change.As hotel was "big carbon emissions enterprise" of tourism,how to use scientific and effective measures to reduce the energy consumption and reduce greenhouse gas emissions,so as to improve the efficiency of energy efficiency and carbon emissions,is imminent.It needs to cause the attention of many scholars.So the study of the hotel efficiency and low carbon emissions path is of great significance.First,this paper takes the hotel buildings area, rooms and staff number as input indicators,and the main hotel consumption energy and resources,such as the annual water consumption,power consumption and coal consumption,as output indicators.Then it uses DEA model to calculate the carbon emissions efficiency of 28 hotels in2014.The results show that:(1)Pure technical efficiency and scale efficiency is relatively high,and pure technical efficiency level is slightly higher than the scale efficiency level;technical efficiency is low.(2)The number of the hotel in the stage of increasing return to scale,the scale of diminishing returns and constant return to scale were little changed.(3)In the contribution of decomposition efficiency to the overall efficiency,the pure technical efficiency’ influence to the technical efficiency is slightly bigger than the effect of the scale efficiency to technical efficiency.Second,two-way indicator species analysis and model combining correspondence analysis are used to study the influence of the seven important index to different kinds of hotel the three types of efficiency.Results show that:(1)It uses technical efficiency,pure technical efficiency and scale efficiency of 28 hotels to constitute a value of 28 x 3d data matrix,and uses two-way indicator species analysis to divide 28 hotels into four categories,hotels of the Ⅰ group belongs to the carbon efficiency completely hotel,the hotels of the Ⅱ group have high carbon efficiency,the Ⅲ group’s pure technical efficiency is the lowest,and the Ⅳ group’s scale efficiency is the lowest.(2)Then combined with the hotel water,electricity,coal consumption,registered capital,buildingarea,and the number of rooms and workers to constitute a index of 28 x 7 d data matrix.According to Canonical Correspondence Analysis,it can find that:as the diagonal of the second quadrant and the fourth quadrant,the type of hotel carbon efficiency transforms the pure technical efficiency with the lowest first Ⅲ group gradually to the hotel of the Ⅳ group hotel whose scale efficient is least,and transforms the high carbon emissions efficiency of the first Ⅱ group hotel to the complete carbon efficiency of the first Ⅰ group hotel.The hotel carbon efficiency increases gradually.(3)The influence index of the first group Ⅱ hotel is not obvious; The first seven hotels in Ⅲ group need to adjust coal consumption, water consumption,power consumption, and registered capital;The other 2 hotels and the hotels in Ⅳ group mainly need to adjust hotel rooms,staff number and construction area.Finally,It uses the method of mathematical statistics and questionnaire analysis to study other related influencing factors of the hotel carbon efficiency and carbon emissions.Results show that:(1)The relationship between the hotel’s carbon emissions efficiency and the carbon emissions is not obvious.The higher energy efficiency is not the same as low carbon emissions,but by improving the efficiency of carbon emissions is beneficial to reducing carbon emissions.(2)From the study about the problems existed in the process of hotel management of carbon emissions in the investigation,it can draw the following conclusion:firstly,the mostly hotels in scenic spot are aware of the importance of energy conservation and emissions reduction,but owing to the rise in the cost of enterprise capital limited,short-term and traffic influence etc.,only a few hotels taking effectively low carbon measures.Secondly,on some lower low carbon infrastructure,there is no big difference between different rating scale of the hotel.At present,the study of the carbon efficiency is lacking for the hotel, and the study of the carbon emissions efficiency in wutai mountain scenic area is blank,which is a great innovation of this article;Immature,but at the same time,due to previous studies is still flawed,this paper remains to be further improved in many respects.
