中国星级饭店碳排放时空演化特征及影响因素研究

A STUDY ON THE TEMPORAL AND SPATIAL EVOLUTION CHARACTERISTICS OF CARBON DIOXIDE EMISSIONS AMONG STAR-RATED HOTELS IN CHINA AND THE INFLUENCING FACTORS OF THE EVOLUTION

基于2000~2016年中国各省区星级饭店碳排放量的测算结果,采用泰尔指数、ArcGIS技术分析了中国星级饭店碳排放时空演化特征,并利用面板数据估计模型揭示星级饭店碳排放时空演化的影响因素。研究表明:(1)中国星级饭店碳排放在时序上呈先递增后波动递减的态势。(2)中国星级饭店碳排放的区域差异呈缩小趋势,各区域内部差异是造成全国总体星级饭店碳排放差异的主要原因。(3)中国星级饭店碳排放东多西少的梯度分布格局较为突出,随时间推移各省区碳排放量出现不同程度的减少。(4)中国星级饭店碳排放时空分布格局受星级饭店碳排放强度、星级饭店规模、星级饭店结构和气候条件的综合影响。

Based on the calculation results of carbon dioxide emissions from 2000 to 2016 among star-rated hotels in all provinces of China,through applying Theil Index as well as ArcGis technology,this study analyzes the temporal and spatial evolution characteristics of the emissions and reveals the influencing factors of such evolution by taking full advantage of the Panel Data Estimating Model.The study finds that:(1)Chronologically,the carbon dioxide emissions of star-rated hotels in China have seen a steady increase at first and then a progressive but fluctuating decrease.(2)The spatial differences of carbon dioxide emissions among star-rated hotels of different provinces in China present a decreasing trend,and the inner differences within each province are the main causes that result in the overall differences.(3)It is quite obvious that the distribution of carbon dioxide emissions of China s star-rated hotels takes a look of gradient distribution pattern with more emissions in the east and less in the west.As time goes by,the emissions of each province decline by various degrees.(4)The temporal and spatial distribution pattern of the carbon dioxide emissions among star-rated hotels in China are influenced comprehensively by a combination of the carbon emission intensity,the scales,and the structures of the star-rated hotels as well as the climate.
