中国旅游业碳生产率时空分异格局研究

Study on spatial and temporal differentiation pattern of carbon productivity

提高旅游业碳生产率是实现旅游业碳减排和旅游经济增速的重要举措,有利于进一步推动旅游可持续发展。运用“自下而上”法测算旅游业碳排放量,利用平减指数转为以1995年为基期的不变价计算我国旅游业碳生产率,继而采用自然断点法分析旅游碳生产率的时空分异特征。研究表明:①研究期内我国旅游业碳生产率发展以2012年为“分水岭”,2012年以后我国旅游业碳生产率呈稳定增长态势;②我国旅游业高碳生产率整体呈“东高西低”“低效率区减少、高效率区增加”的空间分布格局;③旅游业碳生产率发展不平衡,各省区差异明显。

Improving tourism carbon productivity is an important measure to realize tourism carbon emission reduction and tourism economic growth,which is conducive to further promoting the sustainable development of tourism.The“bottom-up”method is used to cal culate tourism carbon emissions,and the deflator is converted to a constant price based on 1995 to calculate China’s tourism carbon produc tivity.Then the“natural breakpoint method”is used to analyze the temporal and spatial differentiation characteristics of tourism carbon pro ductivity.The results show that:①during the study period,the development of China’s tourism carbon productivity took 2012 as the“water shed”,and after 2012,China’s tourism carbon productivity showed a steady growth trend;②the overall high-carbon productivity of China’s tourism industry presents a spatial distribution pattern of“high in the east and low in the west”“low-efficiency areas decrease and highefficiency areas increase”;③the development of tourism carbon productivity is unbalanced,with obvious differences among provinces and regions.
