数字经济与旅游业碳排放:空间格局及溢出效应

Digital Economy and Carbon Emission of Tourism Industry:the Spatial Pattern and Spillover Effect

在数字中国建设下,探究数字经济与旅游业碳排放的空间格局及空间溢出效应,有助于推动旅游产业“数字化”与“低碳化”协同发展。基于2011—2020年中国省级面板数据,运用综合评价指数、自下而上法、空间自相关、空间错位模型和空间杜宾模型深入剖析数字经济与旅游业碳排放的空间格局及其空间溢出效应。结果表明:在空间分布上,中国数字经济与旅游业碳排放均呈现出“东部高,西北和西南部低”的空间布局,地区非均衡性显著;在空间集聚上,数字经济与旅游业碳排放均具有明显的空间正相关性,表现出以长三角地区为主的HH集聚以及以中西部地区为主的LL集聚特征;在空间错位上,中国绝大多数地区数字经济与旅游业碳排放之间存在较为严重的正向空间错位现象,广东省空间错位指数均值绝对值最高,呈现负向高错位特点;湖北省均值绝对值最低,空间错位演变较为复杂;在空间溢出效应上,数字经济发展对本地区旅游业碳排放具有显著抑制作用,而对邻近地区旅游业碳排放具有显著促进作用。

In building a digital China,exploring the spatial pattern and spatial spillover effects of carbon emissions from the digital economy and tourism industry can help promote the coordinated development of“digitalization”and“lowcarbon”in the tourism industry.Based on China′s provincial panel data from 2011 to 2020,this study uses comprehensive evaluation index,bottom-up method,spatial autocorrelation,spatial dislocation model,and spatial Durbin model to deeply analyze the spatial pattern and spillover effects of carbon emissions from the digital economy and tourism industry.The results are as follows.In terms of spatial distribution,the carbon emissions of China′s digital economy and tourism industry both exhibit a spatial layout of“high in the east,low in the northwest and southwest”,with significant regional imbalance.In terms of spatial agglomeration,there is a significant positive correlation between the digital economy and carbon emissions from the tourism industry,exhibiting HH agglomeration mainly in the Yangtze River Delta region and LL agglomeration mainly in the central and western regions.In terms of spatial mismatch,there is a serious positive spatial mismatch between the digital economy and tourism carbon emissions in the vast majority of regions in China.Guangdong province has the highest absolute value of the mean spatial mismatch index,showing a negative high mismatch characteristic;The absolute value of the mean in Hubei province is the lowest,and the spatial dislocation evolution is relatively complex.In terms of spatial spillover effects,the development of the digital economy has a significant inhibitory effect on the carbon emissions of the local tourism industry,while it has a significant promoting effect on the carbon emissions of nearby tourism industries.
