摘　　要：基于2011-2021年我国49个重点旅游城市的面板数据,应用PVAR与耦合协调模型分析两者之间的响应关系、耦合协调度和时空演变特征.研究发现:重点旅游城市数字经济与旅游业碳排放效率均有不同程度提高,但具有空间发展不平衡的特点,且发展水平差距扩大,空间极化程度加剧.PVAR模型分析显示,旅游业碳排放效率是数字经济发展水平的格兰杰原因,旅游业碳排放效率可在一定程度预测后期数字经济发展水平.旅游城市数字经济与旅游业碳排放效率的耦合协调度逐年上升,但总体水平不高,且存在显著的地区异质性.耦合协调度呈现由东部、东北/中部向西部逐渐递减的“东高西低”特征.耦合协调度存在空间溢出效应,主要表现为“高-高”和“低-低”的空间正相关集聚效应.Based on the panel data of 49 key tourism cities from 2011 to 2021,PVAR and coupling coordination model were used to analyze the response relationship,coupling coordination degree and its spatio-temporal evolution.The results show that:both the development level of digital economy and the carbon emission efficiency of tourism industry in China s key tourism cities have improved with unbalanced spatial development level,widening gap and increasing spatial polarization degree.Carbon emission efficiency of tourism industry is characterized by significant self-reinforcing.PVAR model analysis shows that the carbon emission efficiency of tourism industry is the Granger s reason for the development level of digital economy,and the carbon emission efficiency of tourism can predict the development level of digital economy in the later period to a certain extent.The coupling coordination degree exhibits an“east-high,west-low”pattern,and gradually decreases from the east,northeast/central to the west.The coupling coordination degree has spatial spillover effect,which is mainly manifested as“high-high”and“low-low”spatial positive correlation aggregation effect.
