利用数字技术推动旅游供需有效对接、激发旅游消费潜力，成为畅通国内大循环的关键环节和重要引擎。文章融合多源数据构建2011—2019年中国285个地级及以上城市面板数据，基于数字技术创新与旅游供需耦合协调理论，运用双向固定效应模型、面板平缓转换回归模型与空间杜宾模型等方法，验证数字技术对旅游业供需耦合协调的多重影响效应。研究发现：①中国城市旅游业供需耦合协调水平整体上呈现持续增长状态，高低值的空间分布格局与旅游业发展的地理版图相似。②数字技术显著促进了旅游业供需耦合协调发展，而且这种影响效应在旅游业发展好、互联网水平高的地区更为突出。③数字技术对旅游业供需耦合协调水平提升具有非线性递增效应，并且随着市场化水平增高，影响效果和显著性随之增强。④空间杜宾模型检验发现，数字技术发展水平的提高不仅有助于促进本地区旅游业供需耦合协调，而且能够通过空间溢出效应推动邻近地区旅游业供需耦合协调水平提升。研究结论为合理推进旅游供需数据开放共享、打造满足多元化需求的数字文旅创新生态、实现中国城市旅游供需耦合协调水平整体提升提供有益参考。

This study integrates multi-source data to construct panel data of 285 prefecture-level and above cities in China from 2011 to 2019, based on the theory of digital technological innovation and tourism supply and demand coupling coordination, and utilizes the two-way fixed effect model, the panel smoothed transformation regression model and the spatial Durbin model to validate the multi-influence effect of digital technology on the tourism supply-demand coupling coordination. The main findings are as follows: 1) The level of coupling coordination of tourism supply-demand in Chinese cities shows continuous growth. 2) Digital technology significantly promotes the coupling coordinated development of tourism supply-demand, and this influence effect is more prominent in areas with good tourism development and high Internet level. 3) Digital technology has a non-linear incremental effect on the level of tourism supply and demand coupling coordination, and the effect and significance of the influence increases as the level of marketization increases. 4) The spatial Durbin model test found that the improvement of the level of digital technology development not only helps to promote coupling coordinated development of tourism supply and demand in the region, but also promotes the improvement of the level of tourism supply and demand coupling coordination in the neighboring regions through the spatial spillover effect.
