Abstract:数字经济赋能旅游业智慧化转型,产业整体危机抵抗和创新转型能力得以提升,为黄河流域生态保护和高质量发展提供了新契机。在系统阐述数字经济影响旅游经济韧性的理论基础后,基于黄河流域81个地级市20082020年面板数据,运用固定效应模型、双重差分模型检验了数字经济对黄河流域旅游经济韧性的影响及其作用机制。结果表明:(1) 数字经济发展可以直接促进旅游经济韧性提升,以大数据综合试验区的设立作为准自然实验等一系列稳健性和内生性检验后结论依旧成立。(2) 数字经济通过促进要素流动、提高创新水平,间接提升了黄河流域旅游经济韧性。(3) 异质性分析表明,黄河流域数字经济对旅游经济韧性的作用受地理区位和旅游业发展程度的影响,其效应呈现为中游>上游>下游的状态;数字经济在旅游发展程度高的地区促进效果更好。研究结果为黄河流域深度推进数字+旅游的发展策略,加强旅游产业防范风险和应对外部冲击提供了政策依据。
