数字化基础设施建设与旅游经济增长——基于中介效应与调节效应的机制检验

Digital Infrastructure Construction and Tourism Economic Growth:Mechanism Analysis Based on Mediating Effect and Moderating Effect

在系统揭示数字化基础设施建设对旅游经济增长作用机理的基础上,基于2011—2019年的省级面板数据,构建数字化基础设施建设水平评价指标,运用面板固定效应模型、中介效应模型和调节效应模型进行实证检验。研究发现:数字化基础设施建设显著促进旅游经济增长,内生性与稳健性检验均支持这一结论。进一步研究发现:数字化基础设施建设对国内旅游经济增长影响更大。分地区异质性检验显示:在东部地区、在长江经济带,数字化基础设施建设对旅游经济增长的促进作用更为明显。机制检验表明:数字化基础设施建设具有地区带动效应,主要通过经济发展、技术创新发挥部分中介作用;数字化基础设施建设还具有产业驱动效应,能够正向影响旅游产业效率以及旅游产业结构对旅游经济增长的作用效果。

This paper systematically reveals the mechanism of digital infrastructure construction on tourism economic growth,then constructs the evaluation index system of digital infrastructure construction,and conducts empirical tests by using the panel fixed effect model,mediating effect model and moderating effect model from 2011 to 2019.The empirical results show that digital infrastructure construction significantly promotes the tourism economic growth,and the endogenous test and robustness test support this conclusion.Further research finds that digital infrastructure construction has a greater impact on domestic tourism economic growth.Regional heterogeneity research found that digital infrastructure construction plays a more significant role in promoting tourism economic growth in the eastern region and the Yangtze River Economic Belt.Mechanism tests show that digital infrastructure construction can promote regional development and increase tourism economic growth through economic development and technological innovation;Meanwhile,the digital infrastructure construction can promote the development of tourism industry,and play a positive regulation role on the growth of tourism economy through the improvement of the tourism industry efficiency and the upgrading of tourism industrial structure.
