The results of panel threshold regression.

China has been fully implementing the policy of the cultural and tourism industrial integration since 2018. However, the value-added benefits of this policy are not prominent, and the relationship between industrial integration and the value added to the tourism value chain was seldom addressed by researchers. In the context of China’s high-quality development, it is necessary to conduct the impact of the integration of cultural and tourism industries on the value added to tourism value chain. This paper proposed four theoretical hypotheses and the corresponding econometric models based on the panel data from 2013 to 2020 in China’s Jiangsu Province. According to empirical results, the integration of cultural and tourism industries is spatially unbalanced, with notable imbalances between the south and the north. This paper identified a new connection between cultural and tourism integration and the tourism value chain. It is found that the integration of cultural and tourism industries can enhance the value added to tourism value chain either directly or indirectly through the information technology, with the direct effect being positively moderated by tourism agglomeration. Moreover, this paper may overturn how people generally think about the integration between cultural and tourism industries. It reveals a single-threshold effect that only when the integration of cultural and tourism industries reached a high level will it exert a positive effect. To be more specific, not all Chinese cities are suitable for implementing cultural and tourism integration, because the integration is likely to be ineffective in regions where the cultural industry is substantially less developed than the tourism industry.

自2018年起，中国全面推行文化和旅游产业融合发展政策。然而，该政策的增值效益尚未凸显，且学界鲜有研究探讨产业融合与旅游价值链增值之间的关联。在中国高质量发展的时代背景下，探究文化旅游产业融合对旅游价值链增值的影响具有重要现实意义。本文基于中国江苏省2013至2020年的面板数据，提出四项理论假说及对应的计量模型。实证结果显示，文化旅游产业融合存在空间非均衡性，南北区域差异显著。本文揭示了文化旅游融合与旅游价值链之间的全新关联：文化旅游产业融合可通过直接路径或借助信息技术的间接路径提升旅游价值链增值，且直接效应受旅游集聚的正向调节。此外，本文或颠覆人们对文化旅游产业融合的普遍认知：其存在单一门槛效应，仅当融合水平达到较高层级时方能发挥正向作用。具体而言，并非所有中国城市都适合推进文化旅游产业融合，若某一地区文化产业发展水平显著落后于旅游业，则该融合策略大概率难以奏效。
