本文选取2008-2018年长江经济带11省市的面板数据，运用GML指数测算各省市旅游绿色全要素生产率（GTFP），并构建旅游技术创新、产业升级与绿色全要素生产率的PVAR模型，探讨旅游技术创新、产业升级与绿色全要素生产率之间的动态关系。结果表明：长江经济带11省市旅游绿色全要素生产率存在明显的时空异质性；旅游技术创新与旅游产业升级之间以及与旅游绿色全要素生产率之间存在正向的相互作用，而旅游产业升级与旅游绿色全要素生产率的作用关系存在一定的反向互动关系；旅游产业升级对旅游绿色全要素生产率与旅游技术创新有相对程度较大的影响。因此，在综合考虑地区关联性与差异性下，加强旅游技术创新、产业升级与绿色全要素生产力的相互联动，有利于实现长江经济带旅游业“技术—产业—绿色经济”均衡发展。

Based on the panel data of 11 provinces and cities of the Yangtze River Economic Belt from 2008 to 2018,the article uses the index of GML to measure tourism green total factor productivity (GTFP),and constructs a PVAR mode to analyze the dynamic?relationship among tourism technology innovation,industrial upgrading and GTFP. The results show that the tourism GTFP of 11 provinces and cities in the Yangtze River Economic Belt shows a significant spatial and temporal heterogeneity;the interaction impact between tourism technological innovation and tourism industry upgrading as well as with tourism GTFP are positive,while there is a certain inverse interaction between tourism industry upgrading and tourism GTFP;tourism industry upgrading has a relatively large impact on tourism GTFP and tourism technology innovation.Therefore,under the consideration of regional correlation and difference, strengthening the correlation between tourism technological innovation and tourism industrial upgrading, promoting regional tourism technology innovation level,speeding up the transfer process of accepting industries in the eastern and central regions,will be beneficial to realize the balanced development of "technology-Industrial-green economy" of tourism in the Yangtze River Economic Belt.
