Abstract: This paper takes the per capita tourism economy of 14 cities (states) in Hunan Province from 2000 to 2018 as the research object, and uses the Dagum Gini coefficient and its decomposition method to measure the regional differences of tourism economy in Hunan Province, and then uses the convergence theory to test the province and the four major tourism. The convergence characteristics of the circle. The results show that: (1) The spatial differences in per capita tourism income of the province and the four major tourism circles are prominent. The interregional disparity is the main source of Hunan’s tourism economic disparity. The intraregional disparity and the hypervariable density show a slow downward trend. The tourism differences are mainly concentrated in the two major tourism circles of Western Hunan Province and Chang-Zhu-Tan. (2) The province and the four major tourism circles not only have σ convergence, but also all have conditional β convergence. At the same time, there is also absolute β convergence in the province and the three tourism circles around Dong-Ting Lake, West Hunan, and South Hunan. (3) Regional economic development level, tourism resource endowment, fixed asset investment, urbanization rate, transportation accessibility and information development level have a strong influence on the convergence of the tourism economy of the province and the four major tourism circles.
