Sports tourism plays a significant role in the revitalization of rural areas in China.This study analyzedsurvey responses from 406 rural residents and conducted surveys with 15 village leaders in the Dabie mountainregion.The results showed that 85.71%of the rural residents believe that their family’s average income increasedby about 19865.93 yuan because of the presence of sports tourism in the area.They also showed that the sportstourists engaged in 17 kinds of consumption activities within the local villages.Additionally,it seems that 86.39%ofrural residents see potential benefits from sports tourism,and 85.71%of the residents’household incomes wereincreased due to sports tourism.In that regard,the average household annual income increased by 4677.58 yuan,and the average annual income of the residents in the whole area increased by 449000 yuan.Despite the positiveimpact of sports tourism in generating income for rural residents and contributing to rural revitalization,the tourismindustry faces challenges.These include a lack of sufficient market appeal,leading to a new“Matthew effect,”disparities in income distribution that conflict with the goals of rural revitalization,and a deviation from the intendeddevelopmental direction.Considering these findings,it is recommended to establish a sports tourism structure thataligns with local characteristics,incorporate sports tourism projects into the Chinese government's public serviceinitiatives,safeguard rural incomes amidst sports tourism development,and strengthen the connection betweensports tourism and rural revitalization. 展开更多
