Abstract: Based on the cross-sectional data of China's eight ethnic provinces and autonomous regions with large ethnic minority populations in 2020,an evaluation index system of human resources deve-lopment is constructed from the five aspects of population size,economic development,education and training,medical and health,and cultural environment,giving an empirical study on the development level of rural human resources in these provinces and municipals.Through data standardization processing and factor analysis,the load matrix is established,and the single factor evaluation scores of human resources quality,cost,environment and development and the comprehensive evaluation scores are calculated.The results show that the order of the comprehensive level of rural human resources deve-lopment in the eight ethnic provinces and autonomous regions is Inner Mongolia,Guangxi,Qinghai,Xinjiang,Ningxia,Guizhou,Yunnan and Tibet,from high to low.In order to improve the overall deve-lopment level of rural human resources,considering the evaluation results of individual factors in different provinces and municipals,Inner Mongolia should focus on the environmental factors of human resources development and promote the quality development of human resources;Guangxi should give full play to the quantitative advantages of human resources and transform them into quality advantages;Qinghai should speed up the construction of a modern ecological economic system in characteristic rural areas and simultaneously improve the health level of the whole people.Under the premise of speeding up development,Xinjiang should focus on upgrading technological innovation to improve the rural industrial structure;Ningxia should focus on education and training and vigorously enhance the level of governance;Guizhou should speed up high-tech economy and empower the development of rural human resources;Yunnan should further promote private economy and border economy and raise the disposable income level of rural residents;and Tibet should do a good job in the basic work of human resources development and increase investment in education,medical care and infrastructure construction.
