Abstract: The impact of rural public goods supply on urban-rural integration development was studied in order to optimize public goods supply policy and path. Using the global principal component analysis method, the urban-rural integration development level index from 2004 to 2020 was measured, and the effect of rural public goods supply such as education and medical care on the urban-rural integration development level was studied through the fixed effect model. The results indicated that the regional differences in the level of urban-rural integration development were obvious. The level of urban-rural integration development in the eastern region was higher than the national level, and the central and western regions were lower than the national average; the supply of rural public goods was positively correlated with the level of urban-rural integration, but the improvement rate of urban-rural integration in the central region was higher than that in the eastern region; the level of population urbanization and fiscal decentralization would promote the development of urban-rural integration, and the level of foreign investment would inhibit the development of urban-rural integration. It put forward suggestions on further strengthening the central and western rural public goods supply, improving the new urbanization related facilities and policies, and continuously increasing the financial investment in rural public goods supply.

Key words: rural public goods supply, urban and rural integration development level, global principal component analysis, fixed effect model
