Abstract:With the development of China's urbanization, the influx of rural labor force into cities has become an inevitable trend of development. China has also become the country with the largest number of population flow and the largest scale in the world, which has brought a significant impact on the development of Chinese society. . In this context, it is of great significance for us to study the transfer of rural labor force, the increase of farmers' income, and the optimization of income structure to solve the problems of unbalanced and insufficient development currently faced by China. Through empirical analysis with the data of rural labor transfer, it is concluded that rural labor transfer has a positive effect on the increase of farmers' income.
