The Fifth Plenary Session of the 19th Central Committee of the Communist Party of China （CPC） stressed the importance of “solidly promoting common prosperity” in describing the vision of socialist modernization in 2035. In 2020，the per capita disposable income of rural residents in China will be 17，131.5 yuan，which is only 39% of the per capita disposable income of urban residents. And the total rural population is still 500 million，accounting for 36.1% of the total population. Further promoting the non-farm transfer of rural population and narrowing the income gap between urban and rural areas are sufficient necessary conditions for achieving common prosperity. The study designed two goals：one is assuming the urban-rural income gap of 1.8 by 2035. In 2035，the average arable land area of rural households will be 36.75 mu. China’s rural resident population will fall to 347.9 million，when the total population of the country will be 14.17 million，thus calculating the urbanization rate of 75.46 percent in 2035. Option II assumes that the income gap between urban and rural areas is 2，and that the average arable land area of rural households will be 35.7 mu in 2035. China’s rural resident population will fall to 358.04 million，with urbanization rate of 74.74 percent by 2035. According to international experience，China’s non-farm employment share still has room to rise，to expand the coverage of public services in urban clusters and central cities，to achieve urban and rural and inter-regional per capita income and quality of life is roughly the same，is the key to achieve common prosperity.
