Abstract: In the process of population ageing in China,rural population has an increasingly higher proportion of elderly than the cities,it has been widely cited as one of the characteristics of population ageing in China.This paper compared China with other countries and reveals that the phenomenon of higher elderly proportion in rural population than the urban is universal in the world.The research finding shows that the urban-rural inversion of population ageing will not last for a long time.With the socioeconomic development,large-scale rural-urban migration and urbanization will approach to the end;the proportion of the urban elderly will eventually exceed that in the rural.During this process,the transition of urban-rural difference of population ageing will experience four phases.In the first phase,the rural population ageing is higher than the urban;the difference between urban-rural population ageing will be enlarged increasingly.The second phase is that the rural population ageing is higher than urban,but the gap will be narrowed.The third phase is that the urban population ageing will exceed the rural area,the proportion of the urban elderly will be higher than the rural.At the last phase,the difference will be narrowed and diminished in the end.The transition model of the urban-rural difference of population ageing implies that the challenges of urban population ageing will exceed rural aging in the near future.Nevertheless,China should give more priority to issues of rural ageing in the first half of this century.
