Abstract: There have long been debates and conflicting arguments in the studies of population carrying
capacity． This paper examines dilemmas and challenges in the studies of population carrying capacity．There are three major difficulties in the research of population carrying capacity: difficulty in conducting quantitative models of population carrying capacity with empirical researches due to limitations in theoretical hypotheses，difficulty in accurately determining the results of population carrying capacity due to the changing nature and the complexity and uncertainty of the influencing factors of population carrying capacity，and difficulty in operationalizing policy measures deriving from the research on population carrying capacity．The author argues that population carrying capacity exists objectively，and scholars should not abandon their research just because of the difficulties and problems in the studies of population carrying capacity．There is a need in the research on population carrying capacity to disembarrass of that of biological carrying capacity．Studies on population carrying capacity need to be conducted in dynamic perspectives．
