Abstract: Recently scholars have been calling for the loosening up of China’s one-child policy, and even the Chinese government has begun to show some willingness to do so. The call is not new. In my doctoral dissertation 25 years ago I first showed that China should allow couples to have two children and could still achieve the same population control goal as the one-child policy. I am glad to see that what I proposed 25 years ago is repeated by many scholars and even acceptable to the Chinese government.
