Study on the impact of selective two-child policy on sex ratio at birth
【Abstract】If the family planning policy can lead to the increase of sex ratio at birth, then the fertility policy adjustment such as the selective two-child policy is bound to ease the momentum of the increase of sex ratio at birth. To test this assumption, this study employs the latest data on the sex ratio at birth from all the provinces to investigate the effects of the selective two-child policy on the sex ratio at birth. This paper concludes that the selective two-child policy will ease the sex ratio at birth of the first child but worsen the sex ratio at birth of the second child. Because for a couple having son preference the selective two-child policy actually means another chance to have a son, which will worsen the sex ratio at birth of the second child. Therefore, the key for easing the sex ratio at birth is to change fertility culture of son preference.
