Abstract: In the era of “three children”， how to promote the transformation of fertility policy from focusing on the single link of “birth” to improving the systematization of “fertility” has become an important issue to be solved urgently in response to the crisis of low fertility rate in China. Based on the dual perspective of policy tools and fertility friendliness， this study analyzes provincial birth-support policies in China from 2016 to 2020. The results show that the current birth-support policy has some difficulties in the use of policy tools， such as lacking demand-type tools， placing too much emphasis on “fertility” but less on “parenting” and “education”， and failing to fully reflect the concept of fertility friendliness in the design of policy tool system. It is necessary to strengthen the supply of demand-oriented policy tools， improve the supporting policies of “birth-child-rearing”， pay attention to the coordination of policies， enhance the whole-process， inclusive and forward-looking birth-support policies， and build a friendly birth-support policy system.

Key words: birth-support; policy tool; fertility friendliness
