ABSTRACT In the past years, China’s fertility rate has experienced negative growth. In order to cope with the decline in fertility rate and the ageing of the population, the multi-child policy was implemented in 2015, that is, from the original husband and wife having only one child to having two or more children. Since the promulgation and implementation of China’s policy will have a greater impact on people’s livelihood, so before and after the implementation of the fertility policy, the impact of residents ’ political connectivity on fertility desire needs further study. This study categorizes residents’ political connectivity into political participation behaviour, political background, and political attitudes to explore the impact on residents’ fertility intentions. It conducts an empirical analysis of residents’ fertility intentions using data from the China General Social Survey (CGSS). The study found that before and after the implementation of the multi-child policy, there was a positive correlation between political participation behaviour and fertility intention, and there was no significant change. The influence of residents with party members ‘political background and residents’ political attitude on fertility intention has changed greatly, from negative correlation to positive correlation.
