A Study On The Influence Of A New Type Of Pension Insurance For Rural Residents On Fertility Desire

In this paper,we use theoretical models and empirical tests to study on the influence of a new type of pension insurance for rural residents on fertility desire.In terms of theoretical models,this article uses the CRRA utility function of the relative risk aversion model to deduced from the theoretical level: the new rural insurance has a negative impact on the number of births and the fund will reduce the number of births.The adjustment will affect the family’s support for the elderly,which will cause certain changes in the number of births in peasant families.In terms of empirical research,this paper uses the five-year CGSS survey data to test the influence of a new type of pension insurance for rural residents on fertility desire from both qualitative and quantitative levels.The research results show that the new rural insurance can significantly reduce the willingness of residents to fertility desire,the new rural insurance have a sustained and stable income when people are old.Therefore,the willingness to bear children will continue to decline and the number of births will decrease.The new rural insurance under the sample of rural residents has a greater impact on the willingness to give birth to boys.In order to verify the accuracy of the above results,this paper uses the propensity value matching method and the instrumental variable 2SLS method to test the robustness of the above results.Rural endowment insurance will have a crowding-out effect on the number of births.This is roughly the same as the previous results,which further illustrates the robustness of the conclusions of this study.
