In order to compare the coverage degree of incentive mechanism of maternal care in Jiangsu and Guangdong, and to verify the feasibility of comprehensive quantitative evaluation of incentives, this study collected all policy documents related to women's health from the open channel system, the coverage degree of incentive mechanism were extracted and comprehensively quantified. Spearman correlation, linear regression, etc. were used to analyze the relationship between the coverage degree of incentive mechanism and maternal mortality. The results showed that the coverage degree of incentive mechanism between the two places has increased steadily from 2000 to 2017, with Jiangsu Province rising from 34.6% to 70.47%, and Guangdong Province rising from 23.79% to 64.75%, which is highly negatively correlated with maternal mortality (Jiangsu r = -0.834, Guangdong r = -0.915). The coverage degree of incentive mechanism in Jiangsu and Guangdong has been increasing year by year, and basic coverage has been achieved, but there is still room for improvement. The effective incentive mechanism for business authorities and primary medical institutions should be further improved.
