Methods From December 2018 to May 2019, the information and data and WTP of the staffs in enterprise and institution in Tianjin were collected through questionnaire survey and conditional value inquiry method by simple random sampling, and analyzed the influencing factors by Cox regression model. Results A total of 221 staffs were surveyed, with an average age of （32.9±0.6） years,and more males（56.1%）. The median WTP was 350（P₂₅=300,P₇₅=400） yuan.The staffs who were master degree or above（HR=0.261,95%CI： 0.079-0.861）, personal payment（HR=0.365, 95%CI： 0.151-0.946）, very satisfied（HR=6.07e^-17, 95%CI： 5.14e^-18-7.17e^-16）and generally satisfied（HR=0.219, 95%CI： 0.057-0.845）with the previous post-examination services were less likely to be unwilling to pay; the staffs who generally familiar with（HR=2.949, 95%CI： 1.249-6.964） and don’t familiar with（HR=2.416, 95%CI： 1.068-5.745） the services and have generally sense（HR=3.410, 95%CI： 1.392-8.357） and weak sense（HR=18.168, 95%CI： 3.911-84.408） of belonging to work were more likely to be unwilling to pay（P<0.05）.
