Here we explored the willingness to pay for CAB-LA and associated factors, and price elasticity of demand (PED) of CAB-LA among men who have sex with men (MSM) in Guangxi, China.A cross-sectional study was conducted. Univariate and multivariate ordinal logistic regression were performed to explore associated factors of willingness to pay for CAB-LA. PED was used to measure the change in the number of participants willing to pay to a change in price.Results: A total of 1006 MSM were recruited, among which 84.1% was aged between 18-39 years old. The median (interquartile) of the maximum amount of willing to pay for CAB-LA was 200 (100-500) Chinese yuan (CNY) per month. Most (84.2%) were willing to pay less than 600 CNY per month. The number of participants willing to pay for CAB-LA significantly increased as the price decreased. When the price (CNY per month) dropped from 600 to 500, 500
