The contingent valuation method (CVM) was used along with a questionnaire survey and field research methods to analyze the factors affecting willingness to pay (WTP) for urban parks in Tai’an. The results indicated that roughly 50% of the residents visited the urban parks weekly. Doing physical exercises and viewing topped the list of activities. Residents of different characteristics had different WTPs for the service functions of urban parks. From the two surveys, 60.1% and 61.4% of residents would be willing to pay. The average individual WTPs were 42.2 yuan·a-1 and 43.1 yuan·a-1 in the two surveys, and the medianin dividual WTP was 20.0 yuan·a-1. WTP was mainly affected by satisfaction, and WTP value was mainly affected by education level and income. Other factors had some correlation, but none were significant. Finally, some useful suggestions and references were given to the government in order to enhance the urban park services proposal.
