Abstract: The construction of a park city is a brand-new practice of Chinese government in the implementation of the new development concept in urban development. At present, the research on park city construction based on the perspective of the public as the main body is relatively weak. In this study, Chengdu city, which is the first park city construction demonstration site in China, was selected as the case area, and the survey data （N=957） was obtained by using the structured participation evaluation questionnaire, which was analyzed by the classical logistics regression model. The results showed that: Firstly, factors such as age, occupation, and air quality perception would affect the public's willingness to participate in the construction of park cities; Secondly, the influence of public participation behavior was analyzed as follows: factors such as age and access channels were related to the behavior of passively understanding relevant information; Factors such as academic qualifications were related to the behavior of actively understanding relevant information; the degree of transportation convenience and air quality perception were related to the behavior of giving suggestions to relevant departments; Connectivity and environmental awareness were related to the behavior of on-site investigation. All the above research results have certain reference significance for the construction of park cities.
