Healthy cities continuously attempt to improve residents' health. Health is affected by psychological factors, such as happiness and emotions. Therefore, this study investigates the effects of healthy city program performance on individuals' emotions, as well as the correlation between healthy city program performance and emotions using personal happiness index as a parameter. We conducted a questionnaire survey of residents in areas implementing healthy city projects. A total of 596 responses were obtained. We used structural equations to analyze the relationship of structural influences. Results showed that healthy city program performance had significant static effects on emotion. This observation shows that healthy city programs decrease local residents' negative emotions, such as stress and depression. Therefore, healthy city programs stabilize residents' emotions by increasing health friendliness. To improve the performance of healthy city programs, it is necessary to mitigate health risk factors and positively affect individuals' emotions.
