PurposeThe paper aims to (1) explore the positive and negative sociocultural, economic, and environmental impacts on satisfaction, and behavioral intentions; and (2) examine the changes in relationships among event impacts, satisfaction and behavioral intentions of host city residents before and after a major sporting event.Design/methodology/approachWe used panel data to estimate how resident responses change over time. The data were collected three months before (N before = 266) and three months after (N after = 266) the Nanjing Youth Olympic Games. Data were analyzed by confirmatory factor analysis (CFA), structural equation modeling (SEM) and invariance tests.FindingsA significant relationship exists between negative and positive perceived sociocultural, economic, and environmental impacts, satisfaction and behavioral intentions. In addition, findings suggest that the effect of the sociocultural impacts on satisfaction and of satisfaction on behavioral intentions strengthened after the event. The relationship between positive environmental impacts and satisfaction was reduced across the two points in time. Our results indicate that residents’ assessment regarding the sporting event partially changed over the whole six-month course of the study.Originality/valueThis study differs from most recent research in that it examines the sociocultural, economic, and environmental event impacts in modeling residents’ satisfaction and testing the influence of negative event impacts on residents’ satisfaction and behavioral intentions. The current study contributes to the literature by emphasizing the changes that occur regarding the relationships among event impacts, satisfaction and behavioral intentions across the same respondents over time.
