Place attachment is a hot topic in place study which is defined as an individual's cognitive or emotional connection.However,place attachment study is little related to event venues.The present studies treat events as an attribute of event host community(destination) to conduct research on the place attachment between people and the destinations,but little concerns about event venues themselves.As an inductive qualitative method,grounded theory is appropriate for situations where there is no pre-existing theory.This study considers that little theory existed related place attachment to event venues;and grounded theory is an appropriate methodological tool.Taking the International Horticultural Exposition,2011,Xi'an(Expo 2011 Xi'an China) and China Import and Export Fair Complex as cases,this paper collects first-hand data by observation and interviewing to analyse event-goers' behaviors,attitudes and emotions.Refining and concluding the dimensions of event place attachment based on grounded theory through three analytic procedures,i.e.,open coding,axial coding and selective coding,this study contracts a conceptual analytic model of place attachment in event venue which has four dimensions: person,society,place and event.Finally,the paper compares the differences of place attachment between Festival & Special Event Venue(FSEV) and Convention & Exhibition Complex(CEC) based on the four-dimension model.The results are shown as follows.Event-goers in FSEV regard themselves as "recreationists",and FSEV is characterized by "rooting venue" which is considered as a "recreation place",event-goers are inclined to show an emotional bonding with the event place;while event-goers in CEC regard themselves as "commuters",CEC is featured by "tooling venue" which is considered as a "consumption place" to event-goer,and functional bonding is more significant than emotional bonding for event-goers attached to the event venues.The difference of place attachment between FSEV and CEC is consistent with the difference of the nature of FSE as leisure/recreation events and CE as business/commercial events.
