Abstract-This study intends to evaluate the impact of product characteristics and consumer characteristics on Singaporean consumer’s impulse purchasing behavior. Therefore, in order to conduct the study, a sample of 100 Singaporean customers has been collected randomly in 3 major shopping centres in Singapore. Meanwhile, the SPSS tool has been used to assess the relationship between the variables. Based on the chi square analysis results, there is a significant relationship between consumer characteristics ( Gender, Age, Mood, Materialism, Shopping Enjoyment, Impulse buying tendency ) and Singaporean consumers’ impulse purchasing behavior except for the variable of materialism which has no significant relationship with Singaporean consumers’ impulse purchasing behavior. Moreover, there is also a significant relationship between product characteristics and consumers’ impulse purchasing behavior in Singapore.
