Conjoint analysis is a set of comprehensive and analytical methods that can be used to analyze consumers' preference on product attributes. The purpose of this research is to find out consumers' preference toward attributes of instant noodles. Four important instant noodles' attributes, flavor, price, package and brand, are been chosen to be our factors. Through empirical study, the most preferred attributes of instant noodles are Japanese style flavor, price range between NT$11 to NT$25, bag package, and Vi-Li brand. We hope that our research can be useful references for instant noodles manufactures while conducting product marketing strategy.
