Making the most of the industrial network to reduce management costs and increase competitiveness has gained a lot of attention among enterprises lately. In traditional market research methods, the approach always puts its emphasis on the data of a single value without considering the complexity of human thoughts. Thus, it is the purpose of this paper to first define fuzzy mode, fuzzy expect value and fuzzy χ² test. Then, a new market survey is proposed to develop a more efficient survey analysis to examine the characteristics of fuzzy questionnaire and sample material. A comparison between fuzzy χ² test and traditional χ² test will be carried on at the end.
