The questionnaire designed 2 types of products in 7 imaginary brands with price, labor, and environment involved. The study was quantitative research. There were 400 questionnaires distributed to consumers who live in Kunming, China in 2021. It showed the result that the demographic factors (age, gender, education, income) would not affect the consumers' buying behaviour for CSR products.
