Abstract:Based on people's stereotype of scientific and technological power, this paper explores how brands from non scientific and technological power break through the "country of origin bias" from the perspective of scientific and technological innovation and consumer thinking. Using the empirical research method, this paper proves that compared with the brands from non scientific and technological powers, the brands from scientific and technological powers will make consumers have higher repurchase intention. The realization of technological innovation in scientific and technological innovation can effectively reverse the negative impact of non scientific and technological powers on consumers' purchase behavior; Consumer constructive thinking will also adjust consumers' inherent country of origin effect. Finally, according to the empirical research results, this paper puts forward specific breakthrough path suggestions from the national level, industry level and consumer level.
