Abstract:Based on a detailed review of the literature,the study analyzed the survey data of public attitudes towards transgenic technology in Chengdu,Wuhan and Suzhou and explored the formation path of public attitudes towards GM technology based on information dependence by structural equation.It is found that authoritative dependence,media dependence,learning dependence and interactive dependence can sensitively affect risk perception by interacting with subjective knowledge,scientific rationality and social rationality,thus affecting public attitudes towards GM technology.Therefore,the key to risk communication of GM technology in the future lies in the establishment of the legitimacy of knowledge path,the strengthening of authoritative information mechanism,the construction of media scientific discourse,and the cultivation of scientific rational literacy.
