Abstract: The attention to S&T ethics of Chinese public has increased. 46.0% of the public believed that scientists should be responsible for the social effect of their research results, which increased 10% compared to 2007. Public paid more attention to animal experiment. The objection of that increased from 21.1% in 2007 to 29.3% in 2011. 39.8% believed that scientists' research work should be confined by social regulations, and they didn't agree that scientists could do any research just under the law. This paper suggests the government to pay more attention to S&T ethics and build more S&T ethic consultant organizations and strengthen the management system of S&T ethics.
