The Risk Analysis Council of China Association for Disaster Prevention was issued a registration certificate by the Ministry of Civil Affairs of the People's Republic of China on September 12, 2003, and was announced in Beijing in August 2004. It is a national academic organization engaged in multidisciplinary risk analysis research in China. Extensively unite risk researchers from all walks of life to raise the burden of risk analysis and management in China.

With the rapid development of China 's economy and society, all walks of life are facing increasing risks. Some gradually evolved into disasters, resulting in a certain loss of people 's economic and property, and having a great impact on economic and social development. For example, this year 's sudden coronavirus epidemic not only poses a huge threat to people 's lives and health, but also has a huge impact on China 's economic and social development, at the same time, has a major impact on the world economy, and this impact is continuing. How to effectively identify risks, control risks, prevent risks, resolve risks, and carry out effective risk control is the major responsibility of risk researchers and managers in China. In order to continuously promote the development of risk analysis and risk management in China, the professional committee of risk analysis of China Disaster Defense Association has successfully held eight annual sessions in 2004 in Beijing, 2006 in Chengdu, 2008 in Guangzhou, 2010 in Changchun, 2012 in Nanjing, 2014 in Hohhot, 2016 in Changsha, 2018 in Xi'an, and the ninth annual session was held in the beautiful metropolis-Tianjin in October 2020.
