Abstract:The smooth application of national advanced technology innovation is related to the lifeblood of a country's scientific and technological development. Relying on the Public Security Innovation Challenge, leading the innovation, development and application of public security emergency rescue is an important channel for the United States to promote national innovations, enhance social innovation ability, and realize the advanced applicable technology breakthrough of national public security emergency rescue. Through the analysis of the development history, key areas and competition mode of the Public Safety Innovation Challenge of the American Public Safety Communication Research Laboratory (PSCR), it is concluded that the PSCR Challenge has features like clear objectives, keeping up with development, transparency of the competition system and clear property rights. In view of the current situation and deficiency of China's emergency rescue system, technical equipment and industrial development, from the point of view of government guidance, results transformation, race system transformation, exercise pilot, etc., this paper puts forward some suggestions for promoting the innovation ability of advanced technology of public security emergency rescue around the Innovation Challenge in China in the new era, with a view to providing the latest ideas for researchers in relevant fields in China.
