Risk prevention and hidden danger identification are important to urban safety. According to current laws and regulations on safety production and emergency management in China, the responsible subjects of safety management are those departments that are directly involved in risks and hidden dangers. In a comprehensive city there are great differences in the types and distributions of potential risks among industries. These differences should be taken into account so that targeted risk prevention and control measures can be formulated accordingly. This paper studies the distribution differences of potential safety risks in industries, proposes a concept of industry safety risk structure, defines an industry safety risk vector, and gives the quantification indexes of industry risk entropy and risk specificity by means of information entropy theory. Based on the analysis results of tens of thousands of cases it is found that determination of safety risk vector, industry risk entropy, and risk specificity is conducive to the comparative study of safety risks within and between industries and provides a basis for the classified monitoring of industrial safety risks.
