With the development of society, various kinds of safety risks have become increasingly prominent. For example, oil fields in the petrochemical industry have a wide range of locations and have a high risk of damaging the ecological environment. Beaches and offshore operations are vulnerable to storms;Refining and chemical enterprises are characterized by high temperature and pressure, flammability and explosive, toxicity and harmfulness, which are extremely easy to cause major accidents such as fire, explosion and poisoning;Sales enterprises are located in both urban and rural areas, making management difficult. Oil and gas leakage accidents are easy to occur in long-distance pipeline transportation, and there is the risk of drilling and oil theft. The risks existing in the characteristics of these industries need to be controlled by standardized, scientific, standardized and information-based means. If the operation of HSE management system is not effectively combined with the production and operation of the enterprise, scientific and systematic performance assessment and incentive measures are not available, and the risk control in the production and operation process is insufficient, accidents will be caused. On the contrary, if the HSE performance is improved, HSE accidents will be eliminated. This paper starts with the audit of the HSE system at the end of sales of a petrochemical company, and puts forward guiding opinions on the construction and operation of the HSE system.展开更多

According to the evaluation content and principles,the paper constructs the evaluation indicator of five subsystems: " economic management", " economic decision-making", " implementation of economic policy", " economic development",and " honest and upright administration". Through the field survey of some county in Chongqing,evaluation indicator is screened. According to the expert questionnaire,it uses the Hierarchy Analysis Process method to construct the judgment matrix and calculate the indicator weight and thereby build evaluation indicator system. It focuses on traditional indicators and evaluation indicator of sustainable development to construct a new,more complete evaluation indicator system.展开更多
