Abstract: By focusing on the large and above-level production safety accidents in Zhejiang Province， this paper systematically analyzes the law of accident occurrence，deeply explores the causes of accidents， and aims to put forward targeted prevention and control strategies. In terms of research methods，statistical analysis and case induction are comprehensively used to analyze the eight core accident factors. The study found that human factors dominate the accidents caused by various industries，followed by education and training factors，highlighting the serious challenges posed by human errors and lack of knowledge and skills to safety production. Environmental factors and equipment and facilities also significantly increased as an important cause of frequent accidents. Based on the above research results，the corresponding countermea⁃ sures and suggestions for accident research are put forward. The first is to build an expert database，gather top wisdom inside and outside the industry，and provide professional guidance and technical support for safe production. The second is to build a safety production database，realize the comprehensive integration and deep mining of accident information with the help of big data technology，and provide scientific basis for ac⁃ cident prevention and emergency response. The third is to emphasize the technical support ability of deepen⁃ ing the analysis and research of accident causes and accident investigation，so as to effectively promote the improvement and implementation of safety production management system with comprehensive measures， and further ensure the safety and stability of production activities. In the future，through technical empower⁃ment and innovative application，social participation and responsibility implementation，deepening acci⁃ dent investigation and research，information sharing and collaborative cooperation，publicity and education and capacity building，strengthening domestic and foreign exchanges and cooperation and other measures to promote the improvement and implementation of the safety production management system in Zhejiang Prov⁃ ince，further ensure the safety and stability of production activities，and provide useful reference for the con⁃ tinuous and stable improvement of China 's safety production situation.
