To explore the mechanism of deviation in the operation objectives of safety production liability insurance in hazardous chemical logistics parks, grounded theory was adopted as the research method in this study. Through systematic and in-depth interviews with multiple key stakeholders, the study aimed to capture and refine the key factors affecting the operation objectives of safety liability insurance, thereby a mechanism model was constructed for the deviation in the operation objectives of safety liability insurance in hazardous chemical logistics parks under the interaction of six main entities. The model was analyzed with a focus on elucidating its formation mechanisms. The research indicates that the mechanism of deviation in the operation objectives of safety liability insurance in hazardous chemical logistics parks can be divided into three stages: planning, execution, and feedback. At each stage, multiple entities, under the influence of external and internal stimuli, exhibit behaviors that deviate from the objectives. These behaviors, linked together, lead to phased deviations in objectives. More importantly, the deviations at these three stages are not isolated but are interconnected and cumulatively cyclical. This cumulative causal effect ultimately results in an overall deviation of the operation objectives of safety liability insurance in hazardous chemical logistics parks.
