Existing Industrial Park value evaluation stays in the manual scoring mode, which is mostly based on traditional mathematical statistics, and is not intelligent and standardized. In view of the shortcomings of existing technologies, using ontology related technologies, the ontology concept of Industrial Park is defined, the concepts of related categories of Industrial Park is abstracted and defined around the influencing factors of Industrial Park value evaluation based on the object relationship and attribute, the domain ontology model of Industrial Park is established to form the knowledge ontology of Industrial Park. On this basis, the calculation rules of Industrial Park value evaluation are constructed, and the value evaluation model of Industrial Park is established. The research results can carry out quantitative value evaluation for different types of Industrial Parks, which provides ideas for the research of Industrial Park value evaluation, It has certain reference significance.
