Abstract: Currently, the domestic market for vacuum coating equipment technology is experiencing continuous expansion, while international trade competition in this field is intensifying. Against this backdrop, conducting TBT research becomes increasingly important. To analyze the competitive technology of vacuum coating equipment through TBT analysis, data visualization technology is employed to explore the visualization process using both domestic and foreign TBT data (notifications and standards) as the basis. The focus lies on empirical image analysis of value results in this field, particularly emphasizing the relationship between the purpose of TBT notification & technical content, standard category & theme. The visualization results of the trinity of literature data, patents and TBT data are formed. This transformation aims to establish an industrial standard system and roadmap planning in Guangdong province by fully analyzing the competition status and development prospects of vacuum coating equipment while indicating technological directions within this domain.
