[Purpose/significance] The reverse citation of papers citing patents is important in the study of linkage between science and technology. This paper analyzed the influence of Chinese patent on world science fields. [Method/process] The data of citations of Chinese patents referenced in articles were collected from Web of Science (WoS) of Thomson Reuters. Reverse citation frequency, technology linkage (TL), citation delay and technology cycle time (TCT) were analyzed. By the Social Network Analysis (SNA) method, the reverse citation network was constructed and the knowledge flow of technology-to-science was explored. [Result/conclusion] ］The influence of Chinese patent on world scientific research has been growing. The interaction between science and technology is the most obvious in chemistry field. Chemistry, engineering and material science fields have cited patents more, and the technology linkage (TL) is higher than other fields. Scientific papers were more likely to cite patents published within one to four years. The technology cycle time (TCT) of Chinese patents cited by scientific papers is short, with an average of 4.69 years.
