Objective　To study the subject domain knowledge of clinical education of pedi-atrics in our country with multivariate statistical analysis and social network study， research on the domain subject distribution and knowledge cluster， and then built visualized knowledge-mapping， so as to predict and guide the developmental trend in this field. Methods　We searched the CNKI with MESH keywords “（pediatrics OR children OR infants） AND clinical education OR bedside education OR interview of clinics” in March， 2013. 679 articles were enrolled in and then imported into Bicomb. After core keywords had been identified by Bicomb， a word text matrix and co-occurrence matrix of words to articles were built. Systemic clustering of the co-occurrence matrix was finished by SPSS 20.0， leading the strategic plot to be built. Then draw visualized network in Ucinet 6.0. Results　Totally 679 articles about pediatrics education were included. The number of core keywords was 66， and the lowest frequency of core keywords was 5. With multivariate statistical analysis and social network study， the visualized domain knowledge-mapping was successfully built， and it directly reflected the structure of subject knowledge-mapping of pediatric clinical education in our country， and then key clusters were formed， in which the clusters of “participation model of clinical education” and “applications of clinical education” had been well developed， and had been the dominant subject in pediatric clinical education. Whereas the unbalanced developed cluster of “Exploration in reformation of clinical edu-cation” was now in rapid development with the introduction of new technology and innovative teaching model. At the same time， the “nursing clinical education” cluster has been separate cluster， but needed further and enhanced research. Conclusion　The well developed subjects of “participation model of clinical education” “applications of clinical education” stood in the center of the subject do-main knowledge-mapping， and with several clusters following. And the study of reformation of clinical education makes a great contribution to the progress of the subject. The nursing teaching needed bal-anced development.
