However, few articles discuss this phenomenon in the medical academia from a knowledge sharing perspective. This study examined how knowledge sharing networks were constructed among cardiovascular physicians in Taiwan. This study used Social Network Analysis to analyze survey data (N= 119, response rate＝61％) and presented the knowledge sharing structures when they performed operations. Analysis of the knowledge sharing networks interactions was carried out by applying measures of the logistic regression model and the multiple regression model. The results show that the more the physicians have international conference keynote speakers experience, the more the physicians earn in-degree centrality scores. This analysis suggests that theses high in-degree centrality scores physicians have more power and influences inside the knowledge sharing networks. The results also show that the more the physicians have national research projects leader experience, the more the physicians earn betweenness centrality scores. This analysis also suggests that theses high betweenness centrality scores physicians have more power to promote and dominate the chance of the transmission of correct and competitive medical information inside the knowledge sharing networks. This study suggests that to improve clinical performance, senior administrators should undertake proactive efforts to coordinate knowledge sharing across physicians and connect these physicians groups to promote more rapid dissemination of useful knowledge.
