On the basis of analyzing the relations among big data, fans economy and star nodes in social network in detail, aiming at the deficiencies of a star node mining algorithm proposed by us, a big data and fans economy oriented improved algorithm based on acquaintance immunization is put forward. Multiple contrast experiments on Karate club network and Dolphin social network demonstrate that the improved algorithm is superior to the old one from the quantity, degree and influence aspects of the mined star nodes.
