The purpose of this research is to identify knowledge structure of marketing field from 1999to 2012. For this, 12,331 keywords that extracted from 25,146 articles of domestic journalsrelated marketing field were analyzed with keyword co-occurrence & social network analysis. To investigate the knowledge structure was carried out by the following steps. The first stepwas to identify the frequency of keywords for 14 year period(1999-2012). High frequencykeywords do not only represent marketing research but also aid in identifying the transitionprocess of marketing research when the data is analyzed chronologically. Keywords that continentlyrepresented the marketing field were identified as customer satisfaction, satisfaction, servicequality, trust. And Keywords pair, customer satisfaction-service quality, trust-satisfaction,S.Korea-USA, advertising attitude-brand attitude, S.Korea-Japan, customer satisfaction-customerloyalty, have been studied with a number of papers. The second step, central keywords in marketing research were identified by degree, closeness,and betweenness centrality, both of which are social network analysis indicators. For this,social network analysis was performed to identify the core keywords using centrality analysis. The keywords with high degree centrality were ‘trust, customer satisfaction, satisfaction, intentionto purchase, service quality, advertising’ over the entire period. The third step identified subordinate research fields in marketing through a keyword cooccurrencematrix. The identification of subordinate research fields was performed throughcommunity analysis, a method that identifies cohesive groups SNA. As a results, six cohesivesubgroups were identified through community analysis. Each of the groups consisted of keywords related to the group name–Group 1: channel distribution, Group2: customer relationshipmanagement, Group 3: organization, Group 4: advertising, Group 5: consumer behavior, Group6: brand. In the last step, identified subordinate research fields were placed on the cognitive mapdepending on both the maturity and the independence of the research areas. The structure forsubordinate research areas reveal through that. Following that map, Group2 were attractiveresearch area, Group3 was mature research area, and Group1, Group5 was unconstructedareas for which further research is required. Group4, Group6 were independent research area. The results of this study provide valuable insights to understand the knowledge structure ofmarketing field. In addition, this study suggest the further research direction for marketingresearchers.
