As the representative of national brands, the development of time-honored brands has always been highly concerned. Although the research in the field has achieved certain results, the research is rather decentralized and lacking systemic integration, which is not conducive to the researchers to grasp the research portrait of the time-honored brands and the future direction of research. In view of this, this paper uses CiteSpace software to carry out bibliometric analysis and describes the knowledge map of time-honored brand's research. Based on the results of bibliometrics ,this paper divides the researches of time-honored brands into three stages: exploration stage, maturity stage, and deepening stage. Then this paper conducts in-depth analysis of the research topics in each stage. On the basis of summarizing the researches of time-honored brands and drawing on the lens of long-term brand management, this paper looks forward to the future research of time-honored brands from the following three aspects: Identify the core resources of the old brands based on its history. Explore the method to balance heritage and innovation at present. Carry out the digital transformation and marketing innovation research of time-honored brands for their future development.
