title: [Regional development of patents of traditional Chinese medicine compounds on basis of cluster analysis].
abstract: OBJECTIVE
  To study current regional development and optimization schemes of patents of traditional Chinese medicine compounds.
  
  
  METHODS
  Simple statistics and cluster analysis were adopted for calculating application quantity, maintenance quantity and quantity of scientific research papers related to patents of traditional Chinese medicine compounds in different regions. On that basis, cluster analysis was used for studying current development patents of traditional Chinese medicine compounds in different regions.
  
  
  RESULTS
  The 34 regions, including Chinese mainland, Hong Kong, Macau and Taiwan, were divided into four groups by cluster analysis according to the difference in quantities of patents and research papers. The first and third region are better, the second region is medium, while the forth region is not ideal.
  
  
  CONCLUSIONS
  Different regions shall adopt suitable development schemes for the development of traditional Chinese medicine compounds according to their actual situations. Reasonable regional alliance is helpful for inter-regional win-win and co-flourishing.
