[Abstract]:From the perspective of ecology, this paper focuses on the shareholders of listed companies. By dividing the shareholders of listed companies into ecological groups, this paper depicts the niche of different types of shareholders. Based on Cathay Pacific database and CCER database, there are about 600,000 records of shareholders in four quarters from 2008 to 2014. The decision tree algorithm is applied to the statistical classification and behavior analysis of shareholders, and a fast and accurate statistical analysis method is tried. Through the analysis, it is found that the niche dimension of shareholder ownership ranking has the greatest influence on the behavior and degree of shareholders' increase and decrease, which provides the basis for further governance decisions.
