Abstract

The invention provides an investor emotion index construction method, a heterogeneous subject market simulation method, equipment and a medium. The investor emotion index construction method comprises the following steps: selecting a plurality of first-class investor emotion indexes from candidate investor emotion agent indexes through correlation analysis; mining and analyzing the stock comment text through a text mining method to obtain a second type of investor emotion indexes; and performing principal component analysis on the plurality of first-class investor emotion indexes and the second-class investor emotion indexes to obtain the investor emotion index. The investor emotion index provided by the invention is constructed by principal component analysis of a traditional investor emotion agent index and an investor emotion index obtained by text mining, and the investor emotion index can more effectively realize measurement of the investor emotion.
