Research on Management Over-optimistic Measurement:Based on Text Sentiment Analysis

Guo-tong Wu


Over-optimism managers have an important impact on corporate financing decisions.Based on the text sentiment mining technology, this paper calculates the optimism of management by constructing the emotional lexicon and using the frequency of optimistic and pessimistic vocabulary in the PFP language statistical annual report. In this paper, by constructing a theoretical model reflecting the degree of optimism of management, the residual of the model is used as the proxy variable of management over-optimism, and the rationality judgment is carried out, which provides a good research tool and method for the subsequent investigation.
