Regression analysis reveals a significant positive correlation between investor factors and total factor productivity in A-share companies.
This paper briefly introduces the total factor productivity (TFP) and then analyzes A-share listed companies between 2017 and 2022. The regression analysis method is used to study the investor factor and TFP. The results showed that investor research behavior, shareholding ratio, grouping behavior, and digital technology level were significantly positively correlated with TFP.
