Fig. 1: Distribution curve of coefficient α after random treatment.

The figure illustrates the distribution of regression coefficients obtained by replicating the regression process 5000 times, where each firm impacted by CTAIS-3 is transformed into a random event. The regression coefficient of CTAIS-3 on corporate financial restatements is estimated through this randomization process. The x-axis represents the coefficient of the random event. The y-axis on the left represents p-values ranging from 0 to 1. The y-axis on the right represents the kernel density, corresponding to the kernel density plot. All regressions include firm-level and province-level controls as defined in Supplementary Table 1, with firm and year-fixed effects included in the analysis. Figure 1 shows that the coefficient distribution is close to the standard normal distribution with a mean of 0. Source: Calculated based on data from the CSMAR database.
