Note(s): Table 11 employs the secondary indicators of digital transformation, intangible asset digital transformation and industry median-adjusted digital transformation as alternative proxy for digital transformation. Column (1)-(3) employs the secondary indicators of digital transformation: digital underlying technology (Tech), digital infrastructure construction (Infra) and digital technology application (App), replacing the digital transformation indicator in Model 2 and repeating the regression. Column (4) uses intangible asset digital transformation as an alternative proxy for digital transformation and repeats regression following Model 2. Column (5) uses industry median-adjusted digital transformation variable (IDT) as an alternative proxy for digital transformation and repeats regression following Model 2. All variable definitions are provided in Appendix Table 1. All models are controlled for industry and year effects
t-values are in parentheses. ***p < 0.01, **p < 0.05 and *p < 0.1
