First, the firms without digital deposit account products would have no impact on firm revenue, indicating that digital deposit accounts could not be the key factor in banking revenue. Second, the firms with high digital deposit accounts opening volume would enhance firm performance, implying that accounts could accept deposits and convert financial assets into profits effectively. Third, this study reveals that manager shareholding ratio is positively related to firm performance, which might result from that some financial institutions with higher manager shareholding ratio still have superior performance.
