  • 详情 Auditor‐client reciprocity: Evidence from firms’ green innovation and common auditors
    This study investigates whether common auditors have an impact on firms’ green innovation. Using a sample of Chinese listed firms, we find the common auditor ties to firms with green patents are positively related to focal firms’ green innovation. When examining underlying mechanisms behind such effects, we observe that our main findings are more profound for focal firms with more opaque information, communicating with auditors intensively and audited by senior auditors, which indicates information sharing serves as the plausible mechanism. Cross-sectionally, our findings are more remarkable for non-SOEs, firms with lower financial constraints, firms located in regions with environmental courts, local auditors, auditors with green auditing abilities and firms in the same industry. Further analysis suggests that the common auditor ties to firms with green patents can further improve focal firms’ environmental performance and green patent citations, which in turn boosts market share of involved audit firms. Overall, we document that common auditors have a positive spillover regarding green innovation to connected clients through transferring valuable green expertise in a legitimate way.
  • 详情 Common Ownership and Knowledge Spillovers in Developing Countries: Evidence from Chinese Listed Firms
    Common institutional ownership can enhance knowledge spillovers by increasing portfolio firms’ awareness about each other’s innovation. By investigating listed electronic hardware firms in China for 2000-2016, we find that when common ownership by mutual funds is higher between a firm pair, it is more likely that these two firms cite each other’s patents. To confirm causality, we show that even the exogenous increase in firms’ common ownership following their inclusion into the stock index still positively influences the citing likelihood. We also find that such citations are taken place in a timely manner. Additionally, this positive effect is robust when the effects of overlapping board members and common ownership by other types of institutional investors are controlled for. This effect is more pronounced among nonneighboring firms, when non-neighboring firms are close to their common owners, when common owners hold shares longer, and when firms’ executives have lower incentive to communicate (i.e., SOEs). Last, we find that common ownership by mutual funds also enhances knowledge spillovers through third-party patents. This paper deepens the understanding of knowledge spillovers among firms in developing countries.
