Overwhelming evidence from prior research suggests a positive association between corporate board characteristics and carbon performance; however, very little is known about the mechanisms linking the two variables. This study attempts to fill this gap by developing and empirically testing a conceptual model that highlights the role of carbon strategy in the relationship between board environmental orientation (BEO) and carbon performance. We argue that BEO can directly and indirectly influence carbon performance through carbon strategy. Using structural equation modelling to analyse data consisting of 2,301 U.S. firm‐year observations over the 2005–2015 period, we find that the greater the BEO is, the better its carbon performance (i.e., lower greenhouse gas emissions). The results also provide evidence of the mediating effect of carbon strategy on the relationship between BEO and carbon performance. Splitting the sample into high and low carbon‐intensive industries shows a partial mediation effect in high carbon‐intensive industries and a full mediation effect in low carbon‐intensive industries. The findings of the study and its implications for scholars, policymakers, managers, investors, and environmentalists are discussed. 相似文献

This study investigates whether gender diversity on the board of directors in the United States is associated with firms' environmental performance. Under the theoretical framework of resource dependence theory, we argue that gender diversity brings a greater variety of skills to the board. Diversity allows for a healthy mix of knowledge and experience to improve the decision‐making process of the board. Using propensity score matching and controlling for endogeneity, this study uses a more rigorous statistical model than previous work. It also uses content analysis of directors' biographies to provide evidence of the role that gender diversity plays. We find gender diversity is positively associated with firms' environmental performance scores primarily in the more environmentally impacting industries. Therefore, our research provides valuable direction for those firms working to improve both their boards' gender diversity and their environmental performance. Our findings also offer insight into the mixed results of previous studies. 相似文献

This study uses the theoretical frameworks of institutional theory and comparative capitalism to demonstrate how cross‐cultural differences in national institutional frameworks are related to differences in the meaning and the nature of corporate social responsibility (CSR) and, as a result, how they create different incentives and opportunities for companies to engage in stakeholder management activities. More specifically, we draw upon the framework of “explicit” and “implicit” CSRs to investigate whether and how stakeholder management practices and programs differ between the United States and Japan. We first develop and validate a Stakeholder Engagement Activities (SEAs) scale, designed assess differences in the approach (explicit or implicit) that companies use to address a variety of common SEAs. Then we analyze data and present the results of surveys collected from 227 companies in the United States and Japan. We find that although the SEAs of American companies are characterized by strong “explicit CSR,” in contrast, the SEAs of Japanese companies exhibit strong “implicit CSR.” In the discussion that follows, we attribute these distinctions in the SEAs to differences in the configuration of political, economic, and market mechanisms in each country. The findings of this study contribute to a more nuanced understanding of the differences in prevailing CSR practices of American and Japanese companies than noted by previous researchers. From a practitioner's perspective, the findings of this study reveal that despite the global nature of CSR, stakeholder management practices are both interpreted and operationalized differently due to differences in national institutional frameworks. 相似文献
