This paper, based on the panel data, measures the comprehensive efficiency of green innovation, the economic output efficiency of green innovation, the social output efficiency of green innovation, and the environmental output efficiency of green innovation of listed energy companies in China by means of the window DEA model from the perspective of the triple bottom line. Moreover, the impacts of environmental factors and random factors on the green innovation efficiency are analyzed. It is found that firstly, green innovation efficiency of listed Chinese energy companies shows a V-shaped change trend without excluding environmental factors and random factors. Secondly, environmental factors and random factors are the primary factors to promote the green innovation efficiency of energy listed companies in China. Finally, after removing the interference of environmental factors and random factors, comprehensive efficiency of green innovation of the listed energy companies in China is relatively high and the distribution is relatively concentrated, but there is a downward trend during the research period.
Health-promoting leadership has attracted a lot of attention from scholars in recent years. However, majority studies focused on theoretical arguments rather than empirical examination. Not only that, extant research often theorizes health-promoting leadership as a combination of a series of direct and explicit health-related behaviors, neglecting the potential social information it may convey to employees. Based on social information processing theory, this study empirically examines how and when health-promoting leadership can facilitate employees’ health status. Using a time-lagged data of 370 employees (i.e., matched to 51 leaders), we found that health-promoting leadership has a significant and positive influence on employees’ health status, and healthy climate acts as a linking pin. In addition, work unit structure moderates the relationship between health-promoting leadership and healthy climate. Specifically, compared with mechanic work unite structure, employees rely more on social information conveyed by health-promoting leadership when working at an organic work unite structure. This study not only extends current knowledge about the effect of health-promoting leadership, but also provides useful guidance for practitioners.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
