Despite recent voluntary climate change reporting (VCCR) initiatives, such as the Carbon Disclosure Project (CDP), Chinese companies continue to lag behind their global counterparts. This research contributes to the existing literature examining the effects of CEO background (specifically academic, foreign and political background) on corporate decisions to engage in VCCR. The data sample consists of Chinese listed companies that participated in CDP surveys during 2010–2017 (1041 final firm-year observations). The study's descriptive findings reveal that most Chinese companies are reluctant to report their climate change information to the CDP as only 12% of Chinese companies participated in the CDP annual survey during the study period. However, using a logistic regression model, we find that CEOs with academic experience, foreign exposure and political connections positively affect firms' decisions to engage in VCCR. The results remain robust when we use the propensity score matching technique to account for sample selection problems. Overall, the results are interpreted within the theoretical insights of the upper echelons perspective. [ABSTRACT FROM AUTHOR]

To mitigate the detrimental effects of climate change exacerbated by excessive carbon emissions, China has introduced a series of environmental regulations designed to promote low-carbon technology diffusion among enterprises. The existing literature ignores the heterogeneity of the scales of enterprises, making it extremely difficult to put forward targeted policies for enterprises of different scales. In this study, we employ a complex network-based evolutionary game approach to analyze the effect of environmental regulations on the diffusion of low-carbon technology, and thereby determine the relationship between the degree of diffusion and the strength of regulations at different scales of enterprise. The results revealed that with respect to the degree of diffusion, there are significant differences in the sensitivity of enterprises in 20- and 100-scale networks to the imposition of three types of environmental regulation (innovation subsidy, carbon tax, and punishment). When the scale of the network is fixed, fluctuation in the change in degree becomes larger, and even irregular, with an increase in enterprise scale. With an increase in network scale for small, medium, and large enterprises, the range of variation in the degree of diffusion becomes smaller. In small, medium, and large enterprises, when the scale of the network increases from 20 to 100, the degree of diffusion will increase in response to the same strength of innovation subsidy, carbon tax, and punishment. With an increase in innovation subsidies, the diffusion degree of large enterprises will improve slightly. Moreover, for large enterprises, increasing the strength of punishment has no obvious effects with regards to improving the degree of diffusion. At all scales of enterprise, in both the 20- and 100-sacle networks, the degree of diffusion will increase with an increase in the strength of the carbon tax. [ABSTRACT FROM AUTHOR]
