Extreme high temperatures and corporate low-carbon actions.

Greenhouse gas emissions are considered the culprit of extreme high temperatures, and low-carbon transformation has become a global consensus. The low-carbon action by enterprises is an inevitable choice if they are to adapt to economic and social needs. Green innovation is an important measure for enterprises to respond to the challenges of low-carbon transformation. This study mainly discusses the causal relationship between extreme high temperatures and green innovation of enterprises. Using China's industrial enterprise database, we construct county-annual panel data from 2000 to 2013. Results show that extreme high temperatures improve the level of green innovation of enterprises. After a series of robustness tests, the results remain. Mechanism analysis shows that extreme high temperatures increase the environmental concerns of the government, the public, and society, thus strengthening government regulation, public participation, and social supervision as well as encouraging enterprises to carry out green innovation. Our heterogeneous analysis shows that in the eastern region with a high level of legal system and economic development, it is easier to promote green innovation for enterprises. In addition, large-scale enterprises are more willing to carry out green innovation after experiencing a heat wave.

Health risks from extreme heat in China: Evidence from health insurance.

Global warming has accentuated the effects of extreme heat on health. Health insurance, functioning as a risk management tool, has the potential to alleviate these impacts. Consequently, this paper investigates the correlation between extreme heat events and the demand for health insurance in China. Using data from the China Health and Nutrition Survey, we have observed a substantial increase in the likelihood of residents purchasing health insurance during extreme heat events. To be specific, for every extra day of extreme heat events annually, there is a 0.3% increase in the probability of purchasing health insurance. This effect is not uniform across different demographic groups. It is particularly pronounced among middle-aged and elderly individuals, rural residents, those with lower educational levels, higher income brackets, and individuals residing in underprivileged areas with limited access to green spaces and healthcare facilities. Furthermore, our study indicates that the increased frequency of extreme heat events not only impacts individuals' physical health but also triggers negative emotions, which in turn drive risk-averse behavior related to health insurance purchases. These findings carry substantial policy implications for mitigating the economic consequences of climate change.

Relationship Between Dietary Knowledge, Socioeconomic Status, and Stroke Among Adults Involved in the 2015 China Health and Nutrition Survey.

Stroke is a public health threat that requires urgent attention in China. Nutrients have individual significant impacts on the prevalence of stroke. However, little research has been conducted on the impact of dietary knowledge on stroke and whether the impact is potentially heterogeneous under the effect of socioeconomic status. This study used the 2015 Chinese Health and Nutrition Survey to explore the impact of dietary knowledge and socioeconomic factors on populations suffering from stroke. Results indicated that risk of stroke decreased significantly with increasing dietary knowledge score. Additionally, the impact of dietary knowledge scores on the prevalence of stroke has obvious heterogeneity. First, dietary knowledge scores significantly influenced low-income groups and individuals with low educational levels. Second, the risk of stroke in females is more affected by dietary knowledge. Third, for people living in different areas, dietary knowledge determines whether rural populations suffer from stroke.
