Does the pilot trading of carbon emission rights cause domestic or international pollution transfer?

The implementation of a carbon emission trading pilot policy has a positive impact on sustainable development but may lead to pollution transfer by enterprises, thereby affecting sustainability. In this study, based on the panel data of Chinese-listed companies from 2007 to 2017, the carbon emission trading pilot policy was treated as a quasi-natural experiment and the Difference-in-Differences model was used to analyze whether these companies engaged in pollution transfer under the policy shock. The results indicated: first, carbon emission trading pilots lead to pollution transfer within mainland China but not across international borders; second, the power and aviation industries exhibited significant pollution transfer phenomena, and the policy also encouraged pollution transfer by non-green transformation enterprises; third, regional heterogeneity further showed that the central region showed no signs of pollution transfer and instead experienced pollution inflow, while the eastern region exhibited significant pollution transfer.

Negative Life Events, Negative Copying Style, and Internet Addiction in Middle School Students: A Large Two-year Follow-up Study.

Through a two-year follow-up study among 2,845 middle school students, we examined the impact of baseline negative life events (NLE) on follow-up negative copying style (NCS) and Internet addiction (IA), and the mediation of NCS between NLE and IA. We found that all NLE, NCS, and IA were correlated, and that both NLE and NCS were risk factors for IA. Structural equation modeling (SEM) results showed that NLE were associated with increased NCS ( = 0.

Prevalence and Clinical Significance of Occult Pulmonary Infection in Elderly Patients with Type 2 Diabetes Mellitus.

The occult pulmonary infection is the most common complications in elderly patients with type 2 diabetes mellitus (T2DM). Since its etiological characteristics has not been clarified, infection control remains a serious problem for public health. To investigate the prevalence and clinical significance of occult pulmonary infection in elderly T2DM patients, in this study, 573 elderly patients cochallenged with T2DM and community-acquired pulmonary infection from January 2018 to December 2020 were selected in the hospitals and divided into occult pneumonia group (OP, = 249) and nonoccult pneumonia group (NOP, = 324) according to the nature of infection.

Can green credit increase firm value? Evidence from Chinese listed new energy companies.

Green credit plays a crucial role in reducing energy consumption and environmental degradation in China. Using data on China's new energy listed companies from 2007 to 2018, this study explores the impact of green credit on new energy firms' value, as well as the mediating effects of financing constraints and external supervision on the relationship between green credit and new energy companies' economic benefits. Our results suggest that green credit significantly improved new energy firms' value, and this positive impact can last over the long term.

Sustainable total-factor ecology efficiency of regions in China.

This paper presents a new index called sustainable total-factor ecology efficiency (STFEcE), which integrates the ecological footprint and human development index into the framework of total-factor energy efficiency. Compared with the total-factor ecology efficiency index, the new index can better reflect the sustainable development efficiency of a region. This study uses data from 30 provinces of China over the period 2005-2016 to measure the STFEcE.
