ABSTRACTChina's economic growth target (EGT) embodies the typical characteristics of extensive development model. Based on the panel data of Chinese cities from 2004 to 2019, this paper examines the impact of EGT on pollution emissions. The results show that China's EGT has significantly increased environmental pollution. Especially before 2013, in order to speed up economic growth and cope with the pressure of the financial crisis, various regions tend to set higher EGT, leading to the aggravation of environmental pollution. After 2013, the promoting effect of EGT on environmental pollution is significantly weakened. Urban heterogeneity analysis shows that the impact of EGT on environmental pollution is different in different cities. The promotion effect of the EGT on environmental pollution is more evident in the western, northeastern, non‐administrative center and resource‐based cities. The industrial structure, technical intensity of industry and effective allocation of production factors are important influencing channels for EGT to affect environmental pollution. Therefore, properly handling the contradiction between economic growth pressure and environmental governance is the key to China's sustainable economic development.

Purpose
Based on the Cognitive Appraisal Theory of Stress, this study aims to reveal the mechanism of peer abusive supervision on bystander proactive behavior through two different paths: bystander assertive impression management motivation and bystander defensive impression management motivation. Besides, the moderating effects of bystander uncertainty tolerance on the two paths are also explored.


Design/methodology/approach
In this study, 438 employees and their direct leaders from eight Chinese companies were surveyed in a paired survey at three time points, and the empirical data was analyzed using Mplus 7.4 software.


Findings
Peer abusive supervision leads bystanders to develop assertive impression management motivation and, thus, to exhibit more proactive behaviors. At the same time, peer abusive supervision also causes bystanders to develop defensive impression management motivation, which reduces the frequency of performing proactive behaviors. In addition, this study finds that bystander uncertainty tolerance plays a moderating role in influencing bystander assertive impression management motivation and bystander defensive impression management motivation in response to peer abusive supervision.


Originality/value
Starting from the bystander perspective, this study verifies the double-edged sword effect of peer abusive supervision on bystander proactive behavior as well as the mechanism of differentiated effects through cognitive appraisal, which broadens the scope of the research on abusive supervision, and deepens the academic understanding and development of the Cognitive Appraisal Theory of Stress. At the same time, it also provides new ideas for organizations to reduce the negative effects of workplace abusive behavior.

Purpose
The purpose of this study is to reveal the mechanism of humble leadership inducing abusive supervision from the low-status compensation perspective, examining the mediation role of leader perceived thread to status. Besides, the moderation effect of regulatory focus on the mediation path is discussed.


Design/methodology/approach
This study conducted a three-wave longitudinal survey. The data was collected from 438 leaders and their employees in five Chinese enterprises. This study used Mplus 7.4 and adopted a bootstrapping technique for data analysis.


Findings
Humble leadership has a positive effect on leader perceived threat to status. Leader perceived threat to status plays a mediation role between humble leadership and leader abusive supervision. Leader regulatory focus is the "gate valve" that humble leadership fosters leader abusive supervision. That is, when the leader promotion focus is high, leader perceived threat to status bred by humble leadership is low, resulting in less abusive supervision. When the leader prevention focus is high, humble leadership brings relatively more abusive supervision through perceived threat to status.


Originality/value
This study explores why humble leadership breeds abusive supervision behaviors and reveals the mechanism behind the negative effect of humble leadership based on low-status compensation theory. This study not only promotes the continuous development of the field of humble leadership research through empirical research but also provides guidance for effectively suppressing the negative effects of humble leadership, promoting strengths and avoiding weaknesses and suppressing inappropriate management behaviors in management practice.

BACKGROUND: Ground-level ozone (O(3)) pollution is currently the one of the severe environmental problems in China. Although existing studies have quantified the O(3)-related health impact and economic loss, few have focused on the acute health effects of short-term exposure to O(3) and have been limited to a single temporal and spatial dimension. METHODS: Based on the O(3) concentration obtained from ground monitoring networks in 334 Chinese cities in 2015–2018, this study used a two-stage exposure parameter weighted Log-linear exposure-response function to estimate the cause-specific mortality for short-term exposure to O(3). RESULTS: The value of statistical life (VSL) method that were used to calculate the economic loss at the city-level. Our results show that in China, the national all-cause mortality attributed to O(3) was 0.27(95% CI: 0.14–0.55) to 0.39 (95% CI: 0.20–0.67) million across 2015–2018. The estimated economic loss caused by O(3) was 387.76 (95% CI: 195.99–904.50) to 594.08 (95% CI: 303.34–1140.65) billion CNY, accounting for 0.52 to 0.69% of total reported GDP. Overall, the O(3) attributed health and economic burden has begun to decline in China since 2017. However, highly polluted areas still face severe burden, and undeveloped areas suffer from high GDP losses. CONCLUSIONS: There are substantial health impacts and economic losses related to short-term O(3) exposure in China. The government should pay attention to the emerging ozone pollution, and continue to strengthen the intervention in traditional priority areas while solving the pollution problem in non-priority areas.
