In search of sustainable strategies to improve employees’ work engagement without harming their long-term performance in the VUCA era, this study examines the impact path of subordinate moqi on employees’ work engagement based on leader–member exchange theory and organizational support theory. A total of 322 R&D staff from high-tech enterprises in Shanghai, Beijing, Shenzhen, and other cities participated in the study. The data analysis reveals that the leader–member exchange partially mediates between subordinate moqi and work engagement. Moreover, both supervisor’s organizational embodiment and perceived organizational support can positively moderate the impact of subordinate moqi on leader–member exchange. The empirical results enrich the intermediary mechanism between subordinate moqi and work engagement. Employees with subordinate moqi have better chances of meeting their supervisors’ implicit expectations, leading to a higher relationship quality with followers and increasing enthusiasm for work. The current study clarifies the theoretical and practical significance of subordinate moqi in establishing high-quality work relationships and sustainable development of organizations’ human resources.

By analyzing the China’s hazardous waste management policy and the existing problems in hazardous waste management, the elements of hazardous waste management in oil and gas exploration enterprises were identified. Based on the theory of life-cycle management under the concept of sustainable development, combined with literature research, a three-level comprehensive index system was constructed by using the AHP–entropy weight method to evaluate the hazardous waste management capability of oil and gas enterprises. It was proposed that oil and gas enterprises should further strengthen the life-cycle management of hazardous waste, strengthen the assessment of hazardous waste management capacity, continuously establish a sound hazardous waste supervision system, and actively build a hazardous waste information control platform to realize the whole-process tracking management, as well as other suggestions.

Emissions trading system (ETS) is a market-based policy tool that essentially provides economic compensation for corporate environmental measures. The Chinese government implemented pilot emissions trading in 2007. In order to evaluate the effect of the policy, we conducted a quasi-natural experiment to collect the data of 249 prefecture-level cities in China from 2001 to 2020 and applied the difference-in-difference method to explore the impact of ETS on regional industrial structure. The results show that the implementation of ETS can promote the upgrading of regional industrial structure but can hinder the rationalization of the upgrading. The results of regional heterogeneity regression suggest that the effects of ETS pilots on industrial structure upgrading in three regions of China are significantly different, with the strongest one being the western region, followed by the central and eastern regions. Finally, we put forward some policy proposals in terms of technological innovations, implementation of ETS in different regions and ETS improvement.
