Article Synopsis
  • China is actively tackling climate change by committing to international environmental protection, with industrial enterprises playing a key role in green development.
  • A study using micro panel data from 235 prefecture-level cities in China finds that stricter environmental regulations reduce resource misallocation in manufacturing sectors.
  • The analysis reveals that these regulations help optimize resource allocation through effects like improved factor flow and competition, particularly benefiting eastern and high-industrialization cities, while suggesting stronger government oversight as a countermeasure.

Digitalization and greening are two major characteristics of economic and social development, and promoting the deep synergy of these two factors has significant practical relevance for employment. However, the question of whether synergy between digitalization and greening promotes or hinders employment has not been answered in the literature. Therefore, a synergistic framework was first constructed for urban greening and digitalization based on green pulling and the digital empowerment mechanism.

The coupling relationship between land-use carbon emissions (LCE) and ecological environmental quality (EEQ) is critical for regional sustainable development. Rapid urbanization promotes a notable increase in LCE, which imparts significant stress on EEQ. This study used land use and cover change (LUCC) and Open-Data Inventory for Anthropogenic Carbon dioxide (ODIAC) data from the urban agglomeration in the middle reaches of the Yangtze River (UAMRYR) to evaluate LCE, applied a remote sensing ecological index (RSEI) model to calculate EEQ, and combined gravity and centroid movement trajectory models to analyze the spatiotemporal evolution characteristics of LCE and EEQ.

Introduction: Urban green space is one of the most closely related ecosystem services to residents' lives, and it can be regarded as a preventive public health measure. Residents living in parks and other green environments can help improve their physical and mental health, reduce stress and even prevent crime and violence. Therefore, based on the actual situation in China, this paper analyzes the relationship between urban green space and the health of middle-aged and older adults and its mechanisms.

This paper took the panel data of 1052 heavily-polluting listed companies from both the Shanghai and Shenzhen Stock Exchange from 2010 to 2017 to empirically analyze the impact of environmental regulation (ERG) on firm performance (FP). The article introduces a mediating effect model to test the mediating role of corporate tax burden (ETR) within the relationship between ERG on FP. The results showed that: (1) ERG has exerted a significant enhancement effect on the performance of heavily polluted firms via the ETR reduction mechanism.

Pyrolysis oils have attracted a lot of interest, as they are liquid energy carriers and general sources of chemicals. In this work, gas chromatography with flame ionization detector (GC-FID) and two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC-TOFMS) techniques were used to provide both qualitative and quantitative results of the analysis of three different pyrolysis oils. The chromatographic methods and parameters were optimized and solvent choice and separation restrictions are discussed.

The ability of ultraviolet (UV) light to inactivate viruses is well established. However, attempts to apply this to the manufacture of pharmaceutical proteins have been limited by incomplete treatment, low capacity or excessive dilution. Effective processing of large-scale batches of UV-opaque protein solutions has been achieved using a continuous-flow device.
