Tax or subsidy? The impact assessment of environmental policies on carbon allocation and emissions abatement of prefabricated construction supply chain.

The construction sector, as the prime culprit that aggravates greenhouse gas emissions, has initiated transitions in construction methods for emissions abatement. In such a context, prefabricated construction has been widely promoted in developing countries. This paper assesses the effects of three environmental policies: carbon tax, green subsidy, and unit subsidy on carbon allocation and emissions abatement of prefabricated construction supply chain (PCSC) consisting of a prefab manufacturer (PM) and a project developer (PD).

Structural effects of provincial digital economy on carbon emissions within China: A multi-region input-output based structural decomposition analysis.

The digital economy, serving as a new engine to boost China's economic growth, inevitably affects carbon emissions given both its green features and its potential demands for energy inputs. To investigate the province-level impacts of the digital economy on carbon emissions, this study splits the digital industry from the multi-regional input-output table, and adopts a downscale structural decomposition analysis to reveal the technological, structural, and scale effects of the digital economy on carbon emissions. The results show that: (1) the expansion of digital economy increased 186.

Green recovery in the wake of public health emergencies: Policy instruments and their effects in China.

Numerous studies have discussed the economic impacts of the COVID-19 pandemic in recent years. However, the effectiveness and trade-offs of diverse countermeasures still need to be investigated, particularly under the long-term goal of low-carbon transition, which is crucial for understanding the potential impacts of the future public health emergency (PHE) related economic crisis. Given that China still faces big pressures from the potential PHE and carbon neutrality, this paper assesses the effectiveness of policy instruments in restoring the economy and advancing green development after the PHE using the Dynamic Stochastic General Equilibrium framework.

Determinants of the embodied CO transfers through electricity trade within China.

There is unequal spatial distribution of resource endowment, population density, industrial structure, and economic development with diverse differences in labor, energy, and capital productivities in China. However, previous studies paid little attention to the determinants of CO transfers embodied in electricity trade. In this study, we use both the absolute and comparative advantage theories to reveal the determinants of embodied CO transfers through electricity trade within China.

Water-saving co-benefits of CO reduction in China's electricity sector.

Electricity sector is the largest CO emitter and water user in China's industrial sectors. The low-carbon transition of China's electricity sector reduces its cooling water consumption. Here we firstly quantify CO emission and virtual water embodied in electricity trade with Quasi-Input-Output model.

Managing water-land-food nexus towards resource efficiency improvement: A superedge-based analysis of China.

Challenges at the intersection of water conservation, land protection, food security, and economic growth cross industrial boundaries, and also involve synergies with multiple policy domains. Despite this, little is known about how system heterogeneity affects water, land, and food (WLF) consumption performance at a sectoral level. This study integrates superedge analysis with a flow interaction network, elasticity theory, and utility analysis to detect the WLF nexus with regard to resource efficiency gains.

Causal complexity of environmental pollution in China: a province-level fuzzy-set qualitative comparative analysis.

Environmental problems are endowed with the causal complexity of multiple factors. Traditional quantitative research on the influencing mechanism of environmental pollution has tended to focus on the marginal effects of specific influencing factors but generally neglected the multiple interaction effects between factors (especially three or more). Based on the panel data of 30 Chinese provinces between 2011 and 2020, this study employs fuzzy set qualitative comparative analysis (fsQCA) - which can provide a fine-grained insight into the causal complexity of environmental issues - to shed light on the influencing mechanism of environmental pollution.

Evaluating the impact of highway construction projects on landscape ecological risks in high altitude plateaus.

In China and other countries, many highway projects are built in extensive and high-altitude flat areas called plateaus. However, research on how the materialisation of these projects produce a series of ecological risks in the landscape is very limited. In this research, a landscape ecological risk analysis model for high-altitude plateaus is proposed.

A Hybrid Framework for Direct CO Emissions Quantification in China's Construction Sector.

Carbon emission quantifications in China are not consistent, with many standards and methods having been used over the years. This study identified the non-consideration of China-specific technology and databases as a factor limiting comprehensive quantification. The study aimed to comprehensively quantify regional direct CO emission in the industry using a hybrid of economic and environmental data.

Unfolding the synergy and interaction of water-land-food nexus for sustainable resource management: A supernetwork analysis.

Given the large amounts of water, land, and food embodied in the trade of goods and services, a key step in decoupling extensive resource consumption from the economic system is to understand the full impact of socioeconomic development on the water-land-food nexus. This study integrates input-output analysis, ecological network analysis, and Dempster-Shafer evidence theory into a supernetwork model to detect the water-land-food nexus among economic sectors with an aim to explore effective strategic paths for resource management and to facilitate the construction of a resource-saving society. Results show that most sectors of China are resource inefficient and that all resource systems are unsustainable as reflected in the low performance of their Finn's cycling index and system robustness.

Co-Benefits Analysis of Buildings Based on Different Renewal Strategies: The Emergy-Lca Approach.

Many cities have encountered challenges associated with rapid urban development, population growth and aging, in which urban renewal has become a promising option. Different renewal strategies, such as redevelopment, refurbishment and conservation, not only contributes to quality improvement and energy consumption reduction of dilapidated urban area, but also to greenhouse gas (GHG) emissions mitigation. Such integrated benefits are often termed as co-benefits.

Assessing the total factor performance of wastewater treatment in China: A city-level analysis.

China is currently facing huge challenges in mitigating water shortages and protecting water bodies. The inferior wastewater treatment of the country has become the main barrier impeding regional water pollution control and sustainable economic development. Therefore, creating an overview of the current performance and weaknesses of city-level wastewater treatment is crucial and beneficial for exploring the driving factors for improvement.

Sustainability accounting of neighborhood metabolism and its applications for urban renewal based on emergy analysis and SBM-DEA.

Rapid urbanization exacerbates urban metabolic activities associated with irreversible environmental degradation. Evaluating urban metabolic performance is an effective method to meet targets for sustainable development in contemporary urban areas. Neighborhoods, which are regarded as the basic parts of cities, can detail the metabolic structure and interactions from a bottom-up perspective.

Unfolding interregional energy flow structure of China's construction sector based on province-level data.

The construction sector is a critical part in achieving energy conservation targets in China, as it accounts for approximately 30% of the annual national energy supply for building construction. Therefore, this study integrates multi-regional input-output analysis and ecological network analysis to track energy fluxes and pathways from the construction sector, aiming to facilitate the configuration of the energy-flow structure and improve understanding of the region's responsibilities. Results of a spatial distribution analysis show that the eastern area of China leads in fossil energy consumption (e.
