Research on the path of building carbon peak in China based on LMDI decomposition and GA-BP model.

The building sector contributes significantly to carbon emissions, impeding China's progress toward its 2030 carbon emissions peak target due to the limited utilization of renewable energy sources. This study aims to forecast the peak and timing of carbon emissions in China's construction industry to chart a low-carbon roadmap for the sector's future. Initially, an extended logarithmic mean divisia index (LMDI) decomposition model, based on the Kaya identity, is proposed to gauge the contribution levels of driving factors affecting building carbon intensity. Subsequently, a hybrid prediction model (IGA-BP) is constructed, employing an optimized two-hidden-layer neural network via a genetic algorithm, to forecast building carbon emissions and intensity. Additionally, four scenarios are outlined, each defining pathways to simulate emissions peak, carbon peak timing, and intensity within the Chinese building sector from 2020 to 2050. The research findings reveal: (1) The final emission factor of buildings primarily drives the surge in building carbon intensity, while the industrial structure stands as the most significant limiting factor. (2) Compared to alternative models, the proposed hybrid prediction model more effectively captures the evolution pattern of carbon emissions. (3) The prediction results indicate that China's building carbon intensity has reached its peak. Pathway 12 closely aligns with the sector's carbon emissions peak, projecting a peak value of 5.609 billion tons in 2029. To attain this pathway, China needs to develop more precise and feasible emission reduction strategies for its buildings. Overall, the research outcomes furnish robust references for decision-making in future efforts aimed at reducing building emissions.

EFFECT AND MECHANISM OF CHINA’S PREFABRICATED BUILDING POLICIES TO PROMOTE PATENT OUTPUT WITH CARBON-NEUTRALITY AS A TARGET

ABSTRACT Unlike cast-in-place buildings, prefabricated buildings can conserve energy and reduce pollution, diminish damage to the environment caused by construction projects, drive greening of the construction industry, and promote carbon neutrality. The prefabricated construction industry is highly developed in China. This study analyzes prefabricated building policies and patents in Chinese provinces from 2011 to 2020 and systematically discusses the impact mechanism of supply-oriented, environment-oriented, and demand-oriented prefabricated building policies on patent output from static and dynamic perspectives. Correlations between policies and patent output were analyzed in the spatiotemporal dimension from a static perspective. A system dynamics model was used to investigate the causal relationship between the enterprise, university research, and government subsystems. Simulations were conducted to determine the sensitivity of policies in different dimensions to evaluate the impact of different policy categories and dynamics on patent output. The results: (1) policies are significantly and positively spatiotemporally correlated with patent output; (2) patent output increases over time, the positive effect is enhanced when policy implementation is strengthened; and (3) the effects of different dimensional policies on patent output differ across different periods. Overall, the effect of demand-oriented policies was the most significant, followed by environment- and supply-oriented policies. Before 2020, the effects of environment- and supply-oriented policies were equivalent, but the promotional effects of supply-oriented policies became more prominent after that, and (4) sub-policies contributing to dimensional policies vary. Fiscal and financial, science and technology, and public procurement sub-policies are critical in supply-, environment-, and demand-oriented policies, respectively. The findings can contribute to a virtuous cycle of prefabricated building policies and patent output systems, and provide information to accelerate sustainable, green industrialized development of the prefabricated construction industry in China.

Mapping stakeholders' relationships management in fulfilling corporate social responsibility: A study of China's construction industry.

Businesses today face a strong call for implementing corporate social responsibilities (CSR) subject to stakeholders' multiple expectations on the creation of long-term value. However, a vast majority of companies have struggled with the challenge of stakeholder management in CSR fulfillment, giving rise to a waste of enterprise resources. This study aims to map out stakeholders' relationships in CSR fulfillment to underscore stakeholder management. 253 CSR reports published by Chinese listed construction companies from 2010 to 2021 were collected and analyzed to map the stakeholders' relationships. The results show that construction companies usually stress the importance of corporate governance and workers interest, followed by construction quality and environmental preservation in implementing CSR. They adopt three types of stakeholder management approaches: coercive, cooperative, and coordinated approaches. The study presents the latest effort in managing stakeholders' relationships in the domain of CSR research. It favors construction firms to reconsider CSR activities from the stakeholder management perspective.

Sustainable Development of Construction Industry in China

The research aims to determine the direction of sustainable development of the construction industry in China and ensure its regular and stable development. A series of data comparisons and methods of the comprehensive analysis showed that the construction industry in China, on the one hand, is a major industry with a huge scale and a significant position on the international market. On the other hand, it is also an industry with low investment in technology, high energy consumption, relatively backward engineering technology, and management. Besides, management and operation methods are relatively traditional and associated with challenges of industry development. The comparison with advanced manufacturing industries and foreign developed countries clarified the shortcomings of China’s construction industry and set the directions for future development. These include (1) active development of green building, (2) promotion of the industrialization process, (3) improvement of the technology application level, and (4) timely improvements of the relevant regulations. China also needs to adjust the industrial form of the construction industry and increase the internationalization level. Based on the methods of data description research and literature review, we identified the conditions for sustainable development of the construction industry and proved the importance of using Integrated Project Delivery [IPD] and BIM (Building Information Modeling) technology in the development of the Chinese construction industry. The research allowed us to understand the important role of technology and organization management in developing the construction industry. When we continue to learn lessons from advanced science and technology, smart organization, and management and implement them in the construction industry, only then it will develop sustainably.

Carbon emission scenarios of China's construction industry using a system dynamics methodology – Based on life cycle thinking

China is currently one of the world's major energy consumers and CO2 emitters. To save energy, and reduce consumption and carbon emissions, China proposed (at the 2020 United Nations General Assembly and Climate Summit) the introduction of stronger policies and measures for CO2 emissions to peak in 2030 and to achieve carbon neutrality by 2060. The construction industry is a major contributor to China's carbon emissions, thus research on energy saving and carbon reduction in this industry is essential. The construction industry is characterized by complex upstream and downstream industrial chains, with different energy consumption at each stage, and a long overall life cycle. We used life-cycle thinking (LCT) to analyze the carbon emissions of the whole life cycle of the construction industry and built a model by using a system dynamics method, which analyzes the carbon emission process of the construction industry at different stages. Combined with the planning and policies implemented by the construction-related departments, we identified the main indicators of policy regulation and control. We used sensitivity analysis to examine the impacts of factors of regulation and control. We also adjusted key indicators and set up different scenarios to simulate the carbon emissions based on the effort to achieve “peak carbon.” The results show that the carbon emissions of the construction industry will be reduced by 2060, achieving the goals of “peak carbon” and “carbon neutrality.” Although the construction and operation stages individually can achieve peak carbon by 2030, the whole process of the construction industry will reach peak carbon by 2045, 2038, or 2036, depending on specific aspects of the scenario considered. However, the indicators, such as the green building ratio can realize carbon emission reduction at building operation stage for 4%∼6%, but cause greater carbon emission for 5%∼7% at construction material production and transportation stage—a phenomenon called “policy island.” Therefore, the coupling of policies should be a key concern in policy formulation and implementation.

Development and Challenges of BIM in the Construction Industry in China and Australia

This article examines the application and development of Building Information Modeling (BIM) in the construction industries of China and Australia. The visual, coordination, simulation, and optimization characteristics of BIM provide a foundation for project management. In China, BIM has been widely adopted in major engineering projects, but it still faces challenges such as inactive design institutes, inconsistent data standards, and a shortage of BIM talent. BIM usage in Australia is relatively low, partially due to the lack of government enforcement. It is recommended to promote wider BIM application in various fields through training, resource support, establishing industry standards, and providing incentives. In summary, BIM technology holds significant potential for the future development of the construction industry, but overcoming various challenges is necessary to achieve its maximum benefits.

Research on Construction Safety Management Measures for Building Sites

With the rapid development of China's construction industry, the scale of construction projects is getting bigger and bigger, and the degree of specialization is also increasing. In order to gain a competitive advantage in the market, construction enterprises must focus on construction safety management and optimization of construction processes. In addition, in order to promote the long-term and stable development of the project, project contractors must also focus on the quality, efficiency, and safety of the construction environment in order to protect the lives and properties of workers. Therefore, construction safety management of building projects has become an important element in engineering construction. Comprehensive analysis of construction safety hazards strengthening the construction of safety management systems, improving the safety awareness and skill level of workers, and adopting scientific construction technology and equipment are the important strategies for the current construction safety management of construction projects.

The relationship between social responsibility fulfilment and industry competitiveness: Empirical evidence from construction industry in China.

Social responsibility fulfilment is an important part of the operation management (OM) and competitiveness of the construction industry (CIC). This study investigates the mechanisms through which social responsibility fulfilment in the construction industry affects industry competitiveness and the mediating role of industry operations management. From the intra-organizational stakeholder perspective, social responsibility fulfilment (SR) is divided into two dimensions: shareholder-dimensional (SH) and employee-dimensional social responsibility fulfilment (EM). By analysing a panel of the construction industry in 12 provinces of China from 2015 to 2020, an inverted U-shaped relationship between social responsibility fulfilment and construction industry competitiveness and between shareholder-dimensional social responsibility fulfilment and construction industry competitiveness was found, while a U-shaped relationship between employee-dimensional social responsibility fulfilment and construction industry competitiveness was found. Furthermore, social responsibility fulfilment and shareholder-dimensional social responsibility fulfilment had significant effects on operation management. Additionally, the study concludes that operation management is positively related to construction industry competitiveness and plays a partially mediating role between social responsibility fulfilment and construction industry competitiveness. The findings enrich the theoretical basis of the relationship between social responsibility fulfilment and competitiveness and demonstrates important management significance for the construction industry in managing its social responsibility behaviour and improving industry competitiveness, thus promoting high-quality development of the construction industry.

Countermeasures for the Transformation of Migrant Workers to Industrial Workers in the Construction Industry Based on Evolutionary Game Theory

With the rapid development of new construction methods, China’s construction industry is facing the transformation challenges of industrialization and informationization. However, migrant workers are characterized by high mobility, low education, and poor skills in China’s national conditions, which can no longer meet the requirements of operations. The transformation of the low-level manual migrant workers in the construction industry to high-level skilled industrial workers is inevitable. In order to explore how to better achieve the transformation of construction workers, evolutionary game research with construction unit and labor company as the subjects was carried out. Three types of assumptions were introduced into the constructed evolutionary game model: cooperation mechanism, spillover effect, and incentive mechanism (CSI). Simulation experiments and analysis of the model were finally conducted. The results of the game analysis finally show: (1) a higher initial proportion of selected transformed industrial workers; (2) a fair benefit concession from the construction unit to the labor company; (3) a lower revenue spillover effect; (4) that a higher level of regulation and incentives are conducive to the evolutionary game to converge to the desired state at a faster rate. The findings provide ideas for improving the labor system in China’s construction industry and lay the foundation for solving the labor specialization problem of new construction methods.

Stress Test of Precast Concrete Materials for Prefabricated Buildings by Numerical Analysis

There are serious environmental pollution problems in traditional construction operations. To improve China's construction industry, precast concrete has become one of the important environmental protection materials. Therefore, the stress of precast concrete is deeply analyzed. Based on the numerical analysis, prefabricated concrete buildings and other theories, numerical analysis and finite element method are taken as the research methods to analyze the mechanical properties of precast concrete materials and of steel bars. Finally, the situation and level of the DW1 specimen and DW2 specimen after the influence of the sliding and rotation of the ground beam on the horizontal displacement of the vertex are expounded from various aspects. The research results show that in terms of the mechanical properties of precast concrete materials, the performance data of prefabricated wallboards are all above 37, which is higher than the average strength. In the analysis of mechanical properties of steel bars, the steel bar with a diameter of 8 has a yield strength of 456.4 Mpa, an ultimate strength of 617.3 Mpa, and an elongation of 25.6%. The steel bar with this diameter has the best properties. In DW1 specimen and DW2 specimen, with the continuous progress of the loading process, the overturning moment caused by horizontal loads is also gradually increasing. In the horizontal level of prefabricated building materials, the increase of the axial compression ratio increases the anti-overturning moment of the specimen, and the peak bearing capacity of the specimen increases significantly, but the ductility decreases significantly. In the bearing capacity, there is little difference between the measured bearing capacity and the calculated bearing capacity of each specimen with vertical force applied. Therefore, the force test of precast concrete materials in prefabricated buildings is deeply studied based on numerical analysis, which has an important guiding significance for the construction industry to improve business performance and market competitiveness.

The impact of corporate environmental responsibility on green technology innovation: An empirical analysis of listed companies in China's construction industry

How to enhance competitiveness in the green building market and achieve green sustainable development is a challenge that construction industry enterprises face. To explore the impact and mechanism of corporate environmental responsibility (CER) on green technology innovation (GTI), this article selects data from listed construction companies in the Shanghai and Shenzhen A-share from 2011 to 2020 for empirical analysis. The results show the following: ① Improving the level of CER in the construction industry can promote GTI. ② Financing constraints only mediate the impact of CER on strategic GTI and have no effect on real GTI. ③ The educational background of the executive team positively moderates the promotion of CER on GTI. ④ The ownership nature of state-owned enterprises exhibits a negative moderating effect on CER's influence on strategic GTI, while its moderating effect on real GTI is not significant. ⑤ Media attention positively moderates the promotion effect of CER on strategic GTI, while its promotion effect on real GTI is not significant. After potential endogeneity issues are considered and a series of robustness tests is conducted, these conclusions still hold. The research findings help reveal the relationship between CER and GTI and provide references from the perspective of environmental responsibility for promoting the sustainable development of enterprises.

Transmission of risk to China's construction industry due to international interest rate fluctuations

PurposeUnder the trend of global economic integration and the new context of stagflation, frequent fluctuations in international interest rates are exerting far-reaching impacts on the world economy. In this paper, the transmission mechanism of the impact of fluctuations in international interest rates (specifically, the American interest rate) on the bankruptcy risk in China's pillar industry, the construction industry (which is also sensitive to interest rates), is examined.Design/methodology/approachUsing an improved contingent claims analysis, the bankruptcy risk of enterprises is calculated in this paper. Additionally, an individual fixed-effects model is developed to investigate the mediating effects of international interest rates on the bankruptcy risk in the Chinese construction industry. The heterogeneity of subindustries in the industrial chain and the impact of China's energy consumption structure are also analysed in this paper.FindingsThe findings show that fluctuations in international interest rates, which affect the bankruptcy risk of China's construction industry, are mainly transmitted through two major pathways, namely, commodity price effects and exchange rate effects. In addition, the authors examine the important impact of China's energy consumption structure on risk transmission and assess the transmission and sharing of risks within the industrial chain.Originality/valueFirst, in the research field, the study of international interest rate risk is extended to domestic-oriented industries. Second, in terms of the research content, this paper is focused on China-specific issues, including the significant influence of China's energy consumption structure characteristics and the risk contagion (and risk sharing) as determined by the current development of the Chinese construction industry. Third, in terms of research methods a modified contingent claim analysis approach to bankruptcy risk indicators is adopted for this study, thus overcoming the problems of data frequency, market sentiment and financial data fraud, which are issues that are ignored by most relevant studies.

Decomposition and decoupling analysis of carbon emissions in China's construction industry using the generalized Divisia index method

As the pillar industry of the national economy, the construction industry contributes to economic growth while consuming large amounts of energy and generating carbon emissions. This study adopted the generalized Divisia index method (GDIM) to decompose carbon emissions in the construction industry (CECI) of China and its 30 provinces. A decoupling effort index based on factor decomposition was constructed to analyze the drivers of changes in the CECI and decoupling states during 2000–2020. The results were as follows. (1) The output scale was the main driver for increasing CECI, whereas the carbon intensities of area and output were the largest contributors to decreasing CECI. (2) The national construction industry showed expansive negative decoupling during the 10th–13th FYPs (Five-Year Plans). The decoupling states of provinces showed significant spatial and temporal differences, with most provinces showing negative decoupling and the number of decoupled provinces peaking in the 12th FYP. (3) The scale effect was the key inhibiting factor in the decoupling process of most provinces, while the intensity effect was the main promoting factor, and the efficiency effect was weak. The inhibitory effect of scale gradually weakened, while the promoting effect of intensity increased. Overall, this study expands on current research related to the driving factors of CECI and provides valuable insights into the low-carbon development of the construction industry in other emerging countries.

The integration of BIM in the application of green building materials in construction projects

In recent years, with the growing call for sustainable development, green building materials, which are of great meaning for reducing resource and environmental impacts, have attracted more and more attention. However, in China, a country with frequent construction activities and high resource consumption, the application of green building materials in construction projects still faces challenges. Building Information Modelling (BIM) as an emerging technology in the construction industry can increase the adoption rate of green building materials in construction projects. The aim of this study is to identify the barriers encountered in the application of green building materials in Chinese construction projects, and to propose corresponding improvement measures by integrating BIM in the decision making. This study adapted a qualitative research method, using semi-structured interviews as a research tool. A total of 6 respondents (including project managers, architects, engineers, and researchers) from Chinese construction companies and research institutions collected interview data, and used Nvivo software to analyze and summarize. The results of this study show that although the application of green building materials in construction projects in China still faces challenges, including market acceptance and supply chain issues, cost and economic feasibility issues, and lack of relevant technology and knowledge. In addition, the study found that BIM technology made a great contribution in promoting the application of green building materials. Through BIM technology, the whole life cycle information management such as material selection, engineering simulation and performance evaluation of construction projects can be carried out, so as to improve the application of green building materials. By exploring the obstacles to the application of green building materials in China’s construction projects and combining with the promotion of BIM technology, this study puts forward a series of specific suggestions and solutions to foster the application of green building materials. This research has made certain theoretical and practical contributions to foster the application of green building materials for the sustainable development of China's construction industry.
