Evolution and Influencing Factors of Spatial Correlation Network of Construction Carbon Emission in China from the Perspective of Whole Life Cycle

Based on the whole life cycle perspective, the carbon emissions of the provincial construction industry in China from 2011 to 2019 were calculated from the production, construction, operation, and demolition stages of building materials. A spatial correlation network matrix of the carbon emissions in the construction industry was constructed by using the modified gravity model, and the structural characteristics of the correlation network were described by introducing social network analysis. Through the quadratic assignment program, the spatial correlation matrix of carbon emissions in the construction industry and its influencing factors were regressed and analyzed. The conclusions were as follows:① the spatial correlation network of carbon emissions in China's construction industry clearly existed. The network density and network correlation numbers were gradually rising, and the network tightness and stability were gradually improving. ② Shanghai, Tianjin, Beijing, and Jiangsu had a higher degree centrality and closeness centrality, which are the core and dominant positions of the spatial correlation network of carbon emissions in the construction industry. Zhejiang replaced Shanghai in the top four from 2013 to 2018, and the betweenness centrality of each province had unbalanced characteristics. ③ Beijing, Tianjin, Jiangsu, Inner Mongolia, Shanghai, and Shandong were "net beneficiaries" blocks, receiving the carbon emissions from other regions. Four provinces, Guangdong, Chongqing, Fujian, and Shandong, belonged to the "broker" sector, achieving a dynamic balance between the production and consumption sides of building carbon emissions. The remaining 20 provinces played a "net spillovers" role, actively sending carbon emissions from the construction industry to other provinces. The correlation between blocks was much greater than the correlation relationship within the blocks. ④ Industrial structure, urban population, spatial adjacency, consumption level, and construction industry process structure had a significant influence on the spatial correlation of carbon emissions in the construction industry. The greater the inter-provincial differences in industrial structure, urban population, spatial adjacency, and consumption level, the greater the similarity of inter-provincial construction industry process structure, and the stronger the spatial correlation and spatial spillover of the construction industry carbon emissions. Finally, according to the evolution characteristics and influencing factors of the spatial correlation network of building carbon emissions, relevant countermeasures and suggestions were provided for the collaborative carbon reduction development of the construction industry region.

The Impact of Mergers and Acquisitions on the Internationalisation Level of Enterprises--The Case of Sany Group

As the cornerstone of China's engineering construction, the construction machinery industry plays an important role in the process of foreign trade and export. This fully reflects the important demand for China's construction machinery industry, but also shows the important position of the industry in the international market. At present, China's construction machinery market is open to the outside world, the domestic and foreign construction machinery market competition is fierce, many scholars on China's construction machinery export trade situation and ways to improve the enterprise's global market share to do in-depth research. In this paper, we find that Sany Heavy Industry is ranked in the top of the global construction machinery manufacturers, brand, scale, technology than other domestic construction machinery enterprises have advantages, from the perspective of Sany Heavy Industry through cross-border mergers and acquisitions to improve the level of internationalisation, through a combination of quantitative and qualitative methods, to provide assistance to the international development of China's small and medium-sized construction machinery enterprises.

Spatial differences, dynamic evolution and influencing factors of China's construction industry carbon emission efficiency

Improving the construction industry carbon emission efficiency (CICEE) is crucial for achieving sustainable development. To promote low-carbon development in the construction industry, it is essential to measure carbon emission efficiency (CEE) and analyze spatial differences, dynamic evolution, and influencing factors. This study measures CICEE in 30 provinces in China from 2005 to 2019 and evaluates CEE using the minimum distance to a strong efficient frontier (MinDS) model with undesirable outputs. Subsequently, the Dagum Gini coefficient and its decomposition, as well as spatial autocorrelation analysis, are used to explore the sources of spatial differences and the spatial clustering pattern of CEE. The dynamic trend of CEE is analyzed through kernel density estimation, traditional and spatial Markov chains. Finally, geographical detectors are used to detect the explanatory factors and their interactions on spatial differences in CEE. The results of this study show that the CICEE presents an increasing and then decreasing trend, with the highest CEE in the eastern region, followed by the central and northeastern regions, and the lowest in the western region. Additionally, the eastern region exhibits the highest intra-regional differences and the highest inter-regional differences with the western region. Meanwhile, CEE shows a positive spatial correlation, with high-high (H-H) clustering in the eastern region and low-low (L-L) clustering in the western and northeastern regions. Polarization has been evident throughout the entire country and its four regions in recent years. It is challenging to achieve the CEE transfer through rapid advancement, and the efficiency of neighboring provinces will influence the potential transfer of the local province. Finally, factors such as enterprise scale, economic development level, degree of openness to the outside world, innovation level, industrial structure, and energy consumption structure all affect the spatial differences in CEE, with the interaction effect being higher than the single factor. This study presents a novel computational model to measure CICEE, analyzes the structural factors contributing to the spatial differences in CICEE, and provides theoretical support for the synergistic improvement of CEE across different regions. Combining with spatial autocorrelation analysis, the spatial distribution characteristics of CICEE are analyzed from the static level. This study provides a comprehensive examination of the evolution trend of CICEE, focusing on its dynamic evolution characteristics and the long-term transfer dimension. Additionally, geographical detector technology is introduced for the first time to analyze the influencing factors of spatial differences in CICEE. providing scientific evidence for the sustainable and coordinated development of different regions in China's construction industry. Furthermore, this study also contributes to the development of varied strategies for improving CICEE in China.

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.

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.

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 practices of nature-based solutions in China

Nature-based Solutions (NbS) is a concept aims to address challenges related to human well-being, including human health, socio-economic development, and ecological security on both national and global scales. This concept was proposed against the backdrop of global climate change, ecological crises affecting humanity, and threats to sustainable development and it has been increasingly recognized and applied internationally over the past decade. The principle of NbS is reciprocity between humans and ecosystems, which is completely in line with the goals, systems, practices, and concepts guiding China's construction of ecological civilization. This paper clarifies concepts, evaluation criteria, and comprehensive benefits related to NbS, to trace the connection between NbS and both traditional and contemporary ecological civilization principles in China. By drawing valuable experience from NbS practices in China, it will focus on proposing policy and implementation suggestions to address challenges currently faced in NbS applications in China. This research will promote the research and practice of nature-based solutions in China. Meanwhile, provide novel perspectives and technologies for urban ecological design as well as sustainable development.

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.

Exploration of safety management problems and countermeasures in the construction of housing projects

In the field of modern construction, quality and safety have always been the most important concern of construction units, and the quality and safety of housing construction projects also have a certain link, through the quality and safety management of housing construction projects, not only can improve the market competitiveness of construction enterprises, but also an important means to obtain high profits. Therefore, building construction enterprises must actively improve construction safety management, understand the potential safety risks of each link, improve the safety management level of housing projects, and promote the long-term development of China's construction enterprises.

Multiple regression analysis was employed to investigate the influence of intellectual capital, its components and digital transformation on the performance of construction firms.FindingsThe study's results reveal that the performance of construction firms greatly depends on intellectual capital and its components. Furthermore, digital transformation plays a vital moderating role between intellectual capital and its components and construction firm performance.Practical implicationsThis study addresses a critical inquiry on how construction managers can employ intellectual capital to enhance the performance of firms during digital transformation. Additionally, this research bridges this gap by guiding construction managers to concentrate on their external surroundings when examining firm performance.Originality/valueBy focusing on the predictors influencing construction firms' performance, this study contributes to the existing corpus of knowledge. This study employs resource orchestration theory (ROT) to determine how the different components of intellectual capital impact the performance of construction firms, with digital transformation acting as a moderating variable. This research will be valuable to researchers, construction industry professionals and policymakers.

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.

Carbon emissions marginal abatement cost and its influencing factors from the construction and hygienic ceramics manufacturing industries in China

Reducing China's carbon dioxide (CO2) emissions primarily involves efforts from energy-intensive sectors, including the construction and hygienic ceramics manufacturing industries. Although the majority of extant studies have focused on estimating marginal abatement cost (MAC) of CO2 emissions, there are mainly four shortcomings: (i) most of studies have explored this issue at industrial level or provincial level, the evidence at the enterprise level is limited; ii) the selection of emissions abatement measures and strategies is normally arbitrary; iii) the characteristics of MAC changing with the amount of emissions reduction is usually ignored; and iv) the analysis of influencing factors for MACs is not included. Here, this study provided an innovative MAC estimation for China's 913 construction ceramics enterprises and 360 hygienic ceramic enterprises. A quadratic directional distance function method, including multiple emissions abatement measures and all possible directional vectors representing different emission reduction strategies, is applied to calculate the lowest MAC. We further incorporate the abatement level from 1 to 99% into MACs estimation, and investigated its influencing factors. The results mainly illustrated three relevant findings. (i) The average MAC for construction ceramics manufacturing is 2203 CNY/t CO2, which is lower than that for hygienic ceramics manufacturing of about 8416 CNY/t CO2. (ii) Construction ceramics production enterprises would be willing to downscale production to achieve the lowest cost for emissions reduction, whereas hygienic ceramics production enterprises tend to choose increasing the intermediate input. (iii) Energy use efficiency positively influences MACs for both construction and hygienic ceramics production enterprises, while intermediate input rate, energy consumption structure (the proportion of fuel coal consumption in total energy) and profitability are negatively related to MAC. Results and findings can provide references for the formulation of carbon emission reduction policies in China's construction and hygienic ceramics manufacturing industries.

Total-factor CO2 performance in China's construction sector: Spatiotemporal trend, driver and future pathway

China actively participates in global efforts to mitigate CO2 emissions, with a particular emphasis on the crucial role of the construction sector in achieving these objectives. This research endeavor commences by conducting an in-depth analysis of the maximum potential for reducing carbon intensity (CI) within China's construction sector from 2005 to 2019. The assessment is executed through the utilization of a non-radial directional function, with the total-factor CO2 emission performance index (TCPI) serving as the principal metric. Subsequently, this study employs network analysis, an extended decomposition technique, and scenario analysis to comprehensively investigate the evolving network trends, key determinants influencing TCPI, and potential pathways for further CI reduction. The findings of this investigation reveal the following critical insights: 1) The overall trajectory of TCPI exhibits an upward trend, characterized by dynamic shifts in its hierarchical structure over the specified time frame. 2) Several influential factors contribute positively to the observed TCPI increase, including investment-based energy intensity (the largest contributor), the potential carbon factor, technical efficiency in economic development, and carbon productivity. Conversely, the investment-output share exerts a negative influence on TCPI. 3) An alarming prospect emerges as the construction sectors in Tianjin, Heilongjiang, Anhui, Jiangxi, Henan, and Guizhou face potential challenges in achieving the 2030 targets, which aim for a 60%–65% reduction in CI compared to 2005 levels under a business-as-usual scenario. Consequently, a concerted effort to reduce carbon emission factors and energy intensity becomes imperative. This study underscores the critical need for the formulation and implementation of enhanced CI reduction policies within the construction sector, emphasizing the vital role of government intervention in achieving these objectives.

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.
