While existing literature acknowledges the development of digital capabilities as essential for enterprises to achieve digital transformation, it falls short in offering comprehensive theoretical insights into the dynamic evolution of these capabilities, especially in the field of environmental and sustainability issues. This paper addresses this gap by employing an exploratory single-case study methodology to investigate the intricate process through which an ecological restoration enterprise in China updates its digital strategy, facilitating the dynamic evolution of its digital capabilities from a resource orchestration theory perspective. Our findings reveal a sequential evolution from digital strategy renewal to resource orchestration and, ultimately, the advancement of digital capabilities. Specifically, the enterprise engages in a co-adjustment and co-creation process, aligning its resources with a digital strategy refresh and fostering the emergence of digital integration and innovation capabilities through effective resource management. This includes the accumulation and divesting of resources as part of the construction process, alongside the enrichment and bundling of resources. This research bridges the gap in the current literature by providing a nuanced understanding of the mechanisms that drive the evolution of digital capabilities, and it offers a theoretical framework that integrates strategic renewal with resource orchestration for environmental and socio-economic sustainable development. Furthermore, the insights gained provide vital managerial implications for the governance, corporate social responsibility and policy of industrial digitalization towards global environmental practice and sustainable development goals (SDGs).

Rational assessment of the regional sustainable development level is an important prerequisite for formulating development strategies and achieving the UN Sustainable Development Goals (SDGs). Currently, little literature provides nuanced understanding for national sustainable development from the perspective of county sustainability. Such studies can provide more accurate regional heterogeneity characteristics and policy decision support. Thus, this paper applies the entropy weight method and Chinese county data from 2000 to 2017 to reassess the sustainability of Chinese counties. The results show that China's county sustainability (Sustainable Development Index, SDI) is slowly improving. County sustainability performance is poorer in ethnic minority agglomerations, poor counties, old revolutionary counties, and central and western regions, better in county-level cities and eastern regions. The decomposition results show that economic sustainability and environmental sustainability are the main supporters of SDI growth, and livelihood sustainability is in urgent need of improvement. The regional inequality of SDI in Chinese counties gradually decreases, and inter-group differences are the main contributors to regional inequality in SDI. This paper provides support for China to develop county-level sustainable development measures and practice the SDGs. The findings could be useful for policymakers. [Display omitted] • Based on the entropy weight method and the Chinese county data, the sustainable development levels of 1533 counties in China from 2000 to 2017 are estimated. • Analyses of spatial-temporal dynamic heterogeneity, Linear decomposition, and Dagum decomposition are conducted to study the features of sustainable development in Chinese counties. •The influence of natural features and national concern preferences on county sustainable development are discussed.

As the path of industrial eco-efficiency (IEE) needs to be re-examined from a multi-dimensional perspective, this research opens the internal "black box" of China's industrial eco-economic system driven by sustainable development goals (SDGs) and decomposes IEE into industrial production and sustainable development stages. It further divides the industrial production stage into two parallel subsystems of water use efficiency (WUE) and energy efficiency (EE) and derives SDG6 efficiency (SDG 6 E) and SDG7 efficiency (SDG 7 E) in the sustainable development stage respectively. The paper proposes a meta two-stage parallel entropy dynamic DDF-DEA model to re-measure IEE of 30 provinces in China from 2015 to 2021, discusses the relationship between overall efficiency and stage efficiency, and by using the Tobit model explores various types of influencing factors by subregion. The results show that the modified DDF-DEA model can explore China's IEE more accurately under SDGs. China's IEE is more stable from 2015 to 2021, with the efficiency value always fluctuating between 0.59 and 0.64, the overall level is low, and there is more room for improvement. There are significant inter-provincial differences in IEE and efficiency inertia. In more than 75% of the provinces SDG 7 E constrains IEE improvement, while the dynamic evolution of IEE and its subsystem efficiency varies across regions. Environmental regulation is a common factor affecting IEE across the country and in the east, central, and west regions, whereas the level of economic development, openness to the outside world, and urbanization rate are differential factors affecting IEE across the country and in the three major regions. This study offers new perspectives for exploring the path of IEE enhancement and providing empirical references for the collaborative construction of industrial ecological civilization.

Shale gas plays an important role in energy transformation. The sustainable development of the shale gas industry is a prerequisite for achieving an efficient, green, and long-term use of shale gas resources. This paper uses the WSR (Wuli-Shili-Renli) methodology to determine a comprehensive indicator system for assessing the sustainability of the shale gas industry. Game theory was used to combine two objective weighting methods and determine the comprehensive weight. The sustainability of the shale gas industry was evaluated based on the fuzzy matter-element extension theory. The results of the evaluation show that the overall sustainable development of China's shale gas industry is relatively poor. Shale gas industry in most regions is in a critically sustainable state (The critically sustainable state indicates the sustainability of the shale gas industry in general. The industry as a whole has the basic conditions for sustainable development in the short term; however, efficiency needs to be further improved to avoid the risk of degradation.) and is susceptible to degradation due to environmental changes. The shale gas industry in a few other regions is in an unsustainable state and cannot achieve an efficient and green development of shale gas. This paper evaluated the sustainability of the shale gas industry from a unique perspective. It is expected that the results of this research will contribute to the formulation of sustainable development strategies and further promote the green development of the shale gas industry. • The sustainability of the shale gas industry in some areas of China was studied. • We developed an evaluation model using the WSR methodology and the fuzzy matter-element extension method. • Expanded the application scope of game theory methods. • China's shale gas industry has a poor level of sustainable development.

China's rapid urbanization growth during the past decades which has highly promoted its affluence has induced various challenges for the countryside. The problem of rural decline of quite many villages which are suffering depopulation in turn challenges the urbanization sustainability in China. By way of in-depth historical and literature review, the paper finds distorted urban-rural relationship and the tendency of village decline owing to China's long time urban biased policy. By further investigating China's new-type urbanization strategy, the paper draws concerns about future rural development which is less mentioned in the plan. It calls for ruralization and actions to revitalize the countryside so as to be adapted to China's new-type urbanization plan. [ABSTRACT FROM AUTHOR]

Abstract The sustainability of the water-energy-food (WEF) nexus is a significant challenge faced by developing countries, especially China. Evaluating the sustainability status of China's water-energy-food, and improving its sustainable use, may provide good physical conditions to support China's future development. This paper applied the Pressure, State, and Response (PSR) model to select evaluation indexes. A combination weighting method was used to combine two objective weighting methods to determine index weights. The study constructed the classical field, the limited field, and the matter-element to be evaluated. This allowed the establishment of an improved matter-element extension model to evaluate the sustainability of the water-energy-food nexus; the model was then used to quantitatively evaluate the sustainability of China's water-energy-food nexus. The simulation results indicated that in 2005, the sustainability of China's water-energy-food was at a relatively low efficiency rank. By 2015, the sustainability of China's water-energy-food had reached a general efficiency rank. The results suggested that the sustainability of China's water-energy-food system significantly improved between 2005 and 2015; however, the improved sustainability remained at a general status (The general status means that the sustainability of water-energy-food nexus in China can meet the basic development needs, but it is far from the optimal state and needs further adjustment and improvement). Thus, China should improve its current utilization patterns for the three resources and consider them as a whole. This would help realize synergistic resource use and enhance their sustainability. Highlights • The sustainability of WEF nexus is a severe challenge faced by developing country. • An improved matter-element extension model to evaluate sustainability of WEF nexus. • The sustainability of China's WEF system significantly improved from 2005 to 2015. • China should improve its utilization patterns for the WEF and consider it as whole.

The huge energy consumption and high pollutants emission have restrained the sustainable development of China's iron and steel industry. It is very necessary to explore those underlying obstacles which hinder the sustainable development of this industry from a systematic point. This paper adopted an improved emergy based method and a set of indicator system to evaluate the sustainability of steel production enterprises, in which dilution method, disability adjusted life years (DALY) method and potentially disappeared fraction (PDF) method were integrated into classic emergy analysis to quantify the impact of emissions, and then the related indicator system characterizing the industrial production process was put forward. One steel production enterprise in Sichuan Province, China, as a case, was studied using the proposed methods and indicator system. The research results show that this enterprise is not sustainable in the long term, due to large share of nonrenewable inputs and strong dependence on imported inputs; emissions' impact further aggravates this situation due to the increasing environmental loading; the proposed methods and indicator system can act as one of helpful tools for decision-making in steel & iron industry. Finally, this paper gives some corresponding suggestions so as to improve the comprehensive performance of this enterprise. [ABSTRACT FROM AUTHOR]

The increasing pressures of global warming, population growth and epidemic occurrence are causing challenges in meeting the growing requirements for water, energy and food. In particular, the contradiction between the supply and demand for water, food, and energy is exacerbated by inefficient resource utilization and carbon emission increase. Incorporation of the interlinked aspects of water, energy, food and carbon emissions from agricultural systems into one water-food-energy-carbon nexus facilitates integrated resource management. Biochar application to farmland is a potential strategy for carbon management and agricultural productivity improvement. The integration of biochar systems and the water-food-energy-carbon nexus is an efficient and coordinated alternative method for sustainable agricultural management and a crucial strategy for addressing water, energy and food security issues. Accordingly, this paper proposes an approach for the synergistic regulation of water, land, energy, and carbon emissions in a circular agricultural system by balancing water supply and demand, land allocation, electricity consumption, and economic upgrading principles. A two-stage circular agriculture framework is constructed, with biochar and electricity generated from agricultural residues at the first stage and employed at the second stage. Economic-environmental-energy harmonization is considered in the methodology, and the agrotechnical potential of biochar is quantified via crop yield increase and greenhouse gas emission reduction functions. This approach can assist decision makers in providing the best policy options given certain agricultural resources to achieve the maximum economic performance of the system while minimizing environmental side effects. In this paper, the model framework is applied to the Sanjiang Plain in northeastern China to verify the feasibility of the approach. The results indicate that the external electricity demand is reduced by 87.8% due to the generation of biofuels. Cropland greenhouse gas emissions are reduced by 34.09%–67.06% via the application of biochar. This study proposes an optimization method with important implications for the improvement of regional cropland management techniques and development of sustainable circular agriculture. This methodology can be extended to other agriculture-centered regions with limited resources and environmental problems. • Carbon cycle is integrated in agricultural water-food-energy-carbon (AWFEC) nexus. • An AWFEC nexus based model is developed for agricultural resources recycling. • Biochar and electricity are optimized sustainably for circular agriculture. • Analysis of resources recycling on economic-environmental balance is performed.

Bicycles are a desirable form of transportation for many reasons, including the fact that taking a bicycle is environmentally-friendly, economically cost-effective, a way to keep fit and healthy and, on occasions, an enjoyable social activity. This paper explores the characteristics and commonalities between particular bike-sharing systems in urban areas, with a view to deriving influences on the sustainability of such systems. The empirical study is China and the paper analyses bike-sharing systems in five Chinese cities. China is suffering from the severe negative consequences of high private vehicle usage in large and densely populated cities. Nevertheless a long history of bicycle usage in the country provides great potential for such a green form of travel to be part of public and private transportation. The findings show that bike-sharing systems have varying degrees of success. The configurations which seem the most sustainable consider and integrate elements relating to transport planning, system design and choice of business model. Key conclusions are that those responsible for developing policy and practices in relation to bike-sharing systems need to understand the diverse aspects of value for the stakeholders wishing to engage with such a system. Public bicycle sharing, as a Product Service System, needs to be carefully developed to appreciate the quality and timely interplay between the physical design of the system and the provision of services being offered.

Construction industries have significant impacts on the economy, society and environment. To transform construction industry towards sustainability, construction enterprises' perceptions and performance on sustainability needs to be understood and evaluated, which has not be fully explored by existing studies. This paper holistically examines the Chinese construction enterprises’ attitude towards and performance on various aspects of sustainability (e.g. the economic, social and environmental aspects) in order to identify those aspects the firms perceive to be the most and least important and those aspects the firms perform best and worst on. The associations among the sustainability attitude, sustainability performance, and firm size are also explored. The findings show that quality management and customer service are perceived as the most important as well as the best-performed aspects by the firms while supporting community development is the least important and worst-performed aspect. Sustainability attitude is positively correlated with performance, and larger firms tend to have better sustainability performance than that of small ones. However, larger construction firms do not necessarily perceive sustainability more important. This study provides a useful reference for policy makers and researchers to understand how sustainability is perceived and implemented by the Chinese construction firms. [ABSTRACT FROM AUTHOR]

Fresh food cold supply chains (CSCs) feature high fresh food quality and safety, high energy consumption, and poor economic and environmental sustainability. Sustainable management of fresh food CSCs is critical. However, limited research has addressed the implementation of systematic good practices in sustainable fresh food CSCs in developing countries. Consequently, decision-makers lack empirical evidence to help them understand how companies successfully implement systematic good practices and how those good practices affect sustainability performance. This paper formulates a hybrid analytic hierarchy process-fuzzy technique for order preference by similarity to ideal solution (AHP-Fuzzy TOPSIS) decision framework to systematically explore the impact of good practices on the sustainability performance of fresh food CSCs in the context of a developing country such as China. The results of the integrated methodology show that China's CSC industry pays more attention to economic sustainability and that employee training is the most impactful good practice for improving the sustainability performance of fresh food CSCs. • A systematic study of good practice and sustainability performance indicators. • A fresh food CSC sustainability performance assessment framework applied in China. • Order of importance of sustainability performance assessment indicators. • Ranking of good practices to improve fresh food CSC sustainability performance.

Small and medium-sized enterprises (SMEs) play a very important role in national production, and provide more than 60% of the employment opportunities for the society. The benign development of small and medium-sized enterprises determines the sustainability of economic operation. In recent years, small and medium-sized enterprises have faced increasing operational pressure. Due to scale limitations, insufficient funds and weak bargaining power, small and medium-sized enterprises are often at a disadvantage when dealing with suppliers. One the one hand, large suppliers rely on the imbalance of bargaining power to increase the transaction costs of small and medium-sized enterprises; On the other hand, small and medium-sized suppliers with poor reputation may use legal loopholes to commit fraud, which may even threaten the survival of small and medium-sized enterprises in severe cases. However, the existing literature focuses more on the situation of large organizations facing complex and diverse suppliers. Therefore, this paper constructed a supplier selection evaluation framework for small and medium-sized enterprises, and proposed an extended PROMETHEE Ⅱ method to achieve sustainable supplier selection process. First, establish a sustainable supplier selection evaluation framework from the three dimensions of product and service capability, cooperation degree and risk factors; Second, combine the PROMETHEE Ⅱ approach with subjective preference parameters and probability language term set (PLTS) to obtain an extended PROMETHEE Ⅱ approach; Last, use the methodology of this paper to implement sustainable supplier selection for a small and medium-sized enterprise (M company) in China. The practical case and sensitivity analysis showed that the evaluation framework and method proposed in this paper were applicable and effective. Actual cases and sensitivity analysis showed that cost, credit and corporate irregularities were the three most important aspects for small and medium-sized enterprises to evaluate supplier performance. [Display omitted] • Small and medium-sized enterprises face complex and diverse suppliers. • Establish a sustainable supplier selection criteria framework. • Improve the PROMETHEE Ⅱ method by combining probabilistic language term sets. • The study provides decision support for the supplier selection.

China is experiencing rapid development and suffering from resource depletion and increasing environmental emissions. It is necessary to identify the key patterns of resource use in different Chinese regions so that more appropriate solutions can be raised. Under such a circumstance, the aim of this paper is to scientifically measure and evaluate the sustainability of natural resources utilization of 30 Chinese provinces for the year of 2007 by adopting a bio-perspective method-emergy analysis. After referring to the traditional emergy accounting method, several emergy-based indicators were established to evaluate resource flows, structure, efficiency and the overall sustainable level of different Chinese regions. Furthermore, by employing GIS technology, spatial distribution of natural resources was presented to illustrate emergy consumption with various regional characteristics in 30 Chinese provinces, which may help better understand regional disparities of resource utilization. The results show that regions with most emergy consumption include Shanxi (2.07E+24sej) and Shandong (2.07E+24sej), and most regions with higher resource consumption locate in east China, while less developed region Qinghai has the highest sustainability level, with ESI being 44.82. Another key finding is that renewable resources were very important to sustainability development, and a large amount of consumption on non-renewable resources led to higher environmental press on local and surrounding ecosystems. Sustainable resource use can only be achieved by reducing total resource use, encouraging technology innovation, initiating institutional reform and preparing region-specific development strategies.

Industrial parks have been adopted as one way to promote industrial development in China since the early 1980s. However, most of current performance evaluation indicators highlight the maximization of industrial yield, leading to both ecological degradation and environmental pollution due to intensive industrial activities. Therefore, it is critical to develop appropriate evaluation indicators so that industrial parks can move toward sustainable development. This paper aims to fill such a research gap by developing innovative emergy indicators. Kaya formula and index decomposition analysis (IDA) were integrated together in order to quantify the key factors influencing the sustainability of an industrial park. Tianjin Economic Development area (TEDA), the largest industrial park in terms of its economic scale in China, was chosen as one case study area for testing the related methods. The results show that during the period of 2006–2010 the sustainability of TEDA experienced a declining trend. From the Kaya formula and IDA analysis, indicators on economic efficiency of process, economic return on investment, renewable empower density and nonrenewable empower density were calculated. Such research findings provide valuable policy insights to the industrial park managers so that they can prepare appropriate development strategies for achieving sustainable development of their industrial parks by considering the local realities.

Sustainability is a key issue should be considered in the process of urbanization construction. The sustainable development of cities plays an important role in increasing urbanization quality. The paper evaluated the sustainability level of 19 first-tier cities in China by selecting 18 indicators from economic, social and environmental systems. Since indicator is the basic unit of the measurement of urban sustainability, the sustainability was refined to the indicator level. Indicator sustainability was measured by the combination of its competitive and developing levels. In addition, a sustainability oriented sequential relationship analysis method was proposed to allocate more weight to the indicator with higher sustainable level. The assessment results indicate that the sustainable performances of the cities were not ideal, because only three cities, Beijing, Shenzhen, and Dongguan, had the average performances above 0.5. Besides Tianjin, all the cities showed an upward development trend in the year 2010–2018. It indicates the sustainability prospect of these cities is optimistic. It is found that economy had the strongest connection with cities' sustainability. However, most of the cities showed the worst performance on economic sustainability. Combining the phenomenon of environmental decline in some cities, it is suggested to strengthen environmental protection while giving priority to economic development so as to realize the coordinated development between economy and environment. Image 1 • This paper evaluated the sustainability of 19 first-tier cities in China. • A SO-SRA method was proposed where weight reflects indicator sustainability. • Cites' sustainability was not ideal, only 3 cities with performances above 0.5. • Nearly all cities (accounting for 94.7%) showed an optimistic development prospect. • More than half cities showed the poorest sustainability on the key factor, economy.

Water, energy, and food (WEF) are pivotal resources for the sustainable development of human society. Integrated assessment of the sustainable WEF nexus is essential to enhance resource efficiency and security, but there is a crucial gap to be filled in assessing the coupling relationship among sustainable WEF subsystems and improving multi-sectoral synergy. In this paper, a comprehensive indicator system for sustainable WEF nexus assessment was constructed based on theme-based frameworks and nexus thinking, and the combination weighting method based on game theory (GT-CW), the improved TOPSIS method based on gray relation degree (GRD-ITOPSIS), and the coupling coordination model were proposed for integrated assessment. The sustainability of WEF nexus in 30 regions of China from 2010 to 2019 was assessed and the spatiotemporal differences of the coupling coordination degree of sustainable WEF nexus were analyzed. The results revealed that the sustainability of WEF subsystems evidently affected the overall sustainability of regional WEF nexus. The change range of sustainable WEF nexus in different years was slightly lower than that of a single subsystem. The sustainability of WEF subsystems were highly coupled, and the WEF nexus in each region was within the coordinated development range. However, most eastern regions were at the intermediate coordinated development stage, and some western regions maintained at primary coordinated development stage for a long time. According to the results analysis, specific policy recommendations were proposed. The findings of this study can provide a useful reference for developing countries to improve resource management and promote sustainable development.

Low-carbon production is key to both economic and environmental sustainability. It is, however, inadequate to meet the low-carbon targets by the manufacturing industry alone. Current research on emission reduction targets mainly at individual optimality, with little consideration of the synergistic benefits achievable through coordination among supply chain players. This paper fills this gap by incorporating Pareto improvement to ensure that all members are likely to gain in emission reduction through coordination. It gives the emission-dependent manufacturers theoretical basis and managerial insights to go through the stringent emission-limited market, especially under a new proposed low-carbon policy of flexible cap-and-trade, which will soon be deployed for emissions trading in China. This flexible cap-and-trade policy aligns emission reduction with capacity adjustments, but its impact has rarely been investigated. Considering the complexity of the supply chain structure, this paper simplifies the problem to two stages: manufacturer and retailer. While the demand uncertainty is considered with Newsvendor models, Stackelberg game is exploited to solve this problem with three contracts, namely revenue sharing, cost sharing, and two-part tariff. Analytical and numerical studies show that the profitability and greenness of the supply chain are increased by coordination with revenue sharing and two-part tariff contracts. The Pareto improvement encourages cooperation between the supply chain members. Managerial insights are given to help emission-dependent manufacturers compete in the increasingly stringent low-carbon environment. The novelty of this paper lies in the investigation of synergistic benefits achievable through coordination under the new flexible cap-and-trade emission policy, and the Pareto-improving conditions with several contracts are analyzed by Newsvendor models. • Synergistic benefits achievable through different contracts are discussed. • It first analyzes the supply chain coordination problem under flexible cap-and-trade. • Green awareness and demand uncertainty are considered. • It targets to improve profitability and sustainability under emission restrictions. • TPT and RSC can coordinate the supply chain, but CSC cannot.

Abstract: China has now the largest annual outputs of galvanized steel and the most amount of galvanizing plants in the world. However, with obsolete technology, the hot dip galvanizing industry has been proved as one of the industries, which consume large amounts of raw materials and energy, produce numerous pollutants and causes serious contamination in China. Cleaner Production in the hot dip galvanizing industry is now the only way to achieve the sustainable development of hot dip galvanizing industry. The implementation of the Common Fund for Commodities (CFC) project: The Transfer of Technology and Promotion of demand: Batch hot dip galvanizing in China launched by International Zinc Association (IZA) is introduced in this paper, The Best Available Technologies of operation, energy and environmental management in the world are also introduced. With the implementation of the project, an assessment system of Cleaner Production and a training system have been developed and implementation of technical updating to the demonstration plant shows that the reduction of zinc loss, and water and fuel cost savings can be achieved. It is believed that the methodology of the project can be applied throughout China as the galvanizers see the cost benefits. [Copyright &y& Elsevier]

The results show that its sustainability is very low and declining in this period, emissions obviously reduce the sustainability although their impacts are generally decreasing, and the main reasons lie in its low nonrenewable resources and energies'' efficiencies. Finally, the related suggestions were put forward for improving its comprehensive performance. [Copyright &y& Elsevier]

Sustainability is related to support the huge population and improve the residents' well-being in the Mega-city regions. Sustainability assessment is necessary under the context of implementing the Sustainable Development Goals in 2030. Refer to SDG 11, this study constructed an index system, assessed the sustainability level based on the theory of "weak" and "strong" sustainability and screened obstacles of 26 cities in the Yangtze River Delta (YRD) by applying a combined method of GIS–entropy–TOPSIS. The results showed that the overall sustainable level of the YRD improved, while its spatial pattern is relatively stable from 2007 to 2016. Furthermore, the co-operation effect within regions was unstable and unbalanced, due to the lack of interaction and influence among cities. In addition, the obstacles of each city gradually shifted from strong sustainable factors to weak sustainable factors. This paper also provided corresponding solutions regarding government management practice. • The overall sustainability level of the YRD improved obviously during 2007–2016. • The spatial correlation of sustainability among cities was weak and unstable. • The sustainability of megacities was more affected by weak sustainability factors.
