The coordination and optimization of eco-tourism development and world heritage protection are related to the sustainable development of the two,and the behavior of tea farmers is affected by the multiple subjects of rural production and living system,which has nonlinear and complex characteristics.In view of this,based on the theory of human-land system,this study is using system theory and fuzzy set qualitative comparative analysis(fsQCA)to explore the internal mechanism of tea farmers‘environmental responsibility behavior.The results show that:(1)single factor,infrastructure environment perception constitutes a necessary condition for environmental responsibility behavior,and there is equivalence between infrastructure environment perception,Cultural environment perception,external intervention perception and environmental supervision perception.(2)Infrastructure environment perception and cultural environment perception are important internal driving forces for high environmental responsibility behavior,while external intervention perception and environmental supervision perception constitute external traction.(3)Infrastructure environment perception and cultural environment perception exist in all configurations in a single or common form.This provides enlightenment for changing the governance logic of ecotourism and improving the governance performance of ecotourism. 展开更多

Pollution discharge permit system is the permit system for controlling pollutant discharge, and it is the basic environmental management system for regulating the pollutant discharge behavior of enterprises and institutions according to law. The competent department of ecological environment issues and supervises the pollutant discharge permit. The full implementation of the pollution discharge permit system is a pioneering work of the party and the country to deepen the ecological environment protection work under the new situation. Reasonable implementation of the pollution discharge permit system is conducive to the effective supervision and management of enterprises' pollution discharge by the competent department of ecological environment, as well as the improvement of the awareness of ecological environment protection by the pollutant discharge units, the establishment of a refined self-discipline mechanism and the initiative to assume the main responsibility of ecological environment protection for pollutant emission control. Furthermore, it enables enterprises to effectively unify ecological environment protection and economic development, promote green and low-carbon circular development, and achieve the goal of energy conservation and emission reduction in China. 展开更多

This paper develops an economic growth model incorporating China’s Environmental Target Responsibility System(ETRS)to analyze its impact on both economic growth and social welfare.We find that the ETRS’s effect on economic growth is complex,resulting from the interplay of three key factors:its potential to improve environmental quality,its potential dampening effect on total factor productivity(TFP),and its influence on local government spending on environmental governance.A balanced ETRS can improve environmental quality,promote technological innovation,and enhance social welfare.However,excessively stringent targets and overly emphasized responsibility may lead to declines in both economic growth and social welfare.From the perspective of balancing economic growth and social welfare,we find that the ETRS that maximizes economic growth is less stringent than the ETRS that maximizes social welfare.Crucially,the economic growth cost of shifting from a growth-maximizing to a welfare-maximizing ETRS is minimal.In other words,significant improvements in environmental quality and public well-being can be achieved without substantially sacrificing economic dynamism.This paper attempts to model China’s unique environmental target assessment system within the framework of endogenous growth theory,offering a new perspective for understanding the dynamic relationship between economic growth and environmental quality in China. 展开更多

Community-based ecotourism (CBET) aims to empower local communities through engagement and participation. Cambodia serves as a prime example of a developing country where the local community necessitates sustained stakeholder support to foster empowerment and promote local economic development. Ecotourism and conservation are among the major issues of concern in the study of community development. This study used the main five eco-tourism areas in Cambodia as examples. It looks at the connections between eco-innovations in tourism products, community engagement, co-creation experiences, support for CBET, perceived impact likelihood outcomes, community economic benefits, environmentally responsible behavior in ecotourism sites, and biodiversity conservation. The study employed a quantitative research approach to investigate and parameterize the dynamic ecotourism components as well as to explore key factors that influence the CBET. We collected the data using a self-administered survey on 398 local eco-based tourism communities that sell services and products to tourists. We also asked for structured questionnaire items of local communities that provide tourism services to visitors in eco-tourism destination sites in 2022-2023. The SEM results showed that this study significantly impacted and confirmed all relationships among research variables, as proposed in the conceptual model. We also discuss in detail the research findings of this study. 展开更多

Corporate environmental sustainability has become a critical concern,particularly in resource-intensive industries such as pharmaceuticals,where regulatory pressures and stakeholder expectations continue to rise.Despite increasing attention to green leadership,limited research has explored how environmentally responsible leadership(ERL)influences corporate environmental performance(CEP)through employee-driven sustainability behaviors.This study addresses this gap by examining the mediating roles of green knowledge-sharing behavior(GKSB),green innovative behavior(GIB),and voluntary green behavior(VGB),as well as the moderating role of green shared vision(GSV)in the ERL-CEP relationship.The study is grounded in Resource-Based View(RBV),Knowledge-Based View(KBV),Environmental-Based View(EBV),and Triple Bottom Line(TBL)theories,which collectively explain how leadership-driven sustainability efforts create long-term competitive advantages,drive environmental responsibility,and balance economic,social,and environmental sustainability.A quantitative research design was employed,using survey data from 384 employees in Bangladesh’s pharmaceutical sector.Data were analyzed using Partial Least Squares Structural Equation Modeling(PLS-SEM)in Smart-PLS 4.0 to assess direct,indirect,and moderating effects.The results confirm that ERL has a significant positive impact on CEP,with GKSB,GIB,and VGB acting as mediators,while GSV strengthens the ERL-CEP relationship.This study provides novel empirical evidence on the mechanisms linking green leadership to corporate sustainability,extending the application of RBV,KBV,EBV,and TBL to leadership-driven environmental management.The findings emphasize the importance of leadership training programs,sustainability-focused organizational cultures,and shared environmental visions.Policymakers should consider incentives for companies adopting ERL practices,ensuring that sustainability becomes a strategic,rather than compliance-driven,priority.This study contributes to leadership and sustainability literature by offering a comprehensive framework for integrating ERL into corporate governance and environmental strategies. 展开更多

In China corporate social and environmental responsibility(CSER)has gained increasing attention within industry and government.Evidence exists for significant attempts to promote CSER by the Chinese government.As a critical‘pillar’industrial sector,urban residential apartment development has been a major contributor to China’s national gross domestic product.This industry has also profoundly influenced social and environmental issues in the country.Thus,apartment developers in China have felt increased pressures to implement CSER practices.Little research has sought to investigate CSER in this industry,whether in China or globally.The objective of this paper is to empirically investigate,using a surveyed sample of 92 apartment development companies,CSER practices in this industrial sector.In the empirical analysis we find that CSER practices can be grouped into basic,environmentally-related and extended practices.We further compare these groupings of CSER practices among different sizes of apartment developers using multivariate analysis of variance and Scheffe multiple analysis tests.We also apply one-way analysis of variance and t-tests for comparisons of CSER practices among apartment developers from differentcities and with different ownership structures.The results show that apartmentdevelopers generally implement environmentally-related and extended CSER practicesat higher levels.Residential apartment development is occurring in more developedcities,and thus apartment developers in these cities face more pressures for CSERpractices.Joint ventures are more likely to implement environmentally-related CSERpractices.Research and managerial implications,and future research directions are alsopresented in this work. 展开更多

This study evaluates the Fuzzy Analytical Hierarchy Process(FAHP)as a multi-criteria decision(MCD)support tool for selecting appropriate additive manufacturing(AM)techniques that align with cleaner production and environmental sustainability.The FAHP model was validated using an example of the production of aircraft components(specifically fuselage)employing AM technologies such as Wire Arc Additive Manufacturing(WAAM),laser powder bed fusion(L-PBF),Binder Jetting(BJ),Selective Laser Sintering(SLS),and Laser Metal Deposition(LMD).The selection criteria prioritized eco-friendly manufacturing considerations,including the quality and properties of the final product(e.g.,surface finish,high strength,and corrosion resistance),service and functional requirements,weight reduction for improved energy efficiency(lightweight structures),and environmental responsibility.Sustainability metrics,such as cost-effectiveness,material efficiency,waste minimization,and environmental impact,are central to the evaluation process.A computer-aided modeling approach was also used to simulate the performance of aluminum(AA7075 T6),steel(304),and titanium alloy(Ti6Al4V)for fuselage development.The results demonstrate that MCD approaches such as FAHP can effectively guide the selection of AM technologies that meet functional and technical requirements while minimizing environmental degradation footprints.Furthermore,the aluminumalloy outperformed the other materials investigated in the simulation with the lowest stress concentration and least deformation.This study contributes to advancing cleaner production practices by providing a decision-making framework for sustainable and eco-friendly manufacturing,enabling manufacturers to adopt AM technologies that promote environmental responsibility and sustainable development,while maintaining product quality and performance. 展开更多

Since the implementation of the reform and opening-up policy,China has undergone a period of rapid development.However,this urban expansion has been accompanied by significant ecological challenges.Therefore,understanding the relationship between urban expansion and ecological sustainability is crucial for future urban planning.This study analyzes land use data to investigate the spatiotemporal dynamics of urban agglomeration expansion from 2000 to 2020.Using MODIS satellite data,this study constructs a Remote Sensing Ecological Index(RSEI)model to assess ecological quality changes over the past two decades.Additionally,an improved coupling coordination model is applied to examine the interaction between urban expansion and ecological quality and to evaluate the spatiotemporal trends of their coordination.The results indicate that:①From 2000 to 2020,urban expansion in the Henan section of the Yellow River Basin followed a pattern of“growth-growthdecline”.Pattern recognition analysis indicated that both urban agglomerations and individual cities primarily expanded through edge extension and infill development,while enclave-style expansion occurred in only a small portion of the region.②Between 2000 and 2020,the ecological quality of urban agglomerations in the Henan section of the Yellow River Basin showed a slight improvement.RSEI values ranged from 0.4 to 0.7,indicating moderate ecological quality.Ecological quality exhibited a spatial pattern of being higher in the southwest and lower in the northeast.Significant declines in ecological quality were primarily concentrated in urban built-up areas,forming a patch-like distribution.Conversely,notable improvements in ecological quality occurred mainly in the mountainous regions of the southwest and north.③Between 2000 and 2020,the coupling coordination level of urban agglomerations showed an increasing trend.Coupling coordination values ranged from 0.248 to 0.734.Most cities were near an imbalance between urban expansion and ecological quality,while Zhengzhou was the only city to consistently maintain coordinated development over two decades.Spatially,highly imbalanced areas were mainly concentrated in the western and southern Henan sections,particularly in Sanmenxia and Luoyang.Conversely,areas with high coupling coordination were centered around Zhengzhou,showing a radial expansion pattern in recent years. 展开更多

The biased allocation of emission reduction target constraints quantifies emission reduction responsibilities and reflects differences in pollutant reductions both across and within cities.This approach represents a systematic innovation aims to enhance China’s green competitiveness and facilitate its economic transformation through localized and precise policymaking.Using panel data from 275 Chinese cities spanning 2000-2022,this study applies the difference-in-differences method to estimate the impact of biased allocation of emission reduction target constraints on urban green competitiveness.The findings indicate that such constraints-whether based on chemical oxygen demand or sulfur dioxide targets-significantly improve urban green competitiveness,with both pollutant-specific constraints producing comparable effects.Furthermore,these constraints exhibit significant spatial spillover effects within a 200-km geographical radius.Heterogeneity analysis reveals stronger policy impacts in resource-based cities,eastern regions,and cities designated as key areas for pollution prevention and control.Mechanism analysis demonstrates that the constraints enhance green competitiveness primarily by fostering green technological innovation and optimizing industrial structures.These conclusions provide a practical foundation for addressing China’s enduring conflict between environmental protection and economic development. 展开更多

In high plants, the LHC gene family constituting the light-harvesting complex ofphotosystems I and II. the transfer of solar energy using light-harvesting chlorophyll includes LHCA and LHCB sub-families, which encode proteins Zostera marina L. is a monocotyledonous angiosperm and inhab- its submerged marine environments rather than land environments. We characterized the Lhca and Lhcb gene families of Z. marina from the expressed sequence tags (EST) database. In total, 13 unigenes were annotated as ZmLhc, 6 in Lhca family and 7 in ZmLhcb family. ZmLHCA and ZmLHCB contained the conservative LHC motifs and amino acid residues binding chlorophyll. The average similarity among mature ZmLHCA and ZmLHCB was 48.91% and 48.66%, respectively, which indicated a high degree of diver- gence within ZmLHChc gene family. The reconstructed phylogenetic tree showed that the tree topology and phylogenetic relation- ship were similar to those reported in other high plants, suggesting that the Lhc genes were highly conservative and the classification of ZmLhc genes was consistent with the evolutionary position of Z. marina. Real-time reverse transcription (RT) PCR analysis showed that different members of ZmLhca and ZmLhcb responded to a stress in different expression patterns. Salinity, temperature, light intensity and light quality may affect the expression of most ZmLhca and ZmLhcb genes. Inorganic carbon concentration and acidity had no obvious effect on ZmLhca and ZmLhcb gene expression, except for ZmLhca6. 展开更多

This paper focused on tourists' environmental responsible behaviors in the context of all-for-one tourism. On the basis of clarifying the connotation, dimension and driving factors of tourists' environmental responsible behaviors, this paper firstly analyzed the relationship between all-for-one tourism and tourists' environmental responsible behaviors, and proposed that the development of all-for-one tourism was an important path to optimize and upgrade China's tourism industry and a new concept of sustainable development of tourism industry. The emergence of all-for-one tourism has formed a new tourism trend, which will drive tourists to behave more civilly. Tourists' environmental responsible behaviors are a "subject and share" concept, and from tourists' point of view, all-for-one tourism development is the most basic requirement. Secondly, based on the theory of "value-belief-norm", this paper focused on the strengthening mechanism of "interaction effect" between all-for-one tourism and tourists' environmental responsible behaviors, and put forward the idea of "double internalization strengthening" to guide tourists' environmental responsible behaviors from being passive to active, from individuals to groups. Finally, this paper discussed the promotion of environmental responsible behaviors of tourist's specific strategies from two aspects, "external drive" and "internal drive" to enhance the level of all-for-one tourism construction and strengthen the environment responsibility of tourists. "External drives" were as follows:(1) to make a scientific development plan to implement the "host and vip sharing" mechanism;(2) to optimize the landscape, the environment, services, enhance the local attachment of visitors;(3) to improve the infrastructure system, pay attention to the details of visitors' experience;(4) to strengthen environment education and publicity, deepening the quality of tourists' civilization construction, and strengthen the environmental responsible behaviors of tourists. "Internal drives" were as follows:(1) to strengthen the sense of environmental responsibility of tourists;(2) to establish a model of environmental responsible behaviors;(3) to strengthen the supervision of environmental responsible behaviors. 展开更多
