Combined effects of toxic Microcystis aeruginosa and high pH on antioxidant responses, immune responses, and apoptosis of the edible freshwater bivalve Corbicula fluminea

Due to increasing anthropogenic perturbation and water eutrophication, cyanobacterial blooms (CYBs) have become a global ecological and environmental problem. Toxic CYBs and elevated pH are considered to be the two key stressors associated with eutrophication in natural waters, particularly in the event of CO2 depletion induced by dense blooms. However, previous research has been focused on investigating the impacts of toxic CYBs or pH changes in isolation, whereas the interactive effects of such stressors on edible bivalves that inhabit CYB waters still lack information. In this study, the combined effects of toxic Microcystis aeruginosa and pH shifts on the antioxidant responses, immune responses, and apoptosis of the edible freshwater bivalve Corbicula fluminea were explored. The results showed that the activity of antioxidant enzymes was significantly impacted by the interactive effects between toxic M. aeruginosa exposure and time course, yet pH shifts showed no significant effects on the activities of these antioxidant enzymes, implying that the antioxidant response in C. fluminea was mainly triggered by toxic M. aeruginosa exposure. Toxic M. aeruginosa also induced an increased production of reactive oxygen species and malondialdehyde in treated clams, particularly under high pH settings. The elevated lysosomal enzyme activity helped C. fluminea defend against toxic M. aeruginosa exposure under high pH conditions. The principal component analysis (PCA) and the integrated biomarker response (IBR) results suggested that the treated clams were subjected to the elevated toxicity of toxic M. aeruginosa in conditions of high pH. The heat shock proteins-related genes might be triggered to resist the oxidative damage in treated clams. Moreover, the upregulation of TNF and casp8 genes indicated the potential activation of the caspase8-mediated apoptotic pathway through TNF receptor interaction, potentially resulting in apoptosis. The TUNEL assay results further confirmed that apoptosis appeared in treated clams. These findings improve our understanding of the combined toxicological effects of harmful algae and pH shifts on bivalves, which will provide insights into a comprehensive ecological risk assessment of toxic CYBs to edible bivalve species.

An integration of physiology, transcriptomics, and proteomics reveals carbon and nitrogen metabolism responses in alfalfa (Medicago sativa L.) exposed to titanium dioxide nanoparticles

Nanoparticle (NP) pollution has negative impacts and is a major global environmental problem. However, the molecular response of alfalfa (Medicago sativa L.) to titanium dioxide nanoparticles (TiO2 NPs) is limited. Herein, the dual effects of TiO2 NPs (0–1000 mg L−1) on carbon (C) and nitrogen (N) metabolisms in alfalfa were investigated. The results showed that 500 mg L−1 TiO2 NPs (Ti-500) had the highest phytotoxicity in the C/N metabolizing enzymes; and it significantly increased total soluble sugar, starch, sucrose, and sucrose‐phosphate synthase. Furthermore, obvious photosynthesis responses were found in alfalfa exposed to Ti-500. By contrast, 100 mg L−1 TiO2 NPs (Ti-100) enhanced N metabolizing enzymes. RNA-seq analyses showed 4265 and 2121 differentially expressed genes (DEGs) in Ti-100 and Ti-500, respectively. A total of 904 and 844 differentially expressed proteins (DEPs) were identified in Ti-100 and Ti-500, respectively. Through the physiological, transcriptional, and proteomic analyses, the DEGs and DEPs related to C/N metabolism, photosynthesis, chlorophyll synthesis, starch and sucrose metabolism, and C fixation in photosynthetic organisms were observed. Overall, TiO2 NPs at low doses improve photosynthesis and C/N regulation, but high doses can cause toxicity. It is valuable for the safe application of NPs in agriculture.

Harmonizing International Environmental Law and National Sovereignty

International environmental law is an important legal tool to deal with the global environmental crisis. In recent years with the increasingly serious and global environmental problems the speed and depth of environmental problems are also increasing. In this process the relationship between state sovereignty and international environmental law and its conflict become the object of study. "To do a systematic analysis this paper attempts to destroy the conflict between national sovereignty and environmental rights and on the basis of in-depth discussion of the background concept formation and development stage of international environmental law to explore whether the two can be coordinated. In particular the concept of "soft standards" is proposed to analyze its actual status and role in international environmental law and its dialectical relationship between legal significance and legal effect in non-binding international instruments. On the basis of respecting national sovereignty the document said that strengthening the supervision of international mechanisms and improving the national responsibility system can promote the effective coordination of international environmental law and safeguard national sovereignty and realize the mutual benefit and win-win situation of environmental protection and national interests. At the same time it puts forward a more cautious attitude towards the criticism and modification of the soft law of the international environment and emphasizes that the universal basis of the law should be paid attention to in the practical application so as to avoid the marginalization of legal research due to excessive dependence on social analysis methods.This paper aims to provide theoretical support and practical guidance for the further development and practical application of international environmental law.

Advanced Development of In situ Characterization Technique for Electrocatalytic Hydrogen Evolution Reaction

AbstractHydrogen evolution reaction (HER) from water splitting using renewable energy provides a promising solution to the global energy crisis and environmental problems. However, the lack of in‐depth understanding of the reaction mechanism and clear identification of the catalytic active site has hindered the further development of low‐cost, high‐performance, and long‐life efficient electrocatalysts. Through in situ characterization techniques, the activity and stability of catalysts can be monitored in real‐time, track the structural evolution of catalytic reaction intermediates, and obtain a deep understanding of catalytic reaction mechanism, so as to feedback and guide the development and utilization of the catalyst. In this review, advanced development of in situ characterization techniques in electrocatalytic HER in recent years is summarized. In situ spectroscopy can be used to track the behavior of reaction intermediates such as adsorption, desorption, and structural evolution at the molecular level to reveal the electrocatalytic HER mechanism. The imaging techniques can be used to observe the evolution of material structure during HER in situ, which provides valuable information for the understanding of visualization of catalytic hydrogen evolution at atomic level. This review contributes to theadvanced development of in situ characterization technique for electrocatalytic HER.

Multifaceted Aquatic Environmental Differences between Nanoplastics and Microplastics: Behavior and Fate.

Microplastics and nanoplastics are emerging pollutants of concern in the aquatic environment that are causing increasing global environmental and human health problems. Although there has been extensive research on microplastics and nanoplastics, little has been said about the differences in their behavior in the aquatic environment, and many studies have considered them as the same class of hazardous materials; but in fact, microplastics and nanoplastics should be considered as two different types of environmentally hazardous materials. In this review, we propose that microplastics and nanoplastics behave in the aquatic environment in a size-dependent manner and should be distinguished. And we systematically analyzed the differences in the behavior of microplastics and nanoplastics in the aquatic environment in terms of five aspects: 1) distribution behavior; 2) adsorption behavior; 3) reaction with natural colloids; 4) aging and leaching behavior; 5) interaction with organisms. This paper has been written to draw academic attention to the different behaviors of microplastics and nanoplastics in the aquatic environment in order to distinguish between their effects on humans and the environment.

HUMANE APPROACH IN TEACHING ENGLISH

At present, the process of integration is rapidly intensifying, states are closely interacting with each other, thus the process of integration in the business and cultural world is taking place. The global problems of all mankind are solved through the unification of nations. These are such problems as the protection of peace and ensuring the stability of each state, the solution of global environmental and economic problems, as well as the development of the country inside and outside its borders. And a tool to solve such problems is a well-established interethnic and intercultural communication. Historically, Kazakhstan has been called a "bridge between East and West" and a "crossroads of civilizations." Kazakhstan is home to representatives of 130 nationalities and 46 religions. Therefore, the ideas of humane pedagogy, based on eternal universal values, are embedded in the national consciousness of Kazakhstanis. As the great Abai said: "Love all people as brothers." Therefore, it is necessary to study the world and national heritage of humane pedagogy and introduce the spiritual and moral ideas of humanism into the theory and practice of the modern pedagogical space of Kazakhstan. [1]. This article examines the main possibilities of applying a humane approach to the study of foreign languages in secondary schools and presents the results of a study to identify ways to humanize educational activities.

Association of sudden sensorineural hearing loss with meteorological factors: a time series study in Hefei, China, and a literature review

Air pollution can cause disease and has become a major global environmental problem. It is currently believed that air pollution may be related to the progression of SSNHL. As a rapidly developing city in recent years, Hefei has serious air pollution. In order to explore the correlation between meteorological variables and SSNHL admissions, we conducted this study. This study investigated the short-term associations between SSNHL patients admitted to the hospital and Hefei climatic variables. The daily data on SSNHL-related hospital admissions and meteorological variables containing mean temperature (T-mean; °C), diurnal temperature range (DTR; °C), atmospheric pressure (AP; Hp), and relative humidity (RH; %), from 2014 to 2021 (2558 days), were collected. A time-series analysis integrating distributed lag non-linear models and generalized linear models was used. PubMed, Embase, Cochrane Library, and Web of Science databases were searched. Literature published up to August 2023 was reviewed to explore the potential impact mechanisms of meteorological factors on SSNHL. The mechanisms were determined in detail, focusing on wind speed, air pressure, temperature, humidity, and air pollutants. Using a median of 50.00% as a baseline, the effect of exceedingly low T-mean in the single-day hysteresis effect model began at a lag of 8 days (RR = 1.032, 95% CI: 1.001 ~ 1.064). High DTR affected the admission rate for SSNHL on lag 0 day. The significance of the effect was the greatest on that day (RR = 1.054, 95% CI: 1.007 ~ 1.104) and then gradually decreased. High and exceedingly high RH affected the admission rate SSNHL on lag 0 day, and these effects lasted for 8 and 7 days, respectively. There were significant associations between all grades of AP and SSNHL. This is the first study to assess the effect of meteorological variables on SSNHL-related admissions in China using a time-series approach. Long-term exposures to high DTR, RH values, low T-mean values, and all AP grades enhance the incidence of SSNHL in residents. Limiting exposure to extremes of ambient temperature and humidity may reduce the number of SSNHL-related hospital visits in the region. It is advisable to maintain a suitable living environment temperature and avoid extreme temperature fluctuations and high humidity. During periods of high air pollution, it is recommended to stay indoors and refrain from outdoor exercise.

The Potential Capabilities of two species of Azolla as a Bioaccumulator in Summer

Now a days, worldwide excessive use of chemical fertilizer, can have many undesirable effects on human health and the environment, which can be reduced or eliminated by adopting new agricultural practices such as use of organic inputs, namely manure, biofertilizer. On the other hand, water eutrophication has been a challenging global environmental problem recently. Plants can be grown in eutrophicated water, and after consumption from eutrophicated water, the harvested biomass of this plant can play important role as a useful green manure, rich in N P K. The use of Azolla, a N fixing water-fern can be a novel idea in this regard. Azolla spp. have a unique capability to accumulate more P, K within its body than its requirement and can be considered as NPK tablets. So, the experiment was conducted in order to find out the efficient species with regard to high biomass production with high accumulation of P, K, and tolerating higher concentration of media-P in summer. Light intensity and concentrations of media-P have a remarkable influence on the productivity and NPK accumulation of the species. Open area was more favorable than the partial shade for biomass production. Both the species have the capability to tolerate 60 ppm of media-P and produce their maximum biomass at only 15 ppm of media-P. A. filiculoides was found to produce more biomass, accumulate more tissue-P, contain more or less the same amount of N, and less K when compared with A. pinnata. Thus, in hot climate, A. filiculoides can be considered better accumulator of Phosphorus and A.pinnata can be considered better accumulator of Potassium being an effective scavenger of P, K.

Energy Consumption at Accommodation Buildings: A Case Study of a Boutique Hotel-Abdera

Global environmental problems such as decreasing biodiversity, natural disasters, climate change, and energy consumption are among the main concerns of the countries. Approximately 50% of the energy consumed worldwide is spent on architectural construction, use, and operation. The increase in energy consumption in buildings especially has taken the reduction of carbon footprint and the importance of energy efficiency to the fore. Physical environment, climate, orientation, envelope, and material properties are among the different factors in determining energy consumption in buildings. The share of tourism activities in total emissions is estimated to be 5%. However, it is also stated that tourism buildings have a share of 21 % of C02 emissions. This work aimed to research the energy consumption of a boutique hotel in Abdera, Greece. ArchiCAD, Graphisoft, and EcoDesigner software were used in the analysis of findings, and suggestions were put forward. Energy consumption and environmental effects were investigated when active solar systems (Solar Thermal Panel /STP (30 m2), Photovoltaic Panel/PV (30 m2)) were added to the roof surface (total 60 m2 Panel) of the building. The analysis showed that the addition of active solar systems by 30% could reduce emissions. In Greece, which is located in a very favorable region in terms of geographical features, it is very important to use solar potential with integrated systems in buildings to provide energy needs.

Reducing the fatal attraction of nocturnal insects using tailored and shielded road lights

The attraction of insects to artificial light is a global environmental problem with far-reaching implications for ecosystems. Since light pollution is rarely integrated into conservation approaches, effective mitigation strategies towards environmentally friendly lighting that drastically reduce insect attraction are urgently needed. Here, we tested novel luminaires in two experiments (i) at a controlled experimental field site and (ii) on streets within three municipalities. The luminaires are individually tailored to only emit light onto the target area and to reduce spill light. In addition, a customized shielding renders the light source nearly invisible beyond the lit area. We show that these novel luminaires significantly reduce the attraction effect on flying insects compared to different conventional luminaires with the same illuminance on the ground. This underlines the huge potential of spatially optimized lighting to help to bend the curve of global insect decline without compromising human safety aspects. A customized light distribution should therefore be part of sustainable future lighting concepts, most relevant in the vicinity of protected areas.

Improve energy use efficiency through free trade policy: evidence from the establishment of free trade zones in China.

In the context of increasing global resource and environmental problems, it is of great practical significance to accurately test the impact of various factors on energy use efficiency for maintaining national energy security and formulating relevant policies. This paper measures firms' total factor energy efficiency (TFEE) using the two-stage stochastic frontier method within the data envelopment analysis (DEA) framework, leveraging data from listed firms in China spanning 2010 to 2022. Employing the establishment of free trade zones (FTZs) as a quasi-natural experiment, we apply the staggered differences-in-differences (DID) and stacked DID methods and analyze the impact of FTZs on firms' TFEE. The results show that the establishment of FTZs significantly promotes the improvement of firms' TFEE, and it has a greater promotion effect on heavily polluting, non-manufacturing, state-owned, private, and small-scale firms. The results of the mechanistic analysis showed that the promotion effect of FTZs on firms' TFEE is mainly realized through three channels: increasing government subsidies, reducing the financing constraint effect, and encouraging the technology innovation effect. Furthermore, industry-level decomposition results indicate that the surge in industry energy efficiency primarily results from improvements within firms rather than inter-industry variations. This paper's results propose that countries can enhance energy efficiency by progressively endorsing the implementation of FTZs.

Li/La and Cu modified ZnO semiconductor: Highly boosted of dielectric and sunlight-treatment of thiamethoxam and brilliant green contaminants

Solving the global environmental problem which related to the dissolved organic pollutants into water systems is an essential issue for human-health and aquatic life. This study represents the simple synthesis of new Li/La and Cu modified ZnO compositions as active photocatalysts and proper dielectric materials for electrical energy storage devices. The synthesized powders have one phase nature with hexagonal lattice indexed to ZnO structure. The field emission scanning electron microscopy (FESEM) clearly showed that (Li, La) modified ZnO powder consist of a mixture of particles having open hexagonal tube and spherical shapes. The FESEM picture of (Li, Cu, La) modified ZnO powder revealed lumps like cabbage shape mainly composed of pieces like sheets or papers. The purity and elemental composition were also verified by energy dispersive spectroscopy (EDS) analysis. The addition of (Li, La) and (Li, Cu, La) ions to ZnO semiconductor extremely improved the dielectric constant which is a benefit for application in solid state energy storage systems. (Li, Cu, La) modified ZnO sample is a suitable catalyst for removal of organic waste owing to its high response to visible light spectrum with measured band gap energy of 2.76 eV. The synergistic effect of Li+, Cu2+ and La3+ dopants induced high visible light photodegradation activities against thiamethoxam pesticide and brilliant green dye with measured efficiencies of 92 and 96 % after reaction time of 50 min, respectively. The high stability and mineralization properties of (Li, Cu, La) modified ZnO catalyst leads to the conclusion that this composition has a potential use in wastewater treatment.

China's future energy vision: Multi-scenario simulation based on energy consumption structure under dual carbon targets

In the face of global environmental problems, China has advanced a “dual-carbon" target, and the proportion of non-fossil energy consumption will be more than 25 % in 2030 and more than 80 % in 2060. Considering this goal as the starting point, this study applies the system dynamics method and combines different types of sectors and energy consumption structures to model China's energy consumption system. Through multi-scenario simulations of different energy consumption structures, the study finds that: (1) the growth rate of energy consumption and energy consumption structure are the main factors affecting carbon emissions; (2) industrial carbon emissions follow the changes in total carbon emissions, and the industry is the most important and challenging sector for solving the problem of carbon emissions; (3) under the premise of optimizing the energy consumption structure, China can achieve peak carbon in 2030, and to achieve carbon neutrality in 2060; (4) under the inertia of social development and energy structure, the energy demand of the tertiary sector is expanding, and natural gas is an unquestionable choice for China as a transitional energy source.

Integration of [Cr3O(HCOO)6(H2O)3]NO3 into MIL-101(Cr) for enhanced separation of CO2/N2 mixture

Developing novel adsorbents for CO2 capture and separation offers an efficient approach to relieving global environmental problems. To promote CO2 capture from flue gas, novel Cr3O@MIL-101(Cr) composites was synthesized through packing [Cr3O(HCOO)6(H2O)3]NO3 into MIL-101(Cr) cages. The resultant composite Cr3O@MIL-101(Cr) presents higher CO2 uptakes at lower pressure ranges, benefiting from the increased content of unsaturated Cr(III) ions and micropores relative to MIL-101(Cr). Meanwhile, IAST selectivity for CO2/N2 mixture reached 50.2 under standard temperature and pressure, outperforming most of the reported materials. Further GCMC simulations reveal that the synergistic effect of [Cr3O(HCOO)6(H2O)3]+, NO3− and MIL-101 (Cr) could effectively facilitate the interactions with CO2 molecules and hinder N2 molecules from approaching the optimal adsorption sites. Thus the [Cr3O(HCOO)6(H2O)3]NO3 encapsulated MIL-101(Cr) can be recommended as a promising adsorbent for superior CO2/N2 separation.

The Carbon Footprint and Its Impact on Sustainable Accounting An Exploratory Study of the Opinions of A Sample Of Employees At Al-Joud Company

Energy is the backbone of modern life and the lifeline of many sectors. In contrast, it is the leading cause of climate change. The magnitude of this problem, considered one of the global environmental problems that have become a concern for all of humanity, has prompted people to search for ways to reduce these emissions and then protect the environment and achieve accountability. Sustainability can be measured through a set of indicators, including the environmental footprint, which was used initially, and the carbon footprint, which relates to carbon emissions only. This is what we will highlight in this research paper as we try to understand the carbon footprint concept and its impact on sustainable accounting.

The roles of rare and abundant microbial species in the primary succession of biological soil crusts are differentiated in metal tailings ponds with different states

Tailings ponds formed by long-term accumulation of mineral processing waste have become a global environmental problem. Even worse, tailings ponds are often simply abandoned or landfilled after they cease to be used. This allows pollution to persist and continue to spread in the environment. The significance of primary succession mediated by biological soil crusts for tailings pond remediation has been illustrated by previous studies. However, the process of primary succession may not be the same at different stages during the lifetime of tailings ponds. Therefore, we investigated the environmental differences and the successional characteristics of microbial communities in the primary successional stage of tailings ponds at three different states. The results showed that the primary succession process positively changed the environment of tailings ponds in any state of tailings ponds. The primary successional stage determined the environmental quality more than the state of the tailings pond. In the recently abandoned tailings ponds, abundant species were more subjected to heavy metal stress, while rare species were mainly limited by nutrient content. We found that as the succession progressed, rare species gradually acquired their own community space and became more responsive to environmental stresses. Rare species played an important role in microbial keystone species groups.

Physiological response and molecular mechanism of Quercus variabilis under cadmium stress

Heavy metal pollution is a global environmental problem, and Quercus variabilis has a stronger tolerance to Cd stress than do other species. We aimed to explore the physiological response and molecular mechanisms of Q. variabilis to Cd stress. In this study, the antioxidant enzyme activities of leaves were determined, while the photosynthetic parameters of leaves were measured using Handy PEA, and ion fluxes and DEGs in the roots were investigated using noninvasive microtest technology (NMT) and RNA sequencing techniques, respectively. Cd stress at different concentrations and for different durations affected the uptake patterns of Cd2+ and H+ by Q. variabilis and affected the photosynthetic efficiency of leaves. Moreover, there was a positive relationship between antioxidant enzyme (CAT and POD) activity and Cd concentration. Transcriptome analysis revealed that many genes, including genes related to the cell wall, glutathione metabolism, ion uptake and transport, were significantly upregulated in response to cadmium stress in Q. variabilis roots. WGCNA showed that these DEGs could be divided into eight modules. The turquoise and blue modules exhibited the strongest correlations, and the most significantly enriched pathways were the phytohormone signaling pathway and the phenylpropanoid biosynthesis pathway, respectively. These findings suggest that Q. variabilis can bolster plant tolerance by modulating signal transduction and increasing the synthesis of compounds, such as lignin, under Cd stress. In summary, Q. variabilis can adapt to Cd stress by increasing the activity of antioxidant enzymes, and regulating the fluxes of Cd2+ and H+ ions and the expression of Cd stress-related genes.

Marketization Mechanism of Environmental Protection Law under Global Governance

The Global Environmental Problem is becoming serious, which needs to maintain the environmental governance mechanism effectively. This study analyzes the marketization mechanism of environmental protection law under global governance to meet the environmental challenge. Analyzing the severe background of environmental problems, highlighting the urgency of global governance in environmental protection, it explores the main content of the market-oriented mechanism of environmental protection law. Using various research methods such as literature analogy and clause research, this topic is elaborated from different perspectives. The market-oriented mechanism of environmental protection laws helps to stimulate the environmental awareness of enterprises and individuals, promote the effective utilization of resources and sustainable development of the environment. Attention should be paid to exploring areas such as improving market supervision, strengthening international cooperation, and promoting technological innovation, in order to provide reference for a better global environmental governance mechanism.

The Cd resistant mechanism of Proteus mirabilis Ch8 through immobilizing and detoxifying

Cadmium (Cd) pollution is a serious global environmental problem, which requires a global concern and practical solutions. Microbial remediation has received widespread attention owing to advantages, such as environmental friendliness and soil amelioration. However, Cd toxicity also severely deteriorates the remediation performance of functional microorganisms. Analyzing the mechanism of bacterial resistance to Cd stress will be beneficial for the application of Cd remediation. In this study, the bacteria strain, up to 1400 mg/L Cd resistance, was employed and identified as Proteus mirabilis Ch8 (Ch8) through whole genome sequence analyses. The results indicated that the multiple pathways of immobilizing and detoxifying Cd maintained the growth of Ch8 under Cd stress, which also possessed high Cd extracellular adsorption. Firstly, the changes in surface morphology and functional groups of Ch8 cells were observed under different Cd conditions through SEM-EDS and FTIR analyses. Under 100 mg/L Cd, Ch8 cells exhibited aggregation and less flagella; the Cd biosorption of Ch8 was predominately by secreting exopolysaccharides (EPS) and no significant change of functional groups. Under 500 mg/L Cd, Ch8 were present irregular polymers on the cell surface, some cells with wrapping around; the Cd biosorption capacity exhibited outstanding effects (38.80 mg/g), which was mainly immobilizing Cd by secreting and interacting with EPS. Then, Ch8 also significantly enhanced the antioxidant enzyme activity and the antioxidant substance content under different Cd conditions. The activities of SOD and CAT, GSH content of Ch8 under 500 mg/L Cd were significantly increased by 245.47%, 179.52%, and 241.81%, compared to normal condition. Additionally, Ch8 significantly induced the expression of Acr A and Tol C (the resistance-nodulation-division (RND) efflux pump), and some antioxidant genes (SodB, SodC, and Tpx) to reduce Cd damage. In particular, the markedly higher expression levels of SodB under Cd stress. The mechanism of Ch8 lays a foundation for its application in solving soil remediation.

Research on the Relationship between GSCM and Enterprise Performance: a Multidimensional Analysis based on Manufacturing Industry

Green supply chain management (GSCM) refers to focusing on green environmental protection and reducing the pollution of the whole industrial chain in the process of enterprise production and cooperation with upstream and downstream, which helps to realize the coordinated development of the economy and the environment. With the increasing global environmental problems, GSCM has become an inevitable trend for the transformation and upgrading of manufacturing enterprises in China. However, the relationship between GSCM and enterprise performance has not yet reached a consensus. This paper adopted a multi-case study research method to analyze the GSCM performance of manufacturing enterprises from multiple dimensions. The results showed that GSCM enhances enterprise performance by improving economic, environmental and social performance. These performance improvements not only contribute to the long-term development of the enterprise, but also enhance the competitiveness of the enterprise and the sustainability of its development. This study would improve and enrich the theory of GSCM, and enhance the theoretical basis for enterprises to improve their competitiveness and realize sustainable development. At the same time, the study can provide reference for the government and relevant organizations to formulate and implement relevant policies, and provide important theoretical guidance and decision-making reference for realizing the high-quality development of China's economy.
