    本研究探讨了自然资源租金,工业附加值,银行业发展,可再生能源消费,1995年至2019年金砖国家动态背景下的总储量和环境质量。金砖国家经济体应对全球温室气体排放负责,并面临紧迫的环境挑战。包括生物多样性的丧失和污染。对于因变量,环境质量,该研究使用PCA为所有环境指标构建了一个综合指数,其中变量之间的相互依赖性普遍存在。除此之外,该研究结合了两个相互作用的术语,以确定自然资源租金和银行业发展通过工业增值的中介作用对环境质量的间接影响。通过应用CS-ARDL技术,研究结果表明,自然资源租金,工业附加值,总储备对ENQ有积极影响,表明工业部门对环境质量的不利影响以及由于资源密集型工业生产而导致的持续环境退化,强调可持续资源管理的紧迫性。相比之下,银行业发展和可再生能源消费对ENQ产生负面影响,标志着发达银行业在支持生态友好型项目和提高环境质量方面的积极作用。这项研究为政策干预提供了宝贵的见解,以促进更可持续的未来。
    This study explores the association between natural resources rent, industrial value addition, banking development, renewable energy consumption, total reserves and environmental quality in the dynamic context of BRICS nations from 1995 to 2019. BRICS economies are responsible for global greenhouse gas emissions and confront pressing environmental challenges, including biodiversity loss and pollution. For the dependent variable, the environmental quality, the study constructed a composite index using PCA for all environmental indicators where interdependencies among variables are prevalent. Besides this, the study incorporates two interaction terms to determine the indirect influence of natural resource rent and banking development on environmental quality through the mediating role of industrial value addition. By applying the CS-ARDL technique, the outcomes of the study reveal that natural resources rent, industrial value addition, and total reserves positively influence ENQ, indicating the adverse consequences of industrial sectors on environmental quality and continued environmental degradation due to resource-intensive industrial production, underscoring the urgency of sustainable resource management. In contrast, banking development and renewable energy consumption negatively influence ENQ, signifying the positive role of developed banking sectors in supporting eco-friendly projects and enhancing environmental quality. This study offers valuable insights for policy interventions to foster a more sustainable future.

    本研究考察了全球价值链整合之间的动态关系,和碳排放,从2000年到2018年,57个发展中经济体。我们的结果表明,GVC参与与碳排放之间存在多部分联系。具体来说,前瞻性参与,这涉及外国出口中的国内内容,提供了减少排放的潜力,而落后的参与,由国内出口中的外国含量定义,通常会增加排放。这种不平衡引起人们对矿产资源利用的双重性质的重视,根据全球价值链的参与程度,这可能有助于和减轻环境损害。研究中采用的NARDL模型还揭示了碳排放对GVC内矿产资源利用变化的动态和非线性响应。我们的研究结果表明,全球价值链中矿产资源使用的积极冲击会对碳排放产生负面影响,而不利的冲击影响较小。研究结果具有重大的政策意义,这表明发展中国家在规划全球价值链参与时应该优先考虑环境可持续性。这需要促进增值采矿资源使用计划,并推动全球价值链中严格的环境法规。我们的结果还强调了实施定制措施以减轻经济活动对环境质量的不对称和非线性影响的重要性。它启发发展中国家的决策者在日益相互联系的全球经济中平衡环境保护和经济增长。
    This study examines the dynamic relationship between global value chain integration, and carbon emissions, in 57 developing economies from 2000 to 2018. Our results show a multipart link between GVC involvement and carbon emissions. Specifically, forward participation, which involves domestic content in foreign exports, offers the potential to reduce emissions, whereas backward participation, defined by foreign content in domestic exports, typically increases emissions. This imbalance draws attention to the dual nature of using mineral resources, which can contribute to and mitigate environmental damage depending on the extent of GVC engagement. The NARDL model employed in the study also reveals the dynamic and nonlinear responses of carbon emissions to variations in the utilization of mineral resources within GVCs. Our findings show that positive shocks to mineral resources use within GVCs negatively influence carbon emissions, while adverse shocks have less impact. The results have significant policy implications, indicating that developing nations should prioritize environmental sustainability while planning their GVC participation. This entails promoting value-added mining resource use initiatives and pushing for strict environmental regulations in GVCs. Our results also highlight the significance of implementing customized measures to mitigate economic activity\'s asymmetric and nonlinear impacts on environmental quality. It enlightens policymakers in developing nations on balancing environmental conservation and economic growth in a global economy that is becoming more interconnected.

    As an innovative financial instrument, green credit is a new driving force for environmental governance. To study the impact of green credit on environmental quality, this paper uses the provincial panel data from 2007 to 2020 to construct a panel model for analysis based on the comprehensive environmental quality index. At the same time, it discusses the mechanism and regional heterogeneity of green credit affecting environmental quality. The results show that green credit significantly improves the overall quality of the environment, which has a significant effect on air quality and green quality but has no significant impact on water quality and soil quality. Green credit improves environmental quality by improving green technology innovation and promoting industrial structure upgrading. At the same time, there is obvious heterogeneity in the environmental effect of green credit. Among them, the environmental quality improvement effect of the eastern region and the carbon emission pilot area is more evident than that of the central and western regions and the non-carbon emission pilot area. This paper has important implications for promoting the development of green credit and giving full play to the environmental effects of green credit to achieve sustainable goals.

    碳排放对气候变化有负面影响。在过去的几十年中,环境质量面临着巨大的挑战。生态环境质量有助于评估生态环境状况,以支持人类的文明和发展。通过使用排放栅格数据集,遥感图像,和LULC数据,这项研究探讨了碳排放(CE)的现状,生态环境质量(RSEIC),以及萨马林达都市区两个变量之间的动态关系,印度尼西亚。本研究使用时空方法来加深对2000-2021年CE-RSEIC的理解。方法包括CE分析和RSEIC的主成分分析。要了解CE-RSEIC的空间特征,采用方向分布椭圆法。此外,这项研究进行CE-RSEIC耦合分析,并确定其LULC型组成。研究结果表明,CE状况仍处于上升趋势,集中在东部地区,并在此期间不断扩大。低发射椭圆的位置在西南部,而高排放椭圆在东部,与核心城市相交。平均RSEIC值在0.2878和0.4223之间,这表明生态环境质量被归类为相当差到较差。绿色,湿度,和Csink对RSEIC有积极影响。极差类椭圆位于内陆地区,非常好的椭圆在沿海地区。CE-RSEIC耦合状态表明,大部分区域的耦合度较弱。然而,耦合度较高的集中在人口中心和建成区,这是定居区。在较高耦合度下,沉降区的优势组成表明,沉降区对CE-RSEIC耦合度的提高有影响。所以,沿海大都市地区的可持续低碳发展必须继续通过考虑CE-RSEIC及其空间方面来进行。
    Carbon emissions have a negative impact on climate change. Environmental quality has faced significant challenges in the last decades. Eco-environmental quality helps assess the condition of the ecological environment to support humans\' civilization and development. By using emissions raster dataset, remote sensing images, and LULC data, this study explores the status of carbon emissions (CE), eco-environmental quality (RSEICs), and the dynamic relationship between both variables in Samarinda Metropolitan Area, Indonesia. This study uses the spatiotemporal approach to deepen the understanding of CE-RSEICs during 2000-2021. The methods include the analysis of CE and the principal component of RSEICs. To understand the CE-RSEICs spatial features, the directional distribution ellipse method is used. Also, this study performs CE-RSEICs coupling analysis and identifies its LULC type composition. The findings show that CE status is still on an increasing trend, concentrating in the eastern region and keeping expanding during the period. The location of the low-emission ellipse is in the southwest, while the high-emission ellipse is in the east and intersects with the core cities. The mean RSEICs value is between 0.2878 to 0.4223, which indicates that the eco-environmental quality is categorized as fairly poor to inferior. Greenness, wetness, and Csink have a positive impact on RSEICs. The very poor-class ellipse is located in the inland region, and the very good-class ellipse is in the coastal area. The CE-RSEICs coupling status shows that the majority of the area has a weaker coupling degree. However, the higher coupling degree is concentrated in the population center and built-up region, which is the settlement area. The dominance composition of settlement area in higher coupling degree shows that settlement area has an impact on increasing CE-RSEICs coupling degree. So, sustainable low carbon development in coastal metropolitan area must continue to be carried out by considering CE-RSEICs and its spatial aspects.

    近年来,能源扶贫已成为一个关键的经济问题。鉴于大量的人没有必要的能源服务,一个关键的问题是,普及电气化是否会严重影响环境质量。本研究评估了南亚经济体中不对称的能源贫困-环境质量关系。以前的工作采用面板数据技术,得出了关于能源贫困-环境质量关系的独特结论,不管几个国家不能单独建立这样的相关性的事实。这项研究,相反,应用分位数对分位数的方法,它使所有国家的时间序列互连的独立确定能够提供关于变量之间关系的全球但经济特有的证据。结果表明,在特定的数据分布分位数下,能源贫困会降低大多数选定经济体的环境质量。此外,研究结果表明,变量之间的不对称程度因国家而异,强调政府在接受与能源贫困和环境质量有关的政策时必须特别注意。
    Energy poverty alleviation has emerged as a critical economic problem in recent years. Given the enormous number of people without essential energy services, a crucial concern is whether providing universal access to electrification will considerably affect environmental quality. The present research evaluates the asymmetric energy poverty-environmental quality nexus in South Asian economies. Previous works adopted panel data techniques, resulting in distinctive conclusions about the energy poverty-environmental quality nexus, irrespective of the truth that several nations could not establish such a correlation separately. This research, conversely, applies the Quantile-on-Quantile methodology, which enables independent determinations of time-series interconnection in all nations to offer worldwide yet economy-particular evidence concerning the relationship between the variables. The results indicate that energy poverty degrades environmental quality in most selected economies at particular data distribution quantiles. Moreover, the findings disclose that the ranks of asymmetries between the variables change by country, emphasizing the requirement of governments to take special care when accepting policies linked to energy poverty and environmental quality.

    全球监管机构制定农药环境质量标准,它们是在每个依赖的环境媒体中独立提出的,而不是在完整的命运路线中提出的。因此,在定义农药环境质量标准时缺乏归宿途径的观点可能会导致上隔室中不受欢迎的农药残留(例如,土壤)到下部隔间(例如,水)。本研究旨在通过命运途径分析来协调环境介质中农药环境质量标准的自洽。引入的定性和定量规则根据相关监管目标,在土壤和水系统的六个主要环境情景中定义了农药的环境质量标准。通过USEtox模拟的命运因素用于在环境区隔中农药的理论最大合法质量之间建立初步的定量联系。以毒死蜱和2,4-D为例,他们的标准值在中国和美国的选定环境媒体中进行了比较评估。根据调查结果,缺少农业土壤中农药的环境质量标准可能会严重影响淡水农药的实施。从命运路径的角度来看,自我一致性测试强调,定义淡水农药环境质量标准是最具挑战性的任务,因为淡水隔间通常包括多个较低的环境隔间,具有不同的监管目标。总的来说,这一理论研究有可能阐明农药环境质量标准在整个环境归宿过程中的协调,最终导致监管效率和沟通的提高。未来的研究应该集中在基于风险的模型实施上,监管响应评估,和法律限制解释,以更好地整合各种监管目标下的环境农药管理。
    Regulatory agencies worldwide set pesticide environmental quality standards, which are proposed independently in each dependent environmental media rather than across the complete fate route. Thus, lacking the fate-pathway perspective in defining pesticide environmental quality standards might cause undesirable pesticide residue from the upper compartment (e.g., soil) to the lower compartment (e.g., water). This study aimed to harmonize the self-consistency of pesticide environmental quality standards across environmental media via the fate-pathway analysis. The introduced qualitative and quantitative rules defined environmental quality standards of pesticides in six major environmental scenarios in the soil and water system based on related regulatory objectives. Fate factors simulated via USEtox were used to create a preliminary quantitative link between theoretical maximum legal masses of pesticides across environmental compartments. Using chlorpyrifos and 2,4-D as examples, their standard values were comparatively assessed in selected environmental media in China and the United States. According to the investigative findings, missing the respective environmental quality standards of pesticides in the agricultural soil could significantly influence the implementation of those in freshwater. Taking a fate-pathway perspective, the self-consistency test highlighted that defining pesticide environmental quality standards for freshwater was the most challenging task, as the freshwater compartment typically comprises multiple lower environmental compartments with diverse regulatory objectives. Overall, this theoretical study has the potential to illuminate the harmonization of pesticide environmental quality standards throughout the entire environmental fate pathway, ultimately leading to improved regulatory efficiency and communication. Future research should focus on risk-based model implementation, regulatory response evaluation, and legal limit interpretation to better integrate environmental pesticide management under a variety of regulatory goals.

    乡村旅游刺激了经济增长和就业,但由于能源需求而损害了环境。这项研究说明了能源的使用,全球化,和经济增长来评估和减轻乡村旅游的环境影响。对于2001Q1至2019Q4的数据,采用GMM方法分析了乡村旅游企业的环境影响。调查结果表明,乡村旅游相关的餐饮服务增加了大量和积极的整体环境质量,除了N2O。然而,食品和饮料服务对温室气体排放和空气污染中的PM2.5产生负面影响。观光会伤害温室气体排放,同时对空气污染产生积极影响。此外,旅行对空气污染物中的CO排放有相当大的负面影响。能源使用仅对CO2和CO有重大影响,但GDP对N2O排放有负面影响。全球化对二氧化碳和PM2.5以外的空气污染物产生负面影响。与乡村旅游相关的餐饮服务对整体环境质量有积极影响,不包括N2O排放。乡村旅游的食品和饮料服务危害温室气体排放(包括CO2)和空气污染(尤其是PM2.5)。旅行对CO排放有显著的负面影响,但是观光有双重影响,既对温室气体排放产生负面影响,也对空气污染产生积极影响。此外,购物和休闲对我国整体环境质量影响不大。关键努力的政策后果也得到了解决。
    Rural tourism spurs economic growth and jobs but harms the Environment due to energy demands. The study accounts for energy use, globalization, and economic growth to assess and mitigate rural tourism\'s environmental impact. For data covering 2001Q1 to 2019Q4, GMM approaches are utilized to analyze the environmental implications of rural tourist enterprises. The findings suggest that rural tourism-related catering services increased substantial and positive overall environmental quality, except N2O. However, food and beverage services negatively influence greenhouse gas emissions and only PM2.5 in air pollution. Sightseeing hurts greenhouse gas emissions while having a positive impact on air pollution. Furthermore, traveling has a considerable negative influence on CO emissions in air pollutants. Energy use only has a substantial influence on CO2 and CO, but GDP has a negative impact on N2O emissions. Globalization has a negative impact on CO2 and air pollutants other than PM2.5. Catering services associated with rural tourism positively affect overall environmental quality, excluding N2O emissions. Rural tourism\'s food and beverage services harm greenhouse gas emissions (including CO2) and air pollution (particularly PM2.5). Traveling has a significant negative impact on CO emissions, but sightseeing has a dual impact, both negative on greenhouse gas emissions and positive influence on air pollution. Furthermore, shopping and leisure have little impact on overall environmental quality in China. The crucial efforts\' policy ramifications are addressed as well.

    到目前为止,对城市绿地(UGS)游客情绪的综合分析在很大程度上仍未被探索。在这项研究中,我们专注于UGS的环境偏好,恢复性,其他物理因素(声音,空气,和热环境),和影响访客情绪的个体特征。这样的综合分析将使相关从业人员能够检查UGS的环境质量,并改善某些条件以促进游客的情绪。
    通过独立样本t检验分析了总共904份同时监测物理因素的问卷答复,单向方差分析和路径分析。
    热评估对积极情绪的影响最大(β=0.474),其次是感知恢复性(β=0.297),其β值分别为-0.120和-0.158,负面情绪。空气评估对增加积极情绪(β=0.293)比减少消极情绪(β=-0.115)更有效。声音评估也有类似的结果(β=0.330与β=-0.080)。环境偏好仅显著影响积极情绪(β=0.181),但仍可间接影响消极情绪。此外,客观的身体因素可以通过增强游客的评价间接影响他们的情绪。.
    不同的UGS环境因素对访客情绪的影响各不相同,它们对积极情绪和消极情绪的影响也是如此。UGS通常对积极情绪的影响大于消极情绪。游客情绪主要受生理和心理因素的影响。本研究对UGS的设计和管理提出了相应的建议。
    To date, a comprehensive analysis of urban green space (UGS) visitors\' emotional remains largely unexplored. In this study, we focus on how UGS environmental preferences, restorativeness, other physical factors (sound, air, and thermal environments), and individual characteristics affecting visitor emotions. Such a comprehensive analysis would allow relevant practitioners to check the environmental quality of UGSs and improve certain conditions to promote visitor emotions.
    A total of 904 questionnaire responses with concurrently monitored physical factors were analyzed by independent sample t-tests, one-way ANOVA and path analysis.
    The thermal evaluation had the largest impact on positive emotions (β = 0.474), followed by perceived restorativeness (β = 0.297), which had β values of -0.120 and -0.158, respectively, on negative emotions. Air evaluation was more effective for increasing positive emotions (β = 0.293) than reducing negative emotions (β = -0.115). Sound evaluation also had similar results (β = 0.330 vs. β = -0.080). Environmental preference significantly influenced only positive emotions (β = 0.181) but could still indirectly impact negative emotions. Moreover, objective physical factors can indirectly affect visitors\' emotions by enhancing their evaluations..
    The influence of different UGS environmental factors on visitors\' emotions vary, as does their impacts on positive versus negative emotions. Positive emotions were generally more affected than negative emotions by UGS. Visitor emotions were mainly influenced by physical and psychological factors. Corresponding suggestions are proposed for UGS design and management in this study.

    这项研究的主要目的是研究绿色能源和公共投资对北非二氧化碳排放的影响。此外,该研究还检验了1995年至2018年间北非国家是否存在N形环境库兹涅茨曲线(EKC)假设。这些因素使用动态普通最小二乘(DOLS)进行分析,完全修正的普通最小二乘(FMOLS),和集合均值群(PMG)估计器,以获得异质参数的估计。这些测试和检查的结果表明,证实了N形曲线。其次,研究结果还证明了可再生能源作为减少碳排放的生态友好型创新的有效性。这一发现突出了可再生能源在排放比传统能源更少的碳排放方面可能产生的积极影响。此外,公共投资,这解释了政府支出,北非国家的二氧化碳排放量增加,导致环境退化。此外,研究结果还表明,二氧化碳排放与经济发展之间的相关性产生了权衡效应。基于这些发现,该研究建议北非国家的经济政策制定者优先考虑转变政府支出结构,以改善环境质量,优化非环境友好型能源收入利用,加快能源转型,加大可再生能源的开发力度,提高社会的环保意识。通过执行这些建议,北非国家可以在减少碳足迹的同时平衡经济增长和环境质量。
    The main objective of this study is to examine the impacts of green energy and public investment on the CO2 emissions in North Africa. Moreover, the study also tests the existence of the N-shaped Environmental Kuznets Curve (EKC) hypothesis for North African countries between 1995 and 2018. These factors were analyzed using the Dynamic Ordinary Least Squares (DOLS), Fully Modified Ordinary Least Squares (FMOLS), and Pooled Mean Group (PMG) estimators to obtain estimations of heterogeneous parameters. The outcome of these tests and examinations showed that the N-shaped curve was confirmed. Secondly, The results of the study also demonstrate the effectiveness of renewable energy as an eco-friendly innovation in reducing carbon emissions. This finding highlights the positive impact that renewable energy sources can have in terms of emitting fewer carbon emissions compared to traditional energy sources. Moreover, public investment, which interprets government expenditure, and urbanization contribute to environmental degradation by increasing CO2 emissions in the case of North African countries. Furthermore, the findings also indicated a trade-off effect resulting from the correlation between CO2 emissions and economic development. Based on these findings, the study recommends that economic policymakers in North African countries prioritize transforming the structure of government expenditures to improve environmental quality, optimize the utilization of revenues from non-environmentally friendly energy resources to accelerate the energy transition, increase the exploitation of renewable energy, and promote environmental awareness in society. By implementing these recommendations, North African countries can balance economic growth and environmental quality while reducing their carbon footprint.

    全球可持续发展需要促进可再生能源和优化产业结构。本研究采用面板向量自回归(PVAR)模型来检验能量结构之间的动态关系,产业结构,环境质量,1990年至2021年金砖国家的城市化进程。能源结构,产业结构,环境质量,和城市化的实证协整。能源结构优化和产业结构升级可以改善环境质量。能源增强也支持城市化。加快工业变革可能对城市化产生不利影响。脉冲响应结果表明,扩大可再生能源和第三产业如金融和服务业促进了环境质量和城市化。方差分解调查揭示了减少碳排放和增加城市化的显着“路径依赖”。最后,根据调查结果,对提高环境质量和促进城市化的政策见解进行了阐述和争议,对环境管理者和城市规划者有长期影响。
    Global sustainable development demands boosting renewable energy and optimizing industrial structures. This study employs a panel vector autoregressive (PVAR) model to examine the dynamic relationship between energy structure, industrial structure, environmental quality, and urbanization in the BRICS countries from 1990 to 2021. Energy structure, industrial structure, environmental quality, and urbanization cointegrate empirically. Energy mix optimization and industrial structure upgrades can improve environmental quality. Energy enhancements also supported urbanization. Accelerating industrial change could adversely impact urbanization. The impulse response results demonstrate that expanding renewable energy and tertiary industries such as financial and service boost environmental quality and urbanization. The variance decomposition investigation reveals significant \"path dependence\" in reducing carbon emissions and increasing urbanization. Finally, based on the findings, policy insights for enhancing environmental quality and fostering urbanization are laid out and disputed, with long-term implications for environmental managers and urban planners.
