Rapid industrialization in recently industrialized countries (NICs) has exacerbated environmental degradation, raising urgent concerns about how energy consumption, gold prices, and fossil fuel prices contribute to this growing issue. This study aims to evaluate the asymmetric relationships between these factors and environmental degradation across 10 NICs, including Brazil, India, South Korea, Mexico, Indonesia, Turkey, Thailand, South Africa, Malaysia, and the Philippines, from 1995 to 2023. Using the CS-ARDL model, our study demonstrates that while energy costs and renewable energy consumption reduce environmental degradation, gold prices and fossil fuel consumption significantly increase ecological harm. Additionally, the study employs FGLS, CS-DL, AMG, and Driscoll-Kray to verify the robustness of these findings. Notably, the Environmental Kuznets Curve (EKC) hypothesis holds true in these economies. Key results show that a 1 % increase in renewable energy use decreases emissions by 0.7 %, while a 1 % rise in gold prices correlates with a 0.5 % increase in pollution levels. These findings underscore the need for NICs to implement green investments, promote renewable energy, and initiate structural reforms to ensure sustainable development.
近代工业化国家(NICs)的快速工业化加剧了环境退化,引发了人们对能源消耗、黄金价格和化石燃料价格如何导致这一日益严重问题的迫切关注。本研究旨在评估巴西、印度、韩国、墨西哥、印度尼西亚、土耳其、泰国、南非、马来西亚和菲律宾等 10 个新工业化国家在 1995 年至 2023 年期间这些因素与环境退化之间的不对称关系。利用 CS-ARDL 模型,我们的研究表明,虽然能源成本和可再生能源消费减少了环境退化,但黄金价格和化石燃料消费却显著增加了生态危害。此外,研究还采用了 FGLS、CS-DL、AMG 和 Driscoll-Kray 来验证这些结论的稳健性。值得注意的是,环境库兹涅茨曲线(EKC)假设在这些经济体中成立。主要结果显示,可再生能源使用每增加 1%,排放量就会减少 0.7%,而金价每上涨 1%,污染水平就会增加 0.5%。这些研究结果突出表明,新工业化国家需要实施绿色投资、推广可再生能源并启动结构改革,以确保可持续发展。

This article investigates temporal matching requirements between electrolytic hydrogen production and dedicated renewable electricity generation for the hydrogen to qualify as “green”. In contrast to previous studies, which found that a more granular matching increases production costs, we study cost advantages for hourly matching through technological and spatial diversification. To this end, we develop and apply a linear cost-optimization model to quantify the resulting portfolio effects. We identify two types of portfolio effects, “technological” and “locational” ones, and quantify these for different portfolio sizes and types of power generation technologies in Germany. Portfolio effects turn out to be in the range of 3–8% when aggregating two locations, and up to 21 % for a nation-wide portfolio. Finally, we discuss the implications of our findings in terms of discrimination against small players and for the modeling of temporal matching requirements.
本文研究了电解氢气生产与专用可再生能源发电之间的时间匹配要求,以使氢气符合 "绿色 "标准。以往的研究发现,更精细的匹配会增加生产成本,与此不同,我们研究了通过技术和空间多样化实现每小时匹配的成本优势。为此,我们开发并应用了一个线性成本优化模型来量化由此产生的组合效应。我们确定了两种类型的组合效应,即 "技术 "效应和 "地点 "效应,并针对德国不同的组合规模和发电技术类型对其进行了量化。结果表明,当两个地点的组合效应为 3-8% 时,全国范围内的组合效应可达 21%。最后,我们讨论了我们的研究结果对小型参与者的歧视以及对时间匹配要求建模的影响。

This study examines the connection between crude oil and the Gulf Cooperation Council (GCC) region stock markets by employing a regime-switching approach. The methodology provides new insights on how the linkage between oil and GCC stock markets may fluctuate in different economic or market regimes, which is crucial for understanding the transmission of oil shocks and tailoring policy responses. The findings indicate that the spillovers between the underlying assets are asymmetric. Specifically, during the turmoil periods, the connectedness is intense among these assets, whereas during tranquil periods, the linkage is moderate. The intense spillovers regime is short-lived, which corroborates the existing literature of a relatively stable oil market. Furthermore, an increase in oil prices can positively contribute to the profits of firms that are heavily dependent on oil, leading to an increase in the linkage between these countries and crude oil. Results have crucial suggestions for investors and decision-makers in the GCC region.
本研究采用制度转换方法研究了原油与海湾合作委员会(GCC)地区股票市场之间的联系。该方法提供了关于石油与海湾合作委员会股票市场之间的联系在不同经济或市场制度下如何波动的新见解,这对于理解石油冲击的传导和调整政策反应至关重要。研究结果表明,相关资产之间的溢出效应是不对称的。具体来说,在动荡时期,这些资产之间的关联性很强,而在平静时期,关联性一般。激烈的溢出效应是短暂的,这与现有文献中石油市场相对稳定的观点相吻合。此外,石油价格上涨会对严重依赖石油的企业的利润产生积极影响,从而导致这些国家与原油之间的联系增加。研究结果为海湾合作委员会地区的投资者和决策者提供了重要建议。

Based on system theory and the configuration perspective, this study uses the panel data-based qualitative comparison (PD-QCA) method in R and the panel data of the energy systems of China and the ‘Belt and Road’ countries from 1998 to 2020 to analyze the driving factors that affect the green development of energy systems in various countries and the configuration effect on the vertical axis of time and its synergistic promotion path. The research results show that: (1) the driving factors for the green development of the energy systems in various countries are characterized by multiple synergies and the same goals. Factors such as the energy supply side, demand side and basic development level cannot be the necessary conditions for the green development of the energy structure alone, and it is necessary to give full play to the synergy among various factors; (2) in the sufficiency analysis, seven configuration paths are found for collaboratively driving the green development of the energy system, which can be further refined into energy supply-driven, supply-demand-driven, demand-technology-driven and supply-demand-technology-driven paths; (3) capital input, the labour supply level, government support, technological innovation and the environmental regulation level constitute the core driving factors of the green development of energy systems, and there is a potential substitution relationship between capital input and environmental regulation levels.;(4) In the temporal dimension, the Chow breakpoint test verified that the countries along the “Belt and Road Initiative” had a sense of green development to energy after 2013; in the spatial dimension, the implementation effects of each collaborative path showed obvious regional applicability differences.
本研究基于系统理论和构型视角,运用R语言中基于面板数据的定性比较(PD-QCA)方法,以1998-2020年中国和 "一带一路 "国家能源系统面板数据为研究对象,分析影响各国能源系统绿色发展的驱动因素和时间纵轴上的构型效应及其协同推进路径。研究结果表明:(1)各国能源系统绿色发展的驱动因素具有多重协同、目标一致的特点。能源供给侧、需求侧和基础发展水平等因素不能单独成为能源结构绿色发展的必要条件,需要充分发挥各因素之间的协同作用;(2)在充分性分析中,发现了协同驱动能源系统绿色发展的七种配置路径,可进一步细化为能源供给驱动、供给-需求驱动、需求-技术驱动和供给-需求-技术驱动路径;(3)资本投入、劳动力供给水平、政府支持、技术创新和环境规制水平构成了能源系统绿色发展的核心驱动因素,资本投入与环境规制水平之间存在潜在的替代关系。4)在时间维度上,周氏断点检验验证了 "一带一路 "倡议沿线国家在 2013 年后对能源的绿色发展意识;在空间维度上,各合作路径的实施效果表现出明显的区域适用性差异。

This study analyzes the causal link between technological advancement, environmental degradation, energy usage, and sustainable economic development in China. The paper looks at the extent to which expansion in energy and carbon dioxide emissions can be explained using the Environmental Kuznets Curve model. Only the annual data from the WDI is considered; therefore, only the data range from 1990 to 2019 is used. This work also uses the FMOLS technique to establish the nature of the long-run causal relationship between the variables used in the analysis and establish that environmental quality has worsened in China during the period considered. The result shows that renewable and non-renewable energy sources, along with technological advancement, have a significantly positive impact on CO2 emissions, suggesting that they are detrimental to the environment. Nevertheless, the results confirm the EKC hypothesis since the coefficient estimates for GDP growth are positive, whereas those for the square of this variable are negative. The results also highlight the existence of a unidirectional causality between the Chinese GDP and carbon emissions while reporting on a bi-directional causality between economic growth and energy consumption. This research explores the impact of technological changes and energy consumption on environmental pollution in China, examining the issue left unexplored in understanding the effects of technological change and energy usage on sustainable economic growth. Although many prior studies have focused on the EKC model, very little research has specifically explored the effects of both renewable and non-renewable energy sources on China's environmental quality. This paper is, therefore, a direct attempt at filling this gap by identifying the causal effect of these factors over the 1990–2019 period.
本研究分析了中国技术进步、环境恶化、能源使用和经济可持续发展之间的因果关系。本文探讨了使用环境库兹涅茨曲线模型解释能源和二氧化碳排放扩张的程度。本文只考虑了 WDI 的年度数据,因此只使用了 1990 年至 2019 年的数据范围。本研究还使用了 FMOLS 技术来确定分析中使用的变量之间的长期因果关系的性质,并确定中国的环境质量在研究期间有所恶化。结果表明,可再生能源和不可再生能源以及技术进步对二氧化碳排放有显著的正向影响,表明它们对环境不利。然而,结果证实了 EKC 假设,因为国内生产总值增长的系数估计值为正,而该变量平方的系数估计值为负。研究结果还强调了中国 GDP 与碳排放之间存在单向因果关系,同时报告了经济增长与能源消耗之间的双向因果关系。本研究探讨了技术变革和能源消耗对中国环境污染的影响,研究了在理解技术变革和能源使用对可持续经济增长的影响方面尚未被探索的问题。尽管之前的许多研究都侧重于 EKC 模型,但很少有研究专门探讨可再生能源和不可再生能源对中国环境质量的影响。因此,本文通过确定 1990-2019 年间这些因素的因果效应,直接填补了这一空白。

Alleviating energy poverty, improving the ecological environment, and promoting social welfare have become important issues in society. By taking panel data from 30 provinces in China from 2003 to 2020 as the research object, fixed effects models and system-GMM models are adopted, and the impacts of environmental regulations on social welfare and the moderating effect of energy poverty are studied in this paper. The results show that enhanced environmental regulation has a significant negative impact on social welfare, while flexible environmental regulation has the opposite, especially in energy poverty regions. Moreover, energy poverty has a significant negative impact on social welfare, and energy poverty reduces the consumption capacity of clean energy, which may pollute the environment and damage health, thus reducing social welfare. Additionally, the energy poverty has significant positive moderating effect, that is, energy poverty aggravates the inhibitory effect of enhanced environmental regulation on social welfare, and promotes the impact of flexible environmental regulation on social welfare. Finally, energy poverty varies significantly in different regions, and the energy poverty lines in the eastern, central and western regions, as well as the national are 503.381, 442.758, 359.461 and 444.546, respectively.
缓解能源贫困、改善生态环境、增进社会福利已成为社会的重要议题。本文以中国 30 个省份 2003-2020 年的面板数据为研究对象,采用固定效应模型和系统-GMM 模型,研究了环境规制对社会福利的影响以及能源贫困的调节作用。结果表明,强化环境规制对社会福利有显著的负面影响,而弹性环境规制则相反,尤其是在能源贫困地区。此外,能源贫困对社会福利有显著的负面影响,能源贫困会降低清洁能源的消费能力,从而可能污染环境、损害健康,进而降低社会福利。此外,能源贫困还具有显著的正向调节作用,即能源贫困加剧了强化环境规制对社会福利的抑制作用,促进了灵活环境规制对社会福利的影响。最后,能源贫困在不同地区存在显著差异,东部、中部和西部地区以及全国的能源贫困线分别为 503.381、442.758、359.461 和 444.546。

This research proposes a new approach to increase the utilization of electric vehicles (EVs) by establishing solar-powered charging stations. Using ArcGIS 10 8.2 software, the optimal locations for the construction of these stations were identified and all technical, economic, environmental, and geological aspects were studied more carefully. Diverging from prior research, the initiative of this research leverages public spaces such as gas stations and eco-lodges to reduce operational costs and enhance station sustainability. This method is globally applicable and sets a precedent for CO2 emission reduction within the transportation sector. Comparative and evaluative analyses of the solar electricity charging infrastructures that support the EVs with regard to the technical and functional parameters are performed. The systematic and innovative concept that has been put forward enables us to identify the places with the highest prospects regarding the construction of Solar-Powered Charging Stations for EVs across the world. As for the case of using this technique in the selected region, it proved that 18 % of the area of Qeshm Island is suitable for constructing solar-based EV-charged stations, and the demand the island will supply by 2040. In the studied region, it was determined that the type of vehicles has a significantly greater impact on energy consumption than the distance traveled by the vehicles. By opting for fuel-efficient vehicles, it is possible to supply approximately 74.96 % of the required energy through solar energy, and these vehicles can even be used for public services such as taxis that cover long distances. The findings indicate that by 2040, the area could transition 11 % of its vehicles to EVs, potentially decreasing CO2 emission by more than 34 tons.
本研究提出了一种通过建立太阳能充电站来提高电动汽车利用率的新方法。利用ArcGIS 10 8.2软件,确定了这些站点建设的最佳位置,并对所有技术、经济、环境和地质方面进行了更仔细的研究。与之前的研究不同,这项研究的倡议利用了公共空间,如加油站和生态小屋,以降低运营成本,提高车站的可持续性。该方法在全球范围内适用,并为交通运输部门的二氧化碳减排树立了先例。对支持电动汽车的太阳能充电基础设施的技术和功能参数进行了比较和评价分析。提出的系统和创新的概念使我们能够确定在全球范围内建设电动汽车太阳能充电站最有前景的地方。对于在选定地区使用该技术的案例,证明了Qeshm岛18%的面积适合建设太阳能电动汽车充电站,到2040年该岛将满足需求。在研究区域,确定车辆类型对能源消耗的影响明显大于车辆行驶距离。通过选择节能型车辆,可以通过太阳能提供大约74.96%的所需能源,这些车辆甚至可以用于长途出租车等公共服务。研究结果表明,到2040年,该地区将有11%的车辆转向电动汽车,可能减少超过34吨的二氧化碳排放。
