Carbon storage (C-storage) is a critical indicator of ecosystem services, and it plays a vital role in maintaining ecological balance and driving sustainability. Its assessment provides essential insights for enhancing environmental protection, optimizing land use, and formulating policies that support long-term ecological and economic sustainability. Previous research on C-storage in the Yellow River Basin has mainly concentrated on the spatiotemporal fluctuations of C-storage and the investigation of natural influencing factors. However, research combining human activity factors to explore the influences on C-storage is limited. In this paper, based on the assessment of the spatiotemporal evolution of C-storage in the region along the Middle and Lower Yellow River (MLYR), the influences of anthropogenic and natural factors on C-storage were explored from the perspective of sustainable development. The findings reflected the relationship between socio-economic activities and the ecological environment from a sustainable development perspective, providing important scientific evidence for the formulation of sustainability policies in the region. We noticed the proportion of arable land was the highest, reaching 40%. The increase of construction land because of the fast urbanization mainly came from arable land and grassland. During the past 15 years, the cumulative loss of C-storage was 71.17 × 106 t. The high-value of C-storage was primarily situated in hilly areas, and the area of C-storage hotspots was shrinking. The aggregation effect of low-value C-storage was strengthening, while that of high-value C-storage was weakening. The dominant factors (q > 0.5) influencing the spatiotemporal variation of C-storage in the region along the Middle Yellow River (MYR) were temperature and precipitation, while the primary factor in the region along the Lower Yellow River (LYR) was temperature. Overall, meteorological factors were the main determinants across the entire study area. Additionally, compared to the MYR, anthropogenic factors had a smaller impact on the spatiotemporal evolution of C-storage in the LYR, but their influence has been increasing over time.
碳储存(C-storage)是生态系统服务的一个重要指标,在维持生态平衡和推动可持续发展方面发挥着至关重要的作用。对其进行评估可为加强环境保护、优化土地利用以及制定支持长期生态和经济可持续发展的政策提供重要启示。以往对黄河流域碳储量的研究主要集中在碳储量的时空波动和自然影响因素的调查上。然而,结合人类活动因素探讨储碳影响因素的研究还很有限。本文在评估黄河中下游地区储碳量时空演变的基础上,从可持续发展的角度探讨了人为因素和自然因素对储碳量的影响。研究结果从可持续发展的角度反映了社会经济活动与生态环境之间的关系,为该地区制定可持续发展政策提供了重要的科学依据。我们注意到耕地比例最高,达到 40%。快速城市化带来的建设用地增加主要来自耕地和草地。过去 15 年,贮存量累计损失 71.17×106 t。贮存量高值区主要分布在丘陵地区,贮存量热点地区面积不断缩小。低值储碳的聚集效应增强,而高值储碳的聚集效应减弱。影响黄河中游地区储碳量时空变化的主导因子(q>0.5)是气温和降水,而黄河下游地区的主导因子是气温。总体而言,气象因素是整个研究区域的主要决定因素。此外,与多年平均气温相比,人为因素对涟水地区碳储量时空演变的影响较小,但随着时间的推移,其影响在不断增加。

The first-person pronoun is an indispensable element of the communication process. Meanwhile, leadership effectiveness, as the result of leaders’ leadership work, is the key to the sustainable development of leaders and corporations. However, due to the constraints of traditional methods and sample bias, it is challenging to accurately measure and validate the relationship between first-person pronouns and leadership effectiveness at the implicit level. Word Embedding Association Test (WEAT) measures the relative degree of association between words in natural language by calculating the difference in word similarity. This study employs the word and sentence vector indicators of WEAT to investigate the implicit relationship between first-person pronouns and leadership effectiveness. The word vector analyses of the Beijing Normal University word vector database and Google News word vector database demonstrate that the cosine similarity and semantic similarity of “we-leadership effectiveness” are considerably greater than that of “I-leadership effectiveness”. Furthermore, the sentence vector analyses of the Chinese Wikipedia BERT model corroborate this relationship. In conclusion, the results of a machine learning-based WEAT verified the relationship between first-person plural pronouns and leadership effectiveness. This suggests that when leaders prefer to use “we”, they are perceived to be more effective.
第一人称代词是传播过程中不可或缺的要素。同时,领导效能作为领导者领导工作的结果,是领导者和企业可持续发展的关键。然而,由于传统方法和样本偏差的限制,要在内隐层面上准确测量和验证第一人称代词与领导效能之间的关系具有挑战性。词语嵌入关联测试(WEAT)通过计算词语相似度的差异来衡量自然语言中词语之间的相对关联程度。本研究利用 WEAT 的词向量和句向量指标来研究第一人称代词与领导效能之间的内隐关系。对北京师范大学词向量数据库和谷歌新闻词向量数据库进行的词向量分析表明,"我们-领导效能 "的余弦相似度和语义相似度都大大高于 "我-领导效能"。此外,中文维基百科 BERT 模型的句向量分析也证实了这一关系。总之,基于机器学习的 WEAT 的结果验证了第一人称复数代词与领导效能之间的关系。这表明,当领导者喜欢使用 "我们 "时,他们会被认为更有效率。

Digital Inclusive Finance, Digital Technology Innovation, and Carbon Emission Intensity 数字普惠金融、数字技术创新与碳排放强度
Pub Date : 2024-07-26 DOI: 10.3390/su16156407
Qi He, Hongli Jiang
Decreasing carbon emission intensity (CEI) has emerged as a crucial strategy for nations to attain low-carbon economic growth. Nevertheless, a definitive conclusion about the correlation between financial development and CEI has not been reached. This research examines the influence of digital inclusive finance (DIF), a novel financial sector, on CEI, and the role of digital technology innovation (DTI) in this impact. Firstly, this study analyzes the influence of DIF on CEI from the perspectives of technology effect and scale effect and proposes the hypothesis that the impact of DIF on CEI is U-shaped. Then, using a double fixed-effect model and a sample of 30 provinces in China from 2011 to 2021, this study verifies the accuracy of the hypothesis. Subsequently, this study examines the mechanism by which DIF impacts CEI, and the results indicate that DIF can exert a U-shaped influence on CEI via enhancing DTI. Then, this study further investigates the impact of DIF on CEI from three angles: geographical location, human capital level, and green finance. It also explores the geographical spillover effect and spatial heterogeneity by employing the Durbin model. Lastly, drawing from the aforementioned analysis, this report proposes some recommendations.
降低碳排放强度(CEI)已成为各国实现低碳经济增长的重要战略。然而,金融发展与碳排放强度之间的相关性尚未得出明确结论。本研究探讨了数字普惠金融(DIF)这一新型金融领域对 CEI 的影响,以及数字技术创新(DTI)在这一影响中的作用。首先,本研究从技术效应和规模效应的角度分析了 DIF 对 CEI 的影响,并提出了 DIF 对 CEI 的影响呈 U 型的假设。然后,本研究采用双固定效应模型,以 2011-2021 年中国 30 个省份为样本,验证了假设的准确性。随后,本研究考察了 DIF 对 CEI 的影响机制,结果表明 DIF 可以通过增强 DTI 对 CEI 产生 U 型影响。然后,本研究从地理位置、人力资本水平和绿色金融三个角度进一步研究了 DIF 对 CEI 的影响。本研究还利用杜宾模型探讨了地理溢出效应和空间异质性。最后,在上述分析的基础上,本报告提出了一些建议。

The role of technology in e-waste management is receiving increasing attention as a dominant strategy to achieve long-term sustainability and well-being goals. However, a lack of comprehensive understanding of the contemporary factors influencing e-waste urban mining technology design and adoption remains. This is the first study to propose a taxonomy to clarify the contemporary factors influencing e-waste urban mining technology design and adoption. The taxonomy comprises four thematic clusters, notably the device cluster, the process cluster, the organizational cluster, and the macro cluster. This study further shares insights on how the taxonomy of e-waste urban mining technology design and adoption can be applied to assess each stage of the technology transition process. Drawing from this study synthesis, this study taxonomy model characterizes the embedded internal and external various states of technology design and adoption and derives informed decisions from a sustainable technology perspective. This study’s taxonomy framework supports the outlook measurement analysis of e-waste urban mining technology factors from both developing and developed countries’ perspectives, which can contribute to broadening the scope and level of the applicability of technologies.
作为实现长期可持续发展和福祉目标的主导战略,技术在电子废物管理中的作用正受到越来越多的关注。然而,人们对影响电子垃圾城市开采技术设计和采用的当代因素仍缺乏全面了解。本研究首次提出了一种分类法,以阐明影响电子废物城市开采技术设计和采用的当代因素。该分类法包括四个专题组,即设备组、流程组、组织组和宏观组。本研究还就如何应用电子废弃物城市开采技术设计与采用分类法评估技术过渡过程的各个阶段分享了见解。本研究的分类模型从本研究综述中汲取营养,描述了技术设计和采用的内部和外部各种嵌入状态,并从可持续技术的角度得出了明智的决策。本研究的分类框架支持从发展中国家和发达国家的角度对电子废弃物城市开采技术因素进行展望测量分析,有助于拓宽技术的适用范围和水平。

Charting Pollution Effects on Tourism: A Regional Analysis 绘制污染对旅游业影响的图表:地区分析
Pub Date : 2024-07-26 DOI: 10.3390/su16156391
Dachen Sheng, Heather A. Montgomery
This study presents empirical findings highlighting the role of pollution control measures in shaping the trajectory of local tourism market development. Analysis of provincial-level panel data underscores the pronounced impact of water pollution compared to air pollution. While water pollution tends to manifest as a localized issue, air pollution transcends provincial boundaries, posing challenges that extend across multiple regions simultaneously. The results demonstrate how imperative it is for northern China’s heavily polluted provinces to redouble efforts aimed at ameliorating their negative image within the tourism market. In contrast to their southern counterparts, these regions currently face hurdles in attracting tourists, underscoring the disparity in tourism acceptance between northern and southern provinces. Drawing insights from the successful implementation of tourism initiatives centered on the small-town economy in southern China, this research advocates for a paradigm shift in policy formulation for northern provinces. By leveraging lessons learned from southern counterparts, policymakers can chart a course toward sustainable tourism development tailored to the unique characteristics of each region. In delineating the differential impacts of air and water pollution on the Chinese tourism market, this study contributes to a nuanced understanding of tourism dynamics across provinces. The findings serve as a foundational framework for guiding future tourism market development strategies tailored to the heterogeneous landscape of Chinese provinces.
本研究通过实证研究发现,污染控制措施在影响当地旅游市场发展轨迹方面发挥着重要作用。对省级面板数据的分析强调了水污染与空气污染相比所产生的显著影响。水污染往往表现为局部问题,而空气污染则超越省界,同时对多个地区构成挑战。研究结果表明,中国北方污染严重的省份必须加倍努力,改善其在旅游市场中的负面形象。与南方省份相比,这些地区目前在吸引游客方面面临重重障碍,凸显了南北方省份在旅游接受度方面的差异。本研究从中国南方成功实施的以小城镇经济为中心的旅游计划中汲取了灵感,倡导北方省份在政策制定方面进行范式转变。通过借鉴南方的经验教训,政策制定者可以根据每个地区的独特性,制定出一条可持续旅游业发展的道路。通过描述空气污染和水污染对中国旅游市场的不同影响,本研究有助于深入了解各省的旅游动态。研究结果可作为指导未来旅游市场发展战略的基础框架,以适应中国各省的不同情况。

The net carbon effect of farming is crucial for climate change mitigation, yet there is insufficient research on the impact of land management scale on it in China. This study aims to explore the magnitude and role of land management scale on the net carbon effect of farming at the spatial level, including threshold characteristics. Unlike previous studies focused on the domestic agricultural economy, this study employs ecological findings to calculate carbon sinks and certain carbon emissions. The carbon-balance ratio is used to characterise the net carbon effect of farming. The spatial Durbin model and threshold regression model were utilised with a sample of 30 provincial-level regions in China from 2004 to 2019. The results indicate that national farming generally exhibits a net sink effect, with significant interannual fluctuations. After applying robust standard errors, the expansion of the land management scale significantly increases sinks and reduces emissions, and it has a positive spatial spillover effect on the carbon-balance ratio, demonstrating significant spatial heterogeneity. Furthermore, as the land management scale expands, the influence of rural residents’ income and education level on the carbon-balance ratio changes direction, showing significant non-linear relationship characteristics.
农业生产的净碳效应对减缓气候变化至关重要,但目前国内关于土地经营规模对其影响的研究尚不充分。本研究旨在从空间层面探讨土地经营规模对农业净碳效应的影响程度和作用,包括阈值特征。与以往侧重于国内农业经济的研究不同,本研究采用生态学研究成果来计算碳汇和一定的碳排放量。碳平衡比用于描述农业的净碳效应。以 2004 年至 2019 年中国 30 个省级地区为样本,采用空间杜宾模型和阈值回归模型。结果表明,全国种植业总体上表现出净碳汇效应,且年际波动显著。在应用稳健标准误差后,土地经营规模的扩大显著增加了碳汇,减少了碳排放,并对碳平衡比产生了积极的空间溢出效应,显示出显著的空间异质性。此外,随着土地经营规模的扩大,农村居民收入和受教育程度对碳平衡率的影响也发生了方向性变化,表现出明显的非线性关系特征。

The allure of urban green spaces has captured the attention of researchers, especially in regions abundant in botanical wonders worldwide. Surprisingly, the case of Morocco, a country with a strong botanical tradition, has received little attention from researchers. Here, we explore the unique case of the emblematic “Majorelle Garden” in Marrakech, southern Morocco, through the reviews of its many visitors posted on the TripAdvisor platform. This article looks at the question “to what extent can a garden—such as the Majorelle—be a major attraction in a cultural tourist destination?”. Methodologically, we adopted a quantitative approach, examining visitors’ sentiments using the VADER tool from 2006 to 2023, and classifying them into three categories: negative, neutral, and positive. Furthermore, by utilizing LDA (latent Dirichlet allocation), we uncover key topics running through visitors’ experiences. Our findings show that positive sentiments prevail, given the culturo-historical and symbolic quality of the garden as a crucible and vector of creativity, with the emergence of sub-corpuses that highlight certain divergences and convergences around the “Majorelle” case. This insight supports sustainability efforts by empowering the managers of the garden studied and industry professionals to develop and implement relevant strategies for managing and marketing the garden tourism attraction experience. In addition, this case study shows how a private urban garden reveals its key role in preserving cultural and botanical heritage, essential for future generations. It shows the garden’s positive impact on sustainable tourism through its ability to attract cultural visitors who appreciate and respect the local environment.
城市绿地的魅力吸引了研究人员的注意力,尤其是在世界各地植物奇观丰富的地区。令人惊讶的是,摩洛哥这个有着深厚植物学传统的国家却很少受到研究人员的关注。在此,我们将通过 TripAdvisor 平台上众多游客的评论,探讨摩洛哥南部马拉喀什具有象征意义的 "马约雷尔花园 "这一独特案例。本文探讨的问题是 "像马约雷尔花园这样的花园能在多大程度上成为文化旅游目的地的主要景点?在方法上,我们采用了定量方法,使用 VADER 工具研究了 2006 年至 2023 年期间游客的情绪,并将其分为三类:负面、中性和正面。此外,我们还利用 LDA(潜在 Dirichlet 分配)发现了贯穿游客体验的关键主题。我们的研究结果表明,鉴于花园作为创造力的熔炉和载体所具有的文化历史和象征意义,积极情绪占主导地位,并出现了一些子群,这些子群突出了围绕 "马约雷尔 "案例的某些分歧和趋同。这种洞察力支持了可持续发展工作,使所研究花园的管理者和行业专业人士有能力制定和实施相关战略,以管理和营销花园旅游景点体验。此外,本案例研究还展示了一个私人城市花园如何在保护对后代至关重要的文化和植物遗产方面发挥关键作用。它还展示了该花园通过吸引欣赏和尊重当地环境的文化游客,对可持续旅游业产生的积极影响。

Here, we explore the unique case of the emblematic “Majorelle Garden” in Marrakech, southern Morocco, through the reviews of its many visitors posted on the TripAdvisor platform. This article looks at the question “to what extent can a garden—such as the Majorelle—be a major attraction in a cultural tourist destination?”. Methodologically, we adopted a quantitative approach, examining visitors’ sentiments using the VADER tool from 2006 to 2023, and classifying them into three categories: negative, neutral, and positive. Furthermore, by utilizing LDA (latent Dirichlet allocation), we uncover key topics running through visitors’ experiences. Our findings show that positive sentiments prevail, given the culturo-historical and symbolic quality of the garden as a crucible and vector of creativity, with the emergence of sub-corpuses that highlight certain divergences and convergences around the “Majorelle” case. This insight supports sustainability efforts by empowering the managers of the garden studied and industry professionals to develop and implement relevant strategies for managing and marketing the garden tourism attraction experience. In addition, this case study shows how a private urban garden reveals its key role in preserving cultural and botanical heritage, essential for future generations. It shows the garden’s positive impact on sustainable tourism through its ability to attract cultural visitors who appreciate and respect the local environment.","PeriodicalId":509360,"journal":{"name":"Sustainability","volume":"15 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141803158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inconsistency of interests among local governments, polluting companies, and the public reduces the efficiency of environmental pollution control, posing a significant challenge in harmonizing these interests to achieve environmental sustainability in China’s new-type urbanization. To elucidate the strategic decision-making rules of each party in environmental pollution control, this study constructs a tripartite evolutionary game model and analyzes the evolutionary stable strategies (ESS), identifying the influencing factors of the parties’ strategies. Subsequently, numerical simulations are used to examine the asymptotic stability of various ESS and the effects of parameter variation on these ESS. The results indicate the existence of optimal ESS wherein all three parties adopt environmentally friendly strategies. Specifically, local governments can mitigate expenses for polluting companies to implement low-pollution strategies, while concurrently facilitating public participation in pollution control. Public participation can enhance the supervisory capabilities of local governments and exert a positive influence on polluting companies. Furthermore, the simulation results suggest that the ESS of the parties can evolve into the expected ESS by adjusting the influencing factors reasonably, thereby supporting environmental sustainability in China’s new-type urbanization.
地方政府、污染企业和公众之间的利益不一致降低了环境污染治理的效率,为协调各方利益以实现中国新型城镇化进程中的环境可持续发展带来了巨大挑战。为阐明各方在环境污染治理中的战略决策规则,本研究构建了三方演化博弈模型,并对演化稳定策略(ESS)进行了分析,找出了各方策略的影响因素。随后,通过数值模拟研究了各种进化稳定策略的渐进稳定性以及参数变化对这些进化稳定策略的影响。结果表明,在三方都采取环保策略的情况下,存在最优 ESS。具体来说,地方政府可以减轻污染企业实施低污染战略的费用,同时促进公众参与污染控制。公众参与可以增强地方政府的监督能力,对污染企业产生积极影响。此外,模拟结果表明,通过合理调整影响因素,各方的环境可持续发展水平可以演变为预期的环境可持续发展水平,从而支持中国新型城镇化的环境可持续发展。

Product design is an innovative process that, through the stages of problem statement, concept, and initial and detailed design, meets the needs of customers, the requirements of companies, and their limitations. In the current process of product design and development, formulating design objectives plays a crucial role in objective setting, project implementation, product needs and requirements specification, and performing activities validation. Currently, the role of the design and development stages in the sustainability of products, identifying strategies for improving this stage is of particular significance, and paying attention to the product planning and definition process group and focusing on establishing sustainability principles in the target book and defining new attributes can be regarded as one of the sustainable product development strategies. Consequently, this research is a case study in the field of applying the sustainability principles in the target book as one of the deliverables at the stage of product planning. The present study proposes strategies towards developing the attributes of the target book as a tool for exerting sustainability pillars in the process of design and development by means of surveying automotive industry experts, applying the DEMATEL and Fuzzy ANP combined method, and evaluating and determining new attributes.

The Influence Mechanism of Bidirectional Foreign Direct Investment on Green Total Factor Productivity in China’s Manufacturing Industry 双向外商直接投资对中国制造业绿色全要素生产率的影响机制
Pub Date : 2024-07-25 DOI: 10.3390/su16156386

Recently, China has actively advocated green transformation in manufacturing. This paper applies the Malmquist–Luenberger (ML) index method to measure the green total factor productivity (GTFP) and its decomposition of 28 segments of China’s manufacturing industry from 2004 to 2020; then, it empirically investigates their causal relationship and impact mechanism on bidirectional foreign direct investment (FDI). The results show that inward foreign direct investment (IFDI) and outward foreign direct investment (OFDI) significantly inhibit GTFP, whereas the interactive development level between the two (DFDI) significantly promotes GTFP during the sample period. After decomposing GTFP, it is found that IFDI or OFDI has a significant promotional effect on green technical change (GTC) but an inhibitory effect on green technical efficiency change (GEC), while DFDI has a promotional effect on GTC or GEC. Further research also finds that OFDI can effectively weaken the inhibitory effects in the long run; IFDI, OFDI, and DFDI have the same direction of impact on GTFP or GEC, only showing heterogeneity at the significant level, while their impact on GTC has uncertainty in different types of manufacturing industries. The more rational the manufacturing industry structure, the more significant the promotional effect of IFDI, OFDI, and DFDI on GTFP.
近来,中国积极倡导制造业绿色转型。本文运用Malmquist-Luenberger(ML)指数法测算了2004-2020年中国制造业28个细分行业的绿色全要素生产率(GTFP)及其分解,并实证研究了它们与双向外商直接投资(FDI)的因果关系和影响机制。结果表明,在样本期内,内向外商直接投资(IFDI)和对外直接投资(OFDI)显著抑制了GTFP,而两者之间的互动发展水平(DFDI)则显著促进了GTFP。分解 GTFP 后发现,IFDI 或 OFDI 对绿色技术变革(GTC)有明显的促进作用,但对绿色技术效率变革(GEC)有抑制作用,而 DFDI 对 GTC 或 GEC 有促进作用。进一步研究还发现,对外直接投资在长期内可以有效削弱抑制效应;IFDI、OFDI、DFDI对GTFP或GEC的影响方向相同,仅在显著水平上表现出异质性,而在不同类型的制造业中,它们对GTC的影响具有不确定性。制造业结构越合理,对外直接投资、对外直接投资和外商直接投资对GTFP的促进作用越显著。
