This study examined the relationship between technological absorptive capacity and the business performance of small and medium-sized enterprises (SMEs), as well as the mediating effect of e-business innovation. Based on data obtained from 179 sunflower oil-processing SMEs in Tanzania and analyzed using partial least squares structural equation modeling, the study established that technological absorptive capacity influences business performance. Further, e-business innovation partially mediates the relationship between technological absorptive capacity and business performance. These findings suggest that technological absorptive capacity indirectly influences SME business performance through e-business innovation. On the other hand, findings from the multigroup analysis revealed insignificant differences in the hypothesized relationships between samples from Dodoma and Singida regions, with greater effects observed in Dodoma than in Singida for most of the relationships. The mediating effect of e-business innovation is more profound in the Dodoma sample than in the Singida sample. This study provides important empirical evidence of the role of technological absorptive capacity and e-business innovation in enhancing SME business performance. Additionally, evidence from cross-regional comparisons is crucial for examining differences in business performance among SMEs operating in the country. This study has some implications for business managers, governments, policymakers, and academics.
本研究考察了中小企业技术吸收能力与企业经营绩效的关系,以及电子商务创新的中介效应。基于坦桑尼亚179家葵花籽油加工中小企业的数据,采用偏最小二乘结构方程模型进行分析,得出技术吸收能力对企业绩效的影响。此外,电子商务创新部分中介了技术吸收能力与企业绩效之间的关系。研究结果表明,技术吸收能力通过电子商务创新间接影响中小企业经营绩效。另一方面,多组分析的结果显示,Dodoma和Singida地区样本之间的假设关系差异不显著,在大多数关系中,Dodoma地区的影响大于Singida地区。电子商务创新的中介效应在Dodoma样本中比在Singida样本中更为深刻。本研究为技术吸收能力和电子商务创新对中小企业经营绩效提升的作用提供了重要的实证证据。此外,来自跨区域比较的证据对于检查在该国经营的中小企业之间的业务绩效差异至关重要。本研究对企业管理者、政府、政策制定者和学者具有一定的启示意义。

The global economy has undergone a digital transformation that is now essential for sustainable business success, with COVID-19 significantly accelerating this trend. Organizations have been compelled to adopt digital technologies to remain competitive in an increasingly demanding market. In Spain, the social economy sector has also embraced digitalization, supported by specific funding; however, social economy enterprises often struggle due to limited resources, hindering their ability to fully leverage digital advancements.
The social economy includes organizations focused on social rather than financial objectives, characterized by democratic governance and efforts to address local social and economic challenges. This sector has seen the rise of social entrepreneurship initiatives aimed at tackling societal issues through sustainable and responsible business practices. Social entrepreneurship thus combines social and economic value creation, supporting social inclusion and sustainable development.
This paper aims to assess the current literature on sustainable digitalization, the social economy, and social entrepreneurship through a bibliometric study, identifying key trends and areas of interest. Furthermore, it examines how digitalization is integrated within the business models of social economy enterprises. The study finds that while digitalization promotes innovation and sustainability in the social economy, organizations face challenges like limited resources and digital skills gaps. This hinders competitiveness. The research calls for tailored policies to address sector-specific needs and suggests further exploration of emerging technologies, such as artificial intelligence and big data, insocial enterprises.
全球经济经历了数字化转型,这对可持续的商业成功至关重要,而2019冠状病毒病显著加速了这一趋势。为了在日益苛刻的市场中保持竞争力,组织不得不采用数字技术。在西班牙,社会经济部门也接受了数字化,并得到了专项资金的支持;然而,由于资源有限,社会经济企业往往举步维艰,阻碍了他们充分利用数字化进步的能力。社会经济包括专注于社会而非财务目标的组织,其特点是民主治理和努力解决当地的社会和经济挑战。这一领域出现了旨在通过可持续和负责任的商业实践解决社会问题的社会创业倡议。因此,社会企业家精神结合了社会和经济价值创造,支持社会包容和可持续发展。本文旨在通过文献计量学研究评估当前关于可持续数字化、社会经济和社会企业家精神的文献,确定关键趋势和感兴趣的领域。此外,它还研究了如何将数字化整合到社会经济企业的商业模式中。研究发现,虽然数字化促进了社会经济的创新和可持续性,但组织面临着资源有限和数字技能差距等挑战。这阻碍了竞争力。该研究呼吁制定量身定制的政策,以满足特定行业的需求,并建议在社会企业中进一步探索人工智能和大数据等新兴技术。

The objective of this study is to analyse the correlation between Bitcoin and altcoins in the post-covid world and take advantage of this possible relationship to design investment strategies on Bitcoin based on the evolution of altcoins using Artificial Intelligence (AI) models.
The sample of daily observations covers from January 2020 to February 2023, and the regressions performed between altcoins and Bitcoin are positive and 99 % significant, except for Dogecoin, which has a correlation with Bitcoin.
If we add a lag, the estimated parameters are still 95 % significant, except for Dogecoin, so we can assume that the return of altcoins anticipates the evolution of Bitcoin.
We train an artificial intelligence model in which the predictors are the observed daily return in altcoins and the target to predict is next day trend of Bitcoin (up or down). We use decision tree algorithms (J48), random forest and naive bayes, but in a retrospective cross-sectional validation with 10 sample partitions we obtain a poor predictive capacity of only a 51 % success rate in the best of cases.
Therefore, despite the evident correlation between predictors and the objective variable, we should not implement this investment strategy.
本研究的目的是分析后科维德世界中比特币与另类币之间的相关性,并利用这种可能的关系,使用人工智能(AI)模型,根据另类币的演变设计比特币投资策略。每日观察样本涵盖 2020 年 1 月至 2023 年 2 月,除 Dogecoin 与比特币有相关性外,另类币与比特币之间的回归结果均为正值,且 99 % 显著。如果我们增加一个滞后期,除了 Dogecoin 外,估计参数仍有 95% 的显著性,因此我们可以认为,另类币的回报率预示着比特币的变化。我们训练了一个人工智能模型,其中预测因子是观察到的另类币每日回报率,预测目标是比特币的次日趋势(上涨或下跌)。我们使用了决策树算法(J48)、随机森林算法和天真贝叶斯算法,但在 10 个样本分区的回顾性横截面验证中,我们得到的预测能力很差,在最好的情况下成功率仅为 51%。

Enhancing energy efficiency through sustainable technological progress is imperative for pursuing sustainable development, particularly in developing countries where economic growth is strongly linked to higher energy consumption. In Tunisia, an open and developing economy, fossil energy consumption can be reduced without compromising economic growth by focusing on diminishing energy intensity. This study investigates the effects of technological progress on the overall energy intensity in Tunisia from 1980 to 2019, examining the role that technological advancements may play in attaining sustainable development goals. This study is based on a growth accounting model that uses time-series analysis and a cointegration estimation approach. Our empirical results suggest the presence of a long-term connection between the variables. The attainment of enhanced energy efficiency is contingent on the growth rate of technological progress, which should exceed capital and labor productivity. The results reveal that the net impact of technological advancements is estimated at -0.0163, which signifies that aggregate energy intensity tends to decrease by an annual average of 1.63% in the long term. These findings underscore the need for developing economies to restructure their energy policies and support sustainable technological initiatives and green entrepreneurship. Developing countries can reduce their energy intensity while boosting their economic growth by fostering technological innovation. This study demonstrates how technological progress and green entrepreneurship can be leveraged to enhance energy efficiency and drive sustainable development in developing nations.
通过可持续的技术进步提高能源效率是实现可持续发展的当务之急,尤其是在经济增长与能源消耗增加密切相关的发展中国家。突尼斯是一个开放的发展中经济体,在不影响经济增长的情况下,可以通过降低能源强度来减少化石能源消耗。本研究调查了 1980 年至 2019 年技术进步对突尼斯总体能源强度的影响,探讨了技术进步在实现可持续发展目标方面可能发挥的作用。本研究基于增长核算模型,采用时间序列分析和协整估计方法。我们的实证结果表明,变量之间存在长期联系。提高能源效率取决于技术进步的增长率,而技术进步的增长率应超过资本和劳动生产率。结果表明,技术进步的净影响估计为-0.0163,这意味着从长期来看,总能源强度趋向于年均下降 1.63%。这些研究结果表明,发展中经济体需要调整能源政策,支持可持续技术倡议和绿色创业。发展中国家可以通过促进技术创新,在降低能源强度的同时推动经济增长。本研究展示了如何利用技术进步和绿色创业来提高能源效率,推动发展中国家的可持续发展。

AI-induced job impact: Complementary or substitution? Empirical insights and sustainable technology considerations 人工智能对就业的影响:互补还是替代?经验见解和可持续技术考虑因素
Pub Date : 2024-10-02 DOI: 10.1016/j.stae.2024.100085

This study utilizes 3,682 full-time workers to examine perceptions of AI-induced job displacement risk and evaluate AI's potential complementary effects on labor. By distinguishing between these variables, the research identifies which worker characteristics and industries are most affected by AI. Employing an extended ordered probit model, the results show that those with higher perceived risks are mainly female, older, and more educated. Workers with frequent internet usage and remote work are more concerned about AI-induced job risks. Sector-wise, entry-level employees perceive the least risk, whereas manufacturing professionals and senior service sector employees are more apprehensive. Contrary to the mainstream assumption that AI causes unemployment, this study identifies a potential complementary effect on job tasks, suggesting that AI can enhance and support human labor rather than replace it. This inference is based on observed worker perceptions and the increased use of AI tools in tasks that complement human skills. Moreover, AI's integration contributes to sustainable practices and entrepreneurial opportunities, enhancing business innovation and environmental efficiency. Workers increasingly view AI as a value-added element in their jobs rather than a threat, particularly in sectors focusing on sustainable development and green technologies.
本研究利用 3,682 名全职工人,考察他们对人工智能引发的工作转移风险的看法,并评估人工智能对劳动力的潜在补充效应。通过区分这些变量,研究确定了哪些工人特征和行业受人工智能的影响最大。利用扩展的有序概率模型,研究结果表明,感知风险较高的工人主要是女性、年龄较大、受教育程度较高。经常使用互联网和从事远程工作的工人更担心人工智能引发的工作风险。从行业来看,入门级员工感知到的风险最小,而制造业专业人员和高级服务业员工则更为担忧。与 "人工智能会导致失业 "这一主流假设相反,本研究发现了人工智能对工作任务的潜在补充效应,表明人工智能可以增强和支持人类劳动,而不是取代人类劳动。这一推论的依据是观察到的工人看法,以及在补充人类技能的任务中越来越多地使用人工智能工具。此外,人工智能的整合有助于可持续实践和创业机会,提高业务创新和环境效率。工人们越来越多地将人工智能视为工作中的增值要素,而不是威胁,尤其是在注重可持续发展和绿色技术的部门。

Digitalization is emerging as a broader socio-technical transformation affecting businesses of all types. The paradigm shifts in digital technology have mandated new mindsets and approaches to managerial, leadership, and entrepreneurial competitiveness in organizations. Human capital with the ability to convey digital knowledge and strategies is regarded as a crucial resource for digital transformations (DT) in organizations. In fact, the development of relevant technological and digital competencies (DCs) is regarded as the biggest obstacle to DT in non-profit organizations (NPOs) as well. However, the growth of literature in this direction has been fragmented by the lack of any formal integration of DCs. The current study is formulated with the primary goal of exploring the digital competency requirements of NPOs. A systematic literature review protocol adhering to PRISMA guidelines was undertaken to synthesize the initial draft of DCs. Subsequently, a modified two-round Delphi survey with a panel of 25 experts was used to rate the competencies quantitatively. The analysis followed the prescribed Delphi principles to determine the results' validity and reliability. As a result, a comprehensive set of eighteen competencies was generated and categorized into three areas (‘digital leadership’, ‘personnel and organizational’, and ‘technical’ competencies). While filling an important void in the literature, the study's findings lay the groundwork for a digital transformation education, learning, and development agenda in non-profits.
数字化正在成为影响各类企业的更广泛的社会技术变革。数字技术的范式转变要求各组织在管理、领导力和企业竞争力方面采用新的思维和方法。有能力传递数字知识和战略的人力资本被视为组织数字转型(DT)的关键资源。事实上,相关技术和数字化能力(DCs)的发展也被视为非营利组织(NPOs)数字化转型的最大障碍。然而,由于缺乏对数字能力的正式整合,这方面的文献发展一直比较零散。本研究的首要目标是探索非营利组织的数字化能力要求。研究采用了符合 PRISMA 准则的系统性文献综述方案,对 DCs 初稿进行了归纳。随后,由 25 位专家组成的小组进行了经过修改的两轮德尔菲调查,对能力进行量化评分。分析遵循规定的德尔菲原则,以确定结果的有效性和可靠性。结果,产生了一套包含 18 种能力的综合能力,并将其分为三个领域("数字领导力"、"人事和组织 "以及 "技术 "能力)。在填补文献空白的同时,研究结果也为非营利组织的数字化转型教育、学习和发展议程奠定了基础。

Waste management is now a major global concern. Therefore, the circular economy (CE) and sustainable technology have become the necessary means of achieving sustainable business development. In this study, we conduct an analysis of the waste recovery sector in Spain to determine whether the most innovative and socially aware companies complied with sustainable development goal (SDG) 5 (gender equality) and SDG 8 (decent work and growth) during the period 2019–2021 (pre-Coronavirus Disease 2019, (pre-COVID-19), during COVID-19, and post-COVID-19). To this end, based on factors comprising economic and financial variables, the companies were grouped via a cluster analysis using the k-means method; they were linked to the SDGs (5 and 8) in order to determine the compliance of this sector. The results indicate that the technological transformations carried out by the waste valorization companies were reflected in their financial performance, with an increase in revenues of 61 % between 2019 and 2021; all clusters complied with SDG 8. However, despite promoting business transformation, social change, sustainable technology, and CE, these companies are far from compliant with SDG 5; indeed, a setback in social development was observed, with a significant decline in the number of women in positions of power after COVID-19. This therefore constitutes one of the greatest challenges for companies in this sector.

废物管理现已成为全球关注的主要问题。因此,循环经济(CE)和可持续技术已成为实现企业可持续发展的必要手段。在本研究中,我们对西班牙的废物回收行业进行了分析,以确定最具创新性和社会意识的公司在 2019-2021 年期间(2019 年科罗纳病毒病前、(COVID-19 前)、COVID-19 期间和 COVID-19 后)是否符合可持续发展目标 (SDG) 5(性别平等)和 SDG 8(体面工作和增长)。为此,根据包括经济和金融变量在内的各种因素,利用 K-means 方法通过聚类分析对这些公司进行了分组,并将它们与可持续发展目标(5 和 8)联系起来,以确定该部门的合规情况。结果表明,垃圾处理公司进行的技术改造反映在其财务业绩上,在 2019 年至 2021 年期间,收入增加了 61%;所有聚类都符合可持续发展目标 8。然而,尽管这些公司促进了业务转型、社会变革、可持续技术和行政首长协调会,但却远未实现可持续发展目标 5;事实上,社会发展出现了倒退,在 COVID-19 之后,担任要职的妇女人数大幅减少。因此,这也是该行业公司面临的最大挑战之一。

This paper provides a bibliometric overview of the interaction between environmental education and the growth of sustainable entrepreneurship. Using VOSViewer and the R programming language, we found 849 reference studies for investigation while browsing English-language articles from esteemed publications and conferences recorded in the Scopus databases. Our analysis revealed an exponential increase in scholarly publications on the topic, therefore highlighting its development as a current focus of study. Our bibliometric study reveals a major knowledge gaps despite this increase: knowledge of the successful integration strategies of environmental education into sustainable entrepreneurship practices and policies at different levels (local, national, and global). Moreover, thorough research on how these interactions affect environmental awareness across several populations and the accomplishment of sustainable development goals (SDGs) is lacking. Therefore, our study aims to close this important void by offering a thorough review of the present situation of research, pointing out the best journals, countries, and authors leading in this field, and suggesting future directions to improve the synergy between environmental education and sustainable development. Policies, courses, and projects aiming at a more sustainable future depend on this input in setting their direction.

本文通过文献计量学概述了环境教育与可持续创业发展之间的互动关系。我们使用 VOSViewer 和 R 编程语言,浏览了 Scopus 数据库中记录的著名出版物和会议的英文文章,找到了 849 项参考研究。我们的分析表明,有关该主题的学术出版物呈指数级增长,因此凸显了其作为当前研究重点的发展态势。我们的文献计量学研究揭示了一个重大的知识缺口,尽管这一增长:在不同层面(地方、国家和全球),环境教育与可持续创业实践和政策的成功整合战略的知识。此外,对于这些互动如何影响不同人群的环境意识以及可持续发展目标(SDGs)的实现,也缺乏深入研究。因此,我们的研究旨在填补这一重要空白,对研究现状进行全面回顾,指出该领域的最佳期刊、国家和领先作者,并提出改善环境教育与可持续发展之间协同作用的未来方向。旨在实现更可持续未来的政策、课程和项目在确定方向时都有赖于这方面的投入。
