Abstract Background: Regional Development (RD) allows countries to balance regional differences by providing economic and social benefits to communities. This research highlights the importance of logistics activities to regional social development, and a framework to assess these connections is proposed. Objectives: How to boost regional socioeconomic development through logistics. Methods/Approach: The contributions of logistics to socioeconomic development are analysed based on the previous research, and the case of the Alto Minho (AM) region in Portugal was used to illustrate the connection between logistics and regional development. Results showed that logistics had created jobs, increased company turnover and exports, and increased GDP growth in several regions. For the AM region, results indicate that many companies are operating in this area, contributing to supporting municipalities to reduce regional disparities. Conclusions: A framework for assessing regional logistics performance is proposed together with several logistics performance indicators. This approach is essential for future developments integrating logistics into socioeconomic development.
背景:区域发展(RD)允许国家通过为社区提供经济和社会利益来平衡区域差异。本研究强调了物流活动对区域社会发展的重要性,并提出了一个评估这些联系的框架。目标:如何通过物流促进区域社会经济发展。方法/途径:物流对社会经济发展的贡献是基于之前的研究进行分析,并在葡萄牙的上米尼奥(AM)地区的情况下,用来说明物流和区域发展之间的联系。结果显示,在一些地区,物流创造了就业机会,增加了公司营业额和出口,并提高了GDP增长。对于AM地区,结果表明许多公司在该地区开展业务,有助于支持市政当局减少区域差距。结论:提出了一个区域物流绩效评估框架,并结合了几个物流绩效指标。这种方法对于将物流融入社会经济发展的未来发展至关重要。

Abstract Background: This paper presents a machine learning approach to forecast Croatia’s international bilateral trade. Objectives: The goal of this paper is to evaluate the performance of machine learning algorithms in predicting international bilateral trade flows related to imports and exports in the case of Croatia. Methods/Approach: The dataset on Croatian bilateral trade with over 180 countries worldwide from 2001 to 2019 is assembled using main variables from the gravity trade model. To forecast values of Croatian bilateral exports and imports for a horizon of one year (the year 2020), machine learning algorithms (Gaussian processes, Linear regression, and Multilayer perceptron) have been used. Each forecasting algorithm is evaluated by calculating mean absolute percentage errors (MAPE). Results: It was found that machine learning algorithms have a very good predicting ability in forecasting Croatian bilateral trade, with neural network Multilayer perceptron having the best performance among the other machine learning algorithms. Conclusions Main findings from this paper can be important for economic policymakers and other subjects in this field of research. Timely information about the changes in trends and projections of future trade flows can significantly affect decision-making related to international bilateral trade flows.
摘要背景:本文提出了一种机器学习方法来预测克罗地亚的国际双边贸易。目的:本文的目标是评估机器学习算法在预测克罗地亚情况下与进出口有关的国际双边贸易流量方面的性能。方法/方法:利用重力贸易模型中的主要变量,对2001年至2019年克罗地亚与全球180多个国家的双边贸易数据集进行了汇总。为了预测克罗地亚一年(2020年)的双边进出口价值,使用了机器学习算法(高斯过程、线性回归和多层感知器)。通过计算平均绝对百分比误差(MAPE)来评估每种预测算法。结果:发现机器学习算法在预测克罗地亚双边贸易方面具有很好的预测能力,其中神经网络多层感知器在其他机器学习算法中表现最好。本文的主要发现对经济政策制定者和该领域的其他研究对象具有重要意义。关于未来贸易流量趋势变化和预测的及时信息可以对与国际双边贸易流量有关的决策产生重大影响。

Abstract Background: This paper focuses on activities related to Customer Orders Management withing an auto components plant in the Automotive Industry. The main challenge was highlighted: customers don’t always regard the flexibility rules agreed with the company. Hence, planners must decide if variation in ordered quantity can be accepted in the forecast period or if adjusting is necessary. Objectives: The purpose was not only to streamline the decision-making process in the planning team but also to provide essential tools for the execution of their daily tasks – a visual and interactive dashboard to assess whether variations in customer orders were within the limits agreed with the company. Methods/Approach: Following Lean information management and business intelligence principles, a thorough process analysis was carried out, centralized and standardized reports were created that served as databases, and the dashboard was developed. Results: The proposed tool allowed reductions from 3,5h per week, spent mainly on collecting data, calculating variations, and selecting and adjusting the flexibility limits, to 0,2h a day per planner. Conclusions: Besides streamlining planners’ daily activities, main contributions regard the promotion of digital transformation, data-driven decision-making, and an automated record of customer order variations that could easily be adapted to suppliers.
摘要背景:本文主要研究汽车工业中某汽车零部件厂的客户订单管理相关活动。主要的挑战是:客户并不总是遵守与公司商定的灵活性规则。因此,计划人员必须决定在预测期内订购数量的变化是否可以接受,或者是否需要进行调整。目标:目的不仅是为了简化计划团队的决策过程,而且还为他们执行日常任务提供必要的工具——一个可视化的交互式仪表板,用于评估客户订单的变化是否在公司同意的范围内。方法/途径:遵循精益信息管理和商业智能的原则,进行深入的流程分析,创建集中标准化的报告作为数据库,并开发仪表板。结果:建议的工具可以将每周花费在收集数据、计算变化、选择和调整灵活性限制上的3.5小时减少到每个计划者每天0.2小时。结论:除了简化计划人员的日常活动外,主要贡献还包括促进数字化转型、数据驱动决策以及客户订单变化的自动化记录,这些记录可以很容易地适应供应商。

Abstract Background: Circular Economy has been considered one of the most powerful principles of modern society. The concerns about increasing resource consumption have forced governments and companies to look at the circular models as a hedge against resource scarcity and an engine for innovation and growth. Objectives: This research aims to bring together the Circular Economy and the consumer’s perspective to perceive the impact of its choices on CE initiatives. Methods/Approach: A survey was conducted considering the consumer’s engagement with the circular economy concepts. Results: The results pointed out the awareness and willingness of consumers for the transition from the linear to the circular production model, providing an added value to consumers for reducing environmental impacts. Conclusions: Consumers’ behaviour can have a forefront role in building a guide with best practices to be considered by companies, designers, and consumers on implementing initiatives in the field of Circular Economy.

Abstract Background: E-commerce has emerged as a good response to the pandemic of COVID-19. However, the costs of providing a service, which includes a driver and a vehicle, in a regular vehicle that can transport goods that need positive cold (0° to 5°C) are very high. Objectives: This paper aims to investigate how a big Portuguese retailer company can reduce its dependence on refrigerated vehicles, simplifying operations and reducing the costs of transporting positive and negative cold food. Methods/Approach: This research was carried out in a food retailer Portuguese company, more precisely in a Dark Store dedicated to the online channel. The study was developed based on the AS-IS/TO-BE process analysis methodology, starting with the analysis of the current situation, giving rise to the so-called AS-IS model. Results: It was possible to reduce costs associated with transporting positive cold goods. As a result, there are 30% fewer costs associated with order transportation. With an additional 10% in space optimization with the gain of space within the galley of each vehicle. Conclusions: The costs of transporting positive and negative cold foods were decreased, and substituting vehicles with room temperature transport reduced the need for refrigerated vehicles.
背景:电子商务作为应对新冠肺炎疫情的一种良好方式应运而生。然而,提供一项服务(包括司机和车辆)的成本非常高,因为普通车辆可以运输需要正冷(0°C至5°C)的货物。目的:本文旨在调查一家大型葡萄牙零售商公司如何减少对冷藏车的依赖,简化操作,降低运输正负冷食品的成本。方法/途径:本研究是在一家葡萄牙食品零售商公司进行的,更准确地说,是在一家致力于在线渠道的暗店。本研究基于AS-IS/ be - to - be流程分析方法,从现状分析开始,产生所谓的AS-IS模型。结果:有可能降低与运输阳性冷货物相关的成本。因此,与订单运输相关的成本减少了30%。在每辆车的厨房内增加10%的空间优化。结论:正冷和负冷食品的运输成本降低,以室温运输替代车辆减少了对冷藏车辆的需求。

Conflict and Corporate Social Responsibility in Duopoly 双头垄断中的冲突与企业社会责任
IF 1.5 Q2 Economics, Econometrics and Finance Pub Date : 2022-10-01 DOI: 10.2478/bsrj-2022-0023

Abstract Background: Recent scientific research explains corporate social responsibility as an economic activity. This paper interprets social responsibility as a means of power to increase firms’ market share in a duopoly. Objectives: This paper analyses the duopoly model in which firms decide on optimal social investments and production in two phases. The basic research question is how the significance of the conflict affects social investments, market shares, production quantities, profits, and social welfare. Methods / Approach: Conflict technology is described by contest success functions determining market shares. Game theory, optimization, and comparative statics are used in the analysis. Results: The conditions of equilibrium existence and its characteristics are described. Conflict adversely affects the profit of the inefficient firm while it favourably affects social welfare. Conflict’s impact on an efficient firm’s profit depends on the marginal cost difference. Conclusions: If there is no significant cost difference, it is more favourable for firms not to invest in socially responsible activities by agreement, which hurts social welfare. When marginal cost difference is significant, corporate social responsibility increases an efficient firm’s profit, positively impacting social welfare.
背景:近年来的科学研究将企业社会责任解释为一种经济活动。本文将社会责任解释为双头垄断中企业增加市场份额的一种权力手段。目的:分析企业在两个阶段决定最优社会投资和生产的双寡头模型。基本研究问题是冲突的重要性如何影响社会投资、市场份额、生产数量、利润和社会福利。方法/途径:用决定市场份额的竞赛成功函数来描述冲突技术。博弈论,优化和比较静力学在分析中使用。结果:描述了平衡存在的条件及其特征。冲突对无效率企业的利润产生不利影响,而对社会福利产生有利影响。冲突对高效企业利润的影响取决于边际成本差异。结论:在成本差异不显著的情况下,企业更倾向于协议不投资社会责任活动,从而损害社会福利。当边际成本差异显著时,企业社会责任增加了效率企业的利润,正向影响社会福利。

Abstract Background: In making investment decisions, asset risk and return are two crucial criteria on which investors base their decision. Objectives: This paper provides risk and return analysis and compares different traditional and alternative investments with special emphasis on the COVID-19 crisis. Assets included in the analysis are stocks, bonds, commodities, real estate, foreign exchange, cryptocurrencies, renewable energy sources, gold, and oil. Methods/Approach: The risk measures of standard deviation, Value at Risk (VaR), Conditional Value at Risk (CVaR), and Sharpe ratio are used to compare the representatives of each asset class. Results: The crisis had the highest impact on the risk of crude oil, renewable energy sources, real estate, and stocks, a slightly lower impact on the risk of commodities and gold, and a very low impact on the risk of bonds, foreign exchange, and cryptocurrencies. The order of assets regarding earning potential during the crisis, compared to the period before the crisis, changed significantly for commodities in a positive way and for gold and bonds in a negative way. Conclusions: This research shows that stocks won against all other assets, including gold and cryptocurrencies, during the COVID-19 crisis. The good features of a new alternative investment – renewable energy sources – with excellent earning potential are shown.
摘要背景:在进行投资决策时,资产风险和收益是投资者决策的两个重要依据。目的:本文提供风险和回报分析,并比较不同的传统和另类投资,特别强调COVID-19危机。分析中包括的资产包括股票、债券、大宗商品、房地产、外汇、加密货币、可再生能源、黄金和石油。方法/途径:采用标准差、风险价值(VaR)、条件风险价值(CVaR)和夏普比率等风险指标对各资产类别的代表进行比较。结果:此次危机对原油、可再生能源、房地产和股票风险的影响最大,对大宗商品和黄金风险的影响略低,对债券、外汇和加密货币风险的影响很低。与危机前相比,危机期间与盈利潜力相关的资产排序在大宗商品方面发生了显著的积极变化,而黄金和债券方面则发生了显著的消极变化。结论:这项研究表明,在2019冠状病毒病危机期间,股票赢了所有其他资产,包括黄金和加密货币。一种新的替代投资——可再生能源——具有良好的盈利潜力。

Conclusions: This research shows that stocks won against all other assets, including gold and cryptocurrencies, during the COVID-19 crisis. The good features of a new alternative investment – renewable energy sources – with excellent earning potential are shown.","PeriodicalId":43772,"journal":{"name":"Business Systems Research Journal","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77272417","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}

Abstract Background: People with visual impairment or blindness (PWVIB) face many barriers related to employment. Although literature explores employers’ concerns regarding the employment of PWVIB, stating the concern and developing a solution are different. Objectives: Employers’ solutions to concerns regarding hiring PWVIB have not been surveyed. This study addresses the gap by surveying employers to determine practical solutions and developing the Solutions for Improving Employment of People with Visual Disabilities (SIEPVD) model. Methods: We employed a mixed-method design based on the 975 completed surveys from employers with hiring authority. We also identified and tagged major themes and developed an empirical model. Structural Equation Modelling (SEM) was employed to test the model’s goodness of fit. Results: Findings highlight the need for evidence of job capabilities such as financial incentives, information provision, and adequate job vacancies. Evidence or financial incentives directly and positively affect employers’ attitudes toward hiring PWVIB. Financial incentives also mediate information provision and job match with employers’ attitudes toward hiring PWVIB. Conclusions: This is the first study to perform employers’ integration by creating solutions to increase PWVIB’s employment rate. Results may help PWVIB in its employment efforts. Thus, the approach when applying for jobs or attending interviews should be reviewed. Practical contributions are discussed.
背景:视障或失明人士(PWVIB)面临着许多与就业相关的障碍。虽然文献探讨了雇主对PWVIB就业的关注,但陈述关注和制定解决方案是不同的。目的:雇主对雇用PWVIB问题的解决方案尚未进行调查。本研究通过调查雇主来确定切实可行的解决方案,并开发了改善视力障碍者就业的解决方案(SIEPVD)模型,从而解决了这一差距。方法:我们采用混合方法设计,基于975份已完成的调查,这些调查来自有雇佣权的雇主。我们还确定并标记了主要主题,并开发了一个实证模型。采用结构方程模型(SEM)对模型的拟合优度进行检验。结果:研究结果强调了工作能力证据的必要性,如财政激励、信息提供和充足的职位空缺。证据或财政激励直接和积极地影响雇主对雇用PWVIB的态度。财务激励也会调节信息提供和职位匹配与雇主对雇用PWVIB的态度。结论:这是第一个通过创建解决方案来提高PWVIB就业率的雇主整合研究。研究结果可能有助于工行在就业方面的努力。因此,申请工作或参加面试的方法应该重新审视。讨论了实际贡献。

Abstract Background: Innovation policy supports innovation in companies, as it is crucial for economic, social and environmental development. Objectives: The research aims to verify whether companies that have received public support for innovation are experiencing turnover growth. Methods/Approach: The research is carried out on the example of the Czech Innovation Programme, and the analysis included 276 projects in the manufacturing industry. The study compares the turnover of enterprises one year before receiving the aid and two years after the granting. The analysis is performed regarding the size of companies, industries and regions. Results: When the companies are assessed at the median level, the largest turnover growth was found in the category of small enterprises. Regarding industry, the largest increase was recorded in NACE sections 22, 27, 26, 29 and 30. The lowest increase in turnover was recorded for enterprises in sections 21, 23, 24 and 28. Differences in turnover growth were also observed across regions. Conclusions: Providing support for innovation contributes to the growth of turnover. A larger share of public aid should be allocated to the category of small and medium-sized enterprises and knowledge-intensive industries.
