Public servants play an important role as guardians, guarantors, and promoters of the regime values who are in frequent contact with the citizens. Having that in mind, it is of high importance to understand their behaviour and attitudes on legal changes, perceived red tape and job stress. The aim of this paper is, therefore, twofold: firstly, to explore the influence of red tape and perceived red tape on public procurement officers’ (PPOs) and managers’ (PPMs) perception of the new Public Procurement Law in terms of its benefits to public procurement process and to their jobs and job stress, and secondly, to explore the differences between PPOs and PPMs regarding the examined statements. To answer the first question, we proposed a conceptual model which was tested using structural equation modelling (SEM), while to answer the second question we used the Mann-Whitney test. Both analyses were done using the data collected from 115 PPOs and PPMs in Serbia. The results show that PPOs and PPMs share similar attitudes regarding the existence of red tape, perceived job stress, and the influence they expect the new legislation will have on their jobs. Their expectations of the new legislation as well as their perception of job stress are found to be partially influenced by red tape. As PPOs are not that convinced that the new law will improve their job, it may be concluded that the changes the new law will bring are not substantial enough.
公务员是经常与国民接触的政权价值的守护者、保证人和推动者。考虑到这一点,了解他们对法律变化、所谓的繁文缛节和工作压力的行为和态度是非常重要的。因此,本文的目的是双重的:首先,探讨繁文缛节和感知的繁文缛节对公共采购官员(PPOs)和管理人员(PPMs)对新《公共采购法》的看法的影响,就其对公共采购过程的好处以及对他们的工作和工作压力而言,其次,探讨PPOs和PPMs之间在审查陈述方面的差异。为了回答第一个问题,我们提出了一个概念模型,并使用结构方程模型(SEM)进行了测试,而为了回答第二个问题,我们使用了曼-惠特尼测试。这两项分析都是利用从塞尔维亚115个ppo和ppm收集的数据完成的。结果显示,公私合营者和公私合营者对繁文缛节的存在、感知到的工作压力以及他们预期新立法对他们工作的影响的态度相似。调查发现,他们对新法规的期望以及对工作压力的感知在一定程度上受到繁文缛节的影响。由于私人律师不太相信新法会改善他们的工作,因此可以得出结论,新法带来的变化不够大。

Blockchain technology has the potential to reshape the conventional ways of processes and transactions on digital platforms. Much of the attention surrounding blockchain is mainly focused on the technical and organizational aspects. Comparatively, little effort has been targeted towards understanding the attitudinal issues in blockchain adoption. This study aims to explore the role of attitudinal forms behind the intended timing of IT professionals’ blockchain adoption, with an emphasis on the differences between the public and private sectors. A survey method was used where the data was collected from 208 IT professionals from public and private sector establishments in order to investigate how the different attitudes of the participants as well as the differences in their work sectors affect their intention to adopt blockchain. The data collected was analysed with ordinal logistic regression and the results indicate that the participants’ affective, normative and pessimistic attitudes have a significant effect on the timing of blockchain adoption, and that these effects show differences among the IT professionals from the public and private sector. The findings are believed to provide valuable information to researchers and strategists in forecasting the future evolution of the blockchain technology in terms of individual utilization. The results also will provide feedback to managers of different sectors in making decisions regarding blockchain adoption, developers of blockchain services, as well as individuals who are interested in using blockchain.
区块链技术有可能重塑数字平台上的传统流程和交易方式。围绕区块链的大部分关注主要集中在技术和组织方面。相比之下,很少有人致力于理解区块链采用中的态度问题。本研究旨在探讨态度形式在IT专业人员采用区块链的预期时间背后的作用,重点是公共部门和私营部门之间的差异。采用调查方法,从公共和私营部门机构的208名IT专业人员中收集数据,以调查参与者的不同态度以及他们工作部门的差异如何影响他们采用区块链的意图。收集的数据用有序逻辑回归进行了分析,结果表明,参与者的情感、规范和悲观态度对区块链采用的时间有显著影响,这些影响显示了公共和私营部门IT专业人员之间的差异。这些发现被认为为研究人员和战略家预测区块链技术在个人使用方面的未来发展提供了有价值的信息。结果还将为不同部门的管理人员提供反馈,以制定有关区块链采用的决策,区块链服务的开发人员以及对使用区块链感兴趣的个人。

The massive spread of the COVID-19 outbreak has widely disrupted business activities around the world. In such a context, more manufacturing enterprises have to turn to online sales to restore sales and workforce. However, the actual effects of above relationships are still unknown. The aim of this study is to analyze whether and how online sales affect sales and workforce recovery from COVID-19. Meanwhile, we deeply explore the mediating effect of cash flow adequacy and the moderating effect of firm size. Drawing from a cross-country survey with 2714 manufacturing enterprises during the COVID-19 pandemic and controlling for self-selection bias, we find an inverted U-shaped effect of online sales on sales and workforce recovery. Online sales also exert an inverted U-shaped effect on cash flow adequacy, whereas this effect is weaker for small and medium enterprises (SMEs). Furthermore, cash flow adequacy positively facilitates sales and workforce recovery, indicating the role of cash flow adequacy in partially mediating the relationship between online sales and recovery. In addition, we confirm that firm size moderates the indirect effect of online sales on sales and workforce recovery through cash flow adequacy. This study not only expands e-commerce and emergency management research domain and enriches the results of related research, but also provides management implications for the recovery of manufacturing enterprises from the perspective of online sales during the COVID-19 pandemic.
新冠肺炎疫情大规模蔓延,严重影响了全球经济活动。在这样的背景下,更多的制造企业不得不转向网上销售,以恢复销售和劳动力。然而,上述关系的实际影响尚不清楚。本研究的目的是分析在线销售是否以及如何影响新冠肺炎后的销售和员工恢复。同时,深入探讨了现金流量充足性的中介效应和企业规模的调节效应。在新冠肺炎疫情期间,我们对2714家制造企业进行了跨国调查,并控制了自我选择偏差,我们发现在线销售对销售额和劳动力恢复的影响呈倒u型。网络销售对现金流充足率也有倒u型的影响,而对中小企业的影响较弱。此外,现金流充足率正向促进销售和劳动力恢复,表明现金流充足率在网上销售和恢复之间的关系中起部分中介作用。此外,我们确认公司规模通过现金流充足率调节了在线销售对销售额和劳动力恢复的间接影响。本研究不仅拓展了电子商务和应急管理的研究领域,丰富了相关研究成果,而且从新冠肺炎疫情期间在线销售的角度为制造业企业的复苏提供了管理启示。

In our paper we present the impact of final consumption change on a product by applying the meaning of the autonomous consumption multiplier. Similar to Leontief and Kahn we introduced the multiplier of autonomous consumption, and with it the concept of the influence of change in final consumption on production in the order of a series of subsequent periods. In our analysis, the Slovenian economic investments in the renovation of Slovenian cultural heritage buildings affect the revenue of the Slovenian economy by a multiplier of 2,945. The impact on value added is 1,236. With one million investments in the renovation of Slovene cultural heritage buildings, the revenue of the Slovene economy will increase by more than 2.9 million euros and value added by 1.2 million euros after the adjustment period. The analysed investments will enable employments of 32 employees and the utilization of 3 million euros in fixed assets.
本文通过应用自主消费乘数的含义,提出了最终消费变化对产品的影响。与Leontief和Kahn类似,我们引入了自主消费乘数,并引入了最终消费变化对生产的影响的概念,以一系列后续时期为顺序。在我们的分析中,斯洛文尼亚对斯洛文尼亚文化遗产建筑翻新的经济投资对斯洛文尼亚经济收入的影响乘数为2,945。对增加值的影响为1236。斯洛文尼亚文化遗产建筑翻新投资100万欧元,经过调整期,斯洛文尼亚经济收入将增加290多万欧元,附加值将增加120万欧元。分析的投资将使32名员工的就业和300万欧元的固定资产的利用。

This paper explores how entrepreneurial education and entrepreneurial environment affect entrepreneurial readiness (ER) of students from Science, Technology, Engineering, Mathematics (STEM), and business, i.e., economics and management (E&M) studies. Moreover, it examines how the combination of the aforementioned factors affect the difference in ER between STEM and E&M students. The evaluation is performed on the sample of 595 university students. The results show that two sources of entrepreneurial learning, entrepreneurial experience in the family environment and entrepreneurial education at university, combined with the field of studies represent significant factors that predetermine students’ ER. To be able to reach the highest level of ER, the combination of having entrepreneurial environment and entrepreneurial education is crucial for both E&M and STEM students. However, since E&M students show higher level of ER, the paper emphasises the importance of fostering systemic entrepreneurial education among STEM students.
本文探讨了创业教育和创业环境如何影响科学、技术、工程、数学(STEM)和商业(即经济和管理(E&M)专业学生的创业准备(ER)。此外,本研究探讨上述因素的组合如何影响STEM和E&M学生之间的ER差异。以595名大学生为样本进行评价。研究结果表明,创业学习的两种来源——家庭环境中的创业经历和大学创业教育,结合研究领域,代表了大学生创业认知的显著因素。要达到最高水平的ER,创业环境和创业教育的结合对机电和STEM学生都至关重要。然而,由于机电学生表现出较高的ER水平,本文强调了在STEM学生中培养系统创业教育的重要性。

Economics and engineering have often intertwined, through the sharing of mathematical modeling tools, analogies and the migration of concepts. These processes have contributed to bridging the epistemological gap between the two disciplines and above all they have fueled a contamination that has allowed the advancement of knowledge. However, this exchange has long entered a phase of diminishing returns and is now not sufficient to respond to the growing complexity that is required of science and its methodologies to interpret the real world, increasingly integrated in all its aspects and influenced by clusters of pervasive innovation and technological progress. This urges the establishment of a new "pluralistic alliance" between the different semi-autonomous branches of the two disciplines, to be realized on a scientific platform, understood as a socio-epistemic space that allows for the meeting between scholars aimed at achieving common or similar scientific goals. The article discusses how to institutionalize this platform and highlights the largely incipient state and difficulties that stand in the way of its legitimacy.
通过共享数学建模工具、类比和概念迁移,经济学和工程学经常交织在一起。这些过程有助于弥合两个学科之间的认识论差距,最重要的是,它们助长了一种允许知识进步的污染。然而,这种交流早已进入了收益递减的阶段,现在不足以应对科学及其解释现实世界的方法所要求的日益复杂的情况,科学及其方法在所有方面日益一体化,并受到大量普遍创新和技术进步的影响。这促使在这两个学科的不同半自治分支之间建立一个新的“多元联盟”,在一个科学平台上实现,被理解为一个社会认知空间,允许旨在实现共同或类似科学目标的学者之间的会议。本文讨论了如何将这一平台制度化,并强调了其合法性道路上的初级状态和困难。

This paper proposes an approach to select a market segment portfolio to maximize overall profit.  The study first uses artificial intelligence algorithms to select the market segments with high profitability. The mathematical programming model is then used to identify the most profitable market segment portfolio. The single-objective programming model is used to find the optimal profit for the baseline condition, and a sensitivity analysis is performed to understand the impact of the variable changes on the results. Then, a multi-objective programming model helps to identify the best profit when the evaluated items reach extreme values. A sensitivity analysis is conducted to reveal the impact of the variable changes on the results. The above results are compared with those of the scoring method.  It is found that the artificial intelligence algorithm combined with mathematical programming models can indeed find the market segmentation portfolio with better profits than the conventional methods.

The purpose of the paper is to present how members of cluster organizations perceive their role in the accumulation of technological capability through social learning. The paper presents the results of a qualitative study of four cluster organizations. The theoretical foundation of the study are the communities of practice and the organizational inertia theories. The study indicates that the dynamics of technological capability of cluster organizations’ companies varies regarding three identified communities of practice, namely Participants, Cooperators and Locomotives. The so-called Dead souls (not included in any of the identified communities of practice) did not accumulate technological capability, while the companies classified as Participants increased their technological capability through social learning in cluster organizations provided that the cluster organizations offered comparatively high benefits. Those members of cluster organizations, identified as Cooperators and Locomotives, exhibited relatively high initial technological capability and increased it when the benefits received through social learning in cluster organizations were aligned with their technological trajectories. The study adds to the underdeveloped knowledge of cluster organizations by examining their role in enabling social learning that helps cluster firms accumulate technological capability.
本文的目的是展示集群组织的成员如何通过社会学习来感知他们在技术能力积累中的作用。本文介绍了对四个集群组织进行定性研究的结果。本研究的理论基础是实践共同体理论和组织惯性理论。研究表明,集群组织公司的技术能力动态在三个确定的实践社区(参与者、合作者和火车头)中有所不同。所谓的Dead souls(不包括在任何已确定的实践社区中)没有积累技术能力,而被归类为参与者的公司通过集群组织中的社会学习提高了技术能力,前提是集群组织提供了相对较高的收益。这些集群组织成员(合作者和火车头)表现出相对较高的初始技术能力,当集群组织中通过社会学习获得的利益与他们的技术轨迹一致时,他们的初始技术能力就会提高。本研究通过考察集群组织在促进社会学习(帮助集群企业积累技术能力)中的作用,补充了对集群组织的欠发达知识。

The paper presents the results of a qualitative study of four cluster organizations. The theoretical foundation of the study are the communities of practice and the organizational inertia theories. The study indicates that the dynamics of technological capability of cluster organizations’ companies varies regarding three identified communities of practice, namely Participants, Cooperators and Locomotives. The so-called Dead souls (not included in any of the identified communities of practice) did not accumulate technological capability, while the companies classified as Participants increased their technological capability through social learning in cluster organizations provided that the cluster organizations offered comparatively high benefits. Those members of cluster organizations, identified as Cooperators and Locomotives, exhibited relatively high initial technological capability and increased it when the benefits received through social learning in cluster organizations were aligned with their technological trajectories.

Digital servitization provides radical changes in the offer of products from manufacturing firms. The purpose of this paper is to investigate the impact of digital servitization on manufacturing firm performance and demonstrate the role of technology intensity, product-related services, and digital solutions in different industry sectors. This research collected data from 240 manufacturing firms from the Republic of Serbia under the European manufacturing survey from 2018. Multivariate regression analysis was used to test the impact of product-related services and digital solutions on manufacturing firm performance according to technology intensity.  The findings show that the impact of digital servitization is more significant with the higher technology intensity level of the industry sector. Furthermore, the results show that Data-based services based on Big Data Analysis have the highest impact on manufacturing firm performance in all categories of technology intensity. Moreover, results from the fixed panel regression show production managers which combination of product-related services along with digital solutions make the highest financial performance according to the technology intensity of the firm.
数字化服务化为制造企业提供的产品带来了根本性的变化。本文的目的是研究数字化服务化对制造业企业绩效的影响,并证明技术强度、产品相关服务和数字化解决方案在不同行业中的作用。这项研究收集了2018年以来欧洲制造业调查中来自塞尔维亚共和国240家制造业公司的数据。采用多元回归分析,根据技术强度检验产品相关服务和数字化解决方案对制造企业绩效的影响。研究结果表明,产业部门技术强度越高,数字化服务化的影响越显著。此外,研究结果表明,在所有技术强度类别中,基于大数据分析的基于数据的服务对制造企业绩效的影响最大。此外,固定面板回归的结果显示,根据企业的技术强度,产品相关服务与数字解决方案相结合的生产经理的财务绩效最高。

The mandatory implementation of the International Financial Reporting Standard 15 (IFRS 15) Revenue from Contracts with Customers starting with the 2018 financial year for all those companies using the IFRS has led to a significant change in approaching the accounting policies on profits, especially those related to their evaluation and identification within the financial statement. It is a fact that this significant change has had visible effects on the information disclosed by stakeholders especially given the stressful financial statement when both the costs themselves and the lack of cash flow have amplified these results. Consequently, the aim of the present study is both to evaluate the real impact of the use of the IFRS 15 in different fields of activity and to identify those solutions in terms of solving the issues for each and every significant sector given the stressful financial conditions, especially in those countries with an emergent economy. Thus, the main objectives of the study itself refer to the identification of the framework of applicability of the IFRS 15 and its matrix transposition in the form of a scoreboard based on certain cross-panel correlation keys and the design of an extended modelling methodology for applying the IFRS 15 based on dynamic indicators and indexes. The final results refer to the design of a replicable model of extended usage of the IFRS 15 which will serve all the analysed fields of activity. This up-to-date topic is the result of the implementation of the right model in itself as well as an accurate and objective evaluation of the value of those profits originating from the contracts signed with clients for all those categories of entities using the IFRS irrespective of the type of activity or the business model.
国际财务报告准则第15号(IFRS 15)从2018财政年度开始强制实施与客户合同收入,所有使用IFRS的公司都导致了利润会计政策的重大变化,特别是那些与财务报表中利润评估和识别相关的会计政策。事实上,这一重大变化对利益相关者披露的信息产生了明显的影响,特别是考虑到成本本身和缺乏现金流放大了这些结果的紧张财务报表。因此,本研究的目的是评估在不同活动领域中使用《国际财务报告准则第15号》的实际影响,并在财务状况紧张的情况下,特别是在新兴经济国家,就解决每个重要部门的问题而言,确定这些解决方案。因此,本研究本身的主要目标是确定《国际财务报告准则第15号》的适用性框架及其基于某些交叉面板相关键的记分牌形式的矩阵转换,以及设计基于动态指标和指数的应用《国际财务报告准则第15号》的扩展建模方法。最终结果指的是IFRS 15扩展使用的可复制模型的设计,该模型将服务于所有分析的活动领域。这一最新主题本身是实施正确模式的结果,也是对使用国际财务报告准则的所有类别的主体与客户签订的合同所产生的利润价值进行准确和客观评估的结果,无论其活动类型或商业模式如何。
