The relevance of the article explained by the fact that knowledge economy calls for knowledge management, and modern knowledge management is a new type of management that emerged in the days of the knowledge economy. The purpose of this paper is to investigate spatiotemporal characteristics of public attention towards knowledge management in China. The leading research methods were analysis, synthesis, comparison, deduction, and induction. This study uses Baidu index to analyse the spatiotemporal characteristics of the public's attention to knowledge management. It was noted that the trend of finding “knowledge management” for the last 11 years peaked at the end of 2016, and the decrease appeared around National Day each year. It was stated that the groups concerned about “knowledge management” are mainly distributed in Guangdong, Beijing, and Shanghai. The factors that affect the changes in the search volume of “knowledge management” include the traditional Chinese holidays, the Spring Festival, the National Day, and the release of knowledge management-related norms. In addition, the study found similar search trends for “knowledge management” and “knowledge management system”. It was concluded that the knowledge management systems are used only when the amount and complexity of knowledge accumulation within an organisation reaches a certain level
文章的相关性在于知识经济呼唤知识管理,而现代知识管理是知识经济时代出现的一种新型管理方式。本研究旨在探讨中国公众对知识管理关注的时空特征。主要的研究方法是分析、综合、比较、演绎和归纳。本研究采用百度指数分析公众对知识管理关注的时空特征。报告指出,过去11年来,“知识管理”的发现趋势在2016年底达到顶峰,每年国庆节前后出现下降。报告指出,关注“知识管理”的群体主要分布在广东、北京和上海。影响“知识管理”搜索量变化的因素包括中国传统节日、春节、国庆节以及知识管理相关规范的发布。此外,研究发现“知识管理”和“知识管理系统”的搜索趋势相似。结论是,只有当组织内知识积累的数量和复杂性达到一定水平时,才能使用知识管理系统

The digitalisation of public administration is a process aimed at improving access to goods and services. The demand for facilitating access to services, in particular public services, and boosting the economy, to which the digital transformation can contribute, makes this study relevant. The purpose of this study is to analyse current trends in the digital transformation of public administration and public authorities. The study employed general scientific methods, in particular analysis and synthesis, and comparative methods. Areas for improving the efficiency of decision-making by public authorities through the use of information and communication technologies and digitalisation were considered. It has been substantiated that the intensified use of the latest information technologies in providing various services by public authorities determines the beginning of the formation of its own model of digitalisation of public administration. The digital transformation of public administration is defined as a problem-solving tool for the society that can provide significant savings in public expenditure, benefiting the administration and the citizens, whose daily needs and concerns are placed at the centre of public administration strategies. The impact of digitising services for citizens has been shown to be effective, in particular in facilitating access to and use of services. The necessary conditions for successful digital transformation were identified
公共行政的数字化是一个旨在改善商品和服务获取的过程。数字化转型有助于促进服务(特别是公共服务)获取和促进经济发展,因此本研究具有现实意义。本研究的目的是分析公共行政和公共权力机构数字化转型的当前趋势。这项研究采用了一般的科学方法,特别是分析、综合和比较方法。讨论了通过使用信息通信技术和数字化提高公共当局决策效率的领域。事实证明,公共当局在提供各种服务时越来越多地使用最新的信息技术,决定了它自己的公共行政数字化模式的形成。公共行政的数字化转型被定义为社会解决问题的工具,可以节省大量公共支出,使行政部门和公民受益,他们的日常需求和关注被置于公共行政战略的中心。数字化服务对公民的影响已被证明是有效的,特别是在便利服务的获取和使用方面。确定了数字化转型成功的必要条件

The relevance of the study comes from Ukraine being the largest agricultural country on the European continent by its size, with 41.5 million ha, and the second-largest arable land on the continent, mainly comprising humus-rich chernozems. Agriculture and agribusiness remain one of the driving forces of Ukraine’s economy, generating 15% of its GDP, employing 20% of the working population and accounting for 40% of the country’s exports. To support and bolster the agricultural sector, the state is developing and implementing reforms, the most significant of which is the introduction of a land market. In this context, Ukrainian agriculture has favourable conditions for development, but the exact effect of the implemented reforms remains unclear. The purpose of the study is to assess the state and trends in the development of agriculture in Ukraine in the context of ongoing reforms. The study employed the following methods: abstract-logical (through this method the main aspects of land reform and economic reform development strategy were identified), system analysis (the state of the Ukrainian economy was assessed), retrospective (the development of the agro-sector since Ukraine gained its independence was considered) and predictive (possible development scenarios were suggested). It was determined that it will take some time to manifest all the positive aspects of the reform, and its implementation involves a number of risks for small-scale farming. It became clear that climate changes also have an impact on agricultural productivity, and under its influence, some lands in Ukraine (e.g., the south) have already started to lose their value due to global environmental issues. The practical significance lies in determining the status and trends of agricultural development in the context of the structural reform of the national economy of Ukraine
这项研究的相关性在于乌克兰是欧洲大陆上最大的农业国,面积为4150万公顷,是欧洲大陆上第二大耕地,主要由富含腐殖质的黑钙土组成。农业和农业综合企业仍然是乌克兰经济的驱动力之一,占国内生产总值的15%,雇佣了20%的劳动人口,占该国出口的40%。为了支持和加强农业部门,国家正在制定和实施改革,其中最重要的是引入土地市场。在这种情况下,乌克兰农业具有有利的发展条件,但实施的改革的确切效果仍不清楚。该研究的目的是评估在正在进行的改革背景下乌克兰农业发展的状况和趋势。本研究采用以下方法:抽象逻辑(通过该方法确定土地改革和经济改革发展战略的主要方面),系统分析(评估乌克兰经济状况),回顾性(考虑乌克兰获得独立以来农业部门的发展)和预测(提出可能的发展方案)。会议确定,需要一段时间才能体现改革的所有积极方面,而改革的实施涉及小规模农业的一些风险。很明显,气候变化也对农业生产力产生影响,在其影响下,乌克兰的一些土地(例如南部)已经开始因全球环境问题而失去价值。其现实意义在于确定乌克兰国民经济结构改革背景下农业发展的现状和趋势

The confectionery industry is of significant importance for the stable development of the country for many economic reasons, it’s an ancient and effective industry, creating serious competition in the international market of confectionery products. Therefore the purpose of the scientific article is the analysis of the market of confectionery products in Ukraine and estimation of features of promo campaigns of the Ukrainian manufacturers of confectionery products. In the course of writing the article, both theoretical and statistical methods of data analysis were used. The found information about differences in marketing campaigns of Ukrainian manufacturers of confectionery products is supported by graphs, tables, and diagrams for clarity and ease of perception. It is pointed out that Ukrainian confectionery companies are competitive both on foreign and domestic markets. It has been found that the success of Ukrainian confectionery companies is based on many factors that influence their results to a different extent: management, product quality, logistics, start-up capital, the economic and political situation in the country, luck, and others. It is determined that the marketing campaign of the enterprise is used mainly to attract customers. The article also describes the promo campaigns of major national confectionery companies, their features, and differences, since even a few major players in this market have significant differences in marketing campaigns. The article, for practical purposes, can be used to study marketing methods often applied by large product manufacturers; to research the Ukrainian economy as a whole; to evaluate Ukrainian companies that are major suppliers to the Ukrainian confectionery market; by students to study marketing and advertising issues and various economic disciplines related to entrepreneurship

With the implementation of the European Green Deal, the circular bioeconomy model is gaining in relevance as well as the concept of circular bioeconomy, which promotes a renewed economic approach to conducting economic activity. The transition of a socio-economic system from one qualitative state to another, causes the need to measure dynamic changes and establish progressive factors towards the formation of a circular business environment. The objective of the study is to monitor the measurement system of the circular bioeconomy and to outline criterial limitations and relevant indicators based on the defined characteristics. The methodological basis of the study consists of the methods of empirical and theoretical level, particularly the historical, abstract-logical, descriptive, comparative methods, method of observation and formalisation, theoretical generalisation, etc. In the process of scientific research, it was possible to carry out comprehensive monitoring of scientific developments of foreign and Ukrainian scientists and to establish existing methodological approaches to assessing the circular bioeconomy. A review of the literature provided an opportunity to identify key structural components that are within the sectoral space and targets that have a complementary relationship with the three-dimensional sustainable development. Sectoral segmentation and target gradation by circular orientation and bioeconomic manifestation allowed to form a system of indicators for measuring the circular bioeconomy according to the established criteria. The practical value of the study consists in the scientific substantiation of the criterial characteristics of the measurement of the circular bioeconomy and the establishment of a system of indicators with relevant limitations
随着《欧洲绿色协议》的实施,循环生物经济模式和循环生物经济概念的相关性越来越大,循环生物经济促进了一种新的经济方法来开展经济活动。社会经济制度从一种质的状态过渡到另一种质的状态,导致需要衡量动态变化,并为形成循环商业环境建立进步因素。本研究的目的是监测循环生物经济的测量系统,并根据已定义的特征概述标准限制和相关指标。研究的方法论基础包括实证和理论两个层次的方法,特别是历史方法、抽象逻辑方法、描述方法、比较方法、观察和形式化方法、理论概括方法等。在科学研究过程中,有可能对外国和乌克兰科学家的科学发展进行全面监测,并确定评估循环生物经济的现有方法。对文献的审查提供了一个机会,以确定部门空间内的关键结构组成部分和与三维可持续发展具有互补关系的目标。根据循环导向和生物经济表现进行行业划分和目标分级,形成了按既定标准衡量循环生物经济的指标体系。本研究的实用价值在于科学地确立了循环生物经济计量的标准特征,并建立了具有相应局限性的指标体系

The organisation of resource support for the needs of the Armed Forces of Ukraine is an important daily task related to the distribution of material resources for their intended purpose. If there is a sufficient resource base and the factors of time, speed, and priority of delivery of funds are secondary, resource support is carried out according to the principles “if necessary” and “if possible”. However, the practices of resource support for the needs of the Armed Forces of Ukraine considering the limited resource capabilities of the national economy and other similar tasks, as a rule, demonstrates the necessity of acting in the conditions of quantitative and qualitative restrictions of the resource base. Moreover, in the conditions of requirements for reducing the time of implementation of resource support, considering the priority of resource assignment objects and different levels of their initial resource provision. The purpose of this study is to find the best, rational, and even optimal distribution of resources for certain characteristics in three types of business conditions: certainty, uncertainty, and risk in managerial decision-making. Based on the analysis of available methods of nonlinear programming in distribution problems, proceeding from the condition of maintaining mathematical correctness and accessibility to practical use, the study presents the procedure for applying the maximum element method. The proposed approach to optimising the distribution problem is considered on the example of possible distribution options for equally efficient resource supply between the resource supply facilities. The options differ in the values of the importance of objects and the levels of initial supply in relative units at the time of decision-making on the allocation of resources upon providing resources for a certain final management task. The methodology of this study can be used in planning and decision-making related to the distribution of resources in organisational systems of military and civil administration, considering the importance and initial state of adequate supply of destination facilities in case of limited capabilities of the resource manager
为乌克兰武装部队的需要组织资源支助是一项重要的日常任务,与为其预定目的分配物质资源有关。如果有足够的资源基础,资金交付的时间、速度和优先次序等因素是次要的,则按照“必要时”和“可能时”的原则进行资源支持。但是,考虑到国民经济和其他类似任务的资源能力有限,为乌克兰武装部队的需要提供资源支助的做法通常表明,必须在资源基础受到数量和质量限制的情况下采取行动。此外,在要求缩短资源支持实施时间的情况下,考虑资源分配对象的优先级及其初始资源提供的不同级别。本研究的目的是在管理决策的确定性、不确定性和风险三种类型的商业条件下,找到某些特征的最佳、合理甚至最优的资源分配。在分析现有分布问题非线性规划方法的基础上,从保持数学正确性和实用性的前提出发,给出了最大元法的应用步骤。以资源供应设施之间资源供应效率相等的可能分配方案为例,考虑了优化分配问题的建议方法。在为某一最终管理任务提供资源时,在对资源分配作出决策时,这些选择的不同之处在于对象的重要性值和相对单位的初始供应水平。本研究的方法可用于与军事和民政管理组织系统的资源分配有关的规划和决策,考虑到在资源管理人员能力有限的情况下目的地设施供应充足的重要性和初始状态

The relevance of the research is due to the rapid development of the securities market. Financial instruments have been improving in Ukraine for a long time, new intermediaries and market participants have been appearing. Consequently, there is a growing need for effective regulation of changes that are mainly intra-economic and can affect various spheres of public life. The work aims to identify modern features of the functioning of the Securities Market on the territory of Ukraine. Taking into account the interdisciplinarity of this topic, analysis, synthesis and induction were chosen as the leading research methods. These systems of procedures were combined primarily to form ideas about the relationship between economics and law. In this context, the first method contributed to the objectification of the properties of securities; thanks to the synthesis, it was possible to draw complete conclusions and generalisations about the directions of development of the relevant market. At the same time, the induction was used to obtain a general conclusion about the possibilities of regulating the securities market. The article provides an essential description of the concepts of “securities market” and “stock market”. In addition, the structure of the financial market was determined: the main organisers of trade and its participants. The main laws were also presented in the field of legal regulation of the securities market of Ukraine and the EU. Finally, the development was justified of the Ukrainian stock market in the context of European integration processes. The article materials are of theoretical and practical importance for bank employees, financial management specialists, credit brokers, auditors and insurance agents. Due to the availability of a description of the international practice of using financial instruments, the study may be of interest to representatives of public authorities and educational organisations. However, the approximation of the legislation of Ukraine in the field of securities circulation to European standards will remain a controversial issue for each of these groups of people
这项研究的意义在于证券市场的快速发展。长期以来,乌克兰的金融工具不断改进,新的中介机构和市场参与者不断出现。因此,越来越需要对主要是经济内部的变化进行有效监管,这些变化可能会影响到公共生活的各个领域。这项工作旨在确定乌克兰境内证券市场运作的现代特征。考虑到该主题的跨学科性,选择了分析、综合和归纳作为主要研究方法。将这些程序系统结合起来,主要是为了形成有关经济与法律之间关系的观点。在这种情况下,第一种方法有助于将证券的属性客观化;由于采用了综合法,有可能对相关市场的发展方向得出完整的结论和概括。与此同时,归纳法还被用于获得关于规范证券市场可能性的一般性结论。文章对 "证券市场 "和 "股票市场 "的概念进行了基本描述。此外,还确定了金融市场的结构:交易的主要组织者及其参与者。文章还介绍了乌克兰和欧盟证券市场法律监管领域的主要法律。最后,对乌克兰证券市场在欧洲一体化进程中的发展进行了论证。文章资料对银行职员、金融管理专家、信贷经纪人、审计师和保险代理人具有重要的理论和实践意义。由于提供了使用金融工具的国际惯例说明,公共机构和教育组织的代表可能会对本研究感兴趣。然而,乌克兰在证券流通领域的立法与欧洲标准的接轨仍将是上述各类人群的一个有争议的问题。

The modern economic space is characterised by the actualisation of such market structure as an oligopoly, which necessitates its proper theoretical and empirical investigation. The aim of the paper is to analyse the use of game theory in the oligopoly market under the said conditions. The theoretical methods are the main scientific methods used in this study, in particular analysis, synthesis, historical and statistical methods. It was determined that the game theory is one of the most important relatively new mathematical theories applied in developing various types of economic models, including market analysis and companies activity strategy formation. It has been confirmed that the game theory is most often applied to oligopoly market analysis i.e. the market in which two or more big players conduct activities. Their decisions influence both the market in general and other “players”' income and position in the market by influencing the output price or the volume of output (depending on the model). It is stated that there are many ways to apply game theory as the main theory and to explain the future state of the market, incomes, losses, and producers' share in the oligopoly market due to different conditions and variables. This paper has reviewed the use of game theory subject to antitrust restrictions and when oligopolistic companies mutually benefit. It was substantiated that quite often in the models generated by economists, the mutual benefit of companies in an oligopoly market implies the existence of collusion between market participants in which companies benefit more than they would under the condition of competition between them (cartel). The practical value of the paper is in the theoretical substantiation of game theories in markets in general and in providing some practical strategies for companies' operations in markets, which will also be useful for students in their studies and for other scholars of economic disciplines
现代经济空间的特点是寡头垄断市场结构的实现,这需要对其进行适当的理论和实证研究。本文的目的是分析在上述条件下博弈论在寡头垄断市场中的应用。理论方法是本研究采用的主要科学方法,特别是分析、综合、历史和统计方法。确定博弈论是最重要的相对较新的数学理论之一,应用于开发各种类型的经济模型,包括市场分析和公司活动战略形成。已经证实,博弈论最常应用于寡头垄断市场分析,即两个或两个以上大玩家进行活动的市场。他们的决定通过影响产出价格或产出数量(取决于模型)来影响总体市场和其他“参与者”的收入和在市场中的地位。本文指出,在不同的条件和变量下,以博弈论为主要理论来解释寡头垄断市场的未来状态、收入、损失和生产者的份额有很多种方法。本文回顾了博弈论在受反垄断限制和寡头垄断公司互利的情况下的应用。事实证明,在经济学家建立的模型中,寡头垄断市场中公司的互利往往意味着市场参与者之间存在勾结,在这种勾结中,公司比在它们之间竞争的情况下(卡特尔)受益更多。本文的实用价值在于对一般市场中的博弈论进行了理论论证,并为企业在市场中的运作提供了一些实用的策略,这对学生的学习和其他经济学科的学者也有帮助

The relevance of the research is determined by the need to update the management structure of scientific projects within higher educational institutions in accordance with modern economic realities and internationally recognized standards, the essence of which is the transition from a rigid hierarchical management system and orientation towards the commercialization of the results of scientific and technological activities. Therefore, the purpose of this scientific article is to develop a functional model for scientific project management within higher education, the components of which, unlike existing models, will be characterized by a project-oriented direction. To achieve a certain research goal, general scientific research methods were used, including analysis, synthesis, generalization, comparison, systematization, modeling, as well as structural and mathematical methods, taking into account the key principles of structural-functional and system approaches. The article analyzes a number of scientific works of Ukrainian and foreign scientists on the topic of methodological substantiation of the specifics of management of research projects in higher educational institutions. The key concerns of the current state of scientific project management within the Ukrainian scientific space have been identified, in particular, the rigid organizational and staff management structure with the predominant role of the top management, insufficient financial support of scientific and technical activities, as well as limited access to the results of scientific and technical activities. The author’s economic and mathematical model of scientific project management in higher education institutions has been developed considering functional indicators. It is proposed to introduce a body for commercialization of the results of scientific and technical activities, which will help optimize the financial support of scientific and technical activities. The necessity of developing international cooperation within the framework of scientific and technical activities and the organization of scientific projects in particular is substantiated. The practical value of scientific work lies in the development of the author’s own methodological support for the proper functioning of scientific project management with the prospect of its further application in practice
研究的相关性取决于需要根据现代经济现实和国际公认的标准更新高等教育机构内科学项目的管理结构,其实质是从严格的等级管理制度过渡到科学和技术活动成果的商业化。因此,这篇科学文章的目的是为高等教育中的科学项目管理开发一个功能模型,与现有模型不同,该模型的组成部分将以面向项目的方向为特征。为了达到一定的研究目标,在考虑结构-功能和系统方法的关键原则的基础上,采用了一般的科学研究方法,包括分析、综合、概括、比较、系统化、建模以及结构和数学方法。本文分析了乌克兰和外国科学家关于高等院校科研项目管理细节的方法论实证问题的一些科学著作。已经确定了乌克兰科学领域内科学项目管理现状的主要问题,特别是组织和工作人员管理结构僵化,最高管理人员占主导地位,科学和技术活动的财政支助不足,以及获得科学和技术活动成果的机会有限。考虑功能指标,建立了高校科学项目管理的经济数学模型。建议设立一个科技活动成果商业化机构,这将有助于优化科技活动的财政支持。在科学和技术活动的框架内发展国际合作,特别是在科学项目的组织范围内发展国际合作的必要性得到了证实。科学工作的实践价值在于作者为科学项目管理的正常运作提供了自己的方法支持,并展望了科学项目管理在实践中的进一步应用
