The article is devoted to highlighting the state of Ukrainian entrepreneurship in the conditions of war through the prism of defining economic challenges, threats and opportunities. Method. To achieve the goal of the research, general scientific and special methods of cognition were used. In the work, methods of analysis and synthesis were applied in assessing the state of entrepreneurship in Ukraine; grouping, comparison and generalization when analyzing existing initiatives to support entrepreneurship in wartime; methods of graphical and tabular display of research results. Results. The state of entrepreneurship in Ukraine is defined and the main directions of business entities' activities in the pre-war period are indicated. The consequences of the impact of the war are characterized, in particular, regarding changes in the quantitative composition of active business entities and the results of their work in the conditions of a full-scale war. The main threats and problems of the modern development of entrepreneurship are highlighted. Scientific novelty. Using a systematic approach in evaluating existing initiatives to support Ukrainian entrepreneurship in the conditions of martial law, it is proposed to use a comprehensive approach in finding optimal ways to minimize and overcome existing problems and to determine priority measures for the restoration of business activity of business entities, their adaptation to atypical conditions and effective development in the post-war period. Practical significance. It is noted that a number of separate initiatives at the level of regional state administrations and city councils, which complement state programs, have been developed and implemented to support the development of Ukrainian entrepreneurship in wartime conditions. It was determined that donor support and initiatives of private companies and foundations are no less important in terms of scope and value. In general, entrepreneurship support should be implemented comprehensively, because a quick positive effect can be achieved only by implementing various measures and combining the efforts of individual support groups (state, local, donor and private). In general, it is determined that new programs aimed at supporting the revival of business activity of business entities should stimulate them to implement more innovative and sustainable practices that cover the principles of circular and green economy, reducing the energy intensity of production and promoting cooperation.","PeriodicalId":498426,"journal":{"name":"Review of transport economics and management","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135167755","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}

To achieve the goal, a wide range of general scientific and special methods of analysis and synthesis, economic and logical methods of comparison, grouping, graphic method and others were used. The results. The structure of small and medium-sized business entities by region of Ukraine was studied. The predominance of the number of small enterprises compared to the average in all regions was determined, which is explained by the ease of registering business activities, a simplified taxation system, and less dependence of small enterprises on attracting long-term and significant amounts of financial resources. It is shown that the number of small enterprises in all regions of Ukraine varies between 93-96.5%, and the number of medium-sized enterprises is between 3 and 7%. An analysis of the activity of small and medium-sized business entities in the Ivano-Frankivsk region was conducted, which showed that there was a decrease in the number of employed workers at small and medium-sized business enterprises. Labor costs and volumes of products sold by enterprises of the Ivano-Frankivsk region, which had a steady trend of growth among small and medium-sized enterprises, were also analyzed. On the basis of the conducted analysis, the directions of the economic recovery of the Ivano-Frankivsk region with regard to the activation of small and medium-sized businesses, which will contribute to the improvement of the business climate, the attraction of investment resources and the establishment of competitive economic activity in the region, are substantiated. Scientific novelty. A scientific-methodological approach to assessing the state of small and medium-sized business entities is proposed. The practical significance.

The article is devoted to the study of the modification essence of competitive strategies as a result of the impact of crisis phenomena on the example of the activities of airlines. Methodology. Research methods include methods of scientific abstraction, observation, synthesis, generalization to highlight the key features of airlines competitive strategies, system-structural analysis of the market. The classification system of Porter's general strategies was applied in the airline sector. Results. Functional-level strategies in different areas of the firm, such as marketing, operations, finance, can only be properly developed when there is clear understanding of the overall business strategy. The article discusses general strategies that are available to all firms regardless of the sector, in accordance with Porter's view of activities differentiation and low cost, taking into account the breadth of operational goals. The focus was on airline operations, indicating the competitive strategies of full-service network carriers, low-cost carriers, integrated cargo carriers, regional airlines, charter airlines, and carrier-within-a-carrier airlines. These business models form the spectrum of strategic choices that will mix and function in hybrid forms as airlines continue to add nuance to their diverse approaches. The impact of crisis phenomena is direct factor in the hybridization of competitive strategies, although budget airlines have proven to be the most stable business models in terms of staff reduction. Scientific novelty. The competitive strategies of enterprises for the aviation sector and the business models of airlines, which respond to the global crisis challenges to varying degrees, are adapted, among which the budget business model is the most stable due to low operating costs. It was established that the business models of airlines are characterized by the approach of hybridization and mixing of business model features. Practical significance. The obtained results contribute the further development of theoretical approaches to the marketing research of airline activities, the analysis of the functioning of the air transport market. The materials reflect the generalization of competitive strategies of airlines.","PeriodicalId":498426,"journal":{"name":"Review of transport economics and management","volume":"192 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135167968","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 purpose of the article was to find protection against the negative consequences of the professional crisis of education, which would be based on moral values and contribute to the integration of constructive ideas of past generations into the present. Methods. It is proposed to implement the idea of psychoprophylaxis using historical methods. The results. The factors of the crisis in the professional training of applicants for economic and military specialties are characterized. The peculiarities of the structure of mental phenomena and the concept of psychological support of the process of psychoprophylaxis are considered. The need to implement a systematic approach based on empirical data, including research aimed at harmonizing the psychological state, is emphasized. Scientific novelty. Empirical research has revealed the peculiarities of the social functioning of applicants of economic and military specialties. The practical significance. There are differences in the psychological well-being of specialists in economic and military specialties: they are characterized by a predominance of interest in history, which reflects interest in the profession, admiration for it; during a crisis, self-esteem and locus of control reach levels that indicate inadequate assessment and inability to use one's own strengths to achieve a goal. Psychological support of professional adaptation in this period involves determining the volume, quality and form of providing information about the enterprise, economy, division, specifics of activity, various services, about the team, its structure, traditions, group norms, social expectations. As a rule, such information comes to the adapting person in one form or another, in sufficient or excessive amounts, but without scientific justification. The conducted investigations allow us to draw preliminary conclusions. Indeed, the professional formation of students is accompanied by critical moments, the most difficult of which is the crisis of professional training, which falls on the 3rd year. Providing psycho-prophylactic help by applying the proposed historical-scientific method makes it possible to prevent extremely negative consequences that can deform the personality. Accordingly, further development and approval of the historical-scientific method of psychoprophylaxis against a wider background is necessary in order to recommend its use to teachers and students.","PeriodicalId":498426,"journal":{"name":"Review of transport economics and management","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135167764","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 concept of integrated reporting significantly expands the effectiveness of corporate reporting of companies. Integrated reporting is able to satisfy the information needs of a wide range of users, as it involves combining in one document financial information on value creation, risk management, with information on social responsibility and environmental consequences of activity. The experience of European countries in the preparation of integrated reporting touches on the issues of improving transparency, efficiency, environmental and social responsibility of private companies and state institutions, disclosure of information about the contribution to achieving the goals of sustainable development. The purpose of the article is to compare the experience and national features of the preparation of integrated reporting of European countries, review the regulatory and legal regulation and the practice of information disclosure. Method. During the research, such scientific methods as analysis, synthesis, comparison, systematization, induction, deductive method, analogy, modeling, system approach were used. Results. Integrated reporting is the result of integrated thinking reflected in the reporting of the company's value creation. In Europe, the practice of preparing integrated reporting is most common in France, Denmark, Belgium, Germany, Italy, Spain, Sweden, the Netherlands and Great Britain. The main differences between countries are the lack of uniform rules and standards, the significant influence of national legislation, the variability of reporting entities, the content and format of integrated reporting, its audit, mental understanding and perception. Integrated reporting of European companies is based on the requirements of Directives 2014/95/EU and 2013/34/EU, the IIRF International Conceptual Framework, GRI, ESG, IFRS, SDG standards.
