There is a need to explore and comprehend the performance of sustainable leadership in enterprises’ circular economy-driven innovative activities. Firstly, there is a pressing necessity for businesses to remain agile and responsive to change, utilizing innovation not just as a buzzword but as a strategic tool for adaptation and growth. Secondly, the ethical dimension demands that innovation be pursued responsibly, considering its effects on communities, environments, and future generations. Lastly, the economic imperative underscores that sustainable innovation management can lead to efficiencies, cost savings, and new avenues for revenue generation. An improved comprehensive approach to evaluating the effectiveness of managing enterprises’ innovative activities is proposed. This approach is based on the evaluation of 14 partial indicators, each reflecting a specific vector orientation. This assessment allows for the combination of indicators that essentially reflect the personal characteristics of the manager and the combination of formative and resultant factors of the management’s influence on the state and results of innovative activity (the above-proposed factor approach). Consequently, it provides an opportunity to obtain a multifaceted, comprehensive, and most complete assessment of the sustainable management of innovative activity based on valid vector orientation within the scope of the subject and the object of research. Based on the proposed improved assessment, indicators of the effectiveness of managing innovative activities were calculated for the seven researched innovatively active industrial enterprises. Thus, the following were calculated: (1) the personal component (Pp) of the evaluation of the effectiveness of leadership in innovative activities using the expert assessment toolkit, (2) the managerial component (Plm), and (3) the innovatively sustainable component (Pis) of the evaluation of the effectiveness of sustainable management of innovative activities based on the internal reporting of the enterprise. This balances the partial subjectivity of the expert method with real data from specific enterprises. Consequently, based on the values of the three assessment components, a comprehensive integral indicator of the effectiveness of managing the innovative activity of the enterprise (Pef) was calculated. The proposed methodology’s validation proved its effectiveness and efficiency. The authors forecast the degree of influence of external and internal factors, taking into account the results of a comprehensive, integrated assessment of the effectiveness of sustainable management (Pef) on the economic development and indicators of the enterprise’s circular economy-driven innovative activities. This enables a significant strengthening of the resultant factors of managing innovative activities and predicting specific final results of all innovative activities.

Забезпечення безпеки підприємництва набуло особливої актуальності в контексті геополітичних конфліктів, зростаючої диджиталізації та впровадження нових технологій у фінансовий і виробничий сектор, збільшення частоти й складності кібератак, спрямованих на сферу бізнесу, а також активізації застосування штучного інтелекту. Стаття присвячена розкриттю специфіки забезпечення безпеки підприємництва в Україні у воєнний час із використанням штучного інтелекту та кіберзахисту. Проведено ретроспективний огляд літератури, показано відсутність досліджень щодо використання штучного інтелекту в забезпеченні безпеки підприємницької діяльності, що свідчить про наукову новизну цієї статті. Висвітлено проблеми та загрози, які постали перед державними й приватними бізнес-структурами при здійсненні підприємницької діяльності; війна з росією потребує врахування нових реалій ‒ диджиталізації економіки, боротьби з кіберзагрозами, використання нових інноваційних технологій і штучного інтелекту. Констатовано діапазон тригерів, що генерують серйозні збої в бізнесі, які пов’язані з кібернетичною діяльністю, включаючи застосування штучного інтелекту, зловмисні атаки злочинців чи хакерів, витік інформації, людський фактор або відмову техніки. Акцентовано увагу на тому, що невідлагодженість нормативно-законодавчої бази у сфері кібербезпеки також робить бізнес вразливим перед можливістю руйнації. Окреслено можливості застосування та загрози штучного інтелекту для безпеки підприємництва. Сформульовано напрями вбезпечення підприємництва в умовах війни за допомогою штучного інтелекту та усунення / мінімізації кіберзагроз. Висвітлено стан нормативно-законодавчої бази, що регламентує регулювання кібербезпеки в Україні, та запропоновано напрями її поліпшення.

Type of the article: Research ArticleAbstractRecent assessments by the IEA, IRENA, and the World Bank indicate that data- and algorithm-driven operations can enhance energy security by increasing efficiency, reducing curtailment, and stabilizing grids as the renewable share grows, while also warning of ecological trade-offs from rising digital electricity use. Against this backdrop, government AI readiness emerges as a crucial enabling condition, providing the institutional and technological capacity to translate climate and sustainability targets into day-to-day energy system performance. Framed through an environmental lens, the study examines whether government AI readiness acts as an ecological enabler that strengthens energy security by supporting the integration of renewable energy, reducing emissions, and enhancing system resilience. To test this ecological proposition, we assemble a balanced panel of 125 countries (2020–2023), combining the Oxford Insights Government AI Readiness Index with the World Energy Council’s Energy Security Score as an operational proxy for environmentally robust energy systems. Using panel methods (fixed and random effects), with diagnostics for serial correlation, cross-sectional dependence, and heteroskedasticity, and Driscoll-Kraay standard errors for robust inference, we find that in the random-effects specification, a one-point rise in AI readiness is associated with a 0.1104-point improvement in the energy security score (p < 0.001). The effect remains statistically significant after accounting for temporal and cross-sectional dependencies, supporting the view that institutional preparedness to use AI can act as an enabling ecological instrument, facilitating the integration of renewable energy, demand-side efficiency, and system resilience, which together underpin cleaner, more secure energy.AcknowledgmentThis study was prepared as part of the project 101127491-EnergyS4UA-ERASMUS-JMO2023-HEI-TCH-RSCH.

Efficiently functioning entrepreneurship has been considered at all times as an important condition for the development of a market economy. Business enhances a country's security and competitiveness on the world stage in a globalised world. The phenomenon of entrepreneurship is a multidimensional and complex phenomenon. Business development is conditioned by many factors that stimulate or inhibit its functioning. Under such conditions, an urgent issue of modern science is to develop a methodology to identify structural changes in entrepreneurship, as well as to forecast possible variants of its development taking into account current changes in the market environment. The information base for our study was the reporting data on entrepreneurship development for 2010-2020, officially promulgated on the website of the State Statistics Service of Ukraine. In writing the article, we used a system of methods that allow us to determine the structural changes in entrepreneurship in the context of globalisation best, as an example: scientific abstraction, analysis, hypothetical and logical methods, methods of absolute and comparative advantages. The index method was used to analyse the impact of the number of employees and labour productivity on the volume of sold products. To study the dynamics of structural changes in entrepreneurship in Ukraine and to forecast the corresponding indicators for 2023-2024 an adaptive forecast model of Holt was used. The implementation of the proposed methods and modelling tools allowed us to analyse the dynamics of changes in entrepreneurship in Ukraine and to forecast its further development. It was determined that a significant feature of the dynamics of the distribution of employees by types of enterprises is a clearly expressed trend of reducing the share of employees of large enterprises with an increase in the share of employees of medium enterprises and individual entrepreneurs with no significant changes in the share of employees of small businesses. The peculiarity of the dynamics of the distribution of products sold by types of enterprises is a clear tendency of a decrease in the share of products of large enterprises with the growth of the share of medium enterprises, small enterprises and individual entrepreneurs. At the same time, the shares of production of large and medium enterprises significantly exceed the shares of small enterprises and individual entrepreneurs. This ratio, in accordance with the received forecasts, also took place in the forecast period for 2023-2024. The analysis of structural changes in entrepreneurship allows some conclusions and suggestions to be made. Thus, in order to support the development of entrepreneurship, there is a need to form a critical mass of managers able to respond to changes in the external environment in a timely manner and to make effective decisions. In the formation of public policy to stimulate business development, the relevant issue is the provision of preferential loans to business entities to upgrade fixed assets, which will significantly improve production and save entrepreneurial resources. In addition, an important issue is the attraction of human resources into entrepreneurship, especially those working on an innovative basis.
