This article presents the results of a study examining the development of the European Union's energy supply structure and policy aimed at achieving the goals of ensuring high growth rates of renewable energy production and reducing energy dependence. It also provides a detailed analysis of the priorities and transformation of the management decision-making mechanism in the context of global climate change and a fundamentally new geopolitical situation.

An analysis of academic and practical experience of anti-crisis management in Russian regions has enabled to apply a new approach to modeling the dependence of regional development levels on allocated subsidies through the assessment of elasticity coefficients. Regions are divided into three groups based on the efficiency of subsidy use. The model has been tested using statistical data for 2021–2024. Further research directions are identified for adjusting the methodology for distributing subsidies to equalize the budgetary capacity of constituent entities of the Russian Federation and for developing new approaches to assessing the effectiveness of regional governance at the local level.

This article examines modern approaches to intangible incentives in the civil service and municipal administration. The author examines theoretical approaches to this issue based on recent research on employee incentives at both the federal and municipal levels. Based on a study of Russian practice and the existing academic literature, the author proposes incorporating a sectoral approach into public sector personnel policy for the professionalization and specialization of employees. This approach will take into account the territorial component and facilitate the intensification of the region's socio-economic development.

The key vectors of spatial transformation in various countries around the world are the formation of large macroregions, as well as the expansion and strengthening of agglomerations. This article aims to conduct a comparative analysis of the formation of metropolitan regions in Russia and China, given the changing spatial development vectors of these two countries. The comparative method formed the basis of the study and allowed us to draw parallels in the development trends of the Russian and Chinese metropolitan regions, while the systems approach allowed us to examine the spatial component of infrastructural transformations in the Moscow metropolitan region and the Beijing-Tianjin-Hebei region.

This article examines the institutional design of a public administration model in the context of geopolitical turbulence. The concept of a social sovereign economy underpins the substantiation of the principles and architecture of a governance system that ensures the sustainability and adaptability of national development. The article demonstrates that strategic policy priorities are shaped by social goals and national sovereignty. It highlights key characteristics of the long-term development vector: limited strategic openness of the economy, technological sovereignty as its foundation, an active role for the state, self-sufficiency and sustainability, integration of the economic and social dimensions, and a political and legal framework for public administration. A three-loop model is proposed: a multi-level governance architecture for a social sovereign economy, in which the external environment serves as an imperative of sovereignty and sets institutional constraints, while the internal loops are aimed at prioritizing domestic development and security. The paper presents mechanisms for institutional design: setting rules and incentives, and coordinating strategic planning tools for industrial, scientific, technological, and social policies. The authors argue that external environmental turbulence is a catalyst for the transition from a model of integration into the global economy to a model of social sovereignty to ensure national resilience, security, and autonomy.

The article explores China's experience in using the concept of best available technologies (BAT) in national environmental and economic policy. The Chinese approach, on the one hand, draws heavily on approaches adopted in the European Union, while also taking into account the specifics of national socio-economic development conditions. Furthermore, the article assesses the potential and advantages of using BAT as a priority mechanism for environmental and industrial policy in developed countries, and analyzes the conditions that, if met, largely ensure the successful practical implementation of this concept. The BAT approach, as interpreted by China, includes legislative and regulatory measures, as well as significant government support and proactive activities of companies themselves. These measures are largely consistent with the development of a new model of economic growth associated with the creation of a green economy and ensuring sustainable development.

The article presents the application of a developed methodology for assessing the performance of innovation infrastructure organizations in a specific region. The need for such an assessment is linked to the implementation of innovation policy in the Russian Far East, specifically the activities of the organizations involved. To achieve the objective of the study, a theoretical section is presented, reflecting the current state of the region's innovation infrastructure and demonstrating the specific level of its scientific and technological development, including that of individual cities. The practical part of the work focuses on the step-by-step application of the assessment methodology to one of the analyzed innovation infrastructure organizations. Using this methodology, the performance of other organizations was similarly determined, allowing for an assessment of the region's overall level of development.

The paper presents a hybrid zero-knowledge proof protocol, QZKP-Hybrid, designed to protect information from quantum and classical attacks. The protocol combines two approaches: quantum-resistant lattice cryptography (LWE) and quantum methods using special quantum states ∣ϕ_x⟩ and SWAP testing. The protocol solves the classical zero-knowledge proof problem (ZKP) in a post-quantum context and finds application in authentication, digital signatures, and blockchain. The protocol is non-interactive due to the Fiat-Shamir transformation. A prohibition on cloning quantum states is also used, physically protecting secret information from forgery. The security of QZKP-Hybrid is proven in the UC security model using a sequence of hybrid games. It is proven that no adversary, even with a quantum computer, can break the protocol. The protocol can be implemented using existing technologies. For example, fiber-optic channels can be used to transmit quantum states, allowing the protocol to be implemented in real-world systems. QZKP-Hybrid can be used in post-quantum systems. It is suitable for tasks where data must be hidden while still being verified. The protocol has demonstrated a good balance between security and performance. With a parameter size of n = 512, it operates quickly and requires little memory. This allows it to be used in mobile devices and IoT systems. Future research plans include studying the impact of decoherence and noise on protocol accuracy and extending the model to multiple participants.
