The article considers economic and mathematical models in the context of monetary stimulation of financial and economic development of the smart industry. The article analyses AD-AS, DSGE, VAR, CAP, RBC, Phillips Curve and Cobb-Douglas models. The advantages and disadvantages of the models in the context of monetary stimulation of smart industry development are identified. The analysis has revealed that all the considered models have certain disadvantages, such as complexity of use and lack of clarity in interpreting the results, as well as limited consideration of factors that are important in monetary stimulation of the smart industry. The reviewed VAR model is limited in taking into account all factors affecting economic variables and is sensitive to specification, which leads to significant changes in the final results depending on the included variables and their specification. The CAP model is based on assumptions about market efficiency that do not always correspond to reality, while the RBC model is characterised by the absence of instability and unrealistic assumptions about market behaviour. The Phillips Curve model shows instability when inflation and unemployment respond to economic shocks in different ways, which is unacceptable in the context of monetary stimulation for the development of the smart industry. The analysis identified the advantages and disadvantages of all models, which allowed us to objectively assess the actual conditions of the models. The analysis has shown that, given the above shortcomings and the specifics of the current economic environment, the Cobb-Douglas model is the most effective for analysing and forecasting the development of the smart industry in Ukraine. The other models considered may also be useful for stimulating the development of the smart industry, but they do not provide the same flexibility and ease of use as the Cobb-Douglas model. Thus, given the specifics of monetary policy, the Cobb-Douglas model seems to be the most appropriate tool for analysing and forecasting monetary stimulus for the development of the smart industry in Ukraine. It allows for a wide range of production factors and is simple to analyse and interpret the final results, making it the most suitable for addressing complex issues of monetary stimulation in the context of smart industry development.

The article presents the constituent elements of the system of financial and economic stimulation of the development of smart industry (and scientific and technological progress in general), the main of which are defined as monetary (monetary and credit) and fiscal (tax and budget) stimulation. The results of the analysis of the currently existing economic modeling software systems, which can be used to determine directions for stimulating the development of smart industry, are given. Such modeling software products included: "Energy Policy Simulator" system by the Energy Innovation Policy & Technology Institute, "Siforeca" industrial forecasting and foresight system by the Institute of Industrial Economics of the National Academy of Sciences of Ukraine, Global Industry Model by Oxford Economics consulting company, the Global Economic Data & Forecasts system from Moody's Analytics consulting company. Features of governmental practical measures of foreign countries for the financial and economic stimulation of the development of smart industry are also given, which include: the EU Industrial Research and Development Investment Scoreboard; Inflation Reduction Act (USA); the New Industrial Strategy of the EU; practical mechanisms for stimulating smart industry in China; Japan's government initiatives to stimulate the development of smart industry. The analysis of the policies for stimulating the development of smart industry in the countries and regions that are leaders in this area (the USA, the EU, China and Japan) made it possible to establish that there is fierce competition between the leading countries -- they are trying to secure leading positions in the field of specific technologies and the market as a whole. The main tools for stimulating the development of smart industry are direct financial injections (from dedicated governmental funds) and tax benefits. The development of smart industry is closely intertwined with the environmental agenda, and governments are trying to direct investments in advanced technologies in environmental areas. The leading countries do not wait for market mechanisms to distribute investments in smart industry on their own, but make targeted efforts to stimulate such investments. The modeling tools can be used (and is already used) at all stages of the development and implementation of measures for financial and economic stimulation of the development of smart industry -- ranging from the selection of a specific stimulation tools to the determination of the volume of stimulation measures and directions of their application.

The article contains concepts of development for Ukrainian economy in the form of development explanatory basis. Such basis is important for defining development character, formalizing aims and principles of development, choosing its vectors and methods that implement such vectors into reality, building institutional support of development and effective employment of necessary resources. Using the general concepts of development studies, the content of notion "economic development" is specified. Difference between notions "economic development" and "economic growth" is considered. Via the qualitative features of general types of development, the character of development for Ukraine is suggested taking into account existing conditions and expected changes in Ukraine and abroad. It is shown that by the dynamics of changes development of the Ukrainian economy has to be revolutionary, by the vector -- intensive one (aimed to the emergence of qualitative changes with a stable character due to implementing new technologies and renewing the production asThe article contains concepts of development for Ukrainian economy in the form of development explanatory basis.

The objective of the paper is to define long-term factors and trends in the development of the world energy industry and their refraction to Ukrainian realities. The article consists of an introduction, three sections, namely: the main trends in the development of the global fuel and energy complex, analysis of the current state, long-term factors and trends in the development of the national fuel and energy complex of Ukraine. Conclusions end the paper. As for the world energy sector it is shown that its modern changes - Grand Transit - are due to the ideology of sustainable development and have the character of an extraordinary change in the technocenosis, the transition from the use of fossil fuels to energy from renewable sources, mainly - wind and photovoltaic nature. Along with the major tendencies of the Great Transition, there is also the trilemization and politicization of energy sector. Trilemization components are: Energy Security, Energy Equity and Environmental Sustainability. There are three scenarios for the development of the global energy - Unfinished Symphony, Modern Jazz and Hardrock, distinguished by the degree of greening and the availability of energy resources. Political motives are becoming more and more significant at all levels - from global to local. Major players are lobbying their interests, there is an activity of structures from the field of nuclear energy, powerful fuel companies, owners of gas transportation and gas distribution infrastructure. In Ukraine, transformation processes are taking place against the backdrop of low environmental acceptability and high depreciation of fuel and energy sector facilities and infrastructure, political and economic instability. The requirements of decarbonization create challenges to the very existence of coal energy, which is the main component of the energy generating fund of the country and the regions, where mines are located. Options for the development of hydrogen/ammonia energy in the form of vertically integrated energy-chemical systems with the nuclear power plants and reformed coal-fired thermal power plants are considered as promising; energy diversification of mining regions; the creation of virtual power plants based on hydrodynamic water heating installations.

The paper deals with the study of long-term factors and trends of the Ukrainian steel industry development in the context of the influence of global industry trends. Its relevance is explained by the importance of the industry in the global and Ukrainian economy and the need to take into account modern economic, technological, social and climate challenges and opportunities for its future development. It was defined that leading factors of the world steel industry development in the long run are the demand for steel products, the implementation of latest technologies and the strengthening of a state industrial policy. Their influence will manifest in the increase of steel products consumption due to population growth, the priority implementation of smart technologies to improve the efficiency of steel manufacturing and strengthening of a state support for the industry, in particular - through protectionist measures. The main long-term trends of steel industry development on a global scale, due to the action of these factors, are the change in the geographical and product structure of the world steel market towards the leadership of the Asian region and the use of high-strength steels; increasing the environmental friendliness of the industry in order to achieve climate neutrality as a result of the implementation of breakthrough technologies; an increase of GDP steel intensity due to rise of steel production, which demonstrates a rather strong position of the steel industry in the economy. The study showed a slight decrease in the role of such traditional factors of the steel industry development as prices for steel products, investments and raw materials due to the increasing importance of means and directions for using resources instead of their ordinary availability. It was established that the main factors of the Ukrainian steel industry development in the long run, which are basically identical to the world ones due to its excessive export orientation, are changes in the global steel market, the development of latest technologies and the improvement in the competitive environment. And long-term trends are changes of steel products demand, increasing the environmental friendliness of the industry and reducing the GDP steel intensity. The influence of these factors and trends is largely negative and may lead to decrease of the role of steel industry in the economy due to the country's significant lag in terms of the introduction of latest technologies against the backdrop of increased competition in the foreign market, the lack of an effective industrial policy in the conditions of underdevelopment of the domestic steel market, a possible decrease in demand for steel products in the context of a declining population and a decrease in metal production. The improvement of the situation will contribute by the enhancement of the competitive environment through the elaboration of a long-term strategy for the industry development in the form of a separate regulatory act, the activation of the national market, the development of fundamental and industry science for the elaboration of advanced technologies of Industry 4.0 and the support of state authorities in promoting steel products to foreign markets.
