An important place in the system of study of sustainable economic development of the region is an objective assessment of thecomponents of its budgetary potential. The process of assessing the budget potential consists of two parts: analytical and accounting. The analytical part of the estimation of the tax component of the budget potential is to study the structure and dynamics of revenues from taxes and levies to local budgets, and is a prerequisite for the calculation part of the assessment. The estimated part of the estimation of the tax component of the budget potential of local finance involves the calculation of indicators, which include: the coefficient of elasticity of tax revenues mobilized to local budgets; tax rate of local taxation; Herfindahl – Hirschman index for local taxation and the tax revenue concentration factor. The assessment of the tax component of the budgetary potential of local finance in Ukraine and the Rivne region shows that 85% of the tax component forms income taxes and, first of all, personal income tax and local taxes and fees. Positive factors that influence the increase in income from personal income tax are: an increase in the tax rate to 18%; increase of the minimum wage and corresponding growth of the wage fund; the trend of nominal GDP growth. Negative factors that reduce the level of tax component of the budget potential of local finance are: underselling taxpayers and tax evasion; enrollment of personal income tax to the corresponding local budget at the place of registration of a legal entity; reduction of the tax base due to the reduction of the general level of incomes of the working population and the deepening of poverty. The results of calculations of the above-mentioned factors indicate the need to reduce tax pressure on the real economy sector, while preserving opportunities for social tasks and the possibility of expanding fiscal policy instruments at the local and regional levels. В статье исследована динамика и структура формирования налоговой составляющей бюджетного потенциала местных финансов. Проанализированы расчетные коэффициенты, определяющие эффективность налоговых поступлений для развития экономики региона.

Evaluation of different lighting sources on the growth and chemical composition of lettuce

ArticleExperiment were carried out in Latvia University of Agriculture in plant growth room. Lettuce Lactuca sativa L. var foliosum cv. ‘Dubacek’ and L . sativa L. cv. ‘Michalina’ were grown under 4 types of lights (luminescence lamps, commercial light emitting diodes (LED) lamps (V - TAC premium series – for plant growing) and two different Lumigrow LED strips - dominant wavelength - blue or red with 14 h ph otoperiod and total photosynthetic active radiation (PAR) 100 μmol m - 2 s - 1 in all variants. Plant weight, length, amount of leaves were measured. Content of chlorophylls, carotenoids, phenols, flavonoids in lettuce was determined three times per vegetation period. In experiments were found that higher lettuce yield was under commercial LED (V - TAC premium series), but these plants contain less soluble sugars, pigments and phenols. Better plant quality was obtained with luminescence lamps. These lettuces have higher sugar, phenols and flavonoids content. Lettuce growth under blue dominate LED (LEDb) was delayed, but these plants contain higher chlorophylls content. The differences in plant growth, response to light and biochemical content b etween cultivars wer e detected

One of the defining components of ensuring the stability of the financial system is the sphere of public finances, because problems with ensuring the filling and balancing of the budget can have a significant destabilizing effect on the socio-economic development of the country. The purpose of the study is to generalize existing approaches to determining budget security, as well as to assess its impact on the stability of the country’s financial system.Financial stability is the state of the financial system, in which it is able to properly perform its main functions, as well as withstand crisis phenomena. The article examines the theoretical aspects of the concept of "budgetary security", by which we understand the state of ensuring the solvency of the state, taking into account the balance of revenues and expenditures of the state and local budgets and the efficiency of the use of budget funds. The impact of budgetary security on the financial stability of the state is substantiated. The indicators that determine the level of budget security are singled out: the amount of revenues and expenditures of the consolidated budget, their structure, the size of the budget deficit and sources of coverage, the level of redistribution of GDP through the consolidated budget; the amount of payments for servicing the state debt incomparison with the revenues of the State Budget.An assessment of the level of the country’s budget security for 2019-2021 was carried out and conclusions were made about significant threats to the budget system, in particular: the deterioration of the dynamics of tax revenues as a result of military actions, compared to the planned indicators; growing budget revenue losses from tax incentives provided to stimulate the economy; deterioration of payment discipline and growth of taxpayers’ tax debt against the background of deterioration of business activity; increase in budget expenditures for defense measures; growth of the budget deficit and public debt beyond economically safe limits. Proposals have been made to increase the level of financial stability in the budgetary sphere. У статті узагальнено існуючі підходи до визначення стабільності фінансової системи.

The solution to the problem of forming internal sources of investmentis impossible without the mobilization of free monetary resources of thepopulation. Therefore, the urgent task facing the domestic economy is the accumulation of free money of the population, the development of aneffective mechanism for their transformation into an investment resource to ensure long-term lending to the manufacturing sector.The purpose of this article is to substantiate the theoretical andpractical principles of the formation of savings and their impact on theinvestment potential of the country. The article considers the theoretical and methodological aspects of the formation of the investment potential of the country, which means the process of formation and effective use of own and attracted investment resources. Internal, external and mixed sources of investment resources formation are singled out. It is determined that the savings of the population are part of the income that remains in the form of temporarily free money after the implementation of consumer spending. It is noted that savings should be considered as capital that is used to increase income in the future. The classification of savings depending on the forms (organized and unorganized) and financial instruments. Financial instruments in the organized form of savings include bank deposits, government and corporate securities, insurance policies, investment fund certificates, pension contracts.The preconditions for the formation of frugal behavior of thepopulation are analyzed and it is established that the need for investmentresources is growing in the country and there are opportunities to meet this need at the expense of domestic sources. The structure of capitalinvestments by sources of financing is investigated. It is determined that the largest share of capital investments is financed by own funds of enterprises and bank loans. The dynamics of the main bank reserves has been analyzed and the degree of security of credit funds by deposits has been determined.Proposals to improve the mechanism of population savings in order toincrease the country’s investment potential have been provided.В статье рассмотрены теоретико-методические аспекты формирования инвестиционного потенциала страны.

НЕОБАНКІНГ ТА ЦИФРОВА ТРАНСФОРМАЦІЯ БАНКІВСЬКОЇ СИСТЕМИ УКРАЇНИ

In the article the main features of the digital transformation of the domestic banking system are highlighted. The analysis of the current state of penetration of innovative banking technologies is carried out. In particular, it shows an increase in non-cash payments, an increase in the issue of contactless and toned payment cards with their further integration into international payment applications and financial markets, especially cryptocurrency markets. The study also summarizes the strengths and weaknesses of the operation of neo-banks.As a result, the article includes proposals for the formation of the banking sector digital transformation priority goals in the context of digital economy development, and measures for their implementation. Primary, this is, the banking ecosystem creation that distinguishes the digital form of data as a key factor of added value and ensures effective interaction of the financial system participants, both within the country and with other countries. In consequence, the implementation of the concept of open banking should become an incentive for the development of a new type of banking system. Finally, we came to the opinion that, it is necessary to create an institutional environment for the creation and development of high-tech banking and increase competitiveness both in the field of individual banking services and the banking system as a whole. The creation of institutional and infrastructural environment should be facilitated by the creation of incubators and accelerators, as well as regulatory sandboxes, as they allow to test innovative proposals on the market with real consumers under the supervision of the regulator. All things considered, it willcontribute to the emergence of new financial startups, expanding the range of payment market participants and the development of new products and services. Obviously, it will allow consumers to get truly competitive and high-quality payment services and high protection of their rights. В статье выделены основные отличительные черты цифровой трансформации отечественной банковской системы.
