Development in harmony with nature is a fundamental social paradigm, the realisation of which depends on fulfilment of basic conditions, namely preservation and restoration of the the natural environment as well as ensuring the ecologically safe functioning of ecosystems. There is a need to find a compromise between the social and economic needs of mankind and the potential of the biosphere to satisfy them. At the present stage of development of society, the tools based on economic interest are the most efficient for the effective use, preservation and restoration of ecosystem functions. The economic contributions of ecosystems are not fully taken into account in the modern economy. This is largely explained by the lack of a coherent scientific approach to defining their nature and lack of methodological tools for their economic evaluation. In this regard, the need arises for undertaking appropriate scientific research and the inclusion of ecosystem services in the activities of business entities. The concept of ecosystem services is based on the need for co-evolutionary development of environmental and economic components. There is no single approach to implementing the concept of ecosystem services that would meet the environmental conditions of every geographical site. Generalisation and systematisation of the provisions of the concept of ecosystem services, verification of the basic mechanisms and their adaptation to the legal and regulatory framework in Ukraine, examination of the conditions of ecosystems and their economic value are necessary for the implementation of the ecosystem approach in the sectors of the Ukrainian economy. The objective of the study is to characterise the progress of development and implementation of the concept of ecosystem services in Ukraine; to define and characterise the ecosystems in Ukraine that are particularly important for the provision of ecosystem services. Scientific principles and consistent patterns in the field of ecology, geography and landscape science provided the methodological basis of the study, which was based on a systematic approach. The cartographic method (based on GIS-technologies), the method of expert estimations and the statistical method were used. ArcGis and Mapinfo Professional software products as well as Google satellite images and electronic vector layers of a topographic map of Ukraine with a scale of 1:200,000 were used to calculate the area of ecosystems within landscapes and create cartographic material. Statistical and cartographic materials, reports from research institutions, regulatory and reference materials, scientific papers written by domestic and foreign scholars provided the information basis of the study. Scientific papers on the classification of ecosystems, ecosystem services and the implementation of the concept of ecosystem services in Ukraine have been analysed. The categories, size and area of ecosystems in Ukraine that are of particular importance for the provision of ecosystem services have been defined, their ecological condition has been assessed and the prevailing ecosystem services have been identified.

The paper considers the problem of studying the impact of key determinants on the industrial enterprise business model economic efficiency and aims to build an optimal model for predicting the industrial enterprise business model effectiveness using neural boundaries. A system of key determinants key factors has been developed. Significant factors were later used to build neural networks that characterize the studied resultant trait development vector. The procedure for constructing neural networks was performed in the STATISTICA Neural Networks environment. As input parameters, according to the previous analysis, 6 key factor indicators were selected. The initial parameter is determined by economic efficiency. According to the results of the neural network analysis, 100 neural networks were tested and the top 5 were saved. The following types of neural network architectures, multilayer perceptron, generalized regression network and linear network were used. Based on the results of the neural network modeling, 5 multilayer perceptrons of neural network architectures were proposed. According to descriptive statistics, the best model was a multilayer perceptron, with the MLP 6-10-1 architecture, which identifies a model with 6 input variables, one output variable and one hidden layer containing 10 hidden neurons. According to the analysis of the sensitivity of the network to input variables, it was determined that the network is the most sensitive to the variable the share of electricity costs in total costs. According to the results of selected neural networks standard prediction, the hypothesis of the best neural network was confirmed as Absolute res., Squared res, Std. Res for the neural network MLP 6-10-1 reached the optimal value and indicate that the selected model really has small residues, which indicates a fairly high accuracy of the forecast when using it.

Innovative policy and regional management leverages should create the foundations for the “impulse” to form the Ukrainian market of natural gas and its distribution. Efficient and desirable economic reforms in the activity of the gas distribution companies of the Western region of Ukraine will contribute to increasing their competitiveness level by implementing innovative activities. The paper aims to make an integral estimation of the competitive positions of the gas distribution companies that function on the Western Ukrainian market of natural gas distribution among consumers and develop practical recommendations directed at forming and implementing the innovative policy of improving their competitiveness. To achieve the aim, the authors have developed the methodology of calculating the competitiveness level for the gas distribution companies that function on a certain natural gas distribution market of any scale. Based on the results of the conducted research, the paper shows that the competitiveness condition of most gas distribution companies of the Western region of Ukraine is either of critical – І or satisfactory – ІІ levels. Meanwhile, it is worth mentioning that only AT “Chernivtsihaz” is characterized by the highest rate of competitiveness integral estimation among all the companies operating on the market of the natural gas distribution among consumers in the Western region of Ukraine. Therefore, it was identified as level ІІІ – “decent” level, which is the average competitive indicator.

Researched the break-even activity processes of enterprises. Results showed that for certain types of activities there is no single traditional break-even point, there is a whole range of production volumes, which has the principles of break-even activity. Taking into account these aspects, it is proposed to improve the method of calculation of break-even points. Based on the application of averages theory and deviations analysis, calculated the minimum and maximum break-even point. These calculations allowed to simulate the equation of integration's lines. Determined the area of the zone of general activity, the break-even zone, the zone of losses, the zone of profits and the zone of financial security using the properties of a certain integral. To assess the efficiency of enterprises, proposed to determine the share of each of the zones in the total area of the enterprise's activity. The value of the calculated shares will allow to identify the bottlenecks of the enterprises's activity and determine the ways of increasing the efficiency of the activity, to optimize the activity.

The existence of an effective financial and economic security system, which will provide the protection of the enterprise from the threats is one of the most important aspect of sustainable business growth providing and formation of positive results of its financial activities in modern conditions of the economic processes imbalance. The protection is conditioned by the ability of the enterprise authorities: to provide sustainable business growth of the enterprise, to neutralize the negative impact of the crisis economy, to form an adequate accounting system of financial flows, to strengthen operating effectiveness of the control system, to provide the protection of the trade secret information confidentiality on appropriate levels.Modern scientific researches indicate there is impossible to find exit from crisis, to stabilize the economic situation, to create an effective mechanism of doing business without unified system of business financial and economic security. The search of the main ways of business acceleration with minimal expenses for forming of effective system of enterprises functioning aimed at maximization of profits and harmonization of relations between business stakeholders is very relevance in the conditions of post-crisis reconstruction.It should be taken into account the fact that production and economic systems, regardless of the form of ownership, are characterized by the presence of constant risk and threats associated with the dynamics of the external and internal environment of their functioning. The financial and economic security of a business depends on the state of the country's monetary security. It should also be noted that at present the financial security of Ukraine is under threat, since all components of ensuring financial and economic security are in danger. The problems of their own economic security arise before each type of business, not only in times of crisis, but also when working in a stable economic environment, the set of targets to be solved in this case has a significant difference.The instability of the economic and political situation in the modern world creates great tensions and serious problems to ensure the financial security of enterprises, which is associated with solving economic and legal problems, as well as protecting economic interests and property rights of economic entities -physical and legal persons.The financial security of the enterprise, as the main economic entity of the modern economy, occupies an important place among the indicators of financial security at other levels, as the security of the enterprise is the basis of both economic security in general and financial security in particular.Financial security plays a significant role in the management of the enterprise, helps protect its financial and economic interests from negative internal and external threats, protects the financial interests of business owners, controls the financial resources of the company, able to withstand existing and emerging risks that cause financial damage change t...
