Agricultural business depends not only on financial and economic factors, but also on natural and climatic conditions, which necessitates continuous development, which is based on adaptation to unpredictable and random conditions of the internal and external environment. The goal is to develop a methodological approach to assessing agricultural business system flexibility, which will provide an opportunity to study the ability of agricultural producers of various sizes to adapt to unpredictable changes, taking into account the internal and external environment. On the basis of a comparative analysis of modern approaches to the definition of flexibility, a definition of the concept of "flexibility of business systems" is proposed. The method of evaluation of agricultural business system flexibility has been developed that includes operational, structural, and strategic flexibility.

The transformation of modern scientific paradigm requires the adaptation of traditional theories of the firm competitiveness to new economic conditions. The aim of the study is to develop conceptual principles of enterprise’s competitiveness management, which are based on the definition of this term and includes a system of principles, functions, models and management mechanism. Formation of the concept involves the use of systematic approach to research. Principles of management by enterprise's competitiveness are allocated based on purpose of management, managed, managing systems and their interaction. Functions are determined by following stages: achieving the goals, developing of management system, aims to ensure competitiveness, characteristic of administrative actions. Model of control the competitiveness reflects the flows of management information and control system (administration unit) and manageable (economic process of the enterprise). Control mechanism includes appropriate methods (economic and psychological), levers (price, quality, brand, branding, logo, motto) and incentives (economic, moral, administrative, creative).

A high level of flexibility is an essential condition for the long and efficient functioning of agricultural enterprises in an uncertain environment. Flexibility is the ability of business entities to predict and timely and adequately respond to external challenges. The aim of the study is to assess and analyze the level of flexibility of agricultural enterprises in the Zhytomyr region, for which it is necessary to develop a methodology for quantifying the level of flexibility of agricultural enterprises, implement it on the example of manufacturers in the Zhytomyr region, assess the relationship between the level of flexibility and size of an agricultural enterprise, and group agricultural enterprises and regions in terms of their flexibility. The study proposed a methodological approach to assessing the level of flexibility of agricultural enterprises, providing for the assessment of operational, structural and strategic flexibility. The methodology is based on measuring the ability of manufacturers to quickly restructure their business activities during financial and economic crises. It is proved that a relatively high level of operational flexibility coefficient and insufficient levels of structural and strategic flexibility coefficients characterize the majority of enterprises in the Zhytomyr region. It was established that the levels of flexibility in agricultural enterprises of various sizes do not significantly differ from each other. A cluster analysis of the regions of the Zhytomyr region in terms of the flexibility of agricultural producers was carried out. It has been proven that more than 50 % of enterprises are characterized by low levels of all flexibility factors, and about 43 %by low structural and strategic flexibility coefficients and a high level of structural flexibility. In the following studies, attention should be focused on the search for mechanisms to strengthen the flexibility of agricultural enterprises based on statistical modeling methods.

Purpose. The purpose of the article is determining the possibilities of fractal approach, as the one that enables not only flexibility and viability, but also, management efficiency improvement, new competencies of the company formation, self-renewal ability formation and conflicts of interest between structural subdivisions in complex vertically integrated structures elimination, to the organization of implementation of organic business entities. Methodology / approach. The methodological basis of the research is general scientific and specific methods of economic phenomena and processes cognition. Therefore, the following methods have been applied: logical generalization (in determining the properties and benefits of agricultural business systems of the fractal type); comparison (when the practice of functioning of properties of organic products is analyzed); abstract-logical (when features of the functioning of network structures in fractally organized business systems are designed); monographic (in the study of the recent concepts of the functioning of fractal organized business systems); graphic (for visual presentation of the cooperation network of vertically integrated structure members); heuristic (when formulating conclusions and generalizations, as well as when justifying the directions for future research of the business system). Results. The essence of fractal business organization and the properties of fractal type business systems have been identified which include heterarchy, structure complexity, self-organization, self-optimization, openness, as well as autonomy and elements. The fractally organized business systems benefits in agribusiness compared with agrarian business systems with a traditional structure and management system have been determined. The existence of objective prerequisites for organic farms fractalization has been substantiated, which is already inherent in some of fractally organized business systems properties. The properties and features of fractally organized business systems of network structures functioning have been defined. Originality / scientific novelty. For the first time the substantiation of fractal type business systems formation in agriculture is proved, organic production in particular (previously expediency of fractal type business systems was studied only for industrial enterprises use). In particular, potential subjects of fractalization in organic production are identified, which include complex diversified agricultural business systems; the properties and advantages of fractally organized organic farms are identified and formalized, that are defined for a single fractal as well as a business system in general; the network structure of fractally organized organic farms is substantiated, particularly the relationship structure, network interaction rules, properties and values of fractally organized business structures in organic farming. In addition, the identification and formalization of the factors that affect Ukrainian organic production development got further development. Practical value / implications. To ensure the fulfillment of obligations by all parties as well as maintaining the basic principles of fractal organization in the field of goal-setting the function of the institutional environment is proposed. As PE “Gallex-Agro” is the vivid example of interconnections network that corresponds to the features of fractal business systems design, vertically integrated structure of member’s interaction network is designed at its case.

This scientific article is concentrated on the issues of evaluation of effectiveness of state regulation of the fixed capital reproduction in Ukraine using the methodology of taxonomic analysis. The study of modern economic literature has shown that scientists-economists have studied and explained numerous indices that allow evaluate the present day state of reproduction of the fixed capital. The authors propose their own approach to evaluation of effectiveness of state regulation of the fixed capital reproduction through the prism of the fixed capital reproduction process. That is, the authors made a detailed description of specific indices of effectiveness at certain stages of the process of reproduction of the fixed capital, which is presented in the summary table. Comprehensive effectiveness of state regulation of the fixed capital reproduction is determined using an integrated index that characterizes effectiveness of state regulation of the fixed capital reproduction using the method of taxonomic analysis applied for multidimensional economic concepts that are described by a considerable number of indices. Calculations proved instability of the taxonomic indices during the study period which, according to the authors, indicates a decline in the efficiency of reproduction processes connected with reproduction of the fixed capital in Ukraine.
