The aim of this paper was to determine the mechanisms of climate change impact on the yield of the main exportoriented crops in the agro-climatic zones of Ukraine. The study of the problem of changing the acreage of the main export-oriented crops was conducted according to the data of the State Statistics Service of Ukraine on the time horizon 2000-2018 in the following order: first, the dynamics of the change of the acreage under corn, sunflower and wheat by the agro-climatic zones of Ukraine was analyzed; secondly, the trends of yield changes of these crops were investigated based on the increase in the difference in yields between the northern and southern zones; and, finally, the temporal and spatial expansion in the area of crop propagation were investigated by applying the panel regression method. The findings obtained indicate that the applied models confirm the assumption of the effects of climate change on crop yield changes and the zones expansion in the northern direction. If the country's wheat area can be considered stable (variation is insignificant), then the corn and sunflower areas have grown steadily under the influence of increasing demand from national and world markets. At the same time, the growing acreage under corn and sunflower occurred in all climatic zones. Stable expansion of corn crops in the north direction in all three agroclimatic zones of Ukraine has been statistically confirmed. The article presents the findings of empirical analysis, which confirm that if the boundaries of soil and climatic zones change, the conditions of growing crops and their yield will consequently change as well. Thus, based on current global forecasts, the impact of weather on Ukraine's agriculture will increase, and the most negative effects can be expected in the Steppe zone, where the likelihood of weather and climate risks increases, requiring the development of adaptation and mitigation measures as well as exploitation of new potential opportunities that are being opened. Studies have shown that there is an expansion in crops to the north and a change in their pattern, including a significant increase in the area under corn.

Purpose. The aim of the article is to identify the benefits of the chosen strategy of agribusiness (profit maximization, or yield maximization) based on the statistical observations of yields and production factors (fertilizers, plant protection products). Methodology / approach. To analyze productivity growth in grain production under the influence of innovative technologies the data of long-term observations of winter wheat yield in Germany and the United States were selected. In this paper, to analyze the prerequisites and prospects for stabilizing of the crop production, mineral fertilizers and plant protection products were selected as production factors affecting the yield of wheat. Methods of time series analysis and nonlinear econometric analysis were used to assess the impact of these factors. Long-term trends of growth of wheat yields in Germany, the USA and Ukraine were analyzed using regression models. The general model of agrarian business profitability in grain production is based on non-linear correlations of individual factors of intensification and panel regression. In order to substantiate the conclusions of the calculation, the estimation of climatic risks is used. For this purpose, dispersion methods, nonlinear optimization methodology are used. Results. Estimates of wheat yield fluctuations due to climate risks show that they will not significantly affect the problem of food security, so there is no need to impose restrictions on the export of wheat. On the choice of optimal strategy, based on analysis using econometric model of decreasing marginal utility of production resources, it is proved that the maximization of yields is achieved at lower costs than profit maximization. Originality / scientific novelty. The main contribution of the article to the level of application is to analyze the impact of production factors on wheat yield, taking into account climatic risk and reducing the marginal utility of production factors. At the theoretical level of the study, it represents a contribution to the discussion of the vectors of the optimal path of wheat production in Ukraine. Analysis of data on wheat yield variability in Germany and the USA showed correlation of profitability and risk (indicators of expected yield and its variance). However, this means that an increase in wheat yields in Ukraine will also increase its variability and therefore requires the implementation of a long-term strategy that can ensure stable growth. Practical value / implications. Based on the above calculations, it should be emphasized that the Ukrainian agrarian business (in particular, crop production) is developing its own way, not following the development path of Germany or the USA. However, some peculiarities of the development can be highlighted. After a rather long recession, the agricultural sector has embarked on a path of stable growth with an annual increase in wheat yields of around 1 hundred kg/ha. Furthermore, the extremely low proportion of forested land in Ukraine by European standards significantly increases the impact of weather and climate risks. Therefore, a further intensification of crop production while increasing the share of forested land at the expense of less productive land is probably the way to an ecologically balanced development of agriculture.

Purpose – the purpose of the article is to develop a conceptual model of the company’s financial logistics based on the system dynamics principles. Research methodology – the article is based on the system analysis and system dynamics methods to define, classify and simulate a company financial flow. Findings – the definition of financial logistics for a business system has been defined. The authors make a classification of the company’s financial flow by the main economic activities and time series factors. Research limitations – commercial data, used for the practical implementation of the model, are confidential and cannot be disclosed. Practical implications – the model is implemented by transformation of a system dynamic flow graph into VENSIM programs. It may estimate the stationary trajectory financial flow and short-term and long-term gaps. Originality/Value – the conceptual model of the company’s financial logistics is determined based on the system dynam-ics principles. The model includes the advantages of the financial management methods and contemporary econometric analysis instruments based on a system dynamics.
