The purpose of the work is to build a machine learning model that reflects the dependence of average consumer prices for drinking whole pasteurized milk with 2,5–3,2% fat content in the regions of the Russian Federation on indicators characterizing the production and consumption of dairy products, population size, and income. As a result, based on statistical data for 2016–2021. a model based on the gradient boosting algorithm was built. The significance of the model lies in the possibility of using it to identify and analyze the influence of individual regional characteristics (milk production, number of dairies, number of cows, milk yield, rural and urban population, per capita income, etc.) on average consumer prices for pasteurized milk in the regions RF. Understanding the factors in the formation of consumer prices on a regional basis is of practical importance for trading enterprises selling dairy products, as well as for dairy industry enterprises.","PeriodicalId":474181,"journal":{"name":"Èkonomika i upravlenie: problemy, rešeniâ","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135316727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, attention is drawn to the problems of preventing the bankruptcy of credit institutions in the modern conditions of the banking sector.

At the moment, the study of the causes of default, the assessment of the probability of its occurrence and the development of models for early detection of this event is of interest.

The proposed concept was tested using the example of choosing the location of a Korean cosmetics store in Belgorod. The study made it possible to determine the strategic factors of the attractiveness of objects: marketing (pricing policy, service and interior) and geographical (availability of parking, number of infrastructure facilities), digital (information processing of spatial data).

Along with this, they practically do not pay attention to the control of the actual cost of the state budget, the analysis of the reasons for exceeding the actual cost from the planned or saving actual costs compared to the planned ones. The actual cost price is always different from the planned (contract). Regulations provide for the possibility of adjusting the price of the state budget by the state. Very often, prices for raw materials, which is an exchange commodity, change. In this case, the adjustment is linked to the exchange indicators, and the actual price of a particular contract may differ significantly from the exchange indicators. Such an adjustment mechanism does not fully compensate for the losses of the enterprise from incorrect cost planning of the state budget. If the goods are not exchange-traded, but in fact there is an increase in prices for raw materials for the State Budget, regulations allow the adjustment of the price of the state budget on the basis of statistical data for similar raw materials. But in this case, the average prices will also be used, and not the actual one from a specific contract. The result is a conflict of interests between the participants in the implementation of the State Budget. The contradiction is solved not with the help of regulations, but with the help of contractual relationships at the stage of the next state budget. The interests of the parties to this conflict are not always fully satisfied. In order to harmonize the relationship in the chain of the customer (state) – contractor (enterprises), it is necessary to develop a fair mechanism for adjusting the cost of the state defense order, which will increase the motivation of enterprises, and allow the state to receive additional tax deductions.","PeriodicalId":474181,"journal":{"name":"Èkonomika i upravlenie: problemy, rešeniâ","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135660144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
