Retraction Note: Numerical simulation of sea surface temperature based on big data and calculation of economic effect of import trade

The Arctic Oscillation and the North Atlantic Oscillation are the dominant patterns of the atmospheric circulation except the tropics in the northern region. In winter, the Arctic Oscillation and the North Atlantic Oscillation have a great influence on the climate of most regions except the tropics, and it has an organic integration with the North Atlantic sea surface temperature. It is still used by many departments and institutions to judge and predict atmospheric circulation according to the set sea surface temperature. However, the short-term climate judgment is greatly affected by different sea surface temperatures, and the understanding of the otherness is still lacking. Therefore, it is the main way for China to predict the climate of relevant regions through the prediction experiments of several different sea surface temperatures for atmospheric circulation climate carried out by the National Climate Center and the analysis of relevant data information through the experiments. It is still the main way to strengthen the development of trade, especially the development of import and export trade, by reducing tariffs. But it is inevitable that the reduction of tariffs will also reduce the country’s government revenue. By studying the impact of tariff reduction on finance on the basis of theory, to enhance the level of fiscal revenue of each country. Import trade is the main content of international trade, and its scale and form have a significant impact on the development of a country. Research shows that we should strengthen the import of high-tech products. Improving the import structure of general products and paying attention to the import of consumer goods play a very important role in stabilizing the country’s economic growth level and improving the country’s economic income.

Effective Cluster Model of Thermal Power Company Management

The aim of this study is to determine the need for cluster formations; to identify the influence factors on the creation of a cluster of thermal power companies in Poltava region. The method of evaluating the efficiency of formation of this cluster has been developed.The methodological framework of this research is general scientific dialectical method of cognition, in which the research object is studied as a dynamic system in the process of its development. The formation of the main directions of thermal power company development was carried out on the basis of dialectical, historical and systematic methods. In the process of studying and generalization of scientific and practical development methods of comparison, analysis and synthesis, induction and deduction were applied. Also the study is based on regulatory and economic instruments, economical studies and studies of scientific research institutions.As a result of the study the main participants of the cluster formation were identified. So it may be comprised of the members of the cluster, generating thermal energy, the thermal energy consumers and the region where the cluster of thermal power companies will be formed. According to the participants of cluster associations the factors of influence on economic and social effect from implementation of the cluster thermal power companies in the Poltava region were formed. We determined that to reduce the rate for thermal energy it is necessary to conduct a number of activities. The application of the proposed measures will significantly reduce the services cost of thermal power companies. The cost of thermal energy and the distribution among the participants of cluster associations were calculated on the example of Poltava region utility production enterprise of heat economy "Poltavateploenergo". The participants are heat producers, transport companies, distribution and heat supply companies, repair work companies, construction work enterprises. It is established that the overall effect of cluster members has both quantitative and qualitative nature. The impact on consumers is qualitative. It is based on the fact that the tariff for consumers remained unchanged in the medium term (five years). The essence of economic effect is in the quality and timeliness of services thermal management. The overall effect of its work influences all members. It occurs when there is the formation and implementation of cluster thermal power companies.But in addition to the advantages of cluster associations its major problems were presented in the work. Among them there are the following problems: the lack of informativeness of executive authorities and business representatives in the application of the cluster approach; the lack of public policy to ensure the systematic approach and organization of interaction between different levels of executive authorities in the implementation of cluster projects; lack of institutional and financial support to cluster initiatives; lack of trained personnel in the organizational aspects of cluster technologies; the lack of effective methodological base for the application of cluster technologies. Scientific novelty of received results is the development and calculation of economic effect from the formation of a cluster of thermal power companies both at the regional level and at the level of the enterprise and the consumer.

The programme of renovation is adopted for the period up to 2032 and it will allow eliminating the imbalance of development of the urban environment, which is saved up for the last decades, on the other hand it will prevent mass emergency housing estate in Moscow in the next 10-15 years. Updating of the housing estate is to be based on the development of infrastructure, on the creation of additional conditions for human development, on the ecology, providing complex development of the territory according to the modern requirements to the urban environment. The economic efficiency of renovation of the housing estate will be estimated with the use of indicators of increase in the consumer quality of apartments, blocks of flats, residential districts. The method of calculation of economic effect of renovation before delivery of inhabited and non-residential premises for rent is developed for the definition of payback period and the potential monthly cost of the rent after renovation of buildings. The offered method allows estimating the efficiency of organizational actions of the state programme and it is only a part of assessment of the overall economic efficiency. The offered technique of assessment of economic efficiency of renovation will allow making economically reasonable decisions during various stages of city-planning activity: during preliminary preparation, during planning of the territory, during development and the approval of the design and estimate documentation.

THE STUDY OF EFFECTIVENESS OF THE MANAGEMENT OF ENTERPRISE IN THE ASPECT OF OPTIMIZATION OF TAXATION ON EXAMPLE OF AMORTIZATION POLICY

The questions of tax planning as the one of conditions of effective development of native enterprises were studied. Despite the fact that in theory the taxes must not manage the whole activity of enterprise and essentially change the philosophy of business, on practice taxes are the powerful instrument of economic regulation, completely influence the degree of strategic decisions, compel leaders to change the tactics of enterprises actions cardinally. The analysis of the influence of accounting policy on tax commitments allows make a conclusion that the methods of costs accounting, methods of amortization charging, variants of valuation of assets and debts, possibility of creation of the reserve funds influence the reflection of the results of enterprise activity in financial reporting and, correspondingly, the value of taxation base. That is why their correct choice would help to the leaders of enterprise to choose the necessary levers of tax planning for optimization of taxation. The elements of accounting policy that influence or can influence the tax commitments on the example of accounting of the fixed assets are considered. The algorithm of calculation of economic effect in the result of the use of mechanism of accelerated amortization of the active part of fixed assets on the base of given value of money was offered and the influence of the part of surplus value on the choice of tax system was analyzed on the example of formation of enterprise amortization policy. The elaborated algorithm of tax optimization allows mobilize the additional investment resources of economic subject and decrease the tax load. The offered calculation of the value of economic effect relative to the cost of each group by operation life has a great practical importance, because it demonstrates the sum of profit, lost at the end of service term of each group depending on operation life.
