Trading Mechanism

In recent years, in order to promote the consumption of new energy, many regions in China have carried out new energy market-oriented trading exploration, including direct trading of new energy and large users, new energy and thermal power generation rights trading, new energy cross-provincial medium and long-term trading, new energy cross-regional spot trading, and the establishment of a peak shaving auxiliary service market. This research takes typical new energy-rich provinces as an example to quantitatively analyze the effectiveness of the typical trading mechanism of new energy consumption in promoting new energy consumption. It is an inevitable trend to promote the consumption of new energy through market-oriented transactions. Combined with the construction process of China’s power market, the market will fully play the role of optimizing the allocation of resources, accelerate the construction of a power market-oriented trading mechanism that adapts to the consumption of new energy, and further utilize the market mechanism to promote new energy the role of energy consumption.

Statistical Indicators

The article proposes an improved system of statistical indicators for assessing the state and development of the fuel and energy complex of Russia, which defines a methodological approach to identifying factors and trends in its development. The introduction highlights the relevance of modernization of information and methodological support for reaching decisions on new tasks, including those related to the digitalization of the economy and implementation of the national projects’ portfolio. The body of the article critically examines the current configuration of official and departmental statistical information, based on which the authors selected 85 key indicators reflecting the state and development level of the fuel and energy complex of Russia. All of them can be delineated by sectors and analysis tasks. This evaluation system includes 7 blocks: general block characterizing the role of the fuel and energy complex in the economic system; key industry performance indicators; indicators of the production structure by industry; technological indicators of industries; prices for fuel and energy resources; production costs by industry; distribution indicators of fuel and energy resources. The paper analyses development trends in the fuel and energy sectors for 2008-2018. In particular, the authors’ research showed that modern oil production is characterized by a change in the territorial structure, as well as the reinstatement of the role of vertically integrated companies in the development of oil production. The article presents findings on the technological upgrading of Russian oil refining. However, the authors’ research proved that oil refining depth has ceased to be a reliable indicator of the level of technological equipment and modernization level of oil refineries. With regard to the development of the gas industry, there has been a steady increase in gas production, which is supported by maintaining a steady increase in demand for Russian gas in the domestic and foreign markets. The all-time high domestic consumer demand for gas fuel, associated with the Russian Regions Gasification Program implemented by the Ministry of Energy of Russia, was recorded. At the same time, the authors identified the main risk factors in the development of the industry related to Gazprom (a backbone of the energy sector) activities. The persistent positive growth dynamics in commodity production of associated petroleum gas was established. It was also noted that the highest percentage of its beneficial use is characteristic of operators of production sharing agreements. As for the results of the analysis of the coal industry, a matter of interest is the growth of domestic prices for coal products and related derivative trends. Particular attention is paid to the development of the possibilities of using over-the-counter coal price indicators. Replacement of coal with natural gas at a thermal power station in most regions of the country is of interest within the identified development trends of the electric power industry in Russia, which is explained by the environmental friendliness of electricity generation.

Background: China's power resources are unevenly distributed in geography, and the supply-demand imbalance becomes worse due to regional economic disparities. It is essential to optimize the allocation of power resources through cross-provincial and cross-regional power trading. Methods: This paper uses load forecasting, transaction subject data declaration, and route optimization models to achieve optimal allocation of electricity and power resources cross-provincial and cross-regional and maximize social benefits. Gray theory is used to predict the medium and longterm loads, while multi-agent technology is used to report the power trading price. Results: Cross-provincial and cross-regional power trading become a network flow problem, through which we can find the optimized complete trading paths. Conclusion: Numerical case study results has verified the efficiency of the proposed method in optimizing power allocation across provinces and regions.

Ancient India

Kautilya, a 4th century B.C.E. economist, recognized the importance of accounting methods in economic enterprises. He realized that a proper measurement of economic performance was absolutely essential for efficient allocation of resources, which was considered an important source of economic development. He viewed philosophy and political science as separate disciplines but considered accounting an integral part of economics. He specified a very broad scope for accounting and considered explanation and prediction as its proper objectives. Kautilya developed bookkeeping rules to record and classify economic data, emphasized the critical role of independent periodic audits and proposed the establishment of two important but separate offices - the Treasurer and Comptroller-Auditor, to increase accountability, specialization, and above all to reduce the scope for conflicts of interest. He also linked the successful enforcement of rules and regulations to their clarity, consistency and completeness. Kautilya believed that such measures were necessary but not sufficient to eliminate fraudulent accounting. He also emphasized the role of ethics, considering ethical values as the glue which binds society and promotes economic development.

This chapter discusses the role of energy in economic development, the transformation of energy markets, trade in energy resources themselves, and the geopolitical dynamics that result. The transformation of energy markets and their expansion via trade can help or hinder development, depending on the processes behind them and how stakeholders interact. The availability of renewable, climate-friendly sources of energy, domestically and internationally, means that there is no inherent trade-off between economic growth and the use of fossil fuels. The existence of economic, political, social, and geopolitical adjustment costs means that the expansion of international energy markets to incorporate alternatives to oil and coal is a complex balance of environmental trade-offs with no solutions completely free of negative impact risk. An understanding of the supply of and demand for energy must incorporate the institutional context within which they occur, as well as the social and political dynamics of their setting.

Abstract While the cost of sequencing genomes has decreased dramatically in recent years, this expense often remains non-trivial. Under a fixed budget, scientists face a natural trade-off between quantity and quality: spending resources to sequence a greater number of genomes or spending resources to sequence genomes with increased accuracy. Our goal is to find the optimal allocation of resources between quantity and quality. Optimizing resource allocation promises to reveal as many new variations in the genome as possible. In this paper, we introduce a Bayesian nonparametric methodology to predict the number of new variants in a follow-up study based on a pilot study. When experimental conditions are kept constant between the pilot and follow-up, we find that our prediction is competitive with the best existing methods. Unlike current methods, though, our new method allows practitioners to change experimental conditions between the pilot and the follow-up. We demonstrate how this distinction allows our method to be used for more realistic predictions and for optimal allocation of a fixed budget between quality and quantity.

Quantification of toxicity-induced cytomorphological effects in an epithelial cell culture system is described. Estimates of volume density and star volume of mitochondria and lysosomes are given. Mean volumes (n = 5) and coefficients of variation of these parameters were equal in experimental (TPA-treatment) and control cultures. An optimal allocation of resources for estimating cytomorphometric parameters would be to increase the number of culture flasks.
