Grey Prediction Model

Abstract Accurate prediction of energy consumption is an important basis for policymakers to formulate and improve energy policies and measures. In this paper, a new grey prediction model FDGM(1,1, tα ) is proposed. The grey wolf optimizer (GWO) is used to optimize the fractional-order r and the time power α in the model. A numerical example and four sets of solar energy consumption data (France, South Korea, OECD, and Asia Pacific region) are used to establish the FDGM(1,1, tα ) model. Based on the idea of metabolism, the solar energy consumption of the above four economies in the next 10 years is predicted. The results show that the FDGM(1,1, tα ) model is more reliable and effective than the other seven grey models. From 2020 to 2029, the solar energy consumption in South Korea, the OECD, and the Asia Pacific region will gradually increase; the solar energy consumption in France will slowly increase in the next few years and will gradually decrease after reaching a peak in 2026. The grey prediction model FDGM(1,1, tα ) proposed in this paper has strong adaptability and can be used not only for the prediction of solar energy consumption but also for the prediction of other energy sources.

Currently, the Asia-Pacific market is a priority goal for almost all major producers of liquefied natural gas(LNG). This is due to the relatively high price that local consumers are willing to pay, as well as the accelerated growth rate of natural gas consumption. At the same time, China is the main driver of growth in demand for LNGin the world, has concluded a trade agreement with the United States, which involves the purchase of energy resources worth more than $ 52 billion over two years. Given the decline in LNG prices, as well as increased competition, the issue of the prospects for sales of Russian Arctic gas on the market of the Asia-Pacific region becomes particularly relevant.The study provides a generalized assessment of the needs of the main importers of LNG ––China, South Korea and Japan, with a planning horizon of 4–5 years. The relatively high growth rates of the economy, partial rejection of nuclear energy, struggle to improve the environmental situation, as well as the desire to diversify supply routes explain the needs of the countries in the Asia-Pacific region for additional volumes of LNGin the near future. The analysis showed that both Japan and South Korea are interested in increasing the volume of imports of Russian arctic LNG, whose key advantages over most competitors are the price and relative proximity of sales markets. At the same time, the reduction in the number of operating gas drilling rigs in the United States indicates that it will not be possible to maintain the growth rate of LNG production at the level of 2018 and 2019.

Using the panel vector autoregressive (PVAR) model accompanied by the system-generalized method of moment (System-GMM) approach, this paper investigates the dynamic causality between participation in global value chains (GVCs), renewable energy consumption and carbon dioxide (CO2) emissions throughout 1990–2015 for 172 countries. The results show that participation in GVCs negatively causes renewable energy consumption except for the Middle East and North America (MENA) and sub-Saharan Africa. Second, except for the Asia–Pacific region and globally, participation in GVCs has no causal impact on CO2 emissions, and participation in GVCs has a positive effect on CO2 emissions in the Asia–Pacific region and globally. Third, except for globally and sub-Saharan Africa, CO2 emissions have no causal impact on participation in GVCs; however, CO2 emissions hurt participation in GVCs globally and in the sub-Saharan African region. Forth, renewable energy consumption positively causes participation in GVCs in MENA, while renewable energy consumption does not cause participation in GVCs globally and in other regions. Fifth, there is no causality between CO2 emissions and renewable energy consumption both at the global and regional levels. Several policy implications are proposed and discussed for promoting participation in GVCs and improving the environment.

As mitigating the effects of energy consumption on the environment is a crucial issue for the Asia-Pacific region, this study investigates the energy-environmental Kuznets curve (EEKC) hypothesis among the 19 Asia-Pacific countries. The study also tests the EEKC hypothesis for the low-, middle-, and high-income groups of the region. The panel regression and cointegration models are used for this purpose. Our test results of both models suggest that the EEKC hypothesis holds for the whole Asia-Pacific region. However, the test performed on the three different income groups revealed that the hypothesis only holds for the high-income group. The hypothesis was not apparent for the low- and middle-income groups. This indicates that the transition in the energy consumption along the EEKC is only occurring in the developed countries of the Asia-Pacific region and the developed countries need to support the developing countries to achieve economic growth along the EEKC.

Abstract The Asia-Pacific region is home to numerous island and maritime disputes but the Dokdo/Takeshima dispute is unique in that it involves two u.s. allies placing Washington in a uncomfortable position. u.s. policy has long been that it takes no position on sovereignty and will abide by any negotiated resolution of the dispute. Yet when tensions have flared between South Korea and Japan over the issue, there have often been calls for the United States to intervene and help solve the problem. However, any u.s. attempt to exert its leverage to reach a solution would be dangerous. Instead, Washington’s best course of action is to quietly remind both sides of their common economic and security interests while helping Seoul and Tokyo to manage the dispute in a careful and judicious manner.

Proposed Model

PurposeThe purpose of this study is to make a prediction of China's energy consumption structure from the perspective of compositional data and construct a novel grey model for forecasting compositional data.Design/methodology/approachDue to the existing grey prediction model based on compositional data cannot effectively excavate the evolution law of correlation dimension sequence of compositional data. Thus, the adaptive discrete grey prediction model with innovation term based on compositional data is proposed to forecast the integral structure of China's energy consumption. The prediction results from the new model are then compared with three existing approaches and the comparison results indicate that the proposed model generally outperforms existing methods. A further prediction of China's energy consumption structure is conducted into a future horizon from 2021 to 2035 by using the model.FindingsChina's energy structure will change significantly in the medium and long term and China's energy consumption structure can reach the long-term goal. Besides, the proposed model can better mine and predict the development trend of single time series after the transformation of compositional data.Originality/valueThe paper considers the dynamic change of grey action quantity, the characteristics of compositional data and the impact of new information about the system itself on the current system development trend and proposes a novel adaptive discrete grey prediction model with innovation term based on compositional data, which fills the gap in previous studies.

Adoption of the International Baccalaureate (IB) programs in the Asia Pacific region has accelerated at great speed in recent years, with one or more of its programs being employed in 158 countries in 5,284 schools worldwide. The growing interest of IB programs in the Asia Pacific region is largely due to its educational philosophy and progressive pedagogy that is appealing to many educators and parents who seek a high-quality education. However, various contextual and cultural factors need to be considered when it is being implemented within the national school system.
