Therefore, this study examined the impact of economic factors (inflation and gross domestic product (GDP) growth) and non-economic factors (social contribution and human capital) on the natural resources’ commodity prices in China. The secondary data from 1986 to 2019 was gathered and analyzed by E-views. The variance inflation factor (VIF) was run to examine the multicollinearity, Augmented Dickey-Fuller Test (ADF) to investigate the unit root, and autoregressive distributed lag (ARDL) model to test the linkage among variables. The results indicated that inflation, GDP growth, social contribution, and human capital positively link with natural resources commodity prices in China. This research provides the guidelines to the policymakers while developing policies regarding economic and non-economic factors and natural resources prices.

However, the 1994 exemption order of this specific processing industry in complying with the Atomic Licensing Act 1984 has directly impacted plant workers and environmental sustainability in terms of radiation safety. The radiological impact was indicated based on radiation exposure values that exceeded the regulatory limit of 1 mSv/y. Despite these findings, the industry's response to remedy the situation remains stagnant. Due to enforcement and awareness deficiencies, similar radiological risks were still elucidated in recent studies. Notedly, countries that enacted a series of comprehensive guides, laws, and heavy fines have successfully minimized the industry's radiological and environmental effects. Hence, in managing the local tailing processing industry in regard to conduct and risks to the workers and the environment, a robust set of comprehensive laws and regulations must be established, functioning as the foundation of future improvement.

However, the literature is unable to document conclusive remarks on it, specifically in African countries. Given that, this study is an attempt to disclose the link between natural resources, economic complexity, and economic growth. A sample of 24 African economies for the years 1995–2017 was analyzed with the implications of the system GMM (generalized method of moments) model. This research deals with natural resource rents and economic complexity as predictors of economic growth while controlling for corruption, gross capital formation, total labor force, foreign direct investment inflow, and trade openness. The empirical findings first document the negative impact of natural resource rents while the positive impact of economic complexity on economic growth. However, a positive link was observed when economic complexity interacts with natural resources and conjunctionally affects economic growth. The empirical analysis further supplements the dynamic impact of control variables on economic growth. This study strengthens the views of natural resource curse (in individual analysis) and natural resources blessing (interaction effect) hypotheses and calls for more focus by policy officials on economic complexity to harvest the advantages from available natural resources.

We focused on the long-term security dynamics in the context of resource constraints and the growing demand for electric vehicles (EVs) in China. We then simulated the impact of the short-term shock caused by the Coronavirus on the security of the domestic lithium supply chain. Based on scenario analysis, China's lithium supply chain exhibited prominent consumption-driven characteristics. Long-term changes in China's ultimate recoverable lithium reserves would not have a significantly impact on lithium supply chain security. Contrary to this, the development of the EVs industry would result in a significant increase in China's demand for lithium, which might adversely affect the security of the country's supply chain for lithium in the future. The domestic lithium supply chain was able to withstand the short-term impact of the Pandemic, but overcapacity was intensified as a result.

The results show the following: commodity prices and sovereign risk move in opposite directions. The impact of global commodity prices on sovereign risk differ across countries. Commodity price fluctuations have asymmetric effects on sovereign risk; for some emerging countries, large upward commodity price fluctuations reduce sovereign risk, whereas large downward commodity price movements have a limited impact. These results have potential implications for investors and policy makers regarding sovereign risk management decisions and the cost of funding of investment projects.

To do so, we use a decomposition analysis based on the logarithmic mean Divisia index to analyze the trends in patent families collected from the World Intellectual Property Organization Mining database between 2001 and 2016. The sheer number of patent families filed in the most relevant patent offices is decomposed from the perspective of three factors, namely: the priority of climate change mitigation technology in a country; the overall relevance of the mining, mineral processing and metals sector in a country; and the size of patent families from a country. These factors have a different impact in different country groups, depending on whether the mining and minerals sector plays a strong role in their economy or not, or whether they are a developed or developing country. We observe that the decomposed patent trend correlates well with important events that affect the mining and metals sector, for example, the Paris Agreement and the price trend of metals. We are able to draw conclusions on how CCMT is developing in the mining sector of different countries and use those conclusions to support policies that encourage the further development of CCMT.

Price pairs for those states with significant shale production, as well as for major consumption states, show a particularly high reduction in integration. However, the degree of integration has stabilized in recent years, especially after 2016. For state pairs with integrated prices, we show that it takes longer to correct any disequilibrium from the long-run price relationship during the shale boom, indicating slower information transmission. Pipeline capacity and distances play a key role in determining information transmission throughout the sample period, while production, consumption, and storage levels have become more important in recent years. The analysis suggests significant welfare gains from efforts to improve natural gas market integration, such as pipeline and storage capacity expansion projects.
查看更多>>摘要：? 2022 Elsevier LtdWe aim to investigate the static and dynamic time-frequency connectedness between energy and nonenergy commodity markets in China during COVID-19 based on Baruník and K?ehlík (2018) method. First, in this paper, we find that the short-term connectedness dominates the long-term one, and the total connectedness increases after the COVID-19 outbreak. Second, the energy commodity is the receiver and is influenced much by the spillovers of non-energy commodity markets (e.g. chemical commodities and non-ferrous metals) in the short run. At the same time, the impact is less at the long-term investment horizons. In addition, chemical commodities and soft commodities are the primary transmitters in this system in the short run. In contrast, chemical commodities and coal steel iron commodities are the main long-run primary transmitters. Third, the spillover role varies with the time-frequency domain during COVID-19. To be more specific, the energy commodity shows a net receiver role in the short and long run before the COVID-19 pandemic, but after it, the role of the net transmitter can be seen in the long run with ease. Finally, we show that COVID can reduce the hedging effectiveness at different investment horizons. The mineral policymakers should note our dynamic empirical results between energy and nonenergy commodity.

The comprehension of the asset returns and risk has played a main role in managing returns for the world market. The energy portfolios present challenges as they are highly volatile. The present study is concerned with evaluating and describing the joint return of energy-related commodities in the Indonesian market. Power, oil, coal, gas, and carbon are the main commodities being considered. The study presents the empirical evaluation of the returns from the multivariate hyperbolic distributions. Also, the study presents the method with which the risk measures can be evaluated for the commodity portfolios based on the generic assumptions of the hyperbole. The study's main findings are that the estimates of risk based on the normal distribution have statistically significant hyperbolic distributions. These are flexible and include accurate estimates of risk. The study indicates that the carbon allowances can be used to risk exposure for a typical energy portfolio for a power plant.

It entails a sizeable investment in human capital to foster more conscious efforts to limit carbon emissions. Therefore it is critical to evaluate the nexus between carbon emissions and human capital efficiency. This paper analyzes the link between human capital efficiency and carbon emissions using a comprehensive sample of 5740 firms across eight countries spanning over ten years. Our findings show a negative relationship between investment in human capital and carbon emissions. We emphasize that optimal human capital efficiency can help limit emissions by fostering the transitions to renewable energy sources and the development of cognitive appreciation. The results remained robust for periods marked by booming and receding oil prices. These findings have important implications for optimizing firm performance while preserving sustainable development goals.
