One of the obstacles to implementing innovations in mining is organisational resistance to change. Existing innovation models do not explicitly articulate the role of people and how to engage them in the process of implementing innovations and often do not recognise the specific context of the innovation activity. The nature of mining makes innovation adoption difficult because it involves changes to the mining operation, which impact the value chain. We use a qualitative exploratory approach based on 25 interviews with highly experienced mining practitioners to understand how the innovation adoption process unfolded in that context. Using an abductive approach, we draw from the empirical data and insights from the innovation and change management literature to develop an actionable process model for innovation adoption in the context of mining. The study makes important contributions. It articulates and validates a three-phased process model of innovation adoption, which explicitly incorporates a focus on the people who are active agents in the innovation process. The model is contextualised to mining in terms of language, practices, nature of the business and nature of innovation in that business.

Considering innovatively the spatial spillover effects of both green technology innovation and tax competition, the spatial econometric model and the threshold panel model have been incorporated to analyse the nonlinear impact of income tax competition and environmental tax competition on green technology innovation. Our empirical results reveal that (1) the green technology innovation of different regions exhibits a positive spatial agglomeration effect. Obviously, the Yangtze River Delta and the Beijing-Tianjin-Hebei region belong to the high-high region, while the western region belongs to the low-low region. (2) Income tax competition and environmental tax competition have an inverted U-shaped impact on green technology innovation in this region and neighbouring areas, but their thresholds are quite different. (3) There is regional heterogeneity in the nonlinear relationship between tax competition and green technology innovation, which can be affected by the level of economic development and the pollution emission levels. (4) In China from 2005 to 2017, the income tax competition in various regions was fiercer than the environmental tax competition. The conclusions are conductive to explaining the low efficiency of environmental regulations and provide theoretical guidance for policy makers to improve the green technology innovation system.

We regard economic uncertainty and dollar realized volatility as the low-frequency driving forces of the correlation movement. The findings are in favor of gold as a diversifier rather than a hedge for oil as the gold-oil long-run correlation on average is positive and not perfectly correlated. However, the negative gold-oil correlation observed after 2020 may cast new light in the field of study. We support that gold is a safe haven for oil market participants under economic uncertainty in the long run. We also suggest the oil market participants better reduce their gold holdings under the threat of dollar fluctuation.

To a certain extent, they are joint consumption, and the demand for lithium and cobalt in various countries has shown synergistic changes. In order to explore the complex relationship between cobalt trade and lithium trade, as well as the impact of low-cobalt technology development trends on the crucial metal of lithium batteries, this paper builds the multiplex cobalt-lithium trade network (CLTN) based on the global cobalt trade network and the global lithium trade network. We review the evolution of trade pattern of CLTN from 2010 to 2019, and explore the correlation between cobalt trade layer and lithium trade layer. Furthermore, the impacts of low-cobalt technology for lithium batteries on the CLTN are quantitatively analyzed. The results show that the globalization trend of CLTN is becoming more and more obvious, and the relationship between cobalt trade and lithium trade is getting closer. With the increasing shock of low-cobalt technology, the impact of the cobalt trade layer affected by technology on the lithium trade layer has become more and more obvious. Finally, some policy implications are provided for regulators to reduce trade risks.

Results as follows: (1) The ecological efficiency of the eastern region is highest, and western region is lowest. Most of the low-efficiency areas are concentrated in the west. Then the ecological efficiency of most areas in Chian has shown an increasing trend. (2) From the perspective of explanatory variables, there is a negative correlation between the overall national green finance and eco-efficiency, which is manifested in a non-linear "W-shaped characteristic; green finance and eco-efficiency in the central and western regions have negative correlation and "U"-shaped characteristic of non-linear relationship, but the east of China does not passed the significance test. (3) There is an inverted U-shaped relationship between the country's overall resource abundance and ecological efficiency. And it is not statistically significant in the eastern region, but it shows a significant inverted U-shaped relationship in the central and west of China. (4) The impact of FDI on China's regional eco-efficiency is generally positive. FDI in the central and western regions has negative correlation with eco-efficiency, but FDI in the eastern region is positively related to eco-efficiency; there are all negatively correlated in whole countey and regions between industrial structure and eco-efficiency; the level of regional economic development is generally positively related to regional eco-efficiency, and in the eastern region's eco-efficiency is positive, and the impact on the other two regions is negative.

Using the vector autoregression framework, this paper investigates the impact of oil price shocks, expressed in linear, asymmetric and nonlinear form, on real gross domestic product (GDP) growth in an oil-importing small open economy, i.e., Croatia, for the period 1995: Q1-2019:Q4. The results corroborate the presence of the asymmetric, nonlinear and direct short-run effect of oil price shocks on real GDP growth. A decrease in oil prices leads to a statistically significant increase in real GDP and its more volatile behavior, while an increase in oil prices causes a considerable drop in economic activity only in the fourth quarter. The oil-related policy shock variables, fuel market liberalization and fuel taxation, turned out to be insignificant predictors of GDP growth in an asymmetric and nonlinear model specification.

Current space law does not specifically address benefit-sharing, and substantial disagreement remains among States whose levels of economic and scientific development differ. A similar issue existed in the negotiation of benefits from other common areas, such as the deep seabed. This article addresses the regime for sharing the benefits from SM and the corresponding regime of the Area, namely the seabed and ocean floor and subsoil thereof, beyond the limits of national jurisdiction. In view of the current legal, political and commercial context, the article suggests that the regime for sharing the future benefits from SM should be voluntary and mutually acceptable based on a free-market approach while considering the interests of developing States. It also proposes a specific mode of such a regime based on three elements: (a) the form of the benefits, (b) the resource categories, and (c) the development stages. The study concludes that the present focus should be on collaborative development of technology to facilitate SM for the common benefit and interests of humankind.

Meanwhile, mining industry possess the feature of "high energy consumption, high pollution and high emissions". Especially in today's society where environmental protection is increasingly becoming the main theme, it has become an important issue for people to actively coordinate the relationship between mining and environmental protection, and promote the green transformation of mining industry. Combining industrial relationship and complex network, industrial complex network is applied to explore the industrial relevance, which is a perfect method to research industrial pattern. Based on the input-output data of China (1990-2018), this paper constructed the industrial complex network model to describe the evolution characteristics of Chinese industrial pattern. Then we focused on the mineral-related industries, to explore their role and position in Chinese industrial pattern by analysis of network overall and individual indicators and community division. The results show that Chinese industrial network has small world property, and the closeness of various industries is increasing, and the characteristic of industrial clusters ais obvious; The system of Chinese manufacturing industry is becoming more and more perfect and remains an important pillar and foundation of the national economy; Smelting and processing of metals industry plays an important role in connecting the preceding and the following. This paper provides a new perspective for the study of China's mining industry pattern and puts forward corresponding policy suggestions for the adjustment of industrial structure. At the same time, relevant development experience can also serve as a reference for subsequent countries.

An example is the overwhelming plunge in the prices of the assets being traded in most of these markets during the COVID-19 pandemic. The pandemic has raised market fear beyond what is historically known, thus calling for an empirical assessment of its degree of persistence. Interestingly, the issue of persistence in financial and commodity markets has not even been generally explored in the literature. Using fractional integration approaches, our findings show that all the considered market fear indices exhibit mean reversion before COVID-19 pandemic, implying that the effect of shocks is transitory. However, persistence is higher during the pandemic period, with fear indices of the gold market (GVZ), energy sector (VXXLE) and Eurocurrency market (EVZ) reaching the unit root zone. The Granger-causality test also reveals that equity market fear due to infectious diseases (EMV-ID) and global market fear (VIX) are responsible for the fear in virtually all other markets during the current COVID-19 pandemic period. Strong policy implications are associated with these findings.

Regardless of sectors, each company needs to be more focused on integrating such responsible activities into their activities. This intention is supported by several stakeholders (including shareholders, media, customers, authorities, etc.), who bring the sensitive sectors (which are more prone to society) to be more focused than ever on such responsible activities. Due to this pressure, in recent years there may be more evidence to integrate corporate social responsibility (CSR) into such sensitive sectors, including mining. Mining sectors often come under pressure from criticism from various activists because of their operational nature. Several studies attempted to integrate the elements of CSR into the mining sector through different perspectives. In a row, this study focused on issues of CSR in the mining sector with evidence of the Chinese case context. DEMATEL has been used to analyze the relationship between the collected common CSR problems. The survey results revealed that " Dangerous working conditions " (C8) and " Non-disclosure of confidential information " (C11) are the main most influential issues with CSR, which need to be addressed first and foremost to achieve effective CSR integration in the Chinese mining sector. As a groundbreaking work, this study focused exclusively on the human dimensions of CSR, which could help industrial leaders with more focus on humanrelated responsible practices in their mining sectors.
