Technical innovation is a key factor influencing the supply of critical mineral. Past scholars have often overlooked the time lag effect of technological innovation and the heterogeneity and correlation of different technologies. Focusing on the critical mineral cobalt, this study combines social network analysis and the ARIMAX method to investigat...

Water and energy are mutually reinforcing elements in production and consumption activities, forming an inseparable relationship. This study, conducted at the provincial level, investigates the intricate connections between energy water footprint flow, water shortage, and water pollution. It aims to elucidate the vulnerability of provincial energy...

China is an extremely sensitive nation severely impacted by global climate change, with frequent floods in the Yangtze River Economic Zone causing severe socioeconomic losses and ecological and environmental issues. To investigate the potential industry-related economic losses and comprehensive hazards of flooding in the Yangtze River Economic Zone...

Analyzing the driving factors of PM2.5 pollution in different industries is of great significance for developing energy conservation and emission reduction policies in China's industries. In this study, the consumption-based PM2.5 emissions of China's industries are estimated by using an input–output model; on this basis, the generalized Divisia in...

Haze pollution poses a serious threat to residents’ health. In this study, a spatial econometric model of environmental health was established to investigate the direction, intensity, and spatial–temporal heterogeneity of the impact of haze pollution and its spillover effects on public health in 26 cities of the Yangtze River Delta urban agglomerat...

Based on patent information, the paper analyzes the technological comparative advantages from the perspective of industrial chain, and adopts the Social Network Analysis (SNA) method and knowledge production function model to explore technological innovation network structure of China's rare earth industry and its driving force. The results show th...

In recent years, severe air pollution has had a serious impact on the health and economy of residents and has attracted great attention. Due to the spatial separation between consumption and production, the transfer of PM2.5 pollution and its health and economic effects caused by interprovincial trade have not been taken seriously. In this study, e...

Currently, interprovincial trade and the industrial division of labor in China are rapidly developing. The end users of products are not responsible for their wastewater discharge but indirectly transfer their own wastewater discharge to production locations through trade flows. This undoubtedly exacerbates the burden of environmental governance at...

PM2.5 emissions has become a serious issue in China with enormous regional variation in economic development, resource endowment, and consumption patterns, which leads to great variations in regional PM2.5 emissions and embodied PM2.5 transfer among provinces. The spatial and temporal evolution pattern of PM2.5 and its influencing factors are impor...

Currently, preventing and controlling air pollution and inhibiting the excessively rapid growth of medical expenditures to reduce the living burden of residents have become a focus of general concern of society as a whole. It is of great significance to conduct an in-depth study of the relationship between air pollution and public health expenditur...

Achieving the coordinated development of mineral exploitation and the water environment (the mine–water system, MWS) is an urgent difficulty in the construction of China’s ecological civilization. Based on the theory of synergy, a synergetic model was used to construct a network of the MWS, and then, social network analysis was applied to study the...

China has become the leader in the wind energy industry and the “Belt and Road Initiative” provides a broad stage for China's international cooperation in this field. This paper examines the trade status of China's wind energy products in the “Belt and Road” countries, and measures the export potential and its determinants in the market of these co...

Increasingly serious air pollution poses a great threat to public health and daily life. Based on the Grossman China health production function, this paper examines the effects of the spatial agglomeration of Chinese public health and the spatial effects of air pollution and other factors on public health considering three aspects. This study emplo...

Coal is the widespread fossil fuel on earth. It provides the necessary material foundation for economic development of a country. However, coal mining activities cause a lot of environmental impacts that are hazardous to the health of citizens in mining regions and place costs on the government. According to government laws and regulations, coal mi...

This study aims to estimate carbon intensity abatement potential in China at the regional level by proposing a particle swarm optimization–genetic algorithm (PSO–GA) multivariate environmental learning curve estimation method. The model uses two independent variables, namely, per capita gross domestic product (GDP) and the proportion of the tertiar...

There are many logging parameters that affect identification of oil zones in the course of discrimination. A mass of redundant information exists. The identified precision and speed are impacted. Conventional methods cannot identify oil zones effectively. The method is put forward that information is optimised by rough set combining with support ve...

This study analyzes the advantages of Support Vector Regression (SVR) in the prediction of energy demand, decides the set of input vectors and output vectors and then establishes the model of prediction of Energy demand by SVR based on Matlab technology Modeling and Simulation of Energy demand from 1985 to 2009. At last, we apply this method to pre...

According to the specific requirements of time domain airborne electromagnetic method detection system, a whole bridge high-power switching power supply is designed based on limited double pole control. Combined with the designed whole bridge topologies, its working process is discussed and the realization process of soft switch is analyzed. Throug...

The borehole-surface networked oil-water interface resistivity imager receiver which is in-depth research and designed in the thesis bases on the borehole-surface resestivity method.The text recommended a few hardware and the software constitution of module. The main function of every module is set forth in detail.These include the kind of system e...
