As a representative region with poor energy resource endowment in China, the Yangtze River Delta (YRD) poses pressing and vital issue for research on security. This study offers comprehensive assessment of security levels (ESL) YRD China from 2000 to 2019, emphasizing pivotal role electricity indicators transition using combination optimization model entropy method CRITIC method. Subsequently, we employed coupling synergy degree further quantify among different provinces verify effects...

Energy supply security is a significant part of China’s security, directly influencing national and economic social sustainability. To ensure both present the future energy supply, it essential to evaluate forecast level. However, forecasting level difficult because dynamic, many factors affect there lack accurate comprehensive data. Therefore, based on previous studies according characteristics development China, first, authors apply evaluation method quantify security. Second,...

Energy supply sustainability is an important issue in the field of energy security. To successfully achieve goals sustainable economic and social development to implement “Paris Agreement”, we need accurately evaluate predict countries or regions. However, it very difficult sustainability, because belongs a complex multi-attribute decision-making problem. This paper proffered new definition China put forward sixteen indicators for from four dimensions availability, environmental technical...

China's energy and chemical enterprises in the resource-based urban cities face challenges of climate change targets. Coal, Oil Gas Resources Comprehensive Utilization (COGRCU) project can address carbon hydrogen imbalance between conventional methanol from coal natural gas. Moreover, it improve conversion rates resource recovery. Therefore, is a better way for to transition sustainable development advocated by cities. In practice, actual benefits COGRCU are often different those expected...

In recent years, with the increasing impact of extreme weather events on energy security, vulnerability has increased significantly, and more international institutions departments have begun to incorporate resilience governance into security. This paper focuses China’s inter-provincial security assessment. Compared existing relevant research, significant features our work are (i) introducing concept presenting its evolution mechanism evaluation criteria, (ii) developing a gray relational...

Coal is a major source of energy in China. Quantifying China’s coal supply sustainability essential to track efforts towards sustainable development and achieve carbon neutrality goals. In this research, addition availability, economic sustainability, environmental technological we specially considered health security, transport supply. We select 19 indicators from the above six dimensions build index construct novel optimized comprehensive evaluation model with level difference maximization...

Using a dynamic model from 2005 to 2015, this study assessed China’s energy supply security in the provinces along “the Belt and Road”. Energy was conceptualized across four dimensions: availability, affordability, acceptability, technology efficiency. A used calculate weights for each indicator examine variation laws. It found that acceptability dimension had rapidly increased, indicating been widely accepted. Smooth were availability indicators, resources needed protect basic supplies...

A scientific assessment of the sensitivity Chinese coal market has become an important research topic. This paper combines Gaussian Process Regression (GPR) and Sobol analysis to construct a GPR–Sobol hybrid model innovatively applied market, thus addressing gap in economic applications this method. The is used analyze factors influencing prices China. effectively handles nonlinear relationships, enabling in-depth exploration key affecting price volatility quantifying their impacts,...

Coal mine ranks No.1 among the 6 major high-risk industries, so it is no doubt that senior managers in coal bear more stress than other industry executives. The massive working results serious influences on physical and mental health of mine, which might also induce safety risk mine. Therefore, to evaluate managers’ put forward strategies mitigating great theoretical practical significance improving reducing research has been made western countries for almost 50 years, China began mid late...

While specialized services continue to be developed in the mining industry, there has been a lack of corresponding risk management research China. This study develops assessment index framework general contract for mine production and operational service. From previous research, factors operation are identified is set up. An weight established using Delphi set‐valued statistics‐triangular fuzzy number method, comprehensive evaluation method applied assess risks. With Jinjie Coal Mine...
