Considering that memory and conformity could affect the agent’s decision, in this paper, we propose a novel model to describe the vaccination dilemma by entangling the spreading dynamics with an evolutionary framework. Our results indicate that if the individuals make decision mostly depending...

With an increase in China's oil imports, China's oil supply will also continue to be effected by the socio-economic stability of oil-exporting countries and the safety of oil transport routes. This paper introduces a systematic and quantitative method to evaluate the influence of China's oil...

A universal bipartite model is proposed based on an energy supply–demand network. The analytical expression of SPL distribution of the node weight, the “shifting coefficient” α and the scaling exponent γ are presented without edge weight growth by using the mean-field theory approach....

Purpose: This paper aims to study the oscillation phenomenon before chaos as well as its mechanism of occurrence in the energy-saving and emission-reduction system. Design/methodology/approach: The system dynamics analysis, phase portrait analyses, equilibrium point analysis and bifurcation...

Based on the status quo of carbon emissions in China, this paper introduces dynamic evolutionary factors, advance rate, critical time and evolutionary coefficients of carbon emissions, deducing relative theories, such as Change Trends Theorem and Evolutionary Theorem. Least-square method is used...

Carbon price prediction is a key issue in the field of carbon market research. However, the existing methods of carbon price forecasting mostly regard carbon price series as a certain time series, but pay less attention to the uncertainty implied by carbon price series. Based on this, this paper...
