The price of crude oil is fluctuating. Researchers focus on the fluctuation of crude oil prices or relationship between crude oil futures and spot prices. However, the relationship also presents fluctuation which draws our attention. This paper designed a complex network approach for examining...

This study introduces an approach to study the multiscale transmission characteristics of the correlation modes between bivariate time series. The correlation between the bivariate time series fluctuates over time. The transmission among the correlation modes exhibits a multiscale phenomenon,...

For a country that imports crude oil, the forex burden is always fluctuant due to the fluctuation of international crude oil prices and exchange rates over time. The gap discovered between international crude oil prices and the crude oil price based on exchange rates may indicate the fluctuation...

International oil trade is a subset of global trade and there exist oil trade communities. These communities evolve over time and provide clues of international oil trade patterns. A better understanding of the international oil trade patterns is necessary for governments in policy making. To...

Traditional international trade theories have some limits in analyzing international crude oil trade as a system with numerous countries and complicated relationships. Complex network theory provides a method to analyze the world-wide trade system entirely and partly. Complex network models on...

Shareholders are the owners of listed companies, and their relationships can directly affect the structure of the stock market. In this paper, we analyze the topological properties and evolution of the cross-shareholding networks of listed companies in the past 5 years in China from 2007 to...

In the present article, natural resource production in China during 2000–2011 was investigated on the basis of exergy as a unified indicator to demonstrate the structural and regional variation of this country's resource supply. Using exergy, different types of resources may be added and...

Two-mode and multi-mode networks represent new directions of simulating a complex network that can simulate the relationships among the entities more precisely. In this paper, we constructed two different levels of networks: one is the two-mode primitive networks of the energy listed companies...
