Energy Financial Risk Management in China Using Complex Network Analysis

Abstract

Effective energy financial risk management is crucial to ensure that China's economic system can remain stable. This article utilizes the quantile vector autoregressive spillover index model, complex networks, and deep learning methods to simultaneously assess both the internal and external energy financial market risks in China. Spillover effects under different market conditions are also examined. The research findings indicate that: (1) Under extreme market conditions, static total spillover values between internal and external markets exceed 70%, while under normal market conditions, they are only around 53% and 13%, respectively; (2) Crude oil and fuel oil as well as energy and stocks are important nodes in both internal and external markets; and (3) The attention-convolutional neural network-long short-term memory model outperforms the second-best performing model, and achieves an improvement of 12.9% and 21.4% in terms of mean absolute error and root mean square error, respectively; inclusion of early warning indicators leads to further improvements of 19.8% and 31.9%, respectively.

Analyzing the Underlying Relationship Between Monetary Policy and Residential Property Prices in China

“…In many economically advanced regions, the escalating housing expenses have surpassed the ability of a significant portion of the population to sustain themselves, resulting in a demographic expansion commonly referred to as "mortgage slaves". The impact of housing price escalation on individuals is dual, encompassing both economic considerations and the fundamental need for existence (Fang et al, 2023;Wen & He, 2015).…”

The Dynamic Connectedness Between Environmental Attention and Green Cryptocurrency

“…Hence, the subsequent justifications underlie the necessity of undertaking this research endeavor. Initially, it can be argued that cryptocurrencies are considered currencies with negative environmental implications, making them unappealing to individuals who prioritize sustainable energy and environmental preservation as viable investment opportunities Fang et al, 2023;Symitsi & Chalvatzis, 2019).…”
