摘要: 沪深300股指期货与现货波动溢出问题的研究对于风险管理具有重要的理论和现实意义。本文旨在基于高频数据,利用异质金融市场驱动的HAR-CAW模型研究我国股指期货和现货市场之间及其自身的短期、中期和长期波动溢出问题。研究结果表明,沪深300股指期货与现货市场之间整体上存在着双向波动溢出效应,但是溢出效应不对称,期货对现货的溢出效应占主导地位;在相互间各期溢出研究上,两市场间的各期溢出表现各不相同;在自身溢出效应上,各期整体而言现货市场存在溢出,而期货市场不存在。

Abstract: Volatility spillover effects between Shanghai and Shenzhen 300 index futures and spot market is of great significance for investors of risk management. This article is based on high frequency data, using heterogeneous financial market driven HAR-CAW model to study short-term, medium-term and long-term volatility spillovers between future market and spot market and of their own. The results show that there are two-way volatility spillover effects, but the effects are not asymmetric: the futures market dominates the volatility spillovers. On the study of two-way volatility spillover effects, the two markets have different performances during short-term, medium-term and long-term; on the study of its own spillover effects, overall speaking, volatility spillovers exist in each phase of the spot market, but not in the futures market.

Key words: volatility spillovers, index futures, high-frequency data, HAR-CAW model
