As one of the largest non-ferrous metals futures trading markets, Chinese non-ferrous metals futures market plays an important part in the world. However, research based on Chinese futures market of the price-volume relation is rather sparse. This paper studies the relation between returns volatility and trading activity of copper and aluminum futures in Chinese non-ferrous metals futures market on the basis of mixture distribution hypothesis. In addition, we divide the daily volatility of futures market into overnight volatility and trading volatility to distinguish between international market and local market. To discriminate between the impact of the market trends and of innovation on returns volatility, we also divide trading activity into expected and unexpected part on the basis of Gallant et al. and Bessembinder et al. The results show that the returns volatility increases when the trading is frequent, whereas it decreases when open interest increases. Furthermore, the trading activity and international market have a greater influence on aluminum futures than on copper futures.
中国有色金属期货市场是世界上最大的有色金属期货交易市场之一，在世界有色金属期货市场中占有重要地位。然而，基于中国期货市场的价量关系研究却相当稀少。本文在混合分布假设的基础上，研究了中国有色金属期货市场铜铝期货的收益波动与交易活跃度的关系。此外，我们将期货市场的每日波动率分为隔夜波动率和交易波动率，以区分国际市场和本地市场。为了区分市场趋势和创新对收益波动的影响，我们还在Gallant et al.和Bessembinder et al.的基础上将交易活动分为预期部分和非预期部分。结果表明，当交易频繁时，收益率波动率增大，而当持仓量增加时，收益率波动率减小。此外，交易活动和国际市场对铝期货的影响大于对铜期货的影响。
