摘要
为探寻我国股指期货市场与股指现货市场间的价格发现能力,本文利用一分钟高频数据进行了实证分析。研究结果表明:股指期货价格和股指现货价格之间存在协整关系和双向价格引导关系,股指期货对股指现货的引导力度相对较大、股指期货领先股指现货7分钟,而股指现货领先股指期货2分钟;从冲击反应来看,股指期货对股指现货的冲击速度较快且持久,股指现货对股指期货的冲击相对比较迟缓且短暂;从价格发现程度来看,股指期货市场具有较强的价格发现能力,在信息传递中居于主导地位,是价格发现过程的主要驱动力量。
To examine the price discovery ability between the stock index futures market and the stock index spot market in China, the every minute's high frequency data of Hushen 300 index futures and the Hushen 300 index are investigated empirically. The results show that there are both cointegration relationship and the bi - directional price lead relationships. The lead from stock index futures to stock index is comparatively stronger. In the impulse reflection aspect, the response speed of the stock index to the stock index futures is quicker and the response times is permanent. Moreover, the price discovery ability of the stock index futures is stronger, and the stock index futures market has a dominant status in information transmission and is a mainly driving force in price discovery process.
