摘要
以2007年5月30日印花税上调事件为研究对象,采用2007年上证综指和深成指日收益率数据,借鉴EGARCH模型进行建模.研究发现,从长期看,印花税自0.1%上调至0.3%后对市场波动性和交易量没有显著影响,反映出印花税是否调整或调整的幅度并非投资者改变投资策略的主要考虑因素.印花税作为调控市场的手段其作用是有限的.
Taking the event that China increased the transaction cost of stock market on May 30th, 2007 as an object, a model based on EGARCH is established in this paper, adopting the SSE Composite Index and SSE Component Index daily return data. It is found through this modeling that the increase of transaction cost from 0. 1% to 0. 3 % has no significant effect on the volatility or volume of the two markets, indicating that transaction cost is not the major factor to affect the traders＇strategies. As a macro - control method, the adjustment of transaction cost has only a limited effect.
