我国股票市场对冲通货膨胀风险能力的时间区问效应研究

摘要

Setting the Chinese stock market as the example and using A-share index of Shanghai stock exchange and Shenzher stock exchange, the paper studies the time section effect of the stock market sterilizing inflation risk. On the basis of other research or models, combining with the panel data model, the paper carefully studies the time section effect of the capacity of the stock markel sterilizing inflation risk, and reveals the relationship between the period of holding stocks and the capacity of sterilizing inflation risk The paper concludes that the longer period of holding stQcks （30 and over 30 months） does not necessarily lead to the improvement of effect of sterilizing inflation. Comparing to short-term operation, the period of 12 to 24 months of holding stocks can save transactior cost and avoid inflation risk.%本文以我国股票市场为例，使用了上证A股和深证A股指数数据，对股票市场对冲通货膨胀风险的时间区间效应进行了研究。通过对前人研究模型的拓展，结合面板数据模型，细致地研究了我国股票市场对冲通货膨胀的时间区间效应，并得出了股票持有期与对冲通货膨胀能力的关系。本文的结论是：我国股票市场上较长持有期限（30个月及以上）不一定会导致对冲通货膨胀效果的改进；相对于短线操作来说，12到24个月之间的持有期长度可以在节约交易成本的情况下规避通货膨胀风险。
