余额宝对银行股影响的定量分析
首先通过互联网收集年对应的指标数据。然后利用SPSS软件对数据进行回归分析，经过模型的修正之后建立相应的线性回归模型，进而估计在余额宝不出现的情况下银行股的净利润，得到了余额宝对银行股有不利影响的结论。最后，通过数据分析余额宝对银行股的短期及长期影响，得出了余额宝对银行股影响的定量分析结果：(1)两者在短期内成负相关；(2)两者在长期内的相关性较小。

The quantitative assessment on the impact on bank stocks under the influence of Yu Ebao
Abstract: It is discussed in this paper that quantitative assessment on bank stocks under the influence of Yu Ebao. We all know that Yu Ebao is the first monetary fund on the Internet, and the capital quantity is beyond six billion yuan in one month. It shocks the entire financial world, and influences the banking industry in a certain extent. Hence, there must be a certain correlation between Yu Ebao and bank stocks. The relative model in this paper is based on the data of Yu Ebao and bank stocks between the year 2008 and year 2014. Then carry out relative research on short-term effects and long-term effects to reveal the quantitative assessment on the impact on bank stocks under the influence of Yu Ebao.
Firstly, gather the relative data from 2008 to 2014 through the Internet. Secondly, come to a conclusion that Yu Ebao hurts bank stocks through using SPSS software to carry regression analysis、revise models, and establish relative models to assess the net profit under the circumstances of Yu Ebao does not exist. Lastly, get the result of short-term effects and long-term effects through data analysis, and obtain the following two valid conclusions of the impact on bank stocks under the influence of Yu Ebao: (1) Correlation is negative in the short term; (2) Correlation is small in the long term.
