摘　　要：基于余额宝2013Q2-2016Q1期间的季度时间序列数据,运用Granger因果检验、脉冲响应等计量方法,建立向量自回归(VAR)模型,实证检验了余额宝收益率与余额宝规模之间的关系。结果表明:余额宝收益率与余额宝规模存在正向变动关系,但是余额宝规模自身对它的发展以及余额宝收益率存在一定的抑制作用。Based on the quarterly time series data of Yu＇ebao during 2013Q2-2016Q1, by using Granger causality test, impulse response and other measurement methods, the vector autoregressive（VAR） model is established to carry out the empirical test of the relationship between the yield rate and fund size of Yu＇ebao. The results show that： there is a positive change in the yield rate and fund size of Yu＇ebao, but there is a certain inhibition in Yu＇ebao and its development and yield rate.
