同学你好，可以简单理解为，作为投资人，从账户里拿钱，或者往账户里放钱，这种算作现金流，如果是账户balance余额的变化，就不算是现金流。这道题是0时刻往账户里放了10million，1时刻又往里放了100million，这种就是现金流，而账户余额在t=1时刻变成了10×1.14，这不是现金流。期末的时候投资结束，投资人可以拿到的钱是10×1.14×1.08+100×1.08，这个也算现金流。
PZ2017092702000028 这道题，买股票算是投资者往账户里投钱，dividend是从账户里往出拿钱，拿出来的钱不会再参与下一期的收益，所以净投入就是往里投的钱减去从里面拿出来的钱，这个是cash flow。
我们也可以这么想，这道题可以想象成t=1时刻，投资人把第一期挣到的利息1.4million取出来了，这样也可以算成是现金流，但是投资人取出来之后看了一眼，又放回去了，而且还又增加了100million的投资，相当于整个过程是：现金流+1.4，现金流-1.4-100，净投入还是100million。而PZ2017092702000028 这道题，投资者拿到dividend，不会再往账户里投了，而是揣自己口袋里了，对于投资者来说，dividend就是实实在在的现金流流入。
