So one of the things I've been doing over the last few years is really compiling data on things that could either happen within national borders or across national borders, and I've looked at the cross-border component as a percentage of the total.
我在过去几年所做的 实际上是收集那些相关数据， 既有国内的也有国际的， 再计算那些跨越国界的部分 占总量的百分比。
