不稳定性

But network economy has the characteristic that is different from hypostatic economy, wait like sex of high fluidity, instability, high risk and tall speculation, its characteristic considers on superintendency means, for example the principle of an essential sex of policy of the taxation on the tradition is apanage principle, but in Internet in fictitious world, individual income tax is asked for by who with respect to existence problem.

但网络经济具有不同于实体经济的特点，如高度流动性、不稳定性、高风险性和高投机性等，在监管方式上考虑到其特殊性，例如传统上税收政策的一个根本性原则就是属地原则，但在互联网虚拟世界中，个人所得税由谁来征就存在问题。
