Industries based on brainwork or knowledge are called the quaternary industry. 以腦力勞動(dòng)或知識為基礎的產(chǎn)業(yè)被稱(chēng)為第四產(chǎn)業(yè)。
The emergence and boom of the knowledge industry has led to the creation of the quaternary industry theory, which further divides intellectual work from physical labor. 知識產(chǎn)業(yè)的形成和繁榮直接導致第四產(chǎn)業(yè)理論的誕生，并且該產(chǎn)業(yè)區分開(kāi)了腦力勞動(dòng)和體力勞動(dòng)。
