The digital economy era is a new form of economic and social development after the agricultural economy and industrial economy, and this new model based on bit thinking is different from the state of the Internet era in which bits and atoms are separated, and the digital economy needs to put bits and atoms together and think about their interrelationship.

The digital economy is a stage of the concept, between the Internet economy and the future of the intelligent economy of an intermediate stage, the bit will become like water and electricity as the ecological elements to penetrate all walks of life, penetrate every link of the economy and society, it will continue to release the impact on the economy and the promotion of the role of the economy to a certain stage, there will not be a reference to the digital economy. Like now every business is using electricity, but no business will say they are a business that uses electricity.

The core factor of production in the era of agricultural economy is land; the core factor of production in the era of industrial economy is technology and capital; the core factor of production in the digital economy is bits, that is, data;

No obvious boundary exists between production and consumption in the era of digital economy, and the consumer is able to y participate in the process of production; and the producer is able to track to every stage of consumption. Under these conditions, digital literacy has become the most basic survival skills that the supply side and the consumption side should have, digital literacy includes digital skills and professional skills, workers need to have dual skills, the current market is generally short of talents with high digital literacy.

From the Internet to information-physical systems to information-physical biosystems, digitalization is gradually evolving in depth, with more emphasis on human-computer interaction, and the boundaries between the virtual and physical worlds will gradually disappear.

We can't deny the existence of the digital economy, nor can we impede its progress. Internet + emphasizes connectivity, and the digital economy is the result of the benefits generated by comprehensive connectivity. We are entering the bit world, the laws of this world are completely different compared to the atomic world, we need to establish a completely new mode of thinking. So before the next era comes, stockpiling knowledge of the digital economy can help us realize the crossing.
