Small and micro enterprises are collectively referred to as small enterprises, micro enterprises, family workshop enterprises and individual industrial and commercial households, which was put forward by Professor Lang Xianping, the chief economist in China.

The significance of the state's strong support for small and micro enterprises-

If state-owned enterprises and large enterprises in various forms are the main force of China's market economy, then small and micro enterprises are guerrillas and light cavalry that play an important role in China's market economy. They can go into battle lightly and advance and retreat quickly;

If all localities can support the development of small and micro enterprises, it will affect the distribution of China's labor force and gradually change from intensive to decentralized, restricting a large number of labor force from turning to large and medium-sized cities since the reform and opening up;

It is conducive to slimming cities, accelerating urban and rural economic development and narrowing regional differences. The chain reaction caused by this will also be varied. For example, local employment can fundamentally solve serious social problems such as left-behind children and left-behind elderly people, as well as corresponding education problems.
