Agglomeration effect is a common economic phenomenon, such as industrial agglomeration effect. The most typical example is Silicon Valley in the United States, where dozens of global IT giants and countless small and medium-sized high-tech companies gather. Domestic examples are not uncommon. In Zhejiang, industries such as small household appliances, shoemaking, garment making, button making and lighters are all clustered in specific areas, forming a regional centralized manufacturing layout. Similar effects also appear in other fields. Big cities like Beijing and Shanghai have various agglomeration effects, including economy, culture, talents, transportation and even politics. There is also agglomeration effect in knowledge management, and through this effect, we can control the spread and enjoyment of knowledge in the organization to some extent. The gathering of catering enterprises can form industrialization, control the spread and enjoyment of knowledge to a certain extent, and improve competitiveness and popularity. They can also influence each other and depend on each other.
