The sinking of three small enterprises is meaningless.

Promote rural economic development and optimize resource allocation.

1. Promoting rural economic development: By sinking the three small businesses into the countryside, it can effectively promote rural economic development, increase employment opportunities, improve farmers' income level, help narrow the gap between urban and rural areas, and promote coordinated economic and social development.

2. Optimize resource allocation: Rural resources are relatively abundant, especially labor resources. By sinking three small businesses, we can make better use of these resources and improve the utilization efficiency of resources. At the same time, it can alleviate the pressure of urban resources and alleviate the problems of urban land use and transportation.
