Why is Li Andong U Valley Suzhou Xukou Science and Technology Zhihui Industrial Park so biased?

Prevent urban environmental pollution. Because the urban land price is very expensive and the suburban land price is very cheap, for production enterprises, they can only choose the cheap land in the suburbs to build large-scale factories, and at the same time avoid the city center to prevent urban environmental pollution, so Li Andong U Valley Suzhou Xukou Science and Technology Zhihui Industrial Park is located in a remote place.
