Does anyone know the distribution of Qingdao electronics factory? Which area is more?

There are mainly Huangdao Development Zone and Chengyang District: there is Danshan Industrial Park, and most of the electronics factories in this industrial park are foreign; There are also many airport industrial parks and export processing zones in Hetao, most of which are foreign capital. If it is guaranteed to choose foreign capital for operation or trade, it is more appropriate to choose Qingdao local agent factory or joint-stock factory for operation.
