北部新区 is a common naming pattern for urban expansion zones on a city's north side. Chongqing's
两江新区 — which absorbed the older
重庆北部新区 in 2010 — is the best-known example, but many cities (
南宁,
海口,
天津, etc.) have their own
北部新区. These zones typically host government relocation, tech parks, and new housing.
