---
Key subsidiaries of the Hyundai Group, HD Hyundai Heavy Industries and HD Hyundai Mipo Dockyard, are located in Dong District.
However, since the mid-2010s, the shipbuilding industry has faced a severe downturn, leading to the spin-off of some divisions of Hyundai Heavy Industries and the relocation of certain facilities to other regions. This has resulted in a population decline and a slight drop in average income. Nevertheless, the area still ranks within the top 20 nationwide in terms of economic standing. Starting in the 2020s, the recovery of the shipbuilding industry has shown signs of revival, with rising real estate prices signaling a potential rebound.
