Heavy, light and distribution industries

Even before and during the Second Sino-Japanese War, the shipbuilding and locomotives industries were located in the city such as the companies which later became Dalian Shipbuilding Industry Company and Dalian Locomotive & Rolling Stock Works (DLoco). After the WWII, Dalian became an important center of the heavy and light industries, including companies such as Dalian Heavy Industry Co., Dalian Chemical Group, and Wafangdian Bearing Co.; and of the distribution industry, such as the Dashang Group.

Dalian Port is an important port for international trade. It has established trading and shipping links with more than 300 ports in 160 countries and regions of the world. There are over 100 international and domestic container shipping routes. A harbor for oil tankers (the largest by tonnage in China), at the terminus of an oil pipeline from the Daqing oilfields, was completed in 1976. Dalian is the 6th largest port in China; and according to AAPA world port ranking data, Dalian is the 8th busiest port in the world by cargo tonnage in 2012, and the 12th busiest container port in the world by total number of TEUs handled in 2013. Accordingly, Dalian is a major center for oil refineries, diesel engineering, and chemical production.

Also completed in 1993 is a newer port called Dayaowan Port (Chinese: 大窑湾港; pinyin: Dàyáowān Gǎng), on Dagushan (大孤山; Dàgūshān) Peninsula in the northern suburbs, specializing in import-export of mining and oil products. Together with the Dalian Railway Station, Dalian North Railway Station, Dalian International Airport and two major express roads to Shenyang (Shenda Expressway), Changchun (Changda Expressway), Harbin (Hada Expressway) in the north and to Dandong to the east, Dalian has been an important distribution center.
