The great leap of Shanghai's economy benefited from the amazingly fast development of industry. In the past the city gave priority to advanced manufacturing industries and promoted the construction of its industrial base and large projects. The manufacture of automobiles, electronic and communication equipment, petrochemicals, steel products, equipment assemblies and biomedicine had once been promoted as the six pillar-industries of Shanghai.
Shanghai still pays much attention to its industry. There are many industrial areas here such as Jinqiao Export Processing Zone in Pudong New Area, Zhangjiang Hi-Tech Park and some other processing zones in Jiading, Qingpu, Songjiang and Minhang Districts. As a result the city's industrial production continues to grow rapidly. There is no doubt that industry makes a lot of economic profit; however, it is much more costly to the environment.
The architectural industry has also developed quickly in the area. The construction of airports, railways, highways, expressways, subways, maglev lines, ports, bridges and tunnels forms a convenient transportation network. Various commercial buildings, residential buildings and other infrastructure in the city create an open and pleasant environment for investment and further development.
Other booming industries, especially the service industries, contribute a lot to the city's economy. In recent years the financial market system has gradually matured, providing citizens and tourists with improved services. Domestic and international trade also has developed quickly. The Lujiazui Finance and Trade Zone in Pudong is now becoming more and more influential. It brings together many financial and commercial institutions such as stock exchanges, securities companies and insurance companies, both Chinese and foreign.
Transportation, especially the metro system in this city, is developing vigorously, providing sufficient transport capability and good services. The prosperous postal services, communications and information industries facilitate daily communication among people.
Various other service industries are booming here, so that the living standards of its citizens are improved. These include catering, hotel, entertainment, tourism, real estate, education, culture, health, physical training, TV and broadcast, consultation and information services, technology services, public utilities and social welfare.
