Industry is 72.8% of China’s gross domestic product (GDP) in 2005. Industry (including mining, manufacturing, construction, and power) contributed 46.8 percent of GDP in 2010 and occupied 27 percent of the workforce in 2007. As of 2015, the manufacturing industrial sectors contribute 40% of China's GDP. The manufacturing sector produced 44.1 percent of GDP in 2004 and accounted for 11.3 percent of total employment in 2006. China is the world’s leading manufacturer of chemical fertilizers, cement, and steel. Prior to 1978, most output was produced by state-owned enterprises. As a result of the economic reforms that followed, there was a significant increase in production by enterprises sponsored by local governments, especially townships and villages, and, increasingly, by private entrepreneurs and foreign investors, but by 1990 the state sector accounted for about 70 percent of output. By 2002 the share in gross industrial output by state-owned and state-holding industries had decreased with the state-run enterprises themselves accounting for 46 percent of China’s industrial output. In November, 2012 the State Council of the People's Republic of China mandated a "social risk assessment" for all major industrial projects. This requirement followed mass public protests in some locations for planned projects or expansions.
Industry and construction account for about 48% of China's GDP. China ranks second worldwide in industrial output. Major industries include mining and more processing; iron and steel; aluminum; coal; machinery; armaments; textiles and apparel; petroleum; cement; chemical; fertilizers; food processing; automobiles and other transportation equipment including rail cars and locomotives, ships, and aircraft; consumer products including footwear, toys, and electronics; telecommunications and information technology. China has become a preferred destination for the relocation of global manufacturing facilities. Its strength as an export platform has contributed to incomes and employment in China. The state-owned sector still accounts for about 40% of GDP. In recent years, authorities have been giving greater attention to the management of state assets — both in the financial market as well as among state-owned-enterprises — and progress has been noteworthy.
