[5] Due to the extensive coal industry in the region, Jincheng has gained notoriety for air pollution.

Efforts have been made to enhance the air quality in the city, such as tree planting, developing and maintaining vast parks and ecological reserves, shutting down or relocating some of the most polluting factories, and promoting the use of coalbed methane, which is a cleaner fuel source than coal.

The famous battle of Changping between Qin and Zhao took place in Gaoping City of Jincheng towards the end of the Warring States period.

It was not until the Republic of China period that Yuan Shikai issued a policy to transform all Chinese states into counties.

Coal-beds cover more than 56% of the total area, predominantly comprising anthracite, a high-quality coal with minimal impurities.

In addition, Jincheng has a substantial coal mine methane field, discovered in Qinshui county in 2001.

Apart from its coal-related industries, Jincheng also houses a significant Foxconn manufacturing campus that produces fiber optic parts, with an annual output value of over 3 billion RMB.
