Jinan is a sub-provincial city and the capital of Shandong Province in the People's Republic of China. The area of present-day Jinan has played an important role in the history of the region from the earliest beginnings of civilization and has evolved into a major national administrative, economic, and transportation hub. The city is located in north-western Shandong about 400 kilometres (250 mi) south of the national capital of Beijing, it borders Liaocheng to the southwest, Dezhou to the northwest, Binzhou to the northeast, Zibo to the east, Laiwu to the southeast, and Tai'an to the south.

Jinan is located in the north-western part of Shandong province at 36° 40′ northern latitude and 116° 57′ east of Greenwich. In the relief of the region, the city occupies a transition zone between the northern foothills of the Taishan Massif to the south of the city and the valley of the Yellow River to the north. Karst aquifers in limestone formations sloping down from the south to the north give rise to many artesian springs in the city area. Because Jinan's geographical location falls within the warm temperate continental monsoon climate zone, Jinan has four distinct seasons. The city is dry and rainless in spring, hot and rainy in summer, crisp in autumn and dry and cold in winter. The average annual temperature is 14.2°C, and the annual rainfall is around 675 mm. January is the coldest and driest month, the monthly averages are -5.4°C for the daily minimum temperature, 3.6°C for the daily maximum temperature, and 6.6 mm for the rainfall. July is the warmest and wettest month, the corresponding numbers are 23.5°C, 32.6°C, and 190.9 mm (Source: The Global Historical Climatology Network, version 2 beta, covering 874 months between 1916 and 1990). Temperature Inversions are common occurrences (about 200 days per year).

Jinan's 2005 estimated population is 5.69 million in the whole city-jurisdiction area, with a total of 2.54 million living in urban areas. The population is predominantly Han (98.3%), with very small portions of Hui and Manchu Chinese. Jinan has a significant Muslim community centred in the city's Muslim quarter, located to the west of the historical center.

Local residents in the city proper, as well as in the surrounding areas, have traditionally spoken the Jinan dialect of Mandarin that is not readily understood even by native speakers of standard Mandarin. The younger people of Jinan are more likely to speak standard Mandarin, whereas many older residents retain strong local dialect elements in their speech. Nevertheless, even the younger residents of Jinan tend to retain a strong local accent and mix local vocabulary into the standardized Mandarin vocabulary.

Jinan has its own cuisine, the Jinan style of the Lu cuisine, one the Eight Culinary Traditions of China.

With the shift of the Yellow River to a new bed right to the north of Jinan (in 1852) and the establishment of a railroad hub, the city became a major market for agricultural products from the productive farming regions to the north. Following the trade in agricultural goods, the city developed a textile and clothing industry, flour mills, oil presses, as well as factories producing paper, cement, and matches. In the 1950s, large iron and steel works as well as chemical factories were established around Jinan. The large metal works produce pig iron, ingot steel, as well as finished steel. In the 1970s, factories for the production of trucks and construction vehicles were added.

Jinan has a pool of high-quality labor resources. There are 18 universities and colleges in the city where more than 200,000 students are studying. Among the 200+ research institutes in the city, 10 are national laboratories.

The focus on technology intensive industries has transformed Jinan from a city supported by heavy industry and textiles to a city with more diverse industrial structure. Information Technology, transportation tools, home appliances, bio-engineered products, etc. have become important components of the area's industry. Jinan's IT-related economic output was ranked to be in the fourth place nationally in 2004.
