Jiangsu
In 484 BC, the state of Wu defeated Qi, a major power in modern-day Shandong province. This victory marked Wu as a great power under King Helu of Wu. The state of Wu was subjugated by Yue in 473 BC. Yue itself fell to Chu in 333 BC. Qin unified China in 221 BC. During the Han dynasty, which lasted from 206 BC to 220 AD, Jiangsu was administered under two zhou: Xu Province and Yang Province. Southern Jiangsu became the base of Eastern Wu between 222 and 280. Its capital, Jianye, is now Nanjing. When nomadic invasions overran northern China in the 4th century, the Jin dynasty court moved to Jiankang. Cities in southern and central Jiangsu swelled with migrants from the north. Jiankang remained the capital for four successive Southern dynasties. It became the largest commercial and cultural center in China. After the Sui dynasty united the country in 581, the political center shifted back north. The Grand Canal was built through Jiangsu to link the Central Plains with the prosperous Yangtze Delta. The Tang dynasty relied on southern Jiangsu for annual grain deliveries. During the Song dynasty, which spanned 960 to 1279, Jiangnan emerged as a trade center. Major cities like Suzhou or Yangzhou became synonymous with opulence and luxury. In 1127, the Jurchen Jin dynasty gained control of North China. The Huai River served as the border between Jin and Southern Song. The Mongols took control of China in the thirteenth century. The Ming dynasty established its capital in Nanjing in 1368. Regions surrounding Nanjing were designated as Nanzhili province. A coup by Zhu Di moved the capital to Beijing. Nanjing kept its status as the southern capital. In late Ming, Jiangnan continued to be an important trade center. Some historians see incipient industrialization in the textiles industry at that time. The Qing dynasty converted Nanzhili to Jiangnan province. In 1666, Jiangsu and Anhui split apart as separate provinces. Jiangsu's borders have been stable since then.
Jiangsu has the second-highest GDP among Chinese provinces after Guangdong. Its 2022 nominal GDP reached CN¥137,300 per capita, becoming the first province in China to reach the $20,000 mark. In 2022, the total GDP was more than 12.29 trillion US dollars. If it were a country, it would rank twelfth-largest globally. Jiangsu hosts over 100 economic and technological development zones. It is home to many of the world's leading exporters of electronic equipment, chemicals, and textiles. Since 2006, it has been China's largest recipient of foreign direct investment. Cities like Suzhou and Wuxi outstrip the provincial capital, Nanjing, in total output. In the eastern outskirts of Suzhou, Singapore built the Suzhou Industrial Park. This park is the only industrial park in China entirely funded by a single foreign country. The province developed heavy industries such as chemical industry and construction materials since 1949. Important industries include machinery, electronics, chemicals, and automobiles. The government promoted the solar industry, hoping it would be worth 100 billion RMB by 2012. Jiangsu contains coal, petroleum, and natural gas deposits. Xuzhou serves as a coal hub of China. Salt mines in Huaiyin hold more than 0.4 trillion tonnes of deposits. The province has an extensive irrigation system supporting agriculture based on rice and wheat. Main cash crops include cotton, soybeans, peanuts, rapeseed, sesame, ambary hemp, and tea. Silkworms form an important part of agriculture, with Lake Tai region being a major silk production base. Jiangsu produces freshwater fish and other aquatic products.
Jiangsu is flat, with plains covering 68 percent of its total area. Water covers another 18 percent. Most of the province stands not more than 50 meters above sea level. Mount Huaguo near Lianyungang is the highest point at 625 meters. Before 1194 AD, the Huai River cut through north Jiangsu to reach the Yellow Sea. Since 1194 AD, the Yellow River changed course several times, running into the Huai River instead of Bohai Bay. The silting caused by the Yellow River was so heavy that after 1855, the Huai River ended in flooding. It pooled up, forming and enlarging Lake Hongze and Lake Gaoyou. The annual average rainfall falls mostly during summer monsoons. Extreme weather has become stronger and more common. According to data from 1961 to 2007, the province experiences temperature increases between 0.16 and 0.45 Celsius per decade. Total precipitation changes range from -28.7 to 37.09 mm per decade. Jiangsu's agriculture, ecosystem, water resources, transportation, and coastline are all negatively impacted. The speed of sea level rise exceeds the world's average by a large margin. A ranking released in early 2023 by the Cross Dependency Initiative puts Jiangsu as the most vulnerable region globally. The fourteenth five-year plan, endorsed in 2021, indicates steps toward a low-carbon transition. The provincial government aims for an 18% carbon dioxide decrease per unit GDP. Plans include recovering damaged coastal regions like Lianyungang and Yancheng. Seawalls and river floodgates will improve resilience against rising sea levels.
As of 2022, Jiangsu hosts 168 institutions of higher education, ranking first among Chinese provinces. There are two Project 985 universities, eleven Project 211 universities, and sixteen Double First-Class Construction universities in the province. A combination of 93 members of the Chinese Academy of Sciences and Chinese Academy of Engineering work in Jiangsu. As of 2025, six major cities rank among the world's top 200 cities for scientific research output according to the Nature Index. These cities include Nanjing at fifth place, Suzhou at thirty-third, Zhenjiang at ninety-eighth, Yangzhou at one-hundred-eighteenth, Wuxi at one-sixty-first, and Changzhou at one-seventy-third. Jiangsu is the only province in China with at least five major cities achieving this distinction. Nanjing University, Southeast University, Soochow University, and China Pharmaceutical University are among the notable institutions. The province has many highly ranked educational institutions. Sixteen universities are listed in the Double First-Class Construction program. This places Jiangsu second after Beijing. The high density of academic institutions supports a robust research environment. Students from across China compete for admission to these prestigious schools. The concentration of talent drives innovation in technology and science.
Kunqu originated in Kunshan as one of the most renowned forms of Chinese opera. Pingtan is a form of storytelling accompanied by music popular throughout the region. Types include Suzhou Pingtan, Yangzhou Pingtan, and Nanjing Pingtan. Wuxi opera is popular in Wuxi, while Huaiju thrives around Yancheng. Jiangsu cuisine ranks among the eight great traditions of Chinese food. Suzhou is well known for silk, embroidery, jasmine tea, stone bridges, pagodas, and classical gardens. Nearby Yixing is noted for teaware, while Yangzhou is famous for lacquerware and jadeware. Nanjing's yunjin is a noted type of woven silk. Since ancient times, south Jiangsu has been famed for prosperity and opulence. Inserting place names like Suzhou or Yangzhou into poetry gave an effect of dreaminess. Poets wrote: "Above there is heaven; below there are Suzhou and Hangzhou." This saying continues to be a source of pride. Similarly, poets dreamed of Yangzhou with a hundred thousand strings of coins wrapped around its waist. The province contains historic sites such as the Purple Mountain Observatory and Sun Yat-sen Mausoleum. Suzhou's classical gardens are designated as a UNESCO World Heritage Site. Hanshan Temple and Huqiu Tower stand nearby. Zhouzhuang is an international tourist destination with Venice-like waterways. Yangzhou is known for Slender West Lake. Wuxi is home to the world's tallest Buddha statue. Xuzhou is designated as one of China's eminent historical cities.
