Haimen (simplified Chinese:海门;traditional Chinese:海門;pinyin:Hǎimén;lit. 'sea gate',Qihai dialect:[haɪ.məŋ],Shanghai:[hɛ̝.məŋ]) is a district ofNantong,Jiangsu province. Located on the northern bank of theYangtze River estuary, it facesShanghai across the river. Renowned as the "Gateway to the Yangtze River and the Yellow Sea" and "Little-Pudong", the district covers about 1,149 square kilometers and had a permanent population nearly 1 million in 2025.[6] With its coastline along theYangtze and theYellow Sea, Haimen has historically been famous for fishing and salt production, and in modern times has developed into an important port-based industrial hub.
The area that is now Haimen was formed fromsilt deposits from theYangtze River. Severalsandbanks, including Dongzhou (东洲;東洲) and Buzhou (布洲), joined with the mainland in theTang dynasty. In 958 CE, during theLater Zhou dynasty in theFive Dynasties and Ten Kingdoms period, Haimen County was established with the county seat at Dongzhou Town.[7] At this time, Haimen andJinghai District (静海) were merged into the newly formedTongzhou District (通州).[8]
Because the mouth of the Yangtze River moved northward during theMing dynasty, Haimen has dealt with flooding that destroyed parts of the county, including Lüsi (吕四;呂四), Yudong (余东;余東), and Sijia (Chinese:四甲).[7]
In 1672, under theKangxi Emperor of theQing dynasty, the seat moved toJinghai Township (静海乡;靜海鄉). Starting from 1701, the river's course moved south, creating more than 40 new sandbanks. In 1768, the county became an independent subprefecture with the seat moving to Maojia Town (茅家镇;茅家鎮).[7]
In the late Qing period, the industrialistZhang Jian was born in Changle Town, Haimen. In 1895, he founded the Dasheng Cotton Mill, which spurred the rise of China’s modern textile industry and helped make Haimen and Nantong major centers of commerce and industry.[9]
In 1912, one year after theRepublic of China was founded, Haimen once again became acounty. However, in 1949, when thePeople's Republic of China was founded, Haimen became governed underNantong Prefecture. Once county-level governments started to reappear in 1983, Haimen was reinstated as a county, and in June 1994, Haimen became acounty-level city.[7]
In 2020, Haimen became a district of Nantong.[10]
Haimen District is one of the economically strong districts along the Yangtze River in Jiangsu Province. In 2023, the regional GDP reached 16.9 billion RMB, representing a 6% increase. General public budget revenue was 750 million RMB, actual foreign investment reached USD 360 million, construction output was 22.33 billion RMB, and total imports and exports reached 32.24 billion RMB, of which cross-border e-commerce accounted for 6.37 billion RMB. In 2024, the official plan projected GDP of 17.72 billion RMB, a 6.5% growth, with the per capita disposable income of urban residents expected to reach 67,400 RMB.[6]
Haimen has long been noted for textiles, garments, and the construction industry, and holds titles such as "Hometown of Elevators in China" and "Hometown of Construction."[9]In recent years, the local government has promoted high-end equipment and emerging industries, including ship and marine engineering equipment, auto parts, new materials, and health food. In the provincial-level Haimen Auto Parts Industrial Park, 71 enterprises above designated size achieved industrial output of more than 16 billion RMB (approximately USD 2.23 billion) in 2024, with a cluster of 121 key firms. Local companies emphasize independent research and technological upgrading: for example, Jinyicheng (Nantong) Precision Technology Co. developed brake components adopted by international manufacturers, with monthly production up to 400,000 units. Another company, Nantong Presstler Auto Parts, built proprietary hot-forming production lines that improved strength and corrosion resistance while reducing costs.
Haimen has long been celebrated as the "hometown of education." Notable figures include industrialist Zhang Jian, who was born in Haimen and not only advanced modern textile industry but also founded institutions such as Nantong Normal School and Nantong Museum. Education remains a local priority, with primary and secondary schools ranking among the top in Jiangsu Province. Recent cultural activities include the "Tonglü Shanghai-style Culture Festival" and commemorations of Dong Zhujun, highlighting local history and Shanghai-influenced culture. In 2023, over 100 experts in local chronicles gathered in Haimen for the 170th anniversary of Zhang Jian's birth, discussing his contributions to historiography and industrial development.[9]
