China's Manufacturing Hubs: Pearl River and Yangtze

By ChinaManufacturers.com Editorial Desk · Updated 30 October 2026 · How this page was researched

Where China's manufacturing is concentrated

China's two principal manufacturing regions are the Pearl River Delta in Guangdong province, now planned as part of the Guangdong–Hong Kong–Macao Greater Bay Area, and the Yangtze River Delta around Shanghai, which spans Jiangsu, Zhejiang and Anhui. Both were given formal development plans by the CPC Central Committee and the State Council in 2019, and those plans assign specific industrial and logistics roles to named cities.

This page describes each hub city only by what those official plans and official statistics state. Many other descriptions of Chinese cities ("the toy capital," "the lighting city") come from marketing material and are not repeated here. Where the Editorial Desk has no primary source for a city's specialty, the page says so.

An industrial cluster, in this sense, is a geographic concentration of manufacturers, component suppliers, toolmakers and logistics providers serving the same product families. Clustering is one of the main reasons China remains the default source for so many products, as the guide on why so much is made in China explains.

The Pearl River Delta and the Greater Bay Area

The governing document is the Outline Development Plan for the Guangdong–Hong Kong–Macao Greater Bay Area (《粤港澳大湾区发展规划纲要》), issued on 18 February 2019 and published on the central government's website. It covers nine Guangdong cities (珠三角九市) plus Hong Kong and Macao. The nine are Guangzhou, Shenzhen, Zhuhai, Foshan, Huizhou, Dongguan, Zhongshan, Jiangmen and Zhaoqing.

Shenzhen and Dongguan: the east-bank electronics cluster

The plan names Shenzhen and Dongguan as the core of a world-class advanced manufacturing cluster on the east bank of the Pearl River, with electronics and information technology as the named example: "以深圳、东莞为核心在珠江东岸打造具有全球影响力和竞争力的电子信息等世界级先进制造业产业集群." Shenzhen is cast as a special economic zone and "national innovation city." The plan also supports Dongguan in upgrading its traditional industries, which signals that the city's base extends beyond electronics.

Foshan and Zhuhai: the west-bank equipment belt

On the west bank, the plan makes Zhuhai and Foshan the lead cities of an advanced equipment manufacturing belt: "以珠海、佛山为龙头建设珠江西岸先进装备制造产业带." It also backs a pilot program for comprehensive manufacturing upgrading in Foshan.

Guangzhou: gateway, trade and transport

Guangzhou is designated a "national central city" and an "integrated gateway city," with international commerce and transport hub functions, and is paired with Foshan for urban integration. It hosts the China Import and Export Fair (Canton Fair); the Guangzhou municipal government reports that the 139th session (15 April to 5 May 2026) drew 314,000 overseas buyers, an organizer-reported figure. Guangzhou also shows how a single district can dominate a product category: in 2022, Baiyun District reported 1,259 licensed cosmetics production enterprises, 42.07% of Guangdong's total and 23.83% of China's. That count is dated and has likely changed.

The Yangtze River Delta

The Outline of the Yangtze River Delta Regional Integration Development Plan (《长江三角洲区域一体化发展规划纲要》) was issued on 1 December 2019, with a planning period to 2025 and an outlook to 2035. It covers all of Shanghai, Jiangsu, Zhejiang and Anhui, about 358,000 square kilometers, and names 27 central cities. The inclusion of all of Anhui is a common point of confusion: the delta is not only Shanghai, Jiangsu and Zhejiang.

Shanghai is to lead the region's integration and build international economic, financial, trade, shipping and science-and-technology innovation centers. One of the brands the plan promotes is "上海制造" (Shanghai Manufacturing). The Lingang new area of the Shanghai Free Trade Zone is part of the plan.
Suzhou is the model for industrial-park management: the Suzhou Industrial Park cooperative-management model is to be extended across the region. Taicang, within Suzhou, serves as a feeder port for Shanghai container shipping and hosts a China–Germany small and mid-size enterprise cooperation zone.
Ningbo matters chiefly for its port. The plan calls for Ningbo-Zhoushan to become a "modern comprehensive port," with LNG terminals and the Zhoushan oil storage base. Ningbo also hosts the China (Ningbo) "16+1" economic and trade cooperation zone with Central and Eastern Europe.
Yiwu, in Jinhua, Zhejiang, is the subject of a call to accelerate the Yiwu International Trade Comprehensive Reform Pilot Zone, which is also a cross-border e-commerce pilot. This is the official basis for describing Yiwu as a small-commodities trading hub.

Yiwu: a trading hub, not a single production cluster

Yiwu is often described as a place where goods are made. The official plan describes it as a trade-reform pilot zone, and the operator's own figures show a mixed market. Zhejiang China Commodities City Group, which operates the Yiwu market, reports in its 2025 annual report that:

market turnover exceeded RMB 320 billion in 2025;
daily visitors exceeded 230,000, with more than 4,000 foreign-buyer visits a day;
the market offers over 2.2 million kinds of products in 28 categories;
about 52.38% of market merchants have their own factory and about 46.01% have their own brands (end of 2025).

These are company-reported, unaudited operating statistics, and the merchant figures come from the operator's own survey with an undisclosed method. Read plainly, they mean that roughly half of Yiwu merchants report owning a factory and the rest are traders. Many goods sold in Yiwu are made in other cities; the share made elsewhere has not been published. A buyer who finds a product in Yiwu should establish where it is actually manufactured before treating the seller as the producer.

The ports that serve the hubs

Hub location largely determines a shipment's export port. China's Ministry of Transport port statistics, published 30 January 2026, report container throughput for 2025 in TEU (twenty-foot equivalent units, the standard container measure):

Port	Hub region	2025 throughput	Change
Shanghai	Yangtze River Delta	55.06 million TEU	+6.9%
Ningbo-Zhoushan	Yangtze River Delta	43.87 million TEU	+11.6%
Shenzhen	Pearl River Delta	35.41 million TEU	+6.0%
Qingdao	Shandong (outside both deltas)	32.89 million TEU	+6.5%
Guangzhou	Pearl River Delta	27.68 million TEU	+6.2%
Tianjin	Tianjin (outside both deltas)	24.03 million TEU	+3.2%
Xiamen	Fujian (outside both deltas)	12.51 million TEU	+2.1%

All Chinese ports together handled 354.47 million TEU in 2025, up 6.8%. These figures include domestic trade and transshipment boxes, so they measure port scale, not China–US volume. The Shenzhen figure covers Yantian, Shekou, Chiwan and other terminals, and the Guangzhou figure includes Nansha; the ministry does not give terminal-level splits. Shanghai was China's largest container port in 2025, and Ningbo-Zhoushan grew fastest among the majors.

Hubs beyond the two deltas

The two delta plans are the best-documented basis for describing China's hub cities, but production is not confined to them. Product-level data show clusters that cross provincial lines, though the most detailed breakdowns available are dated.

Furniture: in 2010, Guangdong (25.2%), Zhejiang (24.3%), Fujian (13.9%), Shandong (9.6%) and Shanghai (8.1%) produced about 81.2% of China's furniture output, per a 2012 Forest Products Journal study, which places Guangdong's production in Foshan's Shunde district (including Lecong and Longjiang), Dongguan and Shenzhen. The shares are useful for geography, not as current figures.
Solar: the International Energy Agency's 2022 supply-chain report placed most of China's 2021 solar cell capacity in Jiangsu, Zhejiang and Sichuan, and 30% of module capacity in Jiangsu.

Qingdao in Shandong and Xiamen in Fujian appear in the port table above, but the Editorial Desk has no official or academic source for their industrial specialties, or for Chongqing's, and does not state them. The Congressional Research Service reports that the 15th Five-Year Plan, adopted 12 March 2026, prioritizes the economies of Xinjiang and Fujian and rail links with Europe and inland ports; the plan's specific provisions for Xiamen have not been reviewed. With the Yangtze River Delta plan's first horizon ending in 2025, the 15th Five-Year Plan now frames regional priorities.

What a hub's location means for an importer

The region a product comes from shapes three practical things: the export port, the inland transit time to that port, and the likely depth of the local supplier base. A Shenzhen or Dongguan electronics assembler can usually draw on nearby component suppliers; a supplier far from its product's main cluster may be buying in parts from other provinces, which adds time and quality risk.

Three errors are common.

Accepting a city's reputation as proof. Only the specializations named in official plans or statistics are documented above. A supplier's claim that its city is "the" center for a product is a marketing statement.
Confusing a trading hub with a production cluster. Yiwu is officially a trade-reform pilot zone, and about half its merchants report owning a factory.
Drawing the Yangtze River Delta too narrowly. Since the 2019 outline it includes all of Anhui.

Locating the factory itself, rather than the sales office, remains the importer's task. The supplier-verification and factory-versus-trading-company guides cover how that is done from documents.

Frequently asked questions

Where is most manufacturing in China located?

Most is concentrated in two regions: the Pearl River Delta in Guangdong, around Shenzhen, Dongguan, Guangzhou and Foshan, and the Yangtze River Delta around Shanghai, covering Jiangsu, Zhejiang and Anhui. Both received national development plans from the CPC Central Committee and State Council in 2019. Other provinces, including Fujian and Shandong, also have significant clusters for specific products.

Which Chinese city is best known for electronics manufacturing?

Shenzhen, together with neighboring Dongguan. The 2019 Greater Bay Area outline names the two cities as the core of a world-class advanced manufacturing cluster on the Pearl River's east bank, with electronics and information technology as the named example. Shenzhen's port handled 35.41 million TEU in 2025, per China's Ministry of Transport.

What is Foshan known for?

Officially, Foshan is a lead city, with Zhuhai, of the advanced equipment manufacturing belt on the Pearl River's west bank under the 2019 Greater Bay Area outline. The plan also supports a pilot program for comprehensive manufacturing upgrading in Foshan and pairs it with Guangzhou for urban integration. Other specialties often attributed to Foshan are not documented in that plan.

What is Yiwu?

Yiwu is a city in Zhejiang that hosts the Yiwu International Trade Comprehensive Reform Pilot Zone and a large small-commodities market. The market's operator reports turnover above RMB 320 billion in 2025 and over 2.2 million kinds of products. Its own survey says about 52% of merchants have their own factory, so many sellers there are traders.

Which cities make up the Pearl River Delta?

The nine Guangdong cities of the Pearl River Delta are Guangzhou, Shenzhen, Zhuhai, Foshan, Huizhou, Dongguan, Zhongshan, Jiangmen and Zhaoqing. The 2019 Outline Development Plan for the Guangdong–Hong Kong–Macao Greater Bay Area groups those nine cities with Hong Kong and Macao into a single planning region.

What is the largest port in China?

Shanghai, which handled 55.06 million TEU of containers in 2025, according to China's Ministry of Transport. Ningbo-Zhoushan was second at 43.87 million TEU and grew fastest among the major ports, at 11.6%. These totals include domestic trade and transshipment, so they measure overall port scale rather than exports to the United States.
