Regional Dynamics in China’s Silk Industry: A Guide for Foreign Sourcing Decisions

China’s silk industry is geographically diverse. The same national label conceals significant differences in cost structure, specialisation, policy support and operating conditions across provinces. For foreign buyers the practical consequence is straightforward: the optimal sourcing location depends on whether the requirement is raw silk, greige fabric, finished apparel or a branded collaboration. Understanding the regional map is therefore a basic input into any serious procurement or investment decision.

1 Where the Industry Actually Operates

The China Silk Association’s second-quarter 2026 survey drew responses from enterprises in 15 provinces and municipalities. Five provinces and regions alone accounted for roughly 72 % of the sample:

These percentages reflect the distribution of responding enterprises rather than pure production volume, yet they correctly highlight the main centres of activity. Chongqing, Jiangsu, Zhejiang, Guangxi and Anhui together form the core of both the survey sample and the industry’s operational geography.

2 The Emerging East–West Division of Labour

National policy has for years encouraged a clearer regional specialisation, most recently under the “East Silk, West Consolidation” (东绸西固) framework. The intended pattern is simple:

• Western and southwestern regions concentrate on silkworm rearing, cocoon production and primary reeling, leveraging lower land and labour costs and favourable climatic conditions.
• Eastern coastal regions focus on higher-value processing, design, branding, technical textiles and international trade.

In practice the division is not absolute—some eastern provinces still maintain significant rearing capacity, and western areas are gradually adding more fabric and even garment capability—but the direction of travel is clear. Foreign buyers who align their sourcing strategy with this specialisation generally obtain better cost-to-quality outcomes than those who treat “China” as a single undifferentiated supply base.

3 Western Powerhouses: Cocoon and Primary Processing

Guangxi stands out as the single most important cocoon-producing region in China. In 2025 the autonomous region produced approximately 50.5 million tonnes of cocoons, accounting for more than 60 % of the national mulberry-cocoon total. It has held the top national ranking for more than two decades. Supporting clusters in Sichuan, Yunnan and Chongqing add further scale, so that the broader western and southwestern zone now supplies the large majority of China’s raw cocoons.

Advantages of sourcing primary materials or basic reeling from these areas include:

• Lower land and labour costs relative to the eastern seaboard
• High concentration of specialised rearing households and cooperatives
• Policy support under both national “East Silk, West Consolidation” measures and local industrial-cluster programmes

Limitations also exist. Deep processing, high-end dyeing and finishing, and sophisticated design capabilities remain thinner than on the coast. Lead times for complex finished products can be longer, and international logistics connections, while improving, are generally less dense than those of Zhejiang or Jiangsu.

4 Eastern Strengths: Processing, Branding and Trade

Zhejiang and Jiangsu remain the traditional heartland of silk processing, trading and brand activity. Even as cocoon production has shifted westward, these provinces retain dense networks of weaving mills, dyeing and finishing plants, design studios, trading companies and export-oriented manufacturers. Chongqing, while geographically more central, also functions as an important processing and trading node with strong enterprise representation in the survey.

Eastern advantages for foreign buyers typically include:

• Greater depth in fabric construction, dyeing, printing and garment manufacturing
• Stronger design and product-development capabilities
• More experienced export teams and established compliance documentation
• Better access to international logistics and trade-show ecosystems

The corresponding trade-offs are higher operating costs—especially labour and land—and, in some cases, greater exposure to the recruitment difficulties that rank as the industry’s top operating concern nationwide.

5 How Costs, Support and Performance Differ by Region

Three practical differences matter most to overseas decision-makers.

Cost structure
Western rearing and primary-processing bases generally enjoy lower wage and land costs. Eastern processors face higher absolute costs but often achieve better productivity per worker and higher value capture through branding or technical products.

Policy intensity
Both national and local governments are actively supporting the industry, yet the instruments differ. Western provinces receive more support aimed at capacity expansion, standardised plantations and primary-processing upgrades. Eastern provinces receive relatively more encouragement for R&D, brand building and high-end product development. Local packages—such as the detailed measures issued in Nanchong (Sichuan)—can further tilt the balance for specific cities or clusters.

Operating resilience
Medium-sized and larger enterprises, which dominate the survey sample, are present in both east and west. However, the denser ecosystem of supporting services, finance and skilled labour in the east can make it easier for firms there to absorb short-term shocks. Western producers of raw materials benefit from scale and policy tailwinds but may be more exposed to weather, disease and labour-availability risks at the farm level.

6 Matching Product Type to Optimal Sourcing Region

A simple decision framework helps align product requirements with regional strengths:

• Raw silk or basic yarn – Prioritise Guangxi, Sichuan, Yunnan and related western clusters where cocoon volume and primary reeling capacity are concentrated.
• Greige or finished fabrics – Look first to Zhejiang, Jiangsu and established processing centres in Chongqing or selected western cities that have upgraded weaving capacity.
• Finished apparel, home textiles or branded products – Eastern partners generally offer stronger design, quality-control and export-service capabilities; joint development projects also tend to run more smoothly there.
• Long-term investment or joint-venture projects – Evaluate both the cost advantages of western locations and the ecosystem advantages of the east, then verify the specific legal entity, ownership and operating status of any candidate partner.

In every case, confirming that the actual production site matches the claimed location remains essential. Industrial-transfer projects and multi-province groups can create discrepancies between a company’s registered address and its real manufacturing footprint.

Regional differences inside China’s silk industry are large enough to affect cost, lead time, quality consistency and long-term partnership risk. The survey data, production statistics and current policy framework all point to a continuing specialisation: the west supplies the bulk of cocoons and primary silk, while the east leads in higher-value processing, design and international trade. Foreign buyers and investors who map their requirements onto this geography—and who verify the precise location, ownership and operating status of each potential partner—will make more durable sourcing decisions than those who approach the market as a single undifferentiated whole.
