I. Why the Geography of Chemical Investment Matters

The map of chemical investment is a more direct signal than any policy document. When a province concentrates a large number of projects within a given time window, it reflects the compounding of four forces: resource endowments, policy environment, infrastructure, and supply-chain depth — no single factor alone drives the outcome.

By project count across active construction and planned pipelines in 2024, the East China region leads all major zones with 78 projects. Behind that figure lies the dense deployment of Shandong, Jiangsu, and Zhejiang across refining and chemicals, new materials, specialty chemicals, and biopharma. Meanwhile, in the Northwest, Inner Mongolia and Xinjiang have moved into substantive construction on mega-scale coal-chemical bases. In South China, Guangdong and Guangxi are steadily expanding along two tracks: integrated refining-and-chemical complexes and downstream specialty chemicals.

This map is being redrawn by policy. The stabilization plan for the petrochemical and chemical industry issued jointly by seven ministries explicitly requires that by 2025, "progress in shifting from oil products to chemicals" be achieved, with the share of refined oil output in new integrated projects falling to below 40% of crude throughput. The pressure to convert refining capacity toward higher-value chemical products is visible throughout the provincial project lists.

II. East China: The Densest Battleground

East China accounts for roughly one-third of all active chemical construction projects in China, with Shandong, Jiangsu, and Zhejiang representing three differentiated pillars across the region.

Shandong: From "Big Refining" to High-Value Chemicals

Shandong holds the highest number of recognized chemical parks nationwide, reaching 85 parks by 2024. This scale is the product of decades of accumulation and simultaneously the source of the greatest pressure for park consolidation and upgrading.

The most closely watched Shandong project in 2024 is the Yulong Island integrated refining and chemical complex. This is the single largest industrial investment project in Shandong's history, with a Phase 1 approved total investment of approximately RMB 116 billion. Core facilities include 20 million tonnes per year of refining capacity and 3 million tonnes per year of ethylene, with downstream polyethylene and polypropylene derivatives. The first series of oil-processing units began start-up in late September 2024, with chemical processing units following in subsequent months. Yulong Island's significance lies not just in scale, but in its strategic function: consolidating fragmented independent refinery capacity into an integrated chain extending from naphtha and LPG feedstocks toward aromatics, olefins, and advanced materials.

Wanhua Chemical's new materials low-carbon industrial park Phase 1 also completed commissioning during this period. Wanhua has established global competitive standing in isocyanates (MDI and TDI) and continues to extend downstream at its Yantai base into specialty chemicals and new materials, representing Shandong's leading edge in high-value chemical manufacturing.

Jiangsu: Lianyungang's Trillion-Yuan Ambition

Jiangsu's chemical industry is characterized by a relatively high degree of specialty chemical content. The fine chemical rate at Taixing Economic Development Zone exceeds 66%, and specialty chemicals account for a growing share of the province's industrial output. The largest single investment in Jiangsu's 2024 active pipeline belongs to the Lianyungang Xuwei New Area, where Satellite Chemical announced in June 2023 plans to invest approximately RMB 25.7 billion to build an alpha-olefin comprehensive utilization and high-end new materials industrial park, producing alpha-olefins (LAO), polyethylene, and downstream derivative materials. The Xuwei New Area's official target is cumulative industrial investment exceeding RMB 800 billion by 2030, with a goal of developing a trillion-yuan petrochemical cluster.

Additionally, Jiangsu claimed 10 of the 100 spots in the 2024 High-Quality Development Chemical Park ranking — the most of any province — reflecting the province's lead in park governance and operational standards.

Zhejiang: Specialty Chemicals and New Materials as the Core Axis

With 51 recognized chemical parks and established strengths in synthetic fibers, coatings, and specialty chemicals, Zhejiang has built a fundamentally different industrial structure from Shandong or Jiangsu — centered on formulation-based chemical products and differentiated new materials rather than base olefins. Active projects are concentrated in higher-value, smaller-scale products such as powder coating polyester resins, waterborne adhesives, and new energy functional materials.

III. Northwest China: Mega-Scale Coal Chemical Ambitions

If East China has the highest density of chemical projects, the Northwest holds the largest single-project scale. Inner Mongolia and Xinjiang are pushing the chemical industry frontier westward, leveraging abundant coal and natural gas resources.

Inner Mongolia: The Ordos Coal Chemical Demonstration Base

Ordos is one of China's four national demonstration zones for modern coal chemicals, with existing coal-to-oil, coal-to-methanol-olefin, and related chains yielding an annual production capacity approaching 20 million tonnes. In 2023, the Rongsheng green integrated coal chemical project — with planned total investment exceeding RMB 160 billion — was signed in Zhunge'er Banner, targeting coal gasification, high-end polymer materials, acrylic acid and esters, and related new materials. This is among the largest single coal-chemical investments in Inner Mongolia in recent years.

The active project list from Inner Mongolia includes coke oven gas utilization, organosilicon, coal-to-gas, coal-to-chemicals, and specialty materials (silicon-carbon anode materials, battery materials), reflecting the province's push to extend coal chemistry downstream into fine chemicals and new materials.

Xinjiang: Entering an Investment Peak

Xinjiang is emerging as the most important incremental growth zone for coal chemicals in China. Notable projects include the National Energy Group Hami Energy Integration and Innovation Base, which formally began full-scale construction in October 2024 with a total planned investment of approximately RMB 170 billion. Its core process employs domestically developed second-generation direct coal liquefaction technology. Phase 1 is scheduled for completion by end-2027. Alongside this, multiple green hydrogen projects are converting Xinjiang's abundant wind and solar power resources into hydrogen and synthetic ammonia, forming a complementary track to conventional coal chemistry.

Additional hundreds of billions in coal-to-olefins and coal-to-gas projects remain in the planned pipeline. Industry analysis suggests Xinjiang's coal chemical sector is entering a multi-year investment high.

IV. South China: Two Strategies in Guangdong and Guangxi

South China's chemical landscape is anchored by two major bases — Huizhou Dayawan in Guangdong and Qinzhou in Guangxi — with meaningfully different strategic orientations.

Guangdong Huizhou: Positioning as a Global Petrochemical Hub

Dayawan Economic and Technological Development Zone has established itself as one of China's most concentrated refining and chemical zones, with built capacity of 22 million tonnes per year of refining, 3.8 million tonnes per year of ethylene, 2.5 million tonnes per year of aromatics, and 5 million tonnes per year of PTA. In 2024, Huizhou's new materials industrial park signed 20 new projects totaling RMB 25.9 billion in investment, including Germany-headquartered specialty chemical firms and major expansions by joint ventures already on site. The Huizhou strategy uses large-scale refining as the base-feedstock platform, then builds outward into specialty chemicals, electronic chemicals, and high-end new materials.

Guangxi Qinzhou: Integration as the Strategic Spine

Guangxi Huayi's Qinzhou chemical new materials integrated base has a total planned investment of approximately RMB 100 billion, with Phase 3's first batch of facilities beginning construction in March 2024. Simultaneously, Guangxi Petrochemical's integrated refining upgrade project is proceeding in parallel; combined, the two projects represent investment of over RMB 130 billion — the largest construction concentration in Guangxi's chemical industry history. Guangxi's proximity to ASEAN markets gives Qinzhou-produced chemicals a logistics advantage over inland provinces for export.

V. Driving Forces: Policy Push and New Materials Pull

Two clear structural forces explain the 2024 project pipeline.

The first is policy-driven structural adjustment. The requirement that new integrated refining projects hold the refined-oil share of crude throughput below 40% means every major new project must, from the design stage, plan a sufficiently deep downstream chemical product slate. Yulong Island and Rongsheng's Zhenhai base were both conceived around a defined chemical product portfolio first, with refining capacity sized accordingly — not the other way around. This policy dynamic is accelerating the structural conversion of national refining capacity toward high-end chemical materials.

The second is new-materials demand pull. The four chains of new energy vehicles, lithium batteries, photovoltaics, and electronics semiconductors require not commodity chemicals but application-specific materials with demanding purity, performance, and consistency specifications — electrolyte additives, silicon-carbon anode materials, electronic-grade chemicals, photovoltaic encapsulant films, and polyolefin elastomers (POE). The active project lists for Jiangsu, Zhejiang, Hubei, and Guangdong contain a significant number of smaller-scale projects targeting exactly these specialty segments. Individually modest at RMB 100 million to 1 billion in investment, they collectively constitute the capillary network of China's specialty chemicals domestic substitution.

VI. Risks and Outlook

Regional concentration of chemical investment is both a source of scale efficiency and a mechanism for risk accumulation. The high concentration of projects in Shandong, Jiangsu, and Inner Mongolia means that if multiple large projects come online in the same downcycle, localized oversupply will materialize quickly. The softening of certain bulk chemical prices since 2022 has already demonstrated this dynamic.

The economics of Northwest coal-chemical bases depend heavily on maintaining a long-run spread between coal input costs and chemical product prices. The return on the Hami base and comparable projects will only be verifiable after 2027 commissioning, against market conditions that cannot be fully anticipated today.

For the downstream new-materials extensions attached to olefin and aromatics chains, competition is already intense. The "premium window" for a newly commercialized specialty product — the period when differentiation supports pricing above commodity — typically spans three to five years before competitors arrive. Sustained research and development investment and rapid product iteration are prerequisites for profitability, not scale alone.

The Tianxia Gongchang Industrial Research Institute's assessment is: the 2024 chemical construction project map shows a pattern of "dense East, mega-scale Northwest, value-chain completion in South China." The differentiated competitive opportunities within this map are concentrated at the product inflection points where bulk commodity chemicals transition to high-value specialty chemicals. Those who reach these inflection points ahead of the field — whether enterprises or industrial parks — will retain a market timing advantage of at least five years.
