Huizhou Daya Bay Petrochemical Industrial Park

Huizhou Daya Bay Petrochemical Industrial Park is the petrochemical cluster within Huizhou Daya Bay Economic and Technological Development Zone in southern Guangdong. The Daya Bay development zone was approved by China’s State Council in May 1993, and the zone’s official overview describes it as a major petrochemical base on the eastern side of the Pearl River Delta. [1] The Huizhou Industry and Information Technology Bureau identifies the petrochemical zone as a planned 31-square-kilometer area inside the 293-square-kilometer development zone. [2]

The park is an industrial ecosystem rather than a single corporate operating entity. The municipal profile identifies petroleum and chemical production, port logistics, electronics, automobile components, and equipment manufacturing among the zone’s priority industries, and reports refining capacity of 22 million tonnes per year and ethylene capacity of 2.2 million tonnes per year. [2] Guangdong’s green-petrochemical action plan identifies the Daya Bay base as one of the province’s principal petrochemical bases, led by CNOOC Huizhou Petrochemical, CNOOC–Shell ethylene, and the ExxonMobil Huizhou ethylene project, with an emphasis on connected upstream, midstream, and downstream chains. [3]

CNOOC and Shell Petrochemicals Company, or CSPC, is one of the anchor enterprises in the park. CSPC says it was established in 2000 as one of China’s largest petrochemical joint ventures and that its operations place health, safety, and environmental management at the center of the business. [4] The company’s public materials also say that its Huizhou Phase 3 ethylene and polycarbonate projects entered full-scale construction after a final investment decision in 2024. [4]

The park’s recent scale is reflected in a Guangdong government foreign-affairs profile that says it hosted 125 projects with total investment of 332.4 billion yuan and attracted 13 Fortune Global 500 companies; the same source says it ranked first among China’s Top 30 Chemical Parks for six consecutive years from 2019 through 2024. [5] These figures describe a shared production and logistics platform whose development depends on feedstock integration, downstream materials demand, coordinated utilities, and continuing safety and environmental oversight.
