Introduction
When China Petroleum & Chemical Corporation (Sinopec) is mentioned, most people immediately think of its gas stations. Nevertheless, the group’s business scope stretches far beyond fuel retail. It processes 250 million tons of crude oil and produces 13.47 million tons of ethylene annually, operates over 30,000 gas stations, and conducts business across more than 90 countries and regions. This article analyzes this Fortune Global 500 No.6 energy and petrochemical conglomerate with detailed operational statistics and business breakdowns.
Core Key Metrics of Sinopec Group
- Total employees: ~520,000
- Total assets: RMB 2.74 trillion
- Annual operating revenue: RMB 3.14 trillion
- Global ranking: 6th on Fortune Global 500
- No.1 global crude oil refining capacity
- No.2 global ethylene production capacity
- Total gas stations: 31,000
1. Development History: From State Petrochemical Corporation to Global Top 6 Enterprise
Sinopec’s history dates back to 1983, when the State Council established China Petrochemical Corporation to coordinate national petrochemical production, construction, import and export businesses. In July 1998, the central government restructured the original corporation into Sinopec Group, marking the geographic split between Sinopec and PetroChina: PetroChina took charge of oil and gas fields in northern and northwest China, while Sinopec acquired refineries in eastern and southern China.
- 1983: China Petrochemical Corporation founded under direct administration of the State Council
- 1998: Restructured into Sinopec Group; geographic asset split with PetroChina
- 2000–2001: Sinopec Corp. launched IPOs in Hong Kong, New York, London and Shanghai, setting a precedent for multi-listing
- 2018: Completed corporate system reform, transforming from an ownership by the whole people enterprise to a solely state-owned enterprise
- 2025: Hou Qijun appointed Chairman; the Group rolled out the "One Base, Two Wings, Three New Growth Drivers" strategy
Registered capital stands at RMB 326.5 billion, with SASAC holding 100% equity stake. It ranked 6th in the 2025 Fortune Global 500 list.
2. Four Core Business Segments: Full Industrial Chain from Upstream Oil Extraction to Downstream Chemical Sales
Public perception of Sinopec is limited to fuel refueling, yet its business is divided into four major segments, each ranking among industry leaders globally.
2.1 Oil & Gas Exploration and Production – High-profit Cash Cow
This segment forms Sinopec’s core profit source, with a gross profit margin of 16.91%. In 2024, its oil and gas equivalent output reached 515 million barrels (approximately 70 million metric tons), including domestic crude oil output of roughly 35 million metric tons and natural gas output of 39.6 billion cubic meters. Construction of national demonstration zones for ultra-deep shale gas in the Sichuan Basin and Jiyang shale oil in Shengli Oilfield has been advanced efficiently.
- Oil & gas equivalent output: 515 million barrels
- Natural gas output: 39.6 billion cubic meters
- Operating income of oil & gas segment: RMB 56.4 billion
2.2 Crude Oil Refining – World’s Largest Capacity with Slim Profit Margins
Sinopec boasts the world’s No.1 crude oil refining capacity. In 2024, it processed 252 million tons of crude oil and produced 153 million tons of refined oil products. However, the refining segment only posted a gross profit of RMB 304 per ton, corresponding to a gross profit margin of merely 0.37%, operating nearly at break-even point. The full-year operating income hit RMB 6.7 billion, a year-on-year decrease of RMB 13.9 billion.
Reasons for low refining profitability
Volatile international crude oil prices, shrinking cracking spread of jet fuel, and higher crude import costs driven by exchange rate fluctuations. Despite massive throughput, the refining business generates minimal profit and functions largely as a throughput service.
2.3 Refined Oil Product Sales – Ground Network with 30,000+ Gas Stations
Sinopec runs 30,987 branded gas stations nationwide. In 2024, total refined oil sales volume reached 239 million tons, including 183 million tons sold domestically. The segment recorded a gross profit margin of only 1.01% and operating income of RMB 18.6 billion.
Non-fuel businesses deliver remarkable performance: convenience store services under Easy Joy contributed gross profit of RMB 11.1 billion; charging service fees reached RMB 430 million (up 20 times year-on-year), with total charging volume hitting 1.8 billion kWh (up 21 times year-on-year). Its marine bunkering business ranks second globally.
- Total gas stations: 30,987
- Charging & battery swapping stations: 10,000+
- Gross profit from convenience store business: RMB 11.1 billion
2.4 Chemical Production – World’s No.2 Capacity with Temporary Losses
Sinopec ranks first in China and second globally in ethylene capacity. In 2024, ethylene output hit 13.47 million tons, synthetic resin output 20.09 million tons, and synthetic rubber output 1.43 million tons. Total chemical product sales volume reached 83.45 million tons, with export volume rising 13.1% year-on-year.
Nevertheless, the chemical segment posted an operating loss of RMB 10 billion in 2024, with a gross profit margin of -2.55%. The downturn stemmed from continuous new capacity rollout across the domestic industry and sharply narrowed gross margins, alongside industry-wide price competition despite record-high PX production volume.
Key Chemical Product Output (2024)
- Ethylene: 13.47 million tons
- Synthetic resin: 20.09 million tons
- Synthetic rubber: 1.43 million tons
- Synthetic fiber: 1.25 million tons
