This dataset is a market activity dataset representing the crude oil consumption mix in the region. Markets group together producers and imported products within the same geographic area (if relevant). They also account for transportation (distribution) to consumers and associated losses during the process (if relevant). This is the crude oil market for the China region, with the consumption structure calculated based on China Customs statistical data and international crude oil production statistics. Import and export flows as well as intercontinental maritime transport are included, with long-distance crude oil transportation referencing Meili et al. (2022, p. 3. Section 4), this information describes the modeling approach for transporting crude oil from the extraction site to the destination port via pipelines or tanker ships. The average transportation distance within China is also included, where crude oil is primarily transported via waterways and pipelines. Data sources include the China Communications Yearbook, China Energy Statistical Yearbook, China Statistical Yearbook, and customs statistics from the General Administration of Customs.
