The business of SINOPEC covers E&P of oil and gas, refining,chemical production, as well as sales and marketing of refined oil products. In the field of oil andnatural gas exploration and development, there are 13 upstream subsidiaries in SINOPEC. By the endof 2003, the proven reserves of crude oil were 3,257 mmbbls, and natural gas reserves totaled2,887.6 bcf. The oil and gas production in 2003 included 270.96 mmbbls of oil and 187.7 bcf ofnatural gas. In the area of middle-stream operation, SINOPEC has 33 refineries. The total capacityof crude distillation is 153.9 million tons/year, about 51% of the total distillation capacity inChina. In 2003, 123.5 million tons of crude oil was processed, around 53% of total crude processedin China.展开更多
The research performed analysis on causes of asymmetric information of agricultural product supply chain and made conclusion on operation mechanism and characteristics of supply chain based on asymmetric information. ...The research performed analysis on causes of asymmetric information of agricultural product supply chain and made conclusion on operation mechanism and characteristics of supply chain based on asymmetric information. Finally, the research detailed profit sharing of agricultural product supply chain in the context of asymmetric information and proposed suggestions, providing references of pricing and profit sharing of supply chains of agricultural products.展开更多

That the supply chain system structure, with the variance of the rate of re-production input funding, becomes unstable is proved. Noticeably, the solutions shows that when the optimal combination of input parameter element, the qualitative properties of supply chain system change and the supply chain system becomes unstable.展开更多
