Crude oil is the main raw material for the petrochemical industry and a major component of total production costs. It is also an indispensable resource for petrochemical enterprises. The implementation of crude oil e-commerce procurement by petrochemical enterprises can not only reduce the procurement cost of crude oil but also create good economic benefits in the field. It can also establish strategic partnerships with oil field enterprises to lay the foundation for the scientific development of enterprises. Based on the production of Company A and the “10 Million Tons Refining” project, this paper introduces the concept of e-commerce procurement for the problems in all aspects of crude oil procurement management. This paper deeply studies the e-commerce procurement theory, constructs the e-commerce procurement management implementation framework, and proposes that the scientific evaluation of crude oil suppliers is the key idea for petrochemical enterprises to implement enterprise e-commerce procurement management. At the same time, it also conducted an in-depth analysis of the internal and external environment of a company’s crude oil e-commerce procurement, conducted a comprehensive evaluation of existing crude oil suppliers and potential suppliers, and formulated corresponding procurement strategies. Results of the study show the success of the proposed study, and on the basis of the proposed study, researchers can devise new solutions in the field.
