Abstract: Traditional concept assumes that hydrocarbons are primary and limited non renewable resources. Inorganic origin theory re-gards generation of hydrocarbons as nearly limitless resources. While according to synthetic origin theory with CO, CO₂ and H₂, inorganic origin theory established by carbonide petrochemistry and biological origin theory, hydrocarbons are considered to be renewable. This pa-per describes the relationship between organic and inorganic origin theories from historical and philosophical viewpoints, and points out that there is not an impassable gap between inorganic origin field and organic origin field. China^s continental crust is in special environ-ments of geodynamics, which allowed deep mantle materials to extensively participate in hydrocarbons-generating processes, providing e-nough conditions for multiple element origins. Therefore, to develop inorganic origin theory, synthetic origin theory and biological origin theory is the need or requirement for sustainable development of oil-gas resources.
