The invention provides a method of wave cracking of a macro-molecular organic matter. Repeating units containing a carbon-carbon chemical bond in the organic matter generate resonance under the action of a radiation wave, so breakage of the carbon-carbon chemical bond is formed under resonance conditions; thus, oriented formation of cracking reactions of micro-molecular organic matters is realized so as to improve the cracking rate and the conversion rate of organic matters in industrial and household garbage, thereby allowing a recyclable energy product to be obtained. According to the method, the radiation wave with a wavelength in a range of 0.1 micrometer to 1.0 meter is introduced into a sealed container in which the solid or liquid macro-molecular organic matter is disposed; the radiation wave irradiates on the surface of the organic matter and penetrates into the interior of the organic matter, which causes generation of resonance by the repeating units containing the carbon-carbon chemical bond in the organic matter; and frequency and irradiation time of the radiation wave are controlled so as to allow the carbon-carbon chemical bond to undergo breakage under the resonance conditions, and the macro-molecular organic matter is decomposed into a gaseous low-carbon organic matter, a liquid medium-carbon organic matter and a solid high-carbon organic matter.
