The invention discloses a transcritical circulation cooling heat and power cogeneration system employing CO2 as a working medium. The system comprises a cooling system, a power generation system, a heating system and a gas heater, wherein the cooling system comprises a compressor, an evaporator, an ejector, a throttling valve and a gas-liquid separator; the heating system comprises a heater and a gas cooler; the power generation system comprises an intermediate extraction expander and a power generator. According to the system, an extensive low-grade heat source is used for heating the CO2 working medium, the power generation system applies work to generate power through the expander, and a part of expansion power is recovered; the heat of the CO2 working medium at an outlet of the expander is supplied to a user; an ejection cooling mode is used for cooling; a combined design of the intermediate extraction expander and the ejector is adopted on the basis of a transcritical CO2 compression cooling system, the gas heater is additionally arranged, and the low-grade heat source is utilized, so that cooling heat and power cogeneration is realized.
