The invention belongs to the technical field of measurement, and discloses a device and a method for measuring an annulus permeability coefficient in a gas transmission hose. Comprising a methane gas cylinder, a pressure pump, a first gas flowmeter, a first ball valve, a pressure gauge, an inlet, a water bath controller, a data collection system, a first pressure sensor, a gas conveying hose, an outlet, a second gas flowmeter, a second ball valve, a third ball valve, an emptying valve, a circulating pump, a waste gas collector, a fourth ball valve and a second pressure sensor. The methane gas cylinder is sequentially connected with the pressure pump, the first gas flowmeter, the first ball valve, the pressure gauge and the inlet; and the outlet, the second gas flowmeter, the second ball valve, the circulating pump, the fourth ball valve, the pressure gauge and the inlet form a circulating loop. The real working condition of the gas transmission hose under the actual working condition is simulated through the
