Accelerating the realization of carbon peak and carbon neutralization is of great significance to the sustainable development of economy and societyIncreasing service factor inputs and activating the production factor market provide a feasible path to achieve green upgrading in Global Value Chain(GVC)Whether service factor inputs in manufacturing sectors could relieve the carbon emission pressure of export has become a major issue for urgent solutionThe paper measures carbon emission intensity index of export from the perspective of actual gains and environmental cost of GVC participationOn this basis,we empirically analyze the impact of service factor inputs in manufacturing on embodied carbon of export,and further empirically test the impact mechanismThe result shows that the service factor inputs in manufacturing sectors reduces the export carbon emission intensity,which effect on embodied carbon emission through factor allocation effect,technical progress effect and carbon transfer effectTherefore,increasing service factor inputs in manufacturing sectors should be a key point of supply side reform
