The dynamic effect and transmission mechanism of growth and carbon reduction by digital economy stochastic technology shock is studied through the DSGE model that integrates the residents,manufacturers(including digital economy manufacturers)and government.It is found that the shock of digital infrastructure,digital industrialization and industrial digitalization can effectively promote economic growth and alleviate carbon emission intensity and total carbon emission.The investment shock of digital economy can significantly reduce the total amount and intensity of carbon emissions,and positively promote the output and economic growth of digital economy.The stronger the digital economy is in promoting new infrastructure investment,the better the environmental economic effect will be.The restructuring of digital economy can promote the out-put of digital economy and carbon emission reduction.On the whole,different shocks of digital economy,such as technology shock,investment shock of digital economy and structural adjustment of digital economy,show the synergistic effect of growth and carbon reduction.
