Considering the low-carbon technology spillover, the three-stage game model shows that the equivalent carbon price is not a definite value, but a variable in the certain interval. Meanwhile, the carbon emission limit and time are relevant to determine the balance of the carbon price. At first time, the lowest price may be higher in order to promote the large enterprises to invest in low carbon production technology. After a certain period, the Government can reduce the price appropriate in order that can avoid the low-carbon technology transfer fee is too high and prevent the formation of low-carbon technology monopoly.
