A survey is conducted to collect information about whether there is money-environment substitution effect in college students＇ attitude to environmental protection and the domain difference of discounting rate of money and the environment. Results shows that the money-environment substitution effect does exist in college students＇ attitude to environmental protection, and the environmental outcomes are discounted significantly faster than monetary results; moreover, the difference of discounting rate of monetary and environmental fields in a profitable scenario is more significant than that in a loss-generating scenario. In conclusion, college students are more inclined to pay money to protect their environment;compared with monetary affairs, they pay more attention to the present outcome instead of the long-term consequences of environmental events; the discounting rate of participants is more sensitive to the change of domain in a profitable scenario than that in a loss-generating scenario.
