Abstract: The dynamic economic analysis was adopted to evalute the economic benefits from the cultivation of the fast-growing and high-yielding Chinese Fir plantation. The results showed that there was a remarkable economic benefit from the cultivation of the plantation. The maximum net benefit investment ratio, inter rate of return (IRR), and net present value might be 3.15, 19.5%, and 5275.35 yuan/ha respectively, and the minimum ones 1.60, 15.2%, and 1 392.75 yuan/ha respectively. The results also indicted that the internal rate of return was still higher than the basic rate of return while the 7 parameters were changed, such as a drop in timber price by 20%, or a rise in cutting cost by 20%. The cultivation of the fast-growing and high-yielding Chinese Fir plantation could endure the risk of a rise in total cost by 58% or a drop in net benefit by 36%.
