摘要
本文利用企业动态经济分析方法进行了杉木速生丰产林栽培经济评价。结果表明,营造杉木速生丰产林的经济效果十分明显,净效益投资比最高可达3.15,最低也达1.60,内部收益率最高可达19.5％,最低也在15.2％以上;公顷净现值最高达5 275.35元,最低可达1 392.75元。不确定性分析表明,在木材价格下降20％或采伐成本提高20％等七种不利情况下,内部收益率均大于基准收益率。转换试验进一步表明,营造杉木速生丰产林最大承受风险的能力为总成本提高58％或净效益下降36％。
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 %.
