基于投入产出模型的林业产业发展动态分析

根据新的林业产业分类,运用2002和2007年中国投入产出表及中国林业统计年鉴的基础数据,构建了林业产业的投入产出分析模型,对林业产业的发展动态进行比较分析。结果表明:林业增加值绝对额显著增加,占国民生产总值的比例增长,林业产业对中国经济的贡献率增长明显;大部分林业产业属于劳动密集型产业;整个林业产业呈现中间产品的性质,部分林业产业的成本效益变化不大;应重点发展投入小而价值高的木竹浆造纸及纸制品业等产业。

Dynamic Analysis of China Forestry Industries Development Based on the Input-Output Model

According to the adjusted forestry industries classification,it used the Input-Output tables of China in 2002 and 2007,and forestry statistical yearbooks of China to create the input-output model about china’s forestry industries,and have dynamic comparison analysis about China’s forestry industries development,it shows that the forestry absolute production values significantly increases,and the proportion of forestry total values among the GDP has obvious increase;most of the forestry industries belongs to the labor-intensive industries;meanwhile,the whole forestry industry show that the forestry industries have the characteristics of intermediate product;the forestry industries with low input but high value should be focused based on the cost-efficiency analysis.
