摘要
对1991～2008年样本区间内我国历年造林面积与林业投入进行了协整分析,用格兰杰因果检验对两个变量之间的因果关系进行了检验。结果表明,1991-2008年样本区间内历年造林面积与林业投入存在长期的均衡关系,同时样本区间内,历年造林面积（AREA）和林业投入（INPUT）存在单向的因果关系。
The co-integration analysis was conducted to the relationship between afforestation area and input to forestry during 1991-2008 in China, and the causality between them was tested by Granger test of causality. The results showed that there was a long-term balanced relationship between afforestation area and input to forestry during 1991-2008 in China, meanwhile, there was a unidirectional causality between them.
