| 摘 要： | 协整检验的结果表明,农业科研投入与农业总产值在整个研究期间内(1986—2003年)是不协整的;而通过引入虚拟变量,把研究期间分为1985—1995和1996—2003年两个阶段,在各分阶段上两者是协整的;格兰杰因果检验的结果表明,两者存在双向因果关系,农业科技投入是农业经济发展的原因,但农业总产值的增加并没有明显地促进农业科研投入的增加,反映出我国农业科研投入机制还存在深层问题。 |
| 关 键 词： | 农业科技投入 单整检验 协整检验 虚拟变量 格兰杰因果关系检验 |

| Abstract: | The result of Cointegration test indicates that the long-term and balanced connection doesn't exist in Gross output value of Agriculture and Agriculture Technological Investment in the whole of research course(1986-2003).But after introduced in dumb variable of mechanism,the long-term connection exists in 19861995 and 1996-2003.The result of Granger test signifies that Agriculture Technological Investment Granger Cause Gross output value of Agriculture and Gross output value of Agriculture Granger Cause Agriculture Technological Investment,but this trend is not evident.This result also signifies that there are some underlying problems lies in the mechanism of Agriculture Technological Investment. |
| Keywords: | Agriculture Technological Investment Integration Test Cointegration Test Dumb variable Granger causality test |
