农业科技投入与农业经济发展关系的分析

摘要

利用向量误差修正模型（VEC）研究了我国1986-2012年农业科技投入和农业经济发展之间的长短期因果关系。研究结果表明，农业科技投入和农业总产值之间存在双向因果关系，并且在长期维度保持一定稳定关系；在短期维度上农业科技投入和农业产值之间在滞后二期上保持双向的短期因果关系。基于此结论提出增加农业科技投入和完善农业科技创新体制的政策建议。%Vector error correction model (VEC) is applied to measure the relationship between 1986-2012 years of Chinese investment of agricultural Research and Development and the development of agricultural economy in this paper. hTe results suggest that there is a two-way causal relationship between agricultural science and technology input and agricultural output. In addition, there are two-way short-term causal relationship between agricultural science and technology input and agricultural output value in two period lag. We put forward policy suggestions of increasing the investment of agricultural science and technology and perfecting the agricultural science and technology innovation system at the end of this paper.
