摘　　要：通过协整检验、Granger因果检验、脉冲响应以及方差分解等方法,选取我国农业1999~2016年相关宏观经济数据,对我国农业技术进步的基本类型与农业总产出之间的动态关系展开研究。研究结果表明,技术创新、技术引进以及技术模仿与我国农业产出有着长期的协整关系,但不同路径对农业产出影响程度不同:技术创新对农业产出的影响具有长期性,并逐渐变为主导。技术引进与技术模仿对农业产出的贡献逐渐增强,但其贡献率增长幅度低于技术创新。Through the methods of cointegration test,Granger causality test,impulse response and variance decomposition,we select the relevant macroeconomic data of China's agriculture from 1999 to 2016 to study the dynamic relationship between the basic types of agricultural technological progress and the total agricultural output.The results show that there is a long-term cointegration relationship between technological innovation,technology introduction and technology imitation and agricultural output in China,but the impact of different paths on agricultural output is different:The impact of technological innovation on agricultural output is long-term and gradually becomes dominant.The contribution of technology introduction and technology imitation to agricultural output has gradually increased,but the growth rate of its contribution rate is lower than that of technological innovation.
