【摘要】 对农村科技投入与农业经济增长的实证研究以往多是基于线性模型进行的,而实际受诸多因素影响,二者之间可能存在动态的非线性关系.因此使用我国1980-2010年时间序列数据,运用非线性ESTR对这个问题进行研究,结果表明我国农村科技投入与农业经济增长之间存在单向的格兰杰因果关系,两者存在正向非线性关系,表现出阶段性变化特征.其具体分为三个阶段,即增长期1980-1982年、减速期1982-1986年、平衡期1986-2010年.更多还原

【Abstract】 Research on Investment in agricultural science and technology and agricultural economic growth was based on linear model in the past.In fact,affected by some factors,there is a nonlinear dynamic relationship between the two probably.Therefore,time series data from 1980-2010 and nonlinear ESTR model are applied to research the relationship between the two.The results show that there are a one-way granger causal relationship and positive nonlinear relationship between agricultural science and technology and agricultural economic growth.Also it has shown the phase characteristic and been divided into three stages,Growth period from 1980-1982,deceleration period from 1982-1986,balanced period from 1986-2010.更多还原
