Abstract: On the basis of Cobb-Douglas production function and the time-series date of Shandong province from 2000 to 2017, the establishment of VAR (Vector Autoregression model) is to explore the dynamic correlation between agricultural economic growth and input factors in Shandong province by exercising IRF (Impulse Response Function) and VD (Variance Decomposition) with the collected date of agricultural workforce in Shandong province, agricultural mechanization level, scientific input in agriculture field. The result showed that agricultural workforce obviously promotes the agriculturaleconomic growth in Shandong province.However, this influence is gradually weakening. The total power of agricultural machinery and the input of fixed assets in agriculture-related fields have obvious lag effect on agricultural economic growth, yet have an evident promoting effect in the long run.
