Abstract: Agricultural production efficiency is an important index for the high-quality development of agriculture.In order to improve the efficiency of agricultural production and accelerate the process of agricultural modernization in Shanxi Province,the evaluation index system of agricultural production efficiency in Shanxi Province based on the data of time section in 2009,2013,and 2017 was constructed.Using the three-stage DEA model to measure the agricultural production efficiency of 11 cities in Shanxi Province,and by using ArcGis visualization technology to analyze its space characteristics.The results showed that the score of the agricultural production efficiency of 11 cities in Shanxi Province is 0.5-1.0 without considering the situation of disturbance of the environmental factors and random factors.With the passage of time,the leading factor that affects the agricultural production efficiency of Shanxi Province changes from a pure technical efficiency to a scale efficiency;the intermediate consumption of agriculture,forestry,animal husbandry and fishery that affects the agricultural production efficiency of Shanxi Province gradually tends to be rationalized;by comparing the value of the agricultural production efficiency of Shanxi Province in the first stage and the third stage,a significant difference is found,which indicated that the agricultural production efficiency of Shanxi Province is indeed affected by an external objective environment and random error;In 2009,2013 and 2017,the agricultural production efficiency in Shanxi Province showed obvious spatial clustering characteristics.There are some specific suggestions to ensure the improvement and development of agricultural production efficiency in Shanxi Province.
