Abstract:

In order to evaluate of input-output efficiency of agricultural production, provide practical guidance to promote sustainable agriculture in low yield in Shandong province, this article using DEA (Data Envelopment Analysis) method to research the agricultural economy productivity of 17 cities in Shandong province. The results showed that the mean overall agricultural production efficiency’s developing trends of Shandong province can be divided in three phases; different region’s overall efficiency, technical efficiency and scale efficiency had significant differences; western Shandong had clearly insufficient in agricultural extension and technological achievements, middle Shandong must improved the structure of agricultural production inputs. And in practice, should relied on technological progress and optimal combination of production factors to improve the efficiency of agricultural production.
