Abstract: In order to make grain yield stable and increase grain production in Shandong Province, influencing factors on grain yield were analyzed by gray correlation method using statistical data in Shandong Province from 1991 to 2010. The results showed that effective irrigation area was the strongest influencing factor on grain yield in Shandong Province, followed by grain yield per unit area, area of cultivated land, effective amount of agricultural fertilizer, total power of agricultural machinery, pesticide amount and rural electricity consumption. Finally, the suggestions including improving the effective irrigation area, stabilizing and improving grain yield per unit area and area of cultivated land were proposed to ensure the stable grain yield increase in Shandong Province.
