Abstract: Non-Grain Production is verycommon to see in many areas in China, which threatens food security. To understand the spatio-temporal characteristics of NGP is helpful in mitigating it. This study has applied a new approach to measure the NGP rate. Results show that, the NGP rate reached the peak of 1.49 in 2003 across the 20 selected years. Moreover, the NGP rate was revealed to be higher in the north and the east compared to the south and the west. Additionally, the NGP rate is shown to move from north to south with a total of 68.78 km whenapplying the centroid migration model. The patterns of NGP are shown usingspatial heterogeneity: the high-high agglomeration pattern was revealed mainly in the north, while there are less provinces of this pattern as time goes by. In addition, the Theil index of the NGP rate indicates that the equity of NGP remains at a low level in the first ten years and getslarger and larger in the later ten years.
