| Abstract: | Based on the data from the Cost-benefit Data of Farm Produce and the China Agricultural Yearbook, this paper aims to examine
the spatial and temporal change characteristics of total grain production and its affecting factors. The results show that:
1) During 1980 to 2007, total grain production increased from 3.20 × 108 t to 5.02 × 108 t in China, with annual increasing rate of 1.68%. From the regional disparities, most of the regions present increasing trend
of total grain production except for several regions with higher level of economic development; 2) Grain sown area decreased
from 1.17 × 108 ha in 1980 to 1.06 × 108 ha in 2007, which has negative effect on total grain production; 3) The increase of grain yield per unit area caused by land
use intensity changes contributed to the increase of total grain yield greatly. However, as the land use intensity showed
that farmers pay more attention to labor-saving input but not yield-increasing input, the less enthusiasm of farmers in grain
production may become an important constraint on future grain production increase in China; 4) Based on the results, this
paper proposed different land management policies in different regions, for example, the government should protect cultivated
land, promote large scale production. As to the less developed regions, the government should pay more attention to agricultural
subsidies to promote farmers’ enthusiasm in grain production. |
