摘要：Commercial rice imports have accounted for approximately 61%, food aid in rice accounted for about 2%, and domestic rice accounted for some 37% per annum of rice consumption in Ghana over the four years between 2000 and 2003. Compared to the 1990s, these figures show a gradual decline in the share of local rice production in the total quantities of rice consumed in the country. On the other hand, the proportion of food aid in rice consumed has remained relatively constant over the period, while the proportion of commercial imports has increased steadily. Using the Engel-Granger residual-based co-integration test, a market integration analysis was explored for imported rice and domestic rice which compared a central market for imported rice and five key rice producing centres in Ghana. In addition, the various policies that affected rice during the period were analysed. The results of the co-integration analysis suggest that there is no spatial market integration between the central market price of imported rice and prices in the local markets. This implies that the prices of imported rice in these local markets do not share common properties or behaviour with prevailing price trends in the central market, suggesting that markets for imported rice in Ghana are segmented, and domestic policies have generally not favoured local rice production
