Research on the Influence Factors on the Crop Food Supply Price using Data Envelopment Analysis Method

摘要

The study aims to investigate the influence factors on the crop food supply price using the Data Envelopment Analysis (DEA) method. Crops are the basic food rations for urban and rural residents and occupy the most important position in the food consumption. The price of the crop food has important influence on the stable economic operation and even social stability in China; hence it is crucial to find out the fluctuation rules and formation mechanism of crop food supply price. However, there is very little work has been done to look into the relationship between different influence factors and the crop food supply price. As a result, this study proposes a new method based on the DEA to quantitatively investigate the influence factors on the crop food supply price. The inflation, seeded area, cost of production, yield per unit area and rice consumption level have been selected as the influence factors in this study. Empirical analysis using the historical data acquired from China Statistical Yearbook during 2005 to 2012 has been carried out to calculate the quantities of the five factors connected to the crop food price change. The analysis results show that the price of the crop food is influenced obviously by the yield per unit area; meanwhile the cost of production has a certain impact on the crop food price. Hence, useful solutions can be proposed to stabilize the crop food price.
