Abstract
This study provides an overview of the food supply and demand situation to the year 2010 in Asia based on the System Dynamics model. The amount of food demand will exceed the amount of food supply in India and China by 2010 if the exchange rate at the year of 1994 is to be continued and capital investment and the ratio of laboring population change as hypothesized below. Capital Investment : Part of newly obtained GDP is applied for investment. Newly obtained in "t year" will be invest as a Gross Capital Formation in "t+1 year". The relation between GDP and Gross Capital Formation is calculated. The growth rate of GDP is applied for estimating Gross Capital Formation. The following figures are considered to maintain until the year of 2010 as for GDP : Japan (1.2 %), India (3.2 %), China (7.0 %), Indonesia (6.4 %), Korea (4.3 %), Malaysia (4.3 %), Myanmar (3.8 %), Philippines (6.4 %) Sri Lanka (3.8 %), Thailand (4.3 %) and Singapore (4.3 %) on the basis of each country's currency. The Ratio of laboring Population : It is expected that the amount of labor affects the future amount of industrial production in Japan and Asian countries. In Japan, the shortage of labor force is presumable because of the rapid growth of aged population, whereas young labor force is abundant in Asian countries. The following figures are considered to maintain until the year of 2010 : Japan (2.2 %), India (2.2 %), China (2.0%), Indonesia (2.4 %), Korea (2.3 %), Malaysia (2.8 %), Myanmar (2.2 %) Philippines (2.2 %), Sri Lanka (2.2 %), Thailand (2.5 %) and Singapore (0.6 %).
