| Summary: | 碩士 === 國立中興大學 === 農業經濟學系 === 82 === In order to abound the supply of vegetables to stabilize market
prices and ensure farmers' profits, the government has
established the "Guarantee Fund of Summer Vegetables" and
conducted guaranteed price marketing program for selected
summer vegetables since 1976. The primary objective of this
research is to analyse the welfare effects of the summer
vegetable marketing program based on different guaranteed
prices and quantity under a disequilibrium market setting.
Chinese cabbage which is the leading crop in guaranteed
quantity and subsidy was chosen for empirical study. Consi-
dering the availability of the market program, only the Taipei
fruit and vegetable wholesale is included as the market scope
of this research. Primary findings from empirical results are
as follows: 1.The guranteed price marketing program is
effective controling the product source of Chinese cabbage by
the market. 2.The market price of Chinese cabbage during summer
period can'not adjust completely. While the speed of
adjustment on supply side is slower than does the demand side.
3.The price elasticities of supply and demand for Chinese
cabbage will be overestimated in absolute term based on an
equilibrium market model. 4.Social welfare would be better off
if the highest and the lowest prices in last five years were
excluded when esta- bilishing the guaranteed price for Chinese
cabbage. 5.The social welfare will increase when adding 10% of
the con- tracting quantity to the current system. 6.If
guaranteed price is set at the level of monthly average price
of the last five years, it will reduce the stability of market
price for Chinese cabbage.
