To solve the problems of the optimal rebate standard ofmanufacturers to sealers and the
lowest sales volume corresponding to the standard to stimulate dealers efforts and gainmore profits, a
gamemodelbetween the relationship of amanufacturer and its sealerswas set up and analyzed. The
research shows that the optimal rebate of amanufacturer to its sealers fallswith the increase of rival
dealers productprice, and that the lowestsales volume demanded by the optimal rebate increaseswith
the increases of total socialdemand for a productand productprice given by a rivalmanufacturer to its
sealers, fallswith the raise ofproductprice given themanufacturer to itselfsealers, and hasno relation
to themarketprice of the product.
