According to corporate marketing practice, we separately study three most-commonly-used incentive strategies, namely two price promotion types and one rebate type: the first type is the award-type price promotion strategy (referred to as the reward-type promotion), which is the reduced price of a specific percentage or amount given by manufacturers to distributors on specific products in a specified period; the second type is the threat-type price promotion strategy (referred to as the threat type promotion), which is the increased price of a specific percentage or amount notified by manufacturers to distributors in advance on specific products after a specified period, and which is also the original price that will be adopted when an order is placed before a speci- fied period; the third type is the “rebate strategy”, which means the order rebate of a certain percentage is given by the manufacturers to specified distributors on the specified products ordered by the distributors in a specified period after the manufacturers set a task quota for specified distributors and the distributors finish this task. In general, manufacturers will carry out the strategy of rebate percentage linked to task, namely, set up different task levels responding to different rebate percentages or amounts. The rebate percentage will be higher if more tasks are finished. Meanwhile, this rebate strategy will generally cover most of distributors.
