(2) Whether in the case of “one-for-one” or “to”, the revenue distribution coefficient of the LSI always shows a trend that first increases with the increase in the adjusted level and then decreases. Namely, an optimal adjusted level maximizes the coefficient of participation in turnover. Adoption 1. In order to assess the impact of the tailor-made level of different customers on a turnover participation contract, as in the study by Liu et al. [7], it follows that the adjusted level is a variable, a type of distribution that is not safe, which is its distribution function and which is a probability density function. Since the adjusted level is a random variable and will change with different clients, we assume, with regard to Liu et al. [7], that this is subject to a certain distribution. PandaTip: This section aims to settle the consequences of the termination of this profit-fixing relationship.
