| 摘 要： | 选择投资型繁殖策略的雌性动物提高繁殖能力的关键是获得尽可能多的彩礼,增加对后代的投资,提高抚育子代的成活率。生物学理论认为雌性动物在交配行为的选择时,多次交配不具有进化优势,只有尽可能少的交配次数才是雌性动物的合理选择。从经济学角度看,雌性动物的多次交配和尽可能少的交配次数的交配行为都是符合其投资型繁殖策略的经济选择的,都能提高彩礼的获得量而提高繁育子代的遗传收益。

| Abstract: | The key for raising reproductive capacity of the female who chooses the investment reproductive strategy,is obtaining more nuptial gifts for increasing investment of fostering progeny and enhancing progeny survival rate.From the point of view of biological theory,female's few mating behavior is the rational choice while multiple mating behavior does not accord with evolutionary law.But from the economic point of view,whether multiple mating or few mating behavior conforms to economic choice of investment reproductive strategy and can gain more nuptial gifts for enhancing genetic revenue of breeding. |
