摘　　要：进化心理学认为性别比例失衡会影响物种择偶难度,在中国性别比例处于失衡状态,新生儿中男女比例甚至达到了120:100。性别比例会对中国人的择偶行为产生什么样的影响还不清楚。本研究通过对男性偏多和女性偏多的学生在择偶过程中的消费行为的调查发现,在男性偏多情况下男性会花费更多金钱请女性吃饭,而在女性偏多情况下女性感知到找男朋友更加困难并且在将来更加偏向于选择工作而不是家庭。研究表明性别比例失衡的确会对人在择偶过程中的消费行为产生影响,同时也对其理论意义和实践价值进行了探讨。According to evolutionary psychology, sexratio in a population is an important factor in determining mating behavior inanimals. We propose that sex ratio also has pervasive effects on humans. The sex ratio in China is in a stateof imbalance, and sex ratio of baby even reaches 120:100. But effects of sex ratio to matingbehavior of Chinese were not clear. The study examines consumer behavior of mating in male-bias andfemale-bias and gets the effects. Findings show that male-bias leads men to spend more money on inviting women to have ameal. Female-bias leads women to perceive more difficulties in finding another half and will choose work in thefuture but not family. Research shows that sex ratio indeed influences consumer behavior of mating. We also probe the theoretical significance and practicalvalue of sex ratio.
