当代年轻人热衷于“吸猫、撸狗”，他们把宠物当作孩子，对宠物的依恋程度很高。已有对宠物依恋的研究表明宠物依恋会对繁殖感产生影响，宠物与孩子有很多的相似之处，因此宠物依恋可能会影响宠物主人的生育行为。有研究指出宠物会起到替代作用，抑制主人的生育意愿；另一些研究则指出宠物会激发主人的生育意愿。不同的结论可能是由于宠物主人的主观社会阶层不同导致的。进化心理学把生育意愿作为生命史理论的一部分进行研究，为本研究提供了解释生育意愿的理论根据。本研究探索了宠物依恋对不同群体年轻人的生育意愿的不同影响，并试图探索这其中的作用机制。

本研究通过实证的方法，探讨宠物依恋是否会影响青年的生育意愿。研究一采用实验法，通过宠物与人亲密互动和宠物给人带来麻烦的材料来启动被试不同水平的宠物依恋感知，进而考察宠物依恋对生育意愿的影响。研究一探讨了宠物依恋和生育意愿的关系，对孩子的偏爱程度在其中起中介作用；在此基础上，研究二进一步验证宠物依恋对生育意愿的影响，同时考察宠物依恋影响生育意愿的边界条件。研究二通过问卷法，考察宠物主人的宠物依恋程度和生育意愿水平，以及主观社会阶层的调节作用。

结果表明，主观社会阶层的调节作用成立。主观社会阶层高的个体，对宠物依恋的变化更为敏感，而主观社会阶层低的个体对宠物依恋的变化不敏感。具体表现为，对于主观社会阶层高的个体，当宠物依恋程度低时，他们会有较高的生育意愿，当宠物依恋程度高时，宠物对孩子的替代作用会凸显出来，他们的生育意愿会逐渐降低；而对于社会阶层低的个体来讲，宠物依恋对生育意愿的影响不显著，因此宠物依恋程度的高低对生育意愿的影响无差异。

Contemporary young people are keen on “keep pets”, they regard the pet as the child, their pet attachment degree is very high. Pet attachment has been shown to have an effect on feelings of procreation, and there are many similarities between pets and children, so pet attachment may influence the reproductive behavior of pet owners. Some studies have suggested that pets can act as a surrogate, dampening owners'desire to procreate; others have suggested that pets can stimulate owners'desire to procreate. Different conclusions may be due to the subjective social class of pet owners. Evolutionary psychology studies fertility desire as a part of the theory of life history, which provides a theoretical basis to explain fertility desire. This study explored the different effects of pet attachment on the reproductive intentions of different groups of young people, and tried to explore the mechanism of this effect.

The purpose of this study is to explore whether pet attachment has an effect on the fertility desire of young people. In the first study, the effects of pet attachment on procreation intention were investigated by using pet-human interaction and pet troublesome materials to activate different levels of pet attachment perception. The first study explored the relationship between pet attachment and procreation intention, and the second study examined the effect of pet attachment on procreation intention, as well as the moderating effect of subjective social class. In Study 2, the degree of pet attachment and the level of procreation intention, as well as the moderating effect of subjective social stratum were investigated by questionnaire.

The results show that the moderating effect of subjective socio-economic status is established. Individuals with high subjective socioeconomic status are more sensitive to the change of pet attachment, while individuals with low subjective social class are less sensitive to the change of pet attachment. For the individuals with high subjective social class, when the pet attachment degree is low, they wil Contemporary Young people are keen on "sucking the cat, stroking the dog" , they regard the pet as the child, the attachment degree to the pet is very high.

For the individuals with high subjective social class, when the pet attachment degree is low, they will have higher fertility desire, and when the pet attachment degree is high, the substitution effect of the pet to the child will be prominent, however, for individuals with low socioeconomic status, the effect of pet attachment on fertility intention was not significant, so the degree of pet attachment had no significant effect on fertility intention.l have higher fertility desire, and when the pet attachment degree is high, the substitution effect of the pet to the child will be prominent, however, for individuals with low socioeconomic status, the effect of pet attachment on fertility intention was not significant, so the degree of pet attachment had no significant effect on fertility intention.
