术语“单峰偏好”的详细信息

英译术语:

single-peakedness

汉语语境:

单峰偏好理论是由邓肯·布莱克提出的。一维条件下，个体为单峰偏好可以解决"投票悖论"。将单峰偏好分析从一维条件扩展到二维条件直至N维条件，探讨N维条件下单峰定理是否适用。

英语语境:

The theory of single-peakedness was put forward by Duncan Black. The paradox of voting will be solved if the individuals have single-peaked preferences over the alternatives in a one-dimensional condition which is an important hypothesis of the theorem.The analysis of single-peakedness is expanded from one-dimensional condition to n-dimensional space.The concept of single-peakedness in an n-dimensional space is studied.The paradox of voting can not be avoided in an over two-dimensional space even though the preferences of the individuals are single-peaked.

英译术语:

single-peak preference

汉语语境:

传统的生育意愿调查研究都以单峰偏好即人们只有一个最优生育偏好为假设忽视了生育意愿存在双峰偏好的可能，因而有可能对生育意愿做出错误的估计和预测。有关专家从理论上论证了生育意愿出现双峰偏好的原因以及在单峰偏好假设下生育意愿调查的偏误；利用Probit模型对问卷调查结果进行了分析，检验了生育意愿双峰偏好的存在性;结合理论与统计结果对“丁克”家庭、生育意愿的性别差异、独生子女与非独生子女问的生育意愿差别等问题作了新的分析，得到了一些有意义的结果；并从生育意愿双峰偏好的视角对生育率下降过程提出了一个新的可能性解释。

英语语境:

Traditionally studies on fertility desire have a hypothesis of single-peak preference, that is, people have only one optimal fertility preference, ignoring the existence of double-peak fertility preference that could lead to bias on estimation and projection of fertility preference. Experts theoretically demonstrate the occurrence of double-peak preference and the reasons for bias in fertility prefernece survey under the assumption of a single peak preference. A Probit model is uesed to analyze a survey results, testing the existence of double-peak fertility preference. Combining theory and statistical results, it gives a new analysis of the issues, such as "DINK" family, gender differences in fertility preference, and differences of fertility preference between only and non-only children. Finally a new explanation of the process of fertility decline has been proposed in the double-peak preference perspective.
