摘要： 社会和学术界普遍期待以法律手段解决年龄歧视，但这一主张存在众多问题。年龄歧视的性质与其说是身份性歧视，不如说是市场中的信息筛选规则。从平等保护的角度看，生命周期理论提示我们，老龄人并没有受到不公平对待，因为公平必须以整个生命周期而非某个年龄片段进行比较。同时，老龄人作为一个整体也并非就业市场上的弱势群体。从手段目的合理性的角度看，以法律手段反对年龄歧视可能只会对少部分老龄精英具有正面作用，对于处于弱势地位的某些老龄人来说，反而可能具有负面作用。我国目前不应当将年龄歧视纳入法律反歧视的范围。

Abstract: Chinese society and academia has proposed to enact its age discrimination law for a long time. However, this proposal has several problems. From the perspective of the essence of the age discrimination, it is more of a proxy for information selecting than a matter of discrimination. From the perspective of equal protection, the life-cycle model would prove that the elderly are not treated unequally by the society and the elderly are not a group of disadvantaged group. From the perspective of means-end rationality, the age discrimination law would not have any positive affect on reducing the unemployment of the elderly. Based on these reasons, China should not enact its age discrimination law.
