企业年金是一种由企业主导、市场化运作的补充性养老金制度，旨在为职工提供额外的养老金收入，以缓解基本养老金的不足。

企业年金计划通常由企业自主制定，通过设立个人账户的方式，由企业和职工共同缴费，形成企业年金基金。基金按照市场化方式运作，实现保值增值。职工在退休或离开企业时可以领取个人账户余额。

企业年金的优势在于为企业提供了一种长期、稳定的养老金来源，同时也可以提高职工的忠诚度和归属感。此外，企业年金还可以作为一种激励机制，鼓励职工积极参与企业的发展。

然而，企业年金也存在一些问题。首先，由于企业年金涉及到长期的资金积累和投资运营，因此风险也相对较高。其次，企业年金的运作需要专业的投资机构和监管机构进行管理，成本较高。最后，由于不同企业的年金计划存在差异，因此也存在着不公平的问题。

总的来说，企业年金是一种有益的养老金制度，可以为职工提供额外的养老金收入，同时也为企业提供了一种长期、稳定的养老金来源。然而，也需要考虑到其存在的问题和风险。
