“Plowback ratio”犁回率，也被称为留存率或收益保留率，犁回率是一种衡量方法，它关注的是股息分配给投资者后剩余的收益。由于该比率关注的是支付股息后剩余的利润，这有助于公司确定这些收益中能有多少投资或重新投入与公司相关的增长项目。企业主将密切关注这类留存率，作为衡量公司创收成功与否以及减少生产过程中浪费的有效性的一种手段。

The plowback ratio is a fundamental analysis ratio that measures how much earnings are retained after dividends are paid out. It is most often referred to as the retention ratio. The opposite metric, measuring how much in dividends are paid out as a percentage of earnings, is known as the payout ratio.

犁回率的计算公式为：

犁回率=（净收入Net Income—股利Dividends）/净收入Net Income

也可为：

犁回率=1—每股股利Dividends per Share/每股利润Earnings per Share

一般情况下，高犁回率表示管理层对公司的未来比较看好，认为公司将会实现高速发展，商业环境较好，而低犁回率则表示管理层对于公司的未来发展持小心、谨慎的态度。

以下为相关双语示例：

Use of the plowback ratio is most useful when comparing companies within the same industry. Different markets require different utilization of profits. For example, it is not uncommon for technology companies to have a plowback ratio of 1 (that is, 100%). This indicates that no dividends are issued, and all profits are retained for business growth.

在比较同一行业内的公司时，使用犁回率最有用。 不同的市场需要利用的利润不同。 例如，技术公司的犁回率通常为1（即100％），这种情况并不少见。 这表明该公司未分配股息，所有利润均予以保留，用于发展业务。
