English to Chinese Bus/Financial Investment / Securities

Most of the firms say in their proxies that in arriving at compensation agreements they use comparisons with one another. This suggests that compensation rises in something like lockstep. It also makes the economic rationale of chief executives as a group hard to fathom.
大多数公司在委托书中声明，自己在达成薪酬协议时，与其它公司作了比较。这表明薪酬就像步伐一致：你涨我也涨（？？）。作为一个群体的首席执行官其薪酬合理性也就很难彻底了解。
