前两天看到一个讨论贴，里面有哥们提到这个东西。我也能查出来怎么算，问题是有没有benchmark可以衡量呢？

There is benchmark for different type of business, what business benchmark are you after?

零售业和餐饮业。不知道哪里可以找到这些东东的benchmark呢？

There are benchmarks for broad industry and fine industry, you may want to specify the type of retail/food service you want to know about. then i can give you some figures.
Most accountant will have a rough idea of the industry benchmark.
