Haidilao (HDL) has achieved fairly economical success in recent years. This paper firstly conducts external and internal business environment analysis of HDL, and then identify not only HDL's strenghens to make it being successful but also its weakness. My results suggest HDL's human resources are its strenghen by using hypothesis testing, while limited sources of revenue and relatively high price setting are its weakness. Hence, HDL should make solutions actively to mitigate the impacts of the weakness. This papers shows that by cutting 2% price, HDL's revenue will increase 2.6%. Other theoretical analysises in this paper also indicate that HDL is supposed to constantly improve its consumers' dining experience. For implications, this paper suggests the inefficient for business operating single-profit business. Moreover, the company who charges more does not necessary lead to more revennue.
