To review the literature could always help us to find the limitation of past studies. This paper offers a literature review concerned with audit opinion from foreign studies to Chinese studies.

The stakeholders value audit opinion and they have different demands of audit opinion to meet their demand. For example, tax department needs the information of revenue and profit to collect tax, creditors need to know the exact number of assets to guarantee their loans, and investors prefer to learn the profitability of companies from financial statements. The article provides a holistic view of audit opinion to give other researchers an implication on which part of audit opinion needs to be studied further.
