透過本研究可瞭解產業專家受查企業是否能提升已出售商品成本與存貨淨變現價值變動數資訊之價值攸關性，並提出實務上之建議，以期能提供給企業及後續研究者之參考。 This research is to examine whether or not the value relevance of cost of goods sold and loss on inventory changed in the companies audited by industry specialist, after the release of New SFAS No.10, comparing to the companies audited by non-industry specialist.
Up to 7,390 valid samples was selected from Taiwanese listed companies dated from 2009 to 2013 for Hypothesis Analysis. Only samples with completed financial information can be included. The research adopts Ohlson (1995) Valuation Model and analyzed by multiple linear regression.
The result shows that after the New SFAS No.10 issued the value relevance of cost of goods sold changed considerably in the company audited by non-industry specialist. The phenomena imply financial report users have concerns on the audit quality of non-industry specialist. Therefore, the value relevance of cost of goods sold plummeted considerably in the companies audited by non-industry specialist.
After the amendment of SFAS No.10, the value relevance of net realizable value did not reach to a significant level in the companies audited by both industry specialist and non-industry specialist audit companies. We assume the value relevance of net realizable value is not the key indicators for financial users to evaluate the future profitability and to make investment strategy. Since the release of New SFAS No.10, it makes it difficult for finance users to read and understand the financial reports. Therefore, the value relevance of net realizable value of companies audited by industry specialist and non-industry specialist did not show any significant level.
Through this research, we can realize whether both the value relevance of cost of goods sold and loss on inventory can be raised up in the companies audited by industry specialist. After that, feasible recommendation can be provided and for the further research.
