本研究利用成本邊界模型(Cost frontier model)與實際調查超集約養蝦戶的生產費用相關數據，估算出HACCP體系之相對生產成本，進而利用該估計結果，推算出在不同利潤考量下的養殖存活率。例如：在未實施HACCP體系時，活存率需達到25.38%才能達到損益平衡；若實施HACCP體系時，因成本增加，活存率要提高到33.75%才能達到損益平衡。當未採行HACCP體系時，活存率達25.38%其利潤為0；若採行HACCP體系則活存率會從25.38%提高到45.38%，有20%的利潤。

The cost frontier model and the production cost data of super-intensive shrimp farms are used to estimate the production cost frontier function of shrimp farms. The estimated cost function was then used to calculate the production cost of shrimp farms with or without implementing HACCP. The survival rate was also calculated for different profitabilities. Our research findings suggest that the survival rate should achieve 25.38% for shrimp farm to be at break even point; while implementing HACCP, the survival rate should increase to 33.75% to be at break even situation. Since in general, the survival rate of farms adopting HACCP is 20% higher than the firms without HACCP. Therefore, the firm with HACCP will enjoy a 20% profitability when the other is struggle from breakeven.
