While prawns are produced domestically, most prawns currently consumed in Australia are imported from Asia. Local producers are concerned that these imports are depressing prices for their product, and future growth in imports due to increased global supplies would reduce their viability. We examined the price integration of prawn products within the Australian market using the autoregressive distributed lag (ARDL) bounds testing method. A Dynamic Inverse Almost Ideal Demand System (IAIDS) was employed to derive own- and cross-price flexibilities and scale flexibilities for the three prawn categories to determine whether the supply of one prawn product had an impact on the price of the other prawn products. The results suggest there is no price integration between domestically produced prawns (wild-caught and aquaculture) and imported prawns, but strong price integration exists between domestically produced prawns. The findings of the demand analysis confirm this result.

澳大利亚对虾的市场整合和需求

虽然虾是在国内生产的，但目前在澳大利亚消费的大部分虾都是从亚洲进口的。当地生产商担心，这些进口产品正在压低其产品的价格，而由于全球供应增加而导致的未来进口增长将降低其生存能力。我们使用自回归分布滞后 (ARDL) 边界测试方法检查了澳大利亚市场内对虾产品的价格整合。动态逆几乎理想需求系统 (IAIDS) 用于推导三种虾类的自有和交叉价格灵活性以及规模灵活性，以确定一种虾产品的供应是否对其他虾产品的价格产生影响。结果表明，国产对虾（野生捕捞和水产养殖）和进口对虾之间没有价格整合，但国产虾之间存在很强的价格整合。需求分析的结果证实了这一结果。
