分析了近几年带鱼市场价格变动规律和带鱼消费的收入与价格弹性。研究表明:(1)产地市场的带鱼价格在一年内经历2～3个涨跌周期;(2)产地市场的带鱼价格在2007年有较大幅度的提高;(3)不同规格带鱼价格都有上扬趋势,规格350～500 g带鱼平均价格上升最快;(4)上海地区带鱼的需求收入弹性大于0而小于1。为了提高带鱼产业的经济效益,首先应提高捕捞网具的选择性,有效保护小规格带鱼;其次应对小规格带鱼实行市场禁入政策;第三,鼓励使用钓渔具捕捞大规格带鱼并给与适当补贴,对使用破坏性渔具捕捞小规格鱼类的渔船合理征收税费等;第四,应推进TAC制度、个人渔获配额制度和个人可转让配额制度,以有利于带鱼的均衡供应。
The changes of the price of the octopus market in recent years and the income and price elasticity of the octopus consumption are analyzed. The results show that: (1) The prices of octopus in the producing markets have experienced 2 ~ 3 cycles in one year; (2) The prices of octopus in origin markets have been greatly increased in 2007; (3) The prices of octopus with different specifications have The average price of 350 ~ 500 g hairtail rose fastest; (4) The demand income elasticity of hairtail in shanghai was greater than 0 and less than 1. In order to improve the economic benefits of the octopus industry, we should first increase the selectivity of fishing nets and effectively protect the small-sized octopus. Second, we should impose a market-forbidden policy on small-scale octopus. Third, encourage the use of fishing gear to catch large-scale octopus and give appropriate Subsidies and reasonable collection of taxes and fees on fishing vessels that use destructive fishing gear to catch small-sized fish; fourthly, the TAC system, individual fishing quota system and individual transferable quota system should be promoted to facilitate a balanced supply of hairtail.
