拖网渔船成本收益分析——基于荣成、象山、北海的调查数据

摘要:
近年来,拖网渔船捕捞成本不断上升,经济效益受到影响,捕捞成本和收益成为渔民最为关心的问题。文章依据2018年荣成、象山和北海的调研数据,对3个海区拖网渔船的成本收益进行分析。结果显示:在成本结构方面,油、冰、水支出占比最大,其次是雇工支出;在收益结构方面,捕捞生产收入占了绝大部分比重;在经济效益方面,利润由高到低依次为象山、荣成和北海,但总体来看利润都较低;在盈亏平衡和敏感性分析中,荣成拖网渔船捕捞风险最高,而北海拖网渔船更容易受到市场波动的影响,规避市场风险的能力最弱。基于此,拖网渔业渔船通过渔业合作社集中购买柴油的方式,以及使用现代捕捞设备等途径来降低成本,提高捕捞效益。渔业相关部门应完善相应的补贴政策,同时也要重视对渔民捕捞技术的培训,提高产品附加值以及加强对渔业资源养护与管理。

Abstract:
In recent years,the fishing cost of trawlers has been increasing,and the economic benefits have been affected.The fishing cost and benefits have become the most concerned issues of fishermen.Based on the survey data of Rongcheng,Xiangshan and Beihai in 2018,this paper analyzed the cost-benefit of trawlers in the three sea areas.The results showed that: in terms of cost structure,oil,ice and water expenditure accounted for the largest proportion,followed by labor expenditure;in terms of income structure,fishing production income accounted for the majority of the proportion;in terms of economic benefits,the profits were Xiangshan,Rongcheng and Beihai in order,but in general,the profits were low;in the analysis of break even and sensitivity,Rongcheng trawler had the highest fishing risk,while Rongcheng trawler had the highest fishing risk.Trawlers in the North Sea were more vulnerable to market fluctuations,and their ability to avoid market risks was the weakest.Based on this,trawlers could reduce the cost and improve the fishing efficiency through the way of centralized purchase of diesel oil by fishery cooperatives and the use of modern fishing equipment.The relevant departments of fishery should perfect the corresponding subsidy policies,pay attention to the training of fishermen′s fishing technology,improve the added value of products and strengthen the conservation and management of fishery resources.
