本文提出以虚拟单位产量作为比较与评价水产养殖经济效果的一种方法,给出了量化公式。公式中,充分考虑了品牌价值而不只是价值,土地占用而不只是养殖水面的使用,生产时间的占用而不只是1“年”等重要因子。其中,土地的占用采用平均存鱼量与生产周期的积的比例方式作为分摊依据,虚拟产量以剖分后的价值比例系数折算。 In this paper, a method to compare and evaluate the economic effects of aquaculture is proposed based on the production of virtual units, and the quantitative formula is given. Formulas, taking full account of the brand value rather than just value, land occupation rather than just the use of aquaculture water, production time rather than just 1 “year” and other important factors. Among them, the occupation of land uses the ratio of the average amount of fish stored and the product of the production cycle as the basis for assessment, and the virtual production is converted into the proportionate value after the division.
