| 摘 要： | 采用FAO在线查询数据以及改进的RCA指数建立马尔科夫模型,计算预测2008年的理论状态概率,再与实际的状态概率进行对比分析。结果表明：我国水产品的实际竞争优势状态处于一种向中间收敛的趋势,即具有较强竞争优势及一般竞争优势的水产品在增多,而具有强竞争优势及较弱竞争优势的水产品在减少。分析了可能导致实际状态概率与理论状态概率差异的原因,提出如何在现有资源条件下提高水产品竞争优势的相关建议。

| Abstract: | The paper made a Markov model with the data of FAO and improved RCA,calculated the theoretical state probability of 2008,compared to the realistic probability and found that the actual status of competitive advantage has a trend of convergence.It also could saw that the number of very strong and general competitive advantage of aquatic products were increasing and strong and weak competitive advantage were reducing.It also analyzesd the reason of the difference.At last,it gave the suggestions for how to improve the competitive advantage of aqua-products on the condition of now available resources. |
