基于灰色定权聚类模型的罗非鱼国内市场潜力分析

The analysis on tilapia domestic market potential based on gray fixed weight clustering model

中国罗非鱼产业长期以来受到国际市场的限制,发展水平低,开拓国内市场是其改变现状的必然途径。论文利用2012年中国各省(区、市)的经济发展数据和专家咨询数据,构建灰色定权聚类模型,从而分析各地区罗非鱼的市场潜力,所采用的评价指标包括罗非鱼产品的价格、当地消费者的收入水平、消费者偏好等。模型回归结果和实地调研结果基本一致,具有较强的现实参考意义。定权聚类模型分析的结果显示,市场发展潜力较大的地区包括重庆、四川、贵州、辽宁、江西等地,发展潜力一般的地区包括山西、内蒙古、吉林、黑龙江、安徽等地,发展潜力较小的包括北京、天津、河北、江苏、福建等地。

In China, the tilapia industry develops slowly for a long time, which is limited by the international market. The only way to change the status is exploring the domestic market. Based on the economic development data and expert consulting data of provinces in 2012, this paper built a gray fixed weight clustering model to analyze the market potential of tilapia of the various regions. The evaluation indexes included price of tilapia products, income level of local consumers, consumer preferences, etc.. The regression results and the survey results are consistent, which makes this paper a strong practical value. Through the analysis of the fixed weight clustering model, we found that regions which have a larger regional market potential include Liaoning, Chongqing, Sichuan, Guizhou and Jiangxi, etc.. The regions which have a medium potential include Shanxi, Inner Mongolia, Jilin, Heilongjiang and Anhui, etc.. And the regions which i have a smaller developing potential include Beijing, Tianjin, Hebei, Jiangsu and Fujian, etc..
