Research on Space Frame of Multidimensional Dynamic Industry International Competitiveness Evaluation

The paper solves the problem of industry international competitiveness classification estimate by the method of multidimensional dynamic space analysis, builds the industry international competitiveness evaluation indicator system, uses the principal components method to get several principal components as the estimate indicators´ characters. Then it builds multidimensional dynamic model based on the estimate indicators´ characters. All the on-call points are described as corresponding points in the space, and ascribed to a suitable competitiveness rating. At last, it uses the shrimp industry data as a demonstration, by using time weight, we get the nations´ shrimp industry international competitiveness, then we use the control grade difference to classify the 5 countries´ international competitive power of shrimp industry to 3 grades. The result indicates that the method is worth spreading.
