摘要
文章针对区域国民经济发展的多属性,采用投影寻踪评价模型,用加速遗传算法寻找最佳投影方向,将多维属性指标转换为一维投影值。在此基础上,通过建立单属性指标的分类等级区间,给出区域国民经济发展水平分类的投影值区间,从而实现对区域国民经济发展水平的分类。应用表明,它是国民经济评价的一种计算过程简单、直观的新方法。
To the multiattribute of development of economy, the paper converts multidimensional economy indexes to projection value of single dimension by projection pursuit model which can find optimal proiection direction using accelerating genetic algorithm. Finding the grade range of each index and calculating the projection range it can classify development level of economy for the area. The application shows that PPM provides a new method which is intuitional and simple for the evaluation of national economy.
