利用VF实现县域经济综合实力评价系统的一个实证解析

摘要

县域经济综合实力评价系统,采用主成分分析法构建评价指标体系,运用计算机数据处理的定量结果得出定性结论.在整个系统的数据处理中,确定各指标的权数是关键的一步,用雅克比迭代法来求解权数是一个值得参考的方法.这里通过实例,简要介绍利用雅克比迭代法求解特征向量、特征值,实现县域经济综合实力评价计算机系统的要点.%County Comprehensive Economic Strength Evaluation System constructs the evaluation index system using principal component analysis and then reaches the qualitative conclusions utilizing quantitative results by computer data processing. During the entire data processing system, how to determine each index is the key step, and to solve the weighting Jacobian iteration method is worth considering. Through an actual example, this thesis makes a brief introduction to the characteristics of the computer system aiming to evaluate the comprehensive strength of county economy by using Jacobian to make out eigenvector and eigenvalue.
