【摘要】：大部分综合评价研究只解决了评价结果的排序问题,无法具体给出哪些因素才是影响具体评价对象特定评价结果的关键因素.次约束综合评价模型开拓了萃取影响评价对象关键因素的思路,但现有次约束研究的不足也很明显,将1个指标数据替换为最差值0,即去掉了这个指标的贡献后的评价得分反而可能会高于该指标得分不为0时的得分,这就是"完整指标体系"的评价得分反而小于"一个或几个指标对得分的贡献被去掉后"的评价得分的不合理现象.文章的创新与特色一是通过保持有n个指标的完整指标体系与n-1个指标的指标体系前后两次评价中指标的权重不变,来改进现有的次约束模型变权重的做法,改正"完整指标体系"的评价得分反而小于"一个或几个指标对得分的贡献被去掉后"的评价得分这种不合理现象.二是通过改进评价标准,在评价不同对象并萃取其优势和劣势因素时,将1个指标得分变为0前、后评价得分的排序是否变化的标准,改进为比较评价得分变化量大小的标准,避免了因前、后两次评价得分排序的序关系不变而导致的无法萃取优势或劣势因素的弊端.三是通过比较将1个指标得分变为0前、后两次评价得分变化量的大小,萃取出影响副省级城市经济社会发展的关键因素、优势和劣势因素.
[Abstract]:Most of the comprehensive evaluation studies only solve the problem of ranking the evaluation results, and can not give the specific factors that affect the specific evaluation results of the specific evaluation object. The sub-constraint comprehensive evaluation model opens up the idea of the key factors influencing the evaluation object of extraction, but the deficiency of the existing sub-constraint research is also obvious. Replace one indicator data with the lowest value 0, that is, if the contribution of the indicator is removed, the evaluation score may instead be higher than the score when the indicator score is not zero. This is the unreasonable phenomenon that the evaluation score of "complete index system" is less than that of "one or more indexes' contribution to score is removed". The innovation and characteristic of this paper is to improve the existing sub-constraint model by keeping the weights of the indexes in the index system with n indexes and the index system of n-1 indexes unchanged before and after the evaluation. The evaluation score of "complete index system" is less than that of "one or more indexes' contribution to score is removed". Second, by improving the evaluation criteria, when evaluating different objects and extracting their advantages and disadvantages, the standard of whether the ranking of the scores of one index is changed before and after the index is turned into zero is improved to the standard of comparing the magnitude of the change of the score. It avoids the disadvantage of unextractable advantages and disadvantages caused by the unchanging order relation of the former and the latter two evaluation scores. Thirdly, the key factors, advantages and disadvantages of influencing the economic and social development of sub-provincial cities were extracted by comparing the change of score of one index to zero before and two times after evaluation.
