在分析政府形象效能評價系統(tǒng)和信息置信度的基礎(chǔ)上，建立了基于信度函數(shù)的政府形象評價模型。運用該函數(shù)建模分析了政府形象評估中的理念識別系統(tǒng)、行為識別系統(tǒng)、視覺識別系統(tǒng)、環(huán)境識別系統(tǒng)以及個人識別系統(tǒng)等五大不確定性評價問題。經(jīng)過理論分析，該函數(shù)對政府形象的評估有較大的參考價值。此外，該函數(shù)也可以用于對其他類似復(fù)雜性系統(tǒng)的效能評估，具有普遍適用性。

Abstract Based on the analysis of evaluation system of the government image, an evaluation model is built based on the belief function of the government image. This model is used to analyzes five uncertain problems of the evaluation of government image, including mind identity system, behavior identity system, visual identity system, environment identity system, and personal identity system. Our analysis shows that the belief function can bring more valuable reference for valuating the government image.
