Study on establishment of appraisal index system for food service industry's pursuit of quantitative graded management by Delphi method

目的建立餐饮业量化分级管理成效评价指标体系。方法应用特尔菲法（Delphi）设计，确定成效评价指标。结果通过咨询专家确立2级综合成效评价指标。评价指标的整体重要性赋值为4．00，其中1级指标的重要性赋值为3．89，2级指标为4．02，满分比达60％以上的指标占40．9％，最高达98．8％；专家对各项指标，意见的变异系数均在0．06-0．45范围内；1、2级指标及总的协调系数分别为0．713，0．429，0．423，经皮尔逊X^2R检验差异均有统计学意义；3个1级指标的权重系数分别为0．406，0．348和0．246。结论建立的成效评价指标包括3项1级指标和19项2级指标，可以较好地评价餐饮业推行量化分级管理所取得的成效，具有较高的信度。

Objective To establish appraisal index system for food service industry＇s pursuit of quantitative graded management. Methods Effect - evaluating indexes were designed and established by using the method of Delphi. Results Two levels of effect - evaluating index for food service industry＇ s pursuit of quantitative graded managemen were established by adopting the advice of specialists.
