Measuring Price and Quality Competition
提出一种利用比较判断法则将企业间序数比较转化为可靠价格与质量尺度的方法，并应用于家电行业八类产品中五家制造商和十五家子公司的竞争分析。
Portfolio management requires precise measures of price and quality competition across relevant lines. A methodology is proposed that uses the Law of Comparative Judgment to transform ordinal comparisons between firms into reliable price and quality scales. Results are presented for five broadline manufacturers and fifteen subsidiaries competing in eight product classes in major appliances. The scale values and subsequent interpretations are substantiated by two major trade studies commissioned by the appliance industry. Implications for integrating quality considerations into the strategic planning process are discussed.
