强势品牌广告竞争的溢出效应

Spillover effects of strong brands competition

本研究探讨同一品类两个强势品牌广告竞争对弱势品牌产生的影响,研究尝试将广告重复、广告长度作为操控广告竞争强度的具体手段,运用感知到的广告竞争水平来表示广告竞争强度。研究结果表明,同一品类两个品牌同时进行广告重复的水平不同,可以导致被试感知到的广告竞争水平有显著差异,广告重复次数越多,被试感知到的广告竞争强度越高,广告长度对感知到的广告竞争作用不显著。研究同时发现:随着两个强势品牌广告竞争强度的提高,消费者对弱势品牌的品牌态度降低,这表明强势品牌广告竞争对弱势品牌具有溢出效应。另外,研究还发现产品涉入度和产品属性相似性对强势品牌广告竞争的溢出效应具有调节作用,涉入度低的产品和属性相似性高的产品溢出效应更大。本研究丰富了溢出效应理论,增加了溢出效应类别,同时对同一品类内部的广告实践具有重要的指导意义。

Although there are many studies focusing on competitive advertising, brand advertising, category advertising, advertising clutter, and advertising interference, there has been little research focusing on strong brands competition. The extent literature focuses on Product Crisis Spillover Effect, Umbrella Branding Spillover Effect, Advertising Spillover Effect, and Corporate Social Responsibility Reputation Spillover Effect. However, what is the spillover effect for competition taking place among strong brands on weak brands？ What will happen to the weak brands when two strong brands competing in the same category？ Is it explained by the spillover effect theory？ And what is the mechanism？ These are a series of interesting questions that have both theoretical and practical value.A total of 855 college students（mean age = 22.6 years, SD = 3.4 years） participated in the experiments. First, advertising repetition and advertising length were used as the stimuli indicating competition strength, and perceived competition was used to represent competition strength. Then, the following focus question was investigated： will there be spillover effect on weak brands when two strong brands competing in the same category？ Finally, the moderating role of product involvement and product attribute similarity for the main effect was tested. Experimental methods were adopted in these studies and fictitious brands were used to test the research hypotheses. The results of the present study indicates that, advertising repetition is closely related to perceived competition, and the more repetitions of two brand advertisements, the higher the competition level perceived by the subjects is, which indicated that advertising repetition can be used as a specific means of operating the advertising competition. However, the advertisement length has no effect on the perceived competition. Strong brand advertising competition has a spillover effect on weak brands. With the increase in the competition strength of strong brand advertising, the spillover effect on weak brands has also increased accordingly. The degree of product involvement and similarity of product attributes have a moderating effect on the main effect, and the lower product involvement and the higher similarity of product attributes tended to produce the greater spillover effect. The current study enriches the existing spillover theory and discovered the spillover effect of strong brand advertising competition within the same category on weak brands for the first time. At the same time, the study found that the product involvement and product attribute similarities have a moderating effect on the spillover effect. The conclusions of the research can be used to guide advertising practice and brand owners and market managers in different market positions.
