通过实验研究企业发帖策略（强调能力、社会责任或两者结合）与电子口碑评论效价（正面或负面）如何共同影响消费者的企业关联感知、声誉评价和购买意愿。
Abstract Purpose Consumers tend to form their perceptions about a company via two associations: corporate ability (CA) that centers on expertise in producing quality products and corporate social responsibility (CSR) that focuses on societal obligations. To date, investigations on the adoption of such association-based corporate communication strategies are yet to address the interactive and multi-source features of social media. Drawing theoretical insights from corporate associations and the warranting principle, the purpose of this paper is to fill the gap and examine the joint effect of association-based corporate posting strategy and corresponding electronic word-of-mouth (eWOM) comment valence on social media. Design/methodology/approach A three (corporate posting strategy: CSR vs CA vs hybrid (CSR + CA)) by two (eWOM comment valence: positive vs negative) between-subjects experiment (n=193) was conducted. Findings The effect of corporate posting strategy on consumers' CSR associations was found to be significant only when eWOM comment valence was positive. Significant main effects of both posting strategy and eWOM comment valence were found on CA associations, perceived corporate reputation, and purchase intention. Originality/value This study extends the theoretical framework of corporate associations to the interactive context on social media and provides empirical evidence for the effectiveness of association-based posting strategies when they are jointly presented with eWOM comments at different valence levels. Findings of this study also provide implications for business and communication professionals to communicate with consumers on social media more effectively.
