Acta Non Verba? The Role of Customer Participation and Word of Mouth in the Relationship Between Service Firms’ Customer Satisfaction and Sales Performance
研究发现，满意的顾客不一定重复购买，而口碑和顾客参与（提供建设性反馈）是连接满意度与销售的关键行为，其中顾客参与对未来销售的影响至少与口碑同等重要。
Evidence has shown that satisfied customers do not necessarily buy more of a company’s products and services, thus spurring researchers to look for a missing link between customer satisfaction and purchase behavior. Word of mouth (WOM) has been advocated as the elusive missing link and as a key indicator of customer-firm relationship strength. Yet, WOM is only one type of customer voluntary performance (CVP). In this study, a second type of CVP, namely customer participation (i.e., customers’ willingness to provide the firm with constructive feedback and suggestions), is argued to be crucial to ensure that a satisfied customer repurchases. The authors develop and test a model that predicts that satisfied customers repurchase when they become productive resources through two spontaneous and cooperative customer behaviors: WOM and participation. The empirical findings support the predictions, thus complementing and extending previous research. This research suggests that while WOM has been heralded as an important factor in firm growth, another factor that is at least equally if not more important to future sales is customer participation.
