How Often Versus How Long
研究了客户接触频率和关系持续时间如何影响客户报告的关系强度，发现关系持续时间会调节接触频率的效果：短期关系中频率提升关系强度，长期关系中则无影响。
This study investigates the effects of customer contact frequency and relationship duration on customer-reported relationship strength (CRRS). We embed our analysis of these two relationship-quantity variables within a larger model that considers the effects of relationship-quality variables—commitment, trust and satisfaction—on CRRS. We additionally control for customer demographics and service type. Using a fully national sample of 591 service consumers, we find that both contact frequency and relationship duration have a positive effect on CRRS, and that duration moderates the effect of frequency. Specifically, we observe a relationship-maturity effect: for shorter-duration relationships, contact frequency enhances CRRS, but for longer-duration relationships, contact frequency has no effect on CRRS. Furthermore, employing an iso-contact analysis, we find that for relationships with about the same number of total contacts, those with longer duration are perceived to be stronger, while those with greater contact frequency are not.
