Abstract: Online review helpfulness has increasingly become a hot topic in recent years. However, existing researches fail to reach consistent conclusions on the direction and strength of the factors affecting review helpfulness. Combining empirical studies on the helpfulness of online reviews at home and abroad, our work builds a framework based on elaboration likelihood model and utilizes Meta-analysis to reanalyze 540 effect values of 138 independent studies. Our work explores the quantitative relationship between review helpfulness and its influencing factors from both review (central route) and reviewer (peripheral route) characteristics, and further explores the reasons for the heterogeneity through Meta-regression and finds some interesting insights. This study has great significance for academic research and e-commerce practice.

Key words: online review helpfulness, Meta-analysis, elaboration likelihood model, review characteristics, reviewer characteristics
