  Brief introduction:

  While prior literature mainly focuses on the effect of social media marketing on individual consumer behavior, we study the economic value of firm social media marketing at the firm level. Specifically, we quantify the sales effect of firm social media marketing from an integrated social commerce platform, and examine how such effect varies with firm characteristics. By a quasi-experimental design and using Propensity Score Matching (PSM) and Difference-in-Differences (DID) methods, we find that firm social media marketing significantly promotes sales at the firm level. Specifically, firms selling low-involvement products benefit more (with a sales elasticity of 27.89%) from social media marketing efforts, compared to those selling high-involvement products (a sales elasticity of 19.84%). Meanwhile, the sales effect of firm social media marketing increases over time. We also find that firm social media marketing with more followers and more blogpostings enhances firm sales more. Our results hold for various robustness checks, and we apply control function model to remove potential hidden bias in the matching process. Overall, our findings suggest that social media marketing plays an important role in firm marketing activities, and firms need suitable strategy to gain from their social media marketing efforts.
