内容简介:

Influencers on social media platforms post sponsored content to capitalize their influences on audiences. Those sponsored content usually contains (third-party) shopping links on advertised products. Industry reports argue that such shopping links failed to attain high conversion rates and create little value for both influencers and the platform. We take advantage of an exogenous event — the blocking of all shopping links on sponsored content by a leading social media platform in China in August 2021 — to causally identify such effects on influencers and consumers. Using a difference-in-differences approach, we compare the changes in influencer and consumer behaviors before and after the event across organic and sponsored posts on the platform. We find that after the blocking, influencers wrote longer sponsored posts and wrote sponsored posts in a style with more commercial elements.  Consequently, consumers engagement to sponsored content decreased after the blocking. Such negative effect on consumer engagement is stronger among influencers with larger audiences. Our study is among the first to provide empirical analysis of the impacts of (third-party) shopping link on social media platforms.
