作者：
Highlights：
• This paper studies the competition effect of product recommendation networks.
• Three network attributes, centrality, connection, and scale are measured.
• Their impacts on market competition in a homogeneous product market are tested at the global-network level.
• A panel data of 320,981 package tour products was used to estimate the model.
• Empirical results confirm the effect of three attributes on market competition.
