AbstractOnline knowledge sharing (e.g., Quora, Zhihu, StackOverflow) has become a trending way for people to seek knowledge from each other on internet. Compared with traditional knowledge sharing organizations (e.g., schools, institutions), online knowledge sharing provides an open platform which allows knowledge to be shared and diffused in a bigger scale with a lower cost. Millions of people have contributed a huge amount of knowledge to those platforms in merely a few years and many online knowledge sharing platforms have been valued billions of US dollars. Despite the dramatic growth of online knowledge platforms, they are all facing an urging challenge: how to incentivize people to contribute high quality knowledge?
Our research taps into this challenge by studying knowledge sharing behavior on Zhihu.com, one of the largest online knowledge sharing platforms in China. By collecting a panel of 132,000 users’ shared knowledge (approximately 2 million answers on 1 million questions) since the first day of their registration, we investigate (1) how does the quality of shared knowledge evolve over time? (2) how is the quality of a user’s shared knowledge influenced by other users’ shared knowledge? (3) how is the quality of a user’s shared knowledge influenced by social interactions among other users?
Using a panel data model with individual user fixed effects, we find that in the first few days after a question is post online, a user contributes higher quality knowledge if other users have shared a good amount of knowledge, but afterwards as the amount of shared knowledge increases, he is likely to contribute low quality of knowledge. We also find that the quality of shared knowledge increases as the social interactions among other users increases.
