The Instagram Effect: Is Social Media Influencing Visitation to Public Lands?
研究结合俄勒冈州立公园的访问数据与Instagram的地理标记内容，发现Instagram仅对少数高用户参与度的公园访问量有正向关联，整体上无显著影响。
<h3>Abstract</h3> Public lands in the United States have recently experienced significant increases in visitation. Journalists and park managers suggest Instagram as a reason for the increase. We explore this issue in the Oregon State Park system by combining visitation data with park-specific georeferenced content and engagement indicators from Instagram. Using several empirical specifications, we show suggestive evidence that Instagram is not likely correlated to increased visitation everywhere, but only in a few locations generating high user participation within the app. We find no contemporary effect and a positive association with cumulative Instagram engagement indicators on visits at this subset of parks.
