We examine how placement of geo‐targeted local news links on Google News affected local news consumption. Using a sample of news visits by 36,876 U.S. households before and after a Google News design change, we find that aggregation increased the level and share of local news consumed online. Magnitudes are modest: consumption of local news among heavy Google News users rose by 25% after the redesign, but from a low base. Geo‐targeting increased weekly consumption variety and reduced concentration among local outlets but did not raise overall consumption variety, suggesting that aggregators play a limited role in product discovery.

在线本地新闻：聚合器，地理位置定位和本地新闻市场*

我们研究了在Google新闻中按地理位置定位的本地新闻链接的放置如何影响本地新闻的消费。使用Google新闻设计变更前后36,876个美国家庭的新闻访问样本，我们发现汇总可以提高在线消费的本地新闻的水平和份额。幅度适中：重新设计后，沉重的Google新闻用户中本地新闻的消费量增加了25％，但基数较低。地理位置定位增加了每周的消费种类，降低了当地网点的集中度，但并未增加总体的消费种类，这表明聚集者在产品发现中的作用有限。
