摘要

我们分析了知识密集型活动的增加对美国城市空间不平等的影响。我们利用预先确定的专利引用网络来了解当地的创新趋势。1990年至2010年间，专利增长每增加一个标准差，收入隔离就会增加0.65个基尼点，相当于收入隔离随时间变化的0.31个标准差。这种影响主要来自于居民的收入、职业和教育程度。当地对创新的冲击导致了知识密集型工作和居民的聚集，并被租金和便利设施的反应放大。(凝胶d31, o31, o33, o34, r23, r32)

Income Segregation and the Rise of the Knowledge Economy

We analyze the effect of an increase in knowledge-intensive activities on spatial inequality in US cities. We leverage a predetermined network of patent citations to instrument for local innovation trends. Between 1990 and 2010, a one-standard-deviation increase in patent growth increases income segregation by 0.65 Gini points, corresponding to 0.31 standard deviations of the over-time change in income segregation. This effect mainly arises from the sorting of residents by income, occupation, and education. Local shocks to innovation induce a clustering of knowledge-intensive jobs and residents, amplified by the response of rents and amenities. (JEL D31, O31, O33, O34, R23, R32)
