Urban Agglomeration and Firm Innovation: Evidence from Asia
利用亚洲城市边界一致测度的新数据和企业级数据，研究发现企业创新空间分布高度集中，大城市企业更可能推出产品/工艺创新并开展研发，且高质量大学和工程系的存在与企业创新正相关。
Abstract This paper examines the relationship between urban agglomeration and firm innovation using a recently developed dataset that consistently measures city boundaries across Asia together with geo-referenced firm-level data. It finds that the spatial distribution of innovation by firms is highly concentrated within countries. Further, firms in larger cities have substantially higher propensities to introduce product and process innovations and to undertake R&D activities, a result that holds for subgroups of countries and even when the largest cities are excluded from the analysis. Finally, the presence of high-quality universities and highly ranked engineering departments in cities is positively associated with firm innovation, lending support to the idea that the accumulation of human capital locally is a key channel through which urban agglomeration affects innovation.
