ABSORPTIVE CAPACITY, KNOWLEDGE FLOWS, AND INNOVATION IN U.S. METROPOLITAN AREAS
研究了美国106个大都市区吸收外部知识的能力对创新生产率的影响，发现吸收能力有显著正向作用，并识别了塑造该能力的本地条件。
ABSTRACT High growth and progressive regions possess a culture that promotes innovation. Innovation depends on a region's ability to use its own existing knowledge and knowledge generated elsewhere. This paper demonstrates the importance of the ability to absorb external knowledge in explaining innovation productivity for 106 U.S. metropolitan areas. Using a spatial interaction model of patent citation flows with origin and destination dependence, the destination fixed‐effects coefficients provides a measure of a region's absorptive capacity. We identify local conditions that shape a region's absorptive capacity and demonstrate it has a positive and significant impact on innovation productivity.
