Hot Spots and Blind Spots: Geographical Clusters of Firms and Innovation
构建演化模型，对比同一行业内热点集群与非热点集群的竞争企业，指出集群初期促进创新，但后期同质化文化抑制创新，使热点企业更易受环境冲击。
Hot spots are fast-growing geographic clusters of competing firms.Drawing on several literature streams, we develop an evolutionary model that contrasts hot spot and non-hot spot competitors within the same industry.Initially, economies of agglomeration, institutional forces, and managers' mental models create an innovative environment within the hot spot.Over time those same forces create a homogeneous macroculture that suppresses innovation, making hot spot competitors more susceptible than non-hot spot competitors to environmental jolts.
