Innovation strategy choices in the urban economy
分析了企业创新战略如何受城市密度、多样性和国际连通性的影响，利用挪威数据发现首都企业创新参与度低但投入强度高，并展示了序列回归方法与传统估计的差异。
This paper analyses how the innovation strategies of individual firms reflect the density, diversity and international connectivity of their urban locations. It makes three contributions. Theoretically, it argues that observed strategies reflect a series of inter-related choices, and that each may be influenced differently by the knowledge dynamics of firms’ locations. Empirically, it uses Norwegian Community Innovation Survey data to demonstrate how firms in the Capital are less inclined to engage in innovation activities, but also more likely to commit strongly once engaged, than are comparable firms located elsewhere. Methodologically, it illustrates how the results of sequential regressions on inter-related strategy choices differ from those obtained using a more conventional estimation strategy. Implications for innovation policy and research are drawn.
