Shaping the effects of related and unrelated variety on innovation

Shaping the effects of related and unrelated variety on innovation

Artigo completo:

The aim of this paper is to investigate the impact of related and unrelated variety on innovation considering regional heterogeneity across locations. The literature regarding innovation and relatedness presents empirical evidence of the effects of related and unrelated variety on innovation but it demands further clarification, and this paper sheds light on these relations by looking at specific macro-regions. The empirical analysis uses a regional knowledge production function with panel data of Brazilian micro-regions between 2002 and 2017. Related and unrelated variety entropy measures are calculated using employee data. Utility models and patents are used as proxies for incremental and radical innovations, respectively. Our results show that related variety is associated with both measures of innovations while unrelated variety has stronger effects on radical innovation. Furthermore, heterogeneity across regions affect the relation between relatedness and innovation.
