How do national factors intersect in network formation in different emerging sectors? Scholars have focused on these regarding networking phenomena: the effects of national and sectoral factors. In spite of their theoretical contributions, attempts have been neglected in identifying and/or linking the factors from both national and sectoral innovation systems within the networks. This paper examines the cross-country differences within a sector, and the cross-sectoral differences within a country, as the consequences of sectoral–national intersections.

Understanding the role of government policies in promoting the introduction of renewable technologies can help to catalyze the transition toward a more sustainable energy system. The literature on technological transitions using a multi-level perspective suggests that the co-evolution of the niche market (the new technology) and the complementary regime may have an important role to play in shaping this transition. This paper provides a quantitative analysis of the interactions between different types of solar photovoltaic (PV) networks at the niche level, the complementary semiconductor sector at the complementary regime level, and the solar PV policies in 14 different countries.
