This paper discusses the technological upgrading of China in photovoltaics technology. It explores the patterns of innovation and network-embeddedness and their impact on economic performance at the firm level. Identifying the main innovators over 1995-2014 with patent and market-share indicators, the landscape of their activities is inspected through two hierarchical cluster analyses in parallel: First, against the quantity, quality and diversity of patents, and second, against global-integration, component-size and position in technological knowledge networks. The resulting clusters are cross-related to understand their interrelations with age, size, turnover and productivity of actors. The multivariate analysis of variance shows a significant relationship between innovation-network concurrency and the age, turnover and productivity. Globalintegration in small-world networks is significantly related with economic performance. Quality of innovation shows higher importance than quantity and diversity. While specialization in hightech fields has positive impact on turnover, production-oriented firms with low-tech focus have higher productivity.
