Embedding the theoretical discussion on the framework of evolutionary regional innovation systems (RIS), this book reveals the informal nature of the emerging RIS in China, within which interactive learning is organized on the basis of social networks. Furthermore, in a comparative study in the Pearl River Delta, China demonstrates that dirigiste governance in the initial industrialization phase leads to a more mature and developed RIS than does grassroots governance. The theoretical developments and empirical investigation presented in this book will grant readers a deeper understanding of the specific features of RIS within the transitional context of emerging economies.
