Two industrial challenges of uncertainty and interoperability arose as the new forms of industries structure have emerged. Network theories are systematically reviewed in three streams of network structure, network strategy and network evolution in order to find out the current theories' contribution on those two challenging issues, which include supply chain management (SCM), business network (BN), global manufacturing virtual networks (GMVN), strategic alliance (SA), open innovation (OI), industry cluster and industrial organization (IO). Furthermore, this study also explores their theoretical relationships with business ecosystem in order to highlight the research value and gap of business ecosystem, with a novel framework of 6Cs: construct, configuration, context, capability, change, co-operation.
