Purpose The purpose of this study is to identify the types and features of business relationship when the value co-creation phenomenon is extended to an early stage of the value chain, in which technological innovation is essential, in a high-tech business-to-business (B2B) market. Design/methodology/approach The methodology of building a theory from a case study is adopted in this study to propose an early-stage value co-creation network. Qualitative data are coded on the basis of grounded theory coding after collecting the triangulation data from multiple sources. Findings In a high-tech B2B market, three types of business relationships (supplier–customer mutual, supplier-centric and network-based business relationships) co-create values at an early stage of the value chain. Intellectual resource, efficiency resource and supplier-centric business relationships are uniquely found in this stage. Research limitations/implications This study provides new insight suggesting that the notion of value co-creation can be extended to early stages of the value chain in a high-tech B2B market. In addition, this research identifies vital business relationships and how these relationships develop successfully at an early-stage value co-creation network in a high-tech B2B market. Practical implications Technology development managers at an early stage of the value chain can co-create relationship benefits by building proposed business relationships integrating resources in a high-tech B2B market. In addition, marketing managers should consider the early stage as another source of value co-creation. Originality/value The notion of value co-creation is extended from the later stage to an early stage of the value chain in a high-tech B2B market. Consolidated framework of a value co-creation network integrating actors, resources and relationships, suggested in this study, will be valuable for further theoretical research and business application.

In this study, we proposed the concept of hyper-coopetition based on an investigation of the inter-organizational relationships of chipmakers. Hyper-coopetition is distinguished from traditional coopetition by having companies in heterogeneous industries as participants, whereas traditional coopetition is a relationship between competitors in the same industry. To investigate antecedents and processes of hyper-coopetition, we established the conceptual framework of hyper-coopetition through a literature review. We conducted a case study on leading chipmakers, including Intel, Samsung, and Nvidia, to investigate antecedents and processes of the chipmakers’ hyper-coopetition. By examining hyper-coopetition, we contributed to the relevant academic field by introducing hyper-coopetition, its typology, and a new research agenda. The analysis result also brought managerial implications for companies in a rapidly changing environment.

Value co-creation is an important business strategy these days in both the business-to-business (B2B) and business-to-consumer (B2C) markets. The aim of this study was to identify specialized resources and competences for value co-creation in the relationship network within a high-tech B2B market. A case of Taiwan Semiconductor Manufacturing Company Limited (TSMC) with customers and partners was chosen as the study case. Based on the observations, contents analysis of the secondary data and unstructured interviews with former TSMC employees, 4 critical resource types (financial, knowledge, efficiency and intellectual resource) and 6 competence types (relational, collaboration, strategic, innovation, managing and service capability), were performed as the principal factors for value co-creation in the relationship network. A research framework that can analyze the value co-creation phenomena in the relationship network was established.Key Words : value co-creation, relationship network, value, resource, competence
