Purpose
Value co-creation (VCC) represents actors’ joint, communal or shared value-creating processes. However, while existing research has advanced important VCC-based insight, the use of differing metatheoretical lenses to study VCC incurs a risk of theoretical fragmentation, thus potentially hampering this research stream’s continued development. We, therefore, undertake an in-depth review of the corpus of VCC research that focuses on its common conceptual underpinnings as anchored in differing perspectives.

Design/methodology/approach
To explore this objective, we undertake an extensive review of extant VCC literature, based on which we develop an integrative conceptual framework of VCC.

Findings
We propose an integrative, metatheory-unifying definition and framework of VCC that reflect its core hallmarks and dynamics across its adopted theoretical perspectives. Based on the framework, we also derive a set of fundamental propositions (FPs) that synthesize VCC’s core tenets.

Research limitations/implications
VCC conceptualizations grounded in differing metatheoretical perspectives reveal the concept’s core interactive, value-creating nature across metatheoretical perspectives. Though VCC emanates from interactivity between any actor constellation, unifying different metatheories of VCC uncovers important insight.

Practical implications
The study suggests that for effective value co-creation, managers need to establish agreed-upon institutional arrangements, facilitate positive actor relationships and experiences and address challenges like collaboration, transparency, empathy and skill development while ensuring that affective, cognitive, economic and social dimensions of success are met for all actors involved. Successful initiatives require seamless communication, mutual understanding, cost-benefit favorability and public recognition of contributions.

Originality/value
Given VCC’s rising strategic importance, a plethora of studies have investigated this concept from differing metatheoretical perspectives, yielding potential VCC-based fragmentation. Addressing this gap, we take stock of the VCC literature with a view to distilling the concept’s core, trans-metatheoretical hallmarks, as synthesized in the proposed framework and FPs of VCC.
