How do subsidiaries sell initiatives to their headquarters? Multilayer decision-makers at corporate headquarters, with divergent interests and power, can overly complicate the acceptance process. We present a multi-case study to explore how subsidiaries of a Chinese multinational enterprise convince top management teams and department heads at their corporate headquarters to engage in foreign investments. Building on a micropolitical perspective, we develop a process model of subsidiary micropolitical strategy adoption consisting of (a) political tension retrieval regarding divergent interests and power at corporate headquarters around specific initiatives, (b) selective coalition building whose interests and power are aligned with the initiatives, and (c) a transitive relation leveraging strategy based on the ties of allied headquarters' managers. We further reveal the interplay between corporate motivations (i.e., market seeking vs. strategic asset seeking) and specific micropolitical activities adopted by subsidiary managers. We enhance the understanding of micropolitics in subsidiary initiatives by underscoring how to strategically manage differences among multilayer actors at corporate headquarters. Additionally, we reveal a political view of foreign investment decision-making in addition to rationality.
