This is a conceptual paper that synthesizes established literature in institutional theory, strategic management, and development economics to address a gap that most mainstream strategy frameworks have not adequately confronted: how do formal firms compete when a large portion of their competitive landscape consists of informal businesses operating entirely outside the regulatory system? The paper is written from the perspective of corporate managers, business leaders, and organizational decision makers who need both a clear understanding of the problem and a set of workable responses to it. Drawing on documented theoretical frameworks and real-market observations from developing and emerging economies, the paper traces why dual economic systems develop, what makes informal competitors genuinely difficult to displace, and what specific strategies formal firms can deploy to protect and grow their market position. The paper concludes with six practical advisories for managers, each accompanied by concrete implementation steps. Limitations of the conceptual approach are acknowledged, and directions for future empirical research are identified.
