Gig economy is a contemporary labor market structure characterized by the prevalence of contingent work arrangements, typically short-term, task-specific, or project-based engagements performed by independent contractors or freelancers, frequently facilitated by digital platforms, rather than traditional long-term employer-employee relationships. As a research concept, it serves to analyze the dynamics of this labor market transformation, examining its drivers, socioeconomic consequences for workers and firms, the technological infrastructure enabling it, and the regulatory and policy implications, thereby illuminating shifts in employment stability, income variability, and the future of labor.
