N잡 관련 국내·외 연구에 관한 체계적 문헌고찰

This study aims to systematically collect, synthesize, and analyze domestic and international prior research on “N-jobs” to understand its conceptual definition, motivations and causes, and further, to examine its impacts. To achieve this goal, the study adopted the systematic literature review process proposed by the National Evidence-based Healthcare Collaborating Agency (NECA) of Korea. Initially, 1, 014 studies were identified, and following the PRISMA flow chart, 64 studies were analyzed. The analysis yielded the following key findings: First, most studies on N-jobs have been conducted in the fields of business and economics, primarily employing quantitative methods to identify relations between N-jobs and related variables. Second, various terms such as side job, dual job, portfolio career, Multiple Job Holding, Moonlighting, Portfolio Career, and Hybrid Entrepreneurs have been used interchangeably, leading to some conceptual overlap. Third, motivations for N-jobs include economic needs, career development, psychological fulfillment, and socio-structural factors. Lastly, N-job was used as both an antecedent variable and an outcome variable, and was related to various variables. Based on these findings, the study discusses implications and provides suggestions for future research.
