Meta-study is a relevant analytical tool for studying emerging issues in the field of Corporate Social Responsibility (CSR) because of heterogeneous and conflicting research findings. When viewed as a methodological approach in CSR research, a meta-study has four sequential and reinforcing stages, namely: meta-method, meta-theory, meta-data analysis and meta-synthesis. The purpose of this chapter is to discuss meta-study as a useful technique for research, its stages and justifications for adopting a meta-study in CSR research. The chapter contribution discusses the steps involved in conducting a CSR research using meta-study. The implication of the chapter is that a meta-study gives a deeper, reliable and richer outcome compared with an individual research finding. The implication of the conclusion is that the insights gained from meta-study serve as legitimate sources of knowledge for researchers in the field of CSR for synthesizing findings from both qualitative and quantitative research in the field of CSR.
