Conclusion
Institutional complexity as well as the implementation of CSR are frequently studied topics in business and society research. Despite this fact, the role of micro-level processes in both topics has not yet been subject to comprehensive research. A focus on those processes, however, is highly relevant to understand how logics in general and CSR specifically become effective. Moreover, a micro-level perspective enables scholars to better understand the (temporal) interplay of individuals, organizations, and fields in this context. To address this research gap, we applied a longitudinal approach on the micro-level process underlying CSR implementation. Our study has shown that CSR managers apply four specific strategies to promote CSR implementation and cope with the tensions between social and environmental elements and economic and technical concerns. In most cases, all four strategies are applied simultaneously but with varying degrees of intensity. We have also shown that organizational characteristics influence the intensity with which these strategies are applied, and the intensity of strategy application shapes organizational behavior over time. The comprehensive model that integrates our findings on the (temporal) interplay of individuals, organizations, and fields may encourage other researchers to study other types of implementation processes and compare findings to develop a generalized model of implementation processes.
