This thesis examines whether companies listed in the Borsa Istanbul (BIST) Sustainability Index encourages sustainability practices of other companies in Borsa Istanbul Stock Exhange. With this aim, a two-stage logit model was used to measure the effects of mimetic pressure by BIST Sustainability Indexcompanies on the likelihood of sustainability reporting in various environments such as social and environmental risk levels, indices, and sectors. The model determines whether the mimetic pressure significantly affects releasing sustainability report in social and environmental risk levels, indices, and sectors and in which one the impact is highest. As a result of the analysis, it is seen that the increase in the number of BIST Sustainability Indexcompanies that publish sustainability reports increases the likelihood of sustainability reporting in companies with the same risk level, index, and sector. Among them, the effect of the mimetic pressure of BIST Sustainability Indexcompanies is the highest in indices The analysis results are compatible with the institutional theory since BIST Sustainability Indexcompanies' success in financial and sustainability performances makes them ideal models for other companies. Also, the result can be interpreted as the consequence index-based selection system of BIST Sustainability Index.
