Building on recent developments in optimal distinctiveness (OD) research, we identify two dimensions of corporate social responsibility (CSR) practices – CSR scope conformity and CSR emphasis differentiation – and examine the antecedents of both. We theorize that private ownership and enhanced media coverage may increase scope conformity and emphasis differentiation, while such effects may be contingent on industrial context. In socially contested industries, the impact of private ownership on scope conformity will be mitigated, and the impact of media coverage on scope conformity will be amplified. Meanwhile, in highly competitive industries, the impact of private ownership and media coverage on emphasis differentiation will be mitigated. We test our predictions using a database of 942 Chinese publicly listed firms between 2008 and 2016. Our findings imply that the choice of optimal CSR strategy has to be made in accordance with the embedding context. The multidimensionality view of OD enables firms to better orchestrate firms’ strategic positioning along different dimensions of complex practices, which leads to better customization of societal expectations and the industrial competitive landscape.
