Does corporate social responsibility disclosure improve firm investment efficiency?

Purpose The purpose of this paper is to investigate the impact of corporate social responsibility (CSR) disclosure on firm-level investment efficiency. Design/methodology/approach An econometric model is used to estimate the impact of CSR reporting on investment efficiency on a sample of listed Chinese firms during the period from 2010 to 2013. Financial reporting quality is included in the model as a control variable. Investment efficiency is estimated based on existing models. Two scenarios are identified: under-investment and over-investment. Findings The results provide evidence of a higher level of investment efficiency for CSR reporting firms than for non-reporting firms. This relationship is, however, more pronounced in the over-investment scenario than in the under-investment scenario. In addition, the association between CSR disclosure and investment efficiency is stronger for firms with lower financial reporting quality (FRQ). These findings support the hypothesis that CSR disclosure provides effective incremental information that contributes to reduce information asymmetry and promote investment efficiency. Originality/value This is the first paper that directly tests the association between CSR disclosure and firm-level investment efficiency. The results suggest that firms and investors should consider the effect of CSR disclosure on information asymmetry and its impact on the availability and cost of capital. This work also contributes to the understanding of the economic impacts of CSR disclosure and provides arguments for regulatory entities to enforce CSR disclosure.
