Initial Public Offerings and Air Pollution: Evidence from China

Abstract

Purpose - The purpose of this study is to investigate the impact of firms’ financing activities on the environment. Faced with a deteriorating global environment, both corporations and regulatory bodies have become more responsive to environmental conservation problems. However, existing literature has not adequately addressed the question of whether and how firms’ business activities influence the environment.

Design/methodology/approach – Using the daily air pollution indices of 120 Chinese cities from 2001 to 2012, this study found that air pollution is alleviated after firms’ initial public offerings (IPOs). This paper proposes that firms’ IPOs influence the ambient air pollution through three channels: production scale, technical reform and corporate governance effects.

Findings – The authors of this study found that the proceeds acquired in IPOs result in enlarged production scales that increase pollution, while the investment of these proceeds in social responsibility-related technical reform and enhanced corporate governance reduce pollution. Moreover, the authors discover that firms with a higher state ownership emit fewer pollutants, thus supporting the positive monitoring role of the Chinese government.

Originality/value – Although this study investigates the impact of IPOs on air quality in China, the proposed analytical framework also applies to studies of other financing activities in global markets. This study has important policy implications for government regulations in environmental controls.
