The impact of command-and-control environmental regulation on enterprise total factor productivity: A quasi-natural experiment based on China's Two Control Zone policy

Command-and-control environmental regulation is a traditional environmental policy that is still widely used in developing countries. This study examined a rarely discussed but significant issue for environmental sustainability and economic developmentdthe impact of command-and-control environmental regulation on enterprise total factor productivity growthdbased on a large enterprise-level sample. Employing China's Two Control Zone policy as a quasi-natural experiment, we used a Chinese industrial enterprise panel dataset from 1998 to 2007 to estimate the effects of command-and-control environmental regulation in a difference-in-difference framework. It is found that command-and-control environmental regulation hassignificantly hindered the growth of enterprise total factor productivity, and this negative effect was lagging and continuous. In addition, we leaned that this negative effect mainly came from the increase in costs of enterprises and the negative impact on the enterprise resource allocation efficiency. When considering enterprise heterogeneity in terms of pollution intensity, size, and ownership, the study further found that the negative effects are exacerbated for enterprises in more heavily polluting industries, those of smaller size, and those owned by foreign companies, respectively. Our research is a reexamination of the Porter hypothesis in China, and fills the gap in the literature on the micro effects of command-and-control policy on enterprise total factor productivity for developing countries. Based on a rigorous empirical analysis, we conclude that it is difficult to achieve a winewin scenario with sustainable environmental development and enterprise total factor productivity growth under command-and-control environmental regulation. Environmental regulations should have clear objectives and take a flexible approach, and it is necessary to adopt diversified environmental regulation policies based on market instruments.
