Does environmental regulation reduce China’s haze pollution? An empirical analysis based on panel quantile regression

Abstract

Haze pollution in China is very serious and has become the source of mortality, affecting the health and lives of residents. The Chinese government adopts different policy measures to reduce haze pollution. The impact of different types of environmental regulations on haze pollution has become a hot topic for academics and government departments. Based on panel data from 2005–2017, this paper studies the effect of different types of environmental regulations on haze pollution in 30 provinces of China using a panel quantile model. The results show that when haze pollution changes from a low quantile to a high quantile, the marginal impact of command-and-control environmental regulation on haze pollution changes from 0.122 to -0.332. Command-and-control environmental regulation can reduce haze pollution, but its impact is not significant. The main reason for this finding is that environmental law enforcement is not strict. The marginal impact of economically restrained environmental regulation on haze pollution changes from -14.389 to 49.939. Economically restrained environmental regulation can reduce haze pollution in low quantiles, but not in high quantiles. The collection of sewage charges fees is far less than the total profit, which has no deterrent effect on enterprises. The marginal impact of public participation in environmental regulation on haze pollution changes from 0.154 to -0.002. Public participation in environmental regulation cannot reduce haze pollution in low quantiles, but can in high quantiles; however its impact becomes insignificant. This study reveals the quantile-based discrepancy in the effect of environmental regulation on haze pollution, and offers a new perspective for research on the effects of environmental regulation.

Air Quality and Residents’ Health in China: An Empirical Analysis Based on Spatial Simultaneous Equations

“…The industrial structure can effectively improve energy efficiency and reduce environmental pollution [56], and the optimization of the proportion of secondary industry can promote green economic development and effectively improve air quality [57,58]. If science and technology investment is used in clean and environmental protection technology innovation, air quality will be improved [59][60][61].…”

The Impact of Technological Innovation and Industrial Structure Upgrading on New Urbanization: An Empirical Analysis Based on Panel Quantile Regression

“…The empirical investigation by (Wu et al, 2016) affirmed that secondary and tertiary industries and technological progress are the two main factors influencing the urbanization of Baotou City, and the urban expansion was affected by the integration of technology and industry. A recent study by (Li & Li, 2020) stated that economic development in the Pearl River Delta region has shifted from factor-driven to innovation-driven, and new job opportunities are created by automation and technological progress, which will become a key driving force for China's urbanization. Based on the comprehensive index system of new urbanization and technological innovation, (Shang et al, 2018) established regression analysis to prove that there is a long-term balanced positive relationship between technological innovation and new urbanization in Shaanxi Province.…”

Research on the Pollutant Emission Reduction Strategy and Simulation of Paper-Making Enterprises under the Reward and Punishment Mechanism

“…One is that many authors studied the reduction and governance of the enterprises' pollution from the perspective of environmental regulations. Most scholars believed that environmental regulations can effectively reduce environmental pollution [5][6][7]. Some scholars also believed that environmental regulations have different impacts on enterprises with different pollution levels-the impacts on pollution-intensive enterprises was much greater than that on cleaning enterprises [8].…”
