Research on environmental economic policy system of industrial air pollution control

The environmental economic policies for industrial air pollution control in the process of industrial energy utilization were analyzed by classifying and analyzing the current policies from the aspects of industrial structure adjustment, energy efficiency optimization and pollution discharge management, simulating the development scenarios of different types of cities in China, and proposing corresponding policy combination choices. For "quantity expansion" cities, VAT preferential policies and credit financing support policies were recommended to encourage the development of environmentally friendly and technologically innovative industries. For "resource-dependent" cities, it is suggested to set suitable ad valorem resource tax rate, promote tradable emission permits, supplemented by energy efficiency leader system, so as to guide industrial structure adjustment and encourage enterprises to improve energy efficiency, while conducting stricter management of pollutant emissions. For "comprehensive development-oriented" cities, it is desirable to promote the corporate environmental credit reward and punishment mechanism, give full play to the importance of the credit system in the modern economy, promote the development of environmentally friendly enterprises, and constrain and promote the enterprise to take into account both business development and environmental responsibility.
