Since the fourth quarter of 2011, the economic growth rate of the domestic chlor-alkali industry has accelerated and the downward pressure has increased. Since the beginning of this year, the industry has not shown signs of recovery, and the situation of overcapacity in the chlor-alkali industry has not been effectively reversed. Therefore, at the time when the two sessions are held, I suggest that the country can introduce relevant policies such as guidance, restrictions, and technical support so that the industry can get out of its predicament as soon as possible. The first is to raise industry access threshold. Statistics show that from 2001 to 2011, the annual production capacity of polyvinyl chloride (PVC) in China increased from 4 million tons to 21.62 million tons, and the annual production capacity of caustic soda increased from 10 million tons to 33.7 million tons. The apparent consumption of PVC increased from 5 million tons to 13 million tons, and the capacity expansion was significantly faster than the market capacity. Therefore, the state should take effective measures to eliminate backward production capacity and strictly control the total amount. At the same time, projects that have been approved for construction and put into operation should be strictly in accordance with the requirements specified in the access conditions for the chlor-alkali industry, and access management should be carried out. To implement differentiated electricity price, taxation and credit policies for enterprises of different levels of development, and promote the survival of the fittest and the inferior of the industry. The second is to establish energy control policies. During the "Twelfth Five-Year Plan" period, the state should continue to give energy-efficient benefits of ion-exchange membrane caustic soda rational price policy in industrial policy. At the same time, the chlor-alkali industry is encouraged to co-produce cogeneration with alkaline electricity and strive to increase energy efficiency. The market price should be given to the chlor-alkali industry for reasonable electricity prices, and policy support should be given to the chlor-alkali industry for energy conservation and emission reduction, waste energy use, and rational use of resources. The third is to increase support for independent innovation. The promotion and application of advanced process technologies such as mercury pollution prevention and control technology, dry acetylene generation, low mercury catalyst and hydrochloric acid desorption are important factors in advancing the sustainable development of the chlor-alkali industry. Therefore, it is recommended to encourage and increase capital investment to support the energy-saving emission reduction and clean production technology transformation in the chlor-alkali industry, support the promotion and application of domestic ion membrane, dry acetylene, and new dry process cement manufacturing technologies, and hope to use it in calcium carbide process PVC. New policies and financial support for the research and development of solid mercury catalysts and mercury-free catalysts. The fourth is to support the research and development of high value-added new products. In view of the current low-level repetitive construction of low-end general-purpose model products in the domestic chlor-alkali industry, the chlor-alkali industry should vigorously promote the development and application of special grade PVC resin products in the next few years. This is a key step in upgrading the industrial structure of the chlor-alkali industry. Therefore, it is hoped that government departments at all levels will increase investment in policies and funds to support independent innovation enterprises.
