The document summarizes the status and development of chemical industry parks in China. It notes that the number of parks increased dramatically from 17 in 2004 to over 500 by the end of 2015, though many lacked adequate infrastructure and management. The 13th Five-Year Plan aims to relocate more chemical production into parks and improve park quality by closing some parks and supporting relocation of larger companies. However, consolidating the large number of existing chemical companies into parks will require huge investments. The quality and long-term viability of some existing parks is uncertain given evolving environmental regulations.
