Abstract: Through the review on the development of petrochemical industry in 2015, we analyze the factors which can impact oil-production industry, oil-service industry, oil refining and chemical industry, storage transportation and sales industry, and integration company in 2016. On the basis of these factors, we make a prediction of the outlook of the petrochemical industry:Suffering from low oil prices, oil-production industry will be under pressure; Oil-service industry remains profitable, but its growth will slow; Oil refining and chemical industry can seize the opportunity to make a profit; Storage transportation and sales industry may perform better progressively; Due to the difference of business, integration company's differentiation will be more obvious.
