1. Report Industry Investment Rating - There is no information about the report industry investment rating in the provided content. 2. Core View of the Report - The cost support for propylene has increased, and attention should be paid to the restocking rhythm of downstream industries after the holiday. The supply of propylene is expected to increase slightly, but the actual return of major PDH plants under the current profit pressure needs to be monitored. The demand may face pressure due to high propylene prices and compressed profits. The cost side is strongly supported by the rising international oil prices and propane prices.
