宏观持续提振，需求拉动有限

1. Report Industry Investment Rating - Unilateral: Neutral; - Inter - period: PL01 - 05 reverse spread; - Inter - variety: Long PL2601 and short PP2509 [4] 2. Core Viewpoints - Macro policies such as anti - involution and elimination of backward production capacity continue to boost the propylene and polyolefin markets. The elimination of backward production capacity in the propylene industry is expected to shift the domestic propylene market from an oversupply to a tight - balance situation. However, the current overall propylene operating rate is at a seasonally low level, and downstream demand has limited driving force. For polyolefins, although macro policies boost the market, the cost - side support is weak, and downstream demand remains weak during the seasonal off - season [3] 3.
