Abstract: Building on China's achievements in independent innovation of petrochemical equipment during the 14th Five-Year Plan (2021-2025) period, this paper systematically analyzes the current status and trends of innovation and development in petrochemical equipment under the requirements for industrial transformation and upgrading and new quality productive forces cultivation during the 15th Five-Year Plan (2026-2030) period. Through typical engineering cases such as aromatics and ethylene projects, it discusses the supporting role of strengthening the independent innovation of petrochemical equipment in industrial transformation and upgrading. The paper conducts an in-depth analysis of prominent issues including deficiencies in core technologies and key materials, insufficient industrial chain collaboration, weak innovation support and inadequate standard systems. It puts forward strategic and operable countermeasures and suggestions from four dimensions: achieving breakthroughs in core technologies, fostering collaborative ecosystems, strengthening innovation support and improving standard systems. This provides both theoretical and practical foundations for achieving independent innovation breakthroughs in petrochemical equipment and empowering the high-quality development of the petrochemical industry during the 15th Five-Year Plan period.
