内容概况：随着我国国民经济的持续发展与公路、市政等基础设施建设的不断推进，市场对沥青的需求 长期保持旺盛。在2020年之前，中国沥青产能整体呈现震荡上行的趋势，并于2020年达到阶段性峰值， 这主要得益于"十三五"规划收官之年大型道路项目集中收尾所带来的需求增量，从而刺激了产能的集中 释放。进入"十四五"时期，产能扩张步伐仍在继续，2023年全国沥青产能已增至7900万吨，当年新增产 能800万吨，同比增长11.27%，新增产能的地理分布仍以山东、河北等传统产区为主。持续的产能扩张 使得国内沥青市场长期处于供给过剩状态，炼厂的平均开工率常年维持在50%左右的较低水平。由于 2024年沥青生产利润降至近年来最低点，严重抑制了炼厂进一步释放产能的积极性，因此全年产能仅小 幅增长并稳定在8140万吨/年左右，行业进入以消化存量产能、优化运行效率为主导的新阶段。未来， 中国沥青产能的增长将受到多重因素抑制而趋于停滞。在需求端，受地方财政压力与基建项目审核趋严 影响，整体需求预计下滑；在供给端，潜在的消费税政策若落实将显著增加生产成本，削弱炼厂增产意 愿。 相关上市企业：中国石油（601857）、中国石化（600028 ...
