当前全球油气行业依然处于困境之中，原油价格持续低迷，油气产量供大于 求，过去传统的粗放式发展模式难以继续维持，各大石油企业被迫从“市场与销售 端”的企业竞争转变到“创新与采购端”的供应链竞争，通过运用世界先进的采购实 践经验和管理工具，实现供应链协同创新，降低企业运营成本，增加企业经济效 益。而采购管理作为影响企业成本与弹性的关键因素，也是供应链管理的核心环 节，对其进行研究分析与优化改进具有现实指导意义。 本文以A公司为例，从实际应用的角度出发，着重研究了该公司的采购管理 体系。首先，介绍A公司采购管理各方面的基本情况，并从采购管理组织机构、 采购模式、供应商管理及供应链一体化管理等方面分析了存在的问题，深入剖析 了影响采购成本、采购效率的问题原因。其次，提出了建立集中式采购组织结构、 实行品类化采购、基于产品定位分析科学实施采购策略、优化采购制度、优化供 应商绩效考核体系，将程序化采办向供应链一体化采办方向转变等改进方案。最 后，为保障整个采购管理优化方案能够顺利实施，制定了相关保障措施。虽然本 文是对A公司采购管理的个案研究，但其优化方案可以为行业内其它国有企业采 购管理改革提供参考和借鉴，也进一步提高了采购管理在现代企业中的应用价值。 关键词：采购管理，国有企业，采购模式，采购策略 Ⅱ ABSTRACT At present, the global oil and gas industry is still in a dilemma, crude oil prices continue to slump, and the supply of oil and gas is in excess of demand.
