By analyzing the drivers of industry development, we consider that traditional Producer driven, buyer driven and mixed driven mode can't fundamentally explain the formation of industry value chain, and we give an explain based on cost push and technology-pull. Based on this two modes we give three kinds of industry value chain upgrade modes: intra-prod-uct upgrade, industry function chain upgrade and pure value chain upgrade. At last the article suggests that we shall consider industry strategy, development trend and self advantage during the upgrading process.%通过对产业发展驱动因素的分析,研究认为传统的生产者驱动、购买者驱动及混合驱动模式并不能从根本上解释产业价值链的形成,进而从成本推动和竞争带动技术推动的角度,分析了价值链层级的形成;根据这两类驱动因素,提出3种产业升级模式,即产品族内升级、产业功能链升级及价值链升级;最后简要说明了在采用这3类模式升级的过程中,需要从战略、发展趋势及本身能力优势上进行综合分析.
