This paper examines how microblade technology emerged in North China based on the case study of the newly excavated Xishi and Dongshi sites in the hinterland of North China. Used as the lithic production area, Xishi and Dongshi sites generated abundant lithic debris which show the presence of a precocious form of microblade techno-complex embedded within the blade techno-complex. Radiocarbon dating suggests that they are among the earliest microblade sites ever found in North China. A chaîne opératoire approach is used to analyze the lithic assemblage of these two sites to investigate the specific features of the precocious form of microblade technology and its correlations to blade technology. The results indicate that the precocious microblade assemblage shows close technical affinity with the blade assemblage but is different from blade technology due to the frequent appliance of the pressure method to produce smaller end products from more diminutive cores. It indicates that the emergence of microblade technology in North China was a local technological innovation based upon blade technology which diffused from Siberia-Mongolia. Its appearance reflects a culturally meditated technological adaptation to cope with environmental change during LGM (Last Glacial Maximum) period.

本文以华北腹地新近发掘的西施和东施遗址为例，研究了微刀片技术在华北地区的兴起。用作石板生产区的西施和东石遗址产生了大量的石屑碎片，这些碎片显示了嵌在叶片技术复合体内的早熟形式的微刀片技术复合体的存在。放射性碳年代测定表明，它们是华北地区最早发现的微刀片场所之一。尚佩尔歌剧方法用于分析这两个站点的岩性组合，以研究早熟形式的微刀片技术的具体特征及其与刀片技术的相关性。结果表明，早熟的微刀片组件与刀片组件显示出密切的技术亲和力，但由于频繁使用压力法从更小的芯子中生产较小的最终产品，因此与刀片技术有所不同。这说明华北微刀片技术的兴起是基于从西伯利亚-蒙古传播而来的刀片技术的本土技术创新。它的出现反映了LGM（上次冰河世纪）期间对文化进行的沉思技术改造，以应对环境变化。这说明华北微刀片技术的兴起是基于从西伯利亚-蒙古传播而来的刀片技术的本土技术创新。它的出现反映了LGM（上次冰河世纪）期间对文化进行的沉思技术改造，以应对环境变化。这说明华北微刀片技术的兴起是基于从西伯利亚-蒙古传播而来的刀片技术的本土技术创新。它的出现反映了LGM（上次冰河世纪）期间对文化进行的沉思技术改造，以应对环境变化。
