In this chapter, historical background of the study was established and concept of Qin Culture was defined. The history and present situation of study of Qin Culture were summarized, the purpose and explanation theory of the paper was explained. It was pointed out that the changes in both basic social organization and constitution of ruling class during the transition from the system of enfeoffment to the system of empire in ancient China could be reflected in archaeological materials. It is just from the point of view of the changes in both basic organization and constitution of ruling class that the paper is going to examine and explain state systems of ancient China by archaeology.

建立本文研究的史学背景，界定秦文化，对秦文化研究的历史和现状进行了总结，并对本文研究的目的及解释理论进行了说明，提出在中国古代国家制度从封国向帝国的转变过程中，社会基本组织和统治集团成员这两方面的变化可以从考古资料上反映出来。

Firstly,I deduce the basic social structure of folk village from the graduallyhappening folk activity in this village.Secondly,I enucleate the"deeply description"on this village folk village acted on the factual movement in family and village.AT last,I point out the basic relationship between folk activity and market economy,betweenthe village and the state.
