The Qin and Han dynastiess ownership of the land is in the nature of the different views have been presented In the Shang yang bianfa (商鞅變法) of this occasion is the reason the land began to upset my reason for being in a nationalized owned form(國有制) changes appeared and was a story in General.There is the commonly visible color that I have unearthed in the Yunmeng shuì hudì qín mu zhú jiǎn(雲夢睡虎地秦墓竹簡), Qīng chuān qín du(青川秦牘), Zhāng jia shān hàn jiǎn (張家山漢簡), etc.on the historical materials (史料).This is the reason for the conventional snow this time against the land owned by the shape of the nationalized reportedly claims that empowers.The history of this local land development should pay close attention.And since the · Hsia(夏).Yin(殷).Chou(周) Dynasty land early was formed via irrigation or drainage works in this area.Through of this the land for the purposes of tax collection was formed.In other words, it means that the ruling classan made An Official Land (公田).The Shang yang bianfa say land policies related to the specific historical materials that is kāiqiǎnmò (開阡陌) and zhìyuántián(制爰田).This is a country in which the clearing land establish qiǎnmò(阡陌) for the equity imposed tax.Nothing visible in the document that the purpose of the tax law withholding of destination reliably secured to the operating system.These are for the purpose of all people to stabilize their cultivation aspiring to increase.Through of this we received an integral part of the relationship that is the land of The Qin and Han dynastiess time changing with the tax collect system.An Official Land (公 田) and Private Land (私田) made up of the land of the ingredients also depending on the time.This research in these positions of The Qin and Han dynastiess land ownership review again.Through this I hope to illuminate the country structure of this time.
