中文摘要：

通过对考古发现的诸多史前至夏商时代城址进行分析可以发现，龙山文化时代是城郭之制的孕育、形成时期，藤花落、宝墩、石峁等城址已基本具备城郭之制特点，陶寺城址施行城郭之制的可能性非常大，但芒城、双河和紫竹村城址不属于城郭之制，只能算作双重城垣防御。夏代为城郭之制的初步发展阶段，新砦城址的布局实质上已具备城郭之制，望京楼城址具备城郭之制的布局特点。商代以后城郭之制得到推广，郑州商城、偃师商城、洹北商城等都城，以及垣曲商城、盘龙城、牛城、三星堆等方国城址，大多推行城郭之制。所谓“夏商无城郭说”或“夏代无城郭说”等观点是与考古实际不相符的。

英文摘要：

Through research the archaeological finds city sites from the Neolithic period to the Xia and Shang Dynasties, we found that the inner and outer city walls system begun to gestate and form in the Longs- ban culture period, like the city sits Tenghuangluo, Baodun, Shimao and so on already had the feature of in- ner and outer city walls system, especially the Taosi city site had great possibilities and Mangcheng, Shuanghe and Zizhucun city sites did not belong to the system of inner and outer city walls, their structure was olny as double-wall defense system. The Xia Dynasty was the preliminary developing stage of inner and outer city sys- tem, until the geographical layout of Xinzhai site was the inner and outer city walls in essence and Wangjin- glou site had the feature of the inner and outer city walls. The system of inner and outer city walls was extend- ed after the Shang Dynasty, such as Zhengzhou Shang capital site, Yangshi Shang capital site and Huanbei Shang site and other city sites, the Yuanqu Shangcheng site, Panlong site, Niucheng site, Sanxingdui site and other state city sites mostly adopted the inner and outer city walls system. These views that in the Xian and Shang Dynasties or in the Xia Dynasty have not inner and outer city walls are inconformity with the archaeological materials.
