对夏文化与早商文化分界的探讨已进行了数十年,考古材料在不断丰富,研究论著在日渐增多,各种观点异彩纷呈。近年来,虽在部分问题上有趋同倾向,但距离统一为时尚远。形成这种局面的原因是多方面的。其中与每位研究者自身的学术状况有直接关系。同样是二里头文化,是否可以将其区分为夏商两种文化,分又分在哪两期之间却有不同说法;同样是郑州商城和偃师商城的材料,孰早孰晚结论却完全相反。凡此种种,让圈外人莫名其妙,甚至对考古学的科学性产生怀疑。夏商文化之分的探讨进展到这种程度举步维艰,实难继续深入。笔者在学习和研究这一问题时曾就其研讨过程,各家研 Discussions on the demarcation between Xia culture and early Shang culture have been carried out for decades. Archeological materials are constantly being enriched, research papers are on the rise, and various opinions are colorful. In recent years, although convergence tends to exist on some issues, it is far from being uniformed. There are many reasons for this situation. It is directly related to the academic status of each researcher. The same is two miles inside the culture, whether it can be divided into Xia and Shang two cultures, sub-divided into two periods there are different views; the same is the mall in Zhengzhou City and Yanshi Mall material, the sooner or later conclusion of which is complete in contrast. All of these make the outsiders inexplicable, even doubts about the scientific nature of archeology. The discussion on the culture of Xia and Shang Dynasties progressed to such an extent that it was difficult to proceed with the reality. When I studied and studied this issue, I discussed the process of its research
