The Archaeological Study of the Coastal Region of South China and Ryukyu Islands in the Second Millennium B. C.

本研究的重点是比较区域文化的动态和区域间关系的各个方面。华南由长江盆地和东南盆地组成。尤其是公元前第二个千年。中国古代的国家形成就发生在这一时期，这一事件对邻国产生了很大的影响。华南沿海地区正在形成自己独特的文化。在公元前2000年，中国东南沿海沿线的短途和长途互动形成了复杂的网络系统。这一时期，几个地区之间的互动由技术、货物、人员等多种运动组成。在中国东南沿海地区的激烈互动中引发的问题是，这个网络是否包括琉球群岛。在构成地域文化的诸多要素中，本研究更多地分析了各地域本土元素的变迁，而非外来元素的分布。“不连续性”是长江下游流域文化要素的特征，与中国东南地区公元前2000年的“连续性”形成鲜明对比。值得注意的是，琉球诸岛的地域文化也在同一时期发生了转变。互动变化与文化变化之间的关系仍然是区域文化动态研究的一个重要问题。

This study focused on the comparison of the dynamics of regional cultures and the aspects of the inter-regional relationships. South China consists of the lower basins of Chang Jiang and Southeast China. The second millennium B. C. is especially focused on. State formation in the ancient China occurred in this period and this event greatly affected its neighbors. The coastal regions of South China were under the formation process of their own distinct cultures.Interactions both through short-distance and long-distance formed the complex network system along the offshore route of Southeast China in the second millennium B. C. The interaction between several regions on this period was comprised of several kinds of movement like technology, goods, people and so on. The issue aroused from the vigorous interaction along the coastal region of Southeast China is whether this network encompassed the Ryukyu Islands or not. Among the many elements composing the regional culture, this study rather analyzed the transition of indigenous elements in each region than pursued the distribution of exotic elements."Discontinuity" is the characteristic of cultural elements in the lower basin of the Chang Jiang, making explicit contrast to the 'continuity" of those in Southeast China in the second millennium B. C. It is noteworthy that regional cultures of the Ryukyu Islands also transformed in the same period. The relationship between the changes in interaction and those of culture continues to be an important issue for the study of the dynamics of regional cultures.
