To understand flat bottom pottery, distributed in eastern midland and southern area of the Korean peninsula, understanding of Neolithic culture in the Northeast China, Primorye of Russia and Amur River area is necessary. In this thesis, to respond to the necessity, chronology and movements of the early era of Neolithic period in the Russian Primorye and nearby area are studied. Pottery of the early Neolithic era of Primorye and nearby area is divided into the following five types, depending on pattern and inlay method; sharp-bottomed pottery, stamped pottery, appliqued pottery, stepped-back comb pottery, and stepped-back blade pottery. After six-level change process, as the chart 11, is extracted, after reviewing order and parallel of the five pottery types based on layer excavation and coexistence relationship. And then, status of pottery culture is studied through analysis of each pottery class’s distributional change, coexistence and overlapping pottery class. While stamped pottery is located in lower area of the Primorye and the Amur River, in southern Primorye, sharp-bottomed pottery existed. It seems that sharp-bottomed pottery coexisted the flat bottomed stamp pottery. Afterward, in Primorye-Amur downstream area, stamp pattern gradually disappeared and comb-stamp pattern became popular, and in southern Primorye, Boisman-type stepped-back comb pattern, which inherited the tradition of sharp-bottomed pottery, appeared. Boismantype stepped-back comb pattern pottery is not found in the downstream of the Amur. In next level, Zarechye-type stepped-back comb pattern pottery expanded to wide area of the southern Primorye-Midstream of the Amur and Downstream of the Amur, causing the collapse of local character of the previous period. Therefore, such status of the pottery reflects movement of human groups, basically. In the early Neolithic period, groups of people in the Primorye and nearby area communicated closely through the network of information that was maintained by pottery type, and created new class of potteries without rupture of group. On the other hand, the existence period of the flat bottom pottery of eastern midland of Korea more or less correspond to the period when stamped pottery and Boisman-type pottery existed in Primorye. The change from stamp to comb in flat bottom pottery in eastern midland of Korea is also similar to that in Primorye. Perhaps, between the two regions, exchange network continuously existed. Boisman 1stperiod and Munamri 7th layer are when the exchange was particularly strong, and one of the most important achievements of this research is finding the accurate cross dating between the regions. Also, considering coexistence of diverse potteries in Primorye, the necessity to realize it as change to diverse classes, rather than linear change, is recognized.
