具体的な検討対象として，土器と集落を取り上げた。土器については，編年や併行関係の検討とともに，系統的な視点に基づく様式構造の把握を試みた。それによって，遠隔地間交流の活発化や地域間関係の変化，生駒西麓系土器の広域的な伝播などを明らかにした。これらを踏まえて，後期前葉の土器様式の展開は広域的な連動性を有し，かつ多元的，多核的なものであったと考えた。集落の検討では，中期と後期の移行期における集落の断絶や，後期前葉の集落数減少と集落分布密度の低下，集落の高所立地傾向を広く確認できたが，集落差の存在も明らかになった。こうした点は，中期から後期への移行期の社会変化が広域的な連動性とともに地域性を有したことと，社会変化の諸要因に対して地域ごとに柔軟な適応行動がなされたことを示唆する。
以上の検討結果を基に，当該期の考古資料の変化は，地域間交流の活発化と集団間関係の再編および社会的緊張の高まりといった事象を反映したものであり，当該期に生じた広汎な人口減少がその要因となった可能性を指摘した。さらに，これを踏まえた試論として，暦年代や木材年輪セルロース酸素同位体比にかかる研究成果との対比を行い，弥生時代中期後葉の湿潤化によって生じた食糧生産量の変化と人口変動を契機として，長期的・継続的に社会変化が進行したという見通しを示した。, The social and cultural changes from the middle to the late Yayoi period are considered to be the most significant milestone in the Yayoi period. Hypotheses based on various perspectives such as politics, economy, and environment have been presented as to the cause of the change. However, a leading hypothesis has not yet been put forward. Therefore, we conducted a basic study with common standards in multiple regions in the southern part of the Kinki region and tried to clarify the social changes during the period. Then, the content and background of the change were comprehensively considered by elucidating interregional exchanges and environmental changes.
The main objects to be examined are pottery and villages. Regarding pottery, we examined the chronology and the parallel relationship and tried to systematically grasp the stylistic structure. In doing so, it was clarified that the exchange between remote areas became active, the relationship between regions changed, and the widespread transmission of pottery from the west foot area of Mt. Ikoma. From these facts, it was considered that the change of the pottery style in the initial phase of the late Yayoi period was linked to a wide area and had multiple centres. In the investigation of the settlements, it was confirmed in a wide area that the settlements were disrupted during the transition period from the middle to the late Yayoi period, the number and the distribution density of the settlements decreased in the latest phase of the late Yayoi period, and the settlements tended to be located in high places. On the other hand, there were differences in these trends between settlements. These points indicate that social changes during the transition period from the middle to the late Yayoi period were widely linked besides regional differences and that multiple factors which change society were flexibly adapted in each region.
Based on the above investigation results, we clarified that the changes in pottery and settlements during the transition period from the middle to the late Yayoi period reflect the activation of interregional exchanges and the reorganization of intergroup relations, and the rise of social tension. Also, we pointed out that the population decline during that period may be the cause. Then, based on the comparison with the research results on the chronology and paleoclimatic reconstruction using tree-ring oxygen isotopic ratios, we considered that long-term and continuous social transformation was triggered by fluctuation in food production and population changes due to increasing rainfall in the latter half of the middle Yayoi period.},
