論の前半では，貝塚の5文化層の出土土器と，上下4層で実施した貝殻等の炭素14年代測定結果によって時間的な枠組みを確定し，これに基づき，出土したゴホウラ類（ゴホウラ・アツソデガイ）を分析して当地で行われた作業内容を復元し，時間的変化を述べた。後半ではこれを同時期の沖縄諸島にのこる貝殻集積の出土遺物と対応させて，貝殻産地と中継地・消費地の関係を検討し，高橋貝塚を貝交易上に位置づけた。論の要点は以下の通りである。
・高橋貝塚は弥生前期中葉に始まり，同中期前葉まで継続した集落遺跡であり，琉球列島産の大型巻貝を用いた腕輪の各製作段階を示す貝殻187点が残されている。これらの9割以上はゴホウラ類である。
・高橋貝塚人は当初から，沖縄貝塚人が作ったゴホウラの背面貝輪用粗加工品をもとに西北九州人のために背面貝輪を作り，さらにゴホウラ原貝から北部九州人のために腹面貝輪粗加工品を作り，これらを北の消費地に輸出していた。
・高橋貝塚人は途中から背面貝輪製品とともに粗加工品も合わせて作るようになった。
・腹面貝輪の製作では，ある段階で沖縄から粗加工品用の貝輪素材が届くようになり粗加工品生産の効率が上がるが，間もなく腹面貝輪粗加工品の生産拠点が高橋貝塚から沖縄に移り，高橋貝塚での腹面貝輪粗加工品の生産量は激減する。
・腹面貝輪粗加工品が中継地を介さずに消費地に届くようになると貝交易における高橋貝塚の存在価値は低下し，遺跡は衰退する。
・貝交易の中継地としての高橋貝塚の最大の特徴は，沖縄から届いた貝殻や貝輪素材を，製品化し，あるいは製品に一歩近づける加工を行って消費地に届けるという，貝交易初期の経済的役割を果たした点である。, The Takahashi shell mound is located in southern Kyūshū. It was a relay point for shell trade between the Okinawa Islands and northern Kyūshū during the Yayoi period. This paper attempts to describe the actual situation of the relay through the analysis of the traded shells left in the site as outlined below.

- The Takahashi shell mound is a settlement site that started in the middle of the early Yayoi period and continued to the latter part of the same period. The cultural layers from layer I to layer V are deposited almost horizontally, and 187 shell fragments in total have been excavated. They reveal all stages in the production process for bracelets from large conches from the Ryūkyū Islands. More than 90% of these are Strombus.
- The people living at Takahashi shell mound made two types of shell bracelets during the layer V period and exported them to different areas. One is a finished product of shell bracelets using the back of Strombus. This was made from roughly processed products that arrived from Okinawa and was exported to northwestern Kyūshū. The other was a roughly processed product using the abdomen of Strombus, which was exported to northern Kyūshū.
- During the period of layer IV, people began to produce roughly processed items from the back of shells for bracelets by themselves and exported these to northwestern Kyūshū.
- During the period of layer I and II, roughly processed products from the abdomen of Strombus begin to decrease at the Takahashi shell mound site, on the other hand, an increase of the same style of roughly processed products in sites of the Okinawa Islands can be observed parallel in time. Both phenomena indicate that the production base had moved from the Takahashi shell mound to Okinawa.
- Roughly processed products of the abdominal shell bracelets began to reach the consumption are in northern Kyūshū directly, without passing the Takahashi shell mound any more, such that the importance of the site as a relay point in shell trade decreased and the site itself declined soon.

The characteristic of Takahashi shell mound as a relay point is that it played an economic role in the early stages of shell trade by processing and exporting shells and roughly processed products materials that arrived from Okinawa for two consumption areas.},
