Hsuntangpu sites have previously been found only in northern Taiwan. If a link between this site and the Hsuntangpu culture is confirmed, it will indicate that the Taoyuan plateau's prehistoric inhabitants exploited not just land routes, but also sea routes that extended into the Tanshui River area and the Taipei Basin, and even to Miaoli, Taichung and Hualien, which suggests a stunning level of advancement.
由於「訊塘埔文化」的各遺址多散佈在台灣北部，若能證實，也將證明曾經在桃園台地生活的史前人類，其互動或是對外貿易接觸往來範圍，除了陸路的桃園沖積扇區域外，還利用海路擴展至北台灣淡水河一帶與台北盆地內，甚至遠達苗栗、台中和花蓮，其進步程度令人讚嘆。
