Filed: 2021-05-08
Abstract: 【課題】製品を買い占め、オンライン通販で生産者が定める希望小売り価格より高額な金額で販売する事例が多発している。サスティナビリティの観点からは、原材料の生産地⇒加工地⇒消費地間における物理的な移動距離が少ない事と、需要予測の精度を上げる事で廃棄される量を削減する事が重要だが、製品を買い占めオンラインで販売する行為は物理的な移動距離を増やし需要予測を困難にする。【解決手段】酒類の通販は免許制であるため、酒類をオンライン通販で販売する際に、Webページに所定の書式で通販の免許番号を記載する事を義務付け、Webページに記載された免許番号毎に通販事業者名、商品名、生産者が定める希望小売単価、Webページの販売単価、希望小売単価に対する販売対価の割合を集計し、国税庁や税務署と言った公的機関、生産者、流通関係者が確認出来る通販価格の抑制システムを提供する。【選択図】図１
