项目摘要

比較静学モデルによる価格伝達分析を行い,硬質小麦の政府売渡価格やふすまの市場動向,製粉・製パン業の非農業部門など,これらの外生変数による小麦製品の価格変化率に対する寄与率を計測し,小麦政府売渡制度の相対的影響度を明らかにした.高度経済成長期を終え,非農業部門からのコスト上昇圧力が緩和した1980年代半ば以降,小麦の政策価格は,食パン価格の変化に対して,それ以前よりも相対的に強い影響を与えている.1980年代後半以降の小麦価格の引き下げ期に,小麦粉価格の低下が不十分であった要因について,定量分析を行った.製粉大手企業は原料費削減による残余資金を原資に,製販統合・経営多角化を推進し,食品販売部門の強化を図っている.よって,硬質小麦の政府売渡価格の引き下げは,強力粉価格の低下に十分反映されていない.価格支持政策から直接支払政策への農政転換は,必ずしも消費者利益の増加につながるとは限らない.強力粉価格が低下した1980年代後半以降,食パン卸売価格が下方硬直的であった要因を推測的変動モデルで定量分析を行った.製パン大手企業の販路拡大競争と製パン小売業の台頭によって70年代後半,低価格戦略が取られたが,その後,企業合併等で市場集中度が高まると,価格は下方硬直的となった.食品製造業全体を上回る製パン業の人件費の伸びも影響した.70年代後半の市場競争性があれば,90年代末の価格水準は,約6〜12%低いと推定される.規模の経済性をもつ不完全競争下の食品産業を想定し,農業効率化と輸入関税削減が,農産物から加工食品への価格伝達性に対してどのような効果をもたらし,農業生産者と最終消費者にどのような影響を与えるのか,McCorristonらのモデルをもとに理論的考察を行った.農業効率化と関税削減をいかに進めるかだけでなく,加工食品市場の競争性をいかに高めるかという論点も,最終消費者だけでなく農業生産者の利益の確保のために,重要である.

In the comparative study, the market trends of durum wheat government marketing system, the non-agricultural sectors of flour milling and processing industry, the exogenous factors, the wheat product quality change rate, the delivery rate, and the corresponding impact of wheat government marketing system were analyzed. At the end of the high growth period, the rising pressure of non-agricultural sectors has been moderated since the mid-1980s, and the policy of wheat has changed from food to food, and the previous two have had strong effects on it. In the second half of the 1980s, the decline of wheat flour has not been very significant. Quantitative analysis has been carried out. Flour processing enterprises reduce raw material costs, reduce residual funds, promote diversification of production and marketing, and strengthen food marketing departments. In addition, the government of durum wheat is responsible for the reduction of grain yield, and the reduction of grain yield is very reflected in the middle of the market. The policy of supporting agriculture and politics must be changed from direct support to direct support, and the interests of consumers must be increased. Strong powder grid has been declining since the second half of the 1980s, and the food and clothing grid has been hard and straight below. In the late 1970s, the market concentration of large enterprises was high, and the market concentration of small enterprises was high. Food manufacturing industry as a whole has been affected by the expansion of labor costs in the manufacturing industry. The market competitiveness in the second half of the 1970s has been reduced, and the standard level in the late 1990s has been reduced by about 6 ~ 12%. The food industry under imperfect competition is expected to be stable in terms of scale, agricultural efficiency, import tariff reduction, agricultural products, processed foods, and the like. Agricultural efficiency and tariff reduction are important for ensuring the competitiveness of processed food markets and for ensuring the interests of agricultural producers for final consumers.
