本稿の目的は，牛肉を4品種に分類し，かつ時系列データの非定常性を考慮した上で，わが国牛肉需要構造を計量経済学的に明らかにし，環太平洋パートナーシップ（TPP）協定が国産牛肉生産に与える影響について考察することである．主な分析結果は次のとおりである．第1に，国産食肉よりも輸入食肉の方が，自己価格と食肉支出に対する需要の反応が大きい．第2に，TPP協定は，和牛肉と

肉の需要量に有意な影響を与えない一方，乳用牛肉の需要量を8.6％減少させる．第3に，TPP協定発効後は，牛肉関税化後と異なり，和牛肉の生産拡大によって乳用牛肉の生産縮小を埋め合わせるという貿易自由化の影響緩和効果を期待できない．

For sustainability of Japan's meat production, the meat production method which targets high marbling has possibility to reduce production costs because it should not depend on dense feed. In order to do that, establishing a market for non-high-marbling meat is important for promoting meat quality valuation without extent of marbling. The present research studied the case of the Company N, whose main sales item is artificially matured meat. Company N has developed this item as a strength, acquired by their long experience and investment. They produced its product line in consideration of consumer needs, developing it with real high demand. They based their production policy on the assumption of complete consumer use of the product line. By establishing a relationship of mutual trust together with both raw material producers connection and actual large demands, the company has structured a value chain based on their strengths, and became a core element of this chain for establishing a market for non-high-marbling meat.
