5、居民消費(fèi)價(jià)格指數(shù)。 　　我國零售商品價(jià)格指數(shù)編制中的主要問題包括： 　　(1)代表規(guī)格品的選擇。 　　在編制價(jià)格指數(shù)時(shí)，只能選擇部分具有代表性的商品。 　　(2)典型地隧的選擇。 　　典型地區(qū)的選擇既要考慮代表性，也要注意類型上的多樣性以及地區(qū)分布上的合理性和穩(wěn)定性。 　　(3)商品價(jià)格的確定。 　　對(duì)所選代表性商品使用的足全社會(huì)綜合平均價(jià)。 　　(4)權(quán)數(shù)的確定。 　　我國目前的零售價(jià)格總指數(shù)足采用加權(quán)算術(shù)平均形式計(jì)算的，其權(quán)數(shù)是根據(jù)上年商品零售額資料，并根據(jù)當(dāng)年住戶調(diào)查資料予以調(diào)整后確定的。 　　(5)指數(shù)的汁算。 　　從1985年1月起，我國開始采用部分商品平均價(jià)格

6、法計(jì)算全社會(huì)商品零售價(jià)格總指數(shù)。其計(jì)算公式為： 　　 　　式中，k為個(gè)體指數(shù)或各層的類指數(shù)，w為各層零售額比重權(quán)數(shù)。 　　【例8多選題】我國目前編制的價(jià)格指數(shù)中，與人民生活關(guān)系最為密切的是(　　)。 　　A.農(nóng)業(yè)生產(chǎn)資料價(jià)格指數(shù) 　　B.商品零售價(jià)格指數(shù) 　　C.固定資產(chǎn)投資價(jià)格指數(shù) 　　D.居民消費(fèi)價(jià)格指數(shù) 　　E.農(nóng)產(chǎn)品收購價(jià)格指數(shù) 　　【答案】BD 　　【解析】本題考查價(jià)格指數(shù)。與人民生活關(guān)系最為密切的是商品零售價(jià)格指數(shù)和居民消費(fèi)價(jià)格指數(shù)。 　　(二)消費(fèi)價(jià)格指數(shù)——我國稱為居民消費(fèi)價(jià)格指數(shù) 　　1.概念 　　居民消費(fèi)價(jià)格指數(shù)是反映一定時(shí)期內(nèi)城鄉(xiāng)居民所購買的

7、生活消費(fèi)品價(jià)格和服務(wù)項(xiàng)目價(jià)格的變動(dòng)趨勢和程度的一種相對(duì)數(shù)。 　　居民消費(fèi)價(jià)格指數(shù)可就城鄉(xiāng)分別編制城市居民消費(fèi)價(jià)格指數(shù)和農(nóng)村居民消費(fèi)價(jià)格指數(shù)，也可就全社會(huì)編制全國居民消費(fèi)價(jià)格總指數(shù)。 　　2.作用 　　(1)能夠反映城鄉(xiāng)居民所購買的生活消費(fèi)品價(jià)格和服務(wù)項(xiàng)目價(jià)格的變動(dòng)趨勢和程度。 　　(2)能夠反映通貨膨脹的狀況。 　　通貨膨脹的嚴(yán)重程度一般用通貨膨脹率來反映，通貨膨脹率一般以居民消費(fèi)價(jià)格指數(shù)來表示。其計(jì)算公式為： 　　 　　(3)反映貨幣購買力變動(dòng)。 　　貨幣購買力是指單位貨幣能夠購買到的消費(fèi)品和服務(wù)的數(shù)量。居民消費(fèi)價(jià)格指數(shù)的倒數(shù)就是貨幣購買力指數(shù)，其計(jì)算公式為：
