27、章 資本結(jié)構(gòu)：基本概念15.4.3 關(guān)于MM理論說(shuō)明(P292)：MM認(rèn)為用債務(wù)代替權(quán)益，企業(yè)的總資產(chǎn)成本不會(huì)降低，即使債務(wù)比權(quán)益便宜。原因是當(dāng)債務(wù)增加時(shí)，剩余權(quán)益風(fēng)險(xiǎn)的風(fēng)險(xiǎn)增加。隨著剩余權(quán)益風(fēng)險(xiǎn)的風(fēng)險(xiǎn)增加，權(quán)益資本的成本也隨之增加。剩余權(quán)益資本成本的增加抵消了更高比例的低成本債務(wù)籌資。事實(shí)上，MM理論證明了這兩種作用恰好相互抵消。因此，企業(yè)價(jià)值和企業(yè)總資本成本（rWACC）與財(cái)務(wù)杠桿無(wú)關(guān)。第37頁(yè)，共53頁(yè)。第15章 資本結(jié)構(gòu)：基本概念無(wú)稅時(shí)MM理論的總結(jié)：MM Proposition IFirm value is not affected by leverage.The cash flow
