投資是利用金融資本努力創(chuàng)造更多的財(cái)富。威廉·F.夏普《投資學(xué)基礎(chǔ)》投資是為未來收入貨幣而奉獻(xiàn)當(dāng)前的貨幣。

投資是指經(jīng)濟(jì)主體將一定的資金或資源投入某項(xiàng)事業(yè)，以獲得未來經(jīng)濟(jì)效益的經(jīng)濟(jì)活動(dòng)。OtherdefinitionsMacroeconomicsGNP=C+I+G+(X–M)MoneyorotherresourcesusedbybusinessestopurchasecapitalgoodsTwotypes:InvestmentonfixedassetsInvestmentoninventoryFormationofcapital;

金融資產(chǎn)與金融投資金融資產(chǎn)

金融資產(chǎn)是指一切代表未來收益或資產(chǎn)合法要求權(quán)的憑證，亦稱為金融工具或證券金融投資

金融投資主要是以金融資產(chǎn)為投資對(duì)象的投資。實(shí)質(zhì)是資金所有者和資金使用者的分離，是資產(chǎn)所有權(quán)和資產(chǎn)經(jīng)營權(quán)的分離

實(shí)物投資與金融投資

實(shí)物投資主要是以實(shí)物資產(chǎn)為對(duì)象，是投入資金以建造或購置固定資產(chǎn)和與之相聯(lián)系的流動(dòng)資產(chǎn)而取得收益的一種實(shí)際資產(chǎn)化的過程。實(shí)物資產(chǎn)是金融資產(chǎn)存在和發(fā)展的基礎(chǔ).

金融資產(chǎn)的收益最終來源于實(shí)物資產(chǎn)在社會(huì)再生產(chǎn)過程中的創(chuàng)造。金融投資是將貨幣資金轉(zhuǎn)化為金融資產(chǎn)，而不是轉(zhuǎn)化為實(shí)物資產(chǎn)，因而沒有引起社會(huì)再生產(chǎn)擴(kuò)大和社會(huì)總投資的增加。只有當(dāng)金融投資被直接投資者運(yùn)用于直接投資時(shí)，才會(huì)使社會(huì)總投資增加和社會(huì)再生產(chǎn)規(guī)模擴(kuò)大。FurtherThoughtsFinancialassetskeepveryclosetieswithrealassets.Thebreakupoffinancialassetsfromrealassetsmaycausebubblesinfinancialmarkets!1990sJapanesefinancialbubbles2007AmericanfinancialbubblesThebiggerbubbleoffinancialassets,themoredamagesofrealassets!ConceptCheck-1Arethefollowingassetsfinancial?
