1、我國(guó)農(nóng)民收入影響因素的回歸分析本文力圖應(yīng)用適當(dāng)?shù)亩嘣€性回歸模型,對(duì)有關(guān)農(nóng)民收入的歷史數(shù)據(jù)和現(xiàn)狀進(jìn)行分析,探討影響農(nóng)民收入的主要因素,并在此基礎(chǔ)上對(duì)如何增加農(nóng)民收入提出相應(yīng)的政策建議。?農(nóng)民收入水平的度量常采用人均純收入指標(biāo)。影響農(nóng)民收入增長(zhǎng)的因素是多方面的,既有結(jié)構(gòu)性矛盾因素,又有體制性障礙因素。但可以歸納為以下幾個(gè)方面:一是農(nóng)產(chǎn)品收購(gòu)價(jià)格水平。二是農(nóng)業(yè)剩余勞動(dòng)力轉(zhuǎn)移水平。三是城市化、工業(yè)化水平。四是農(nóng)業(yè)產(chǎn)業(yè)結(jié)構(gòu)狀況。五是農(nóng)業(yè)投入水平??紤]到復(fù)雜性和可行性,所以對(duì)農(nóng)業(yè)投入與農(nóng)民收入,本文暫不作討論。因此,以全國(guó)為例,把農(nóng)民收入與各影響因素關(guān)系進(jìn)行線性回歸
