摘要: 經(jīng)濟(jì)效率與經(jīng)濟(jì)規(guī)模的耦合協(xié)調(diào)對(duì)欠發(fā)達(dá)地區(qū)經(jīng)濟(jì)高質(zhì)量發(fā)展意義重大。運(yùn)用DEA-MI模型、標(biāo)準(zhǔn)差橢圓、耦合協(xié)調(diào)模型等方法研究西藏縣域經(jīng)濟(jì)效率與經(jīng)濟(jì)規(guī)模的時(shí)空演變及耦合協(xié)調(diào)特征。結(jié)果表明:1)2018年西藏縣域經(jīng)濟(jì)效率與經(jīng)濟(jì)規(guī)模呈“東南高、西北低”的特征。研究期內(nèi)西藏經(jīng)濟(jì)全要素生產(chǎn)率波動(dòng)上升,技術(shù)效率及其細(xì)分的規(guī)模效率起推動(dòng)作用,技術(shù)進(jìn)步起制約作用。2)經(jīng)濟(jì)效率與經(jīng)濟(jì)規(guī)模存在低水平集...
