1、第35卷第5期經(jīng)濟(jì)地理Vol.35,No.52015年5月ECONOMICGEOGRAPHYMay,2015長江經(jīng)濟(jì)帶市域經(jīng)濟(jì)格局演變及其影響因素1112曾浩,余瑞祥,左椏菲,丁鐳(1.中國地質(zhì)大學(xué)(武漢)經(jīng)濟(jì)管理學(xué)院,中國湖北武漢430074;2.中國地質(zhì)大學(xué)(武漢)環(huán)境學(xué)院,中國湖北武漢430074)摘要:運(yùn)用空間自相關(guān)和空間計(jì)量方法對長江經(jīng)濟(jì)帶市域經(jīng)濟(jì)差異的時空演變及影響因素進(jìn)行了分析。結(jié)果表明:總體上長江經(jīng)濟(jì)帶市域經(jīng)濟(jì)差異呈現(xiàn)出先增大再縮小的發(fā)展趨勢。長江經(jīng)濟(jì)帶經(jīng)濟(jì)表現(xiàn)出較強(qiáng)的空間相關(guān)性,高值和低值集聚現(xiàn)象顯著,“高高”
2、集聚較穩(wěn)定在長三角地區(qū),“低低”集聚有向分散的趨勢發(fā)展;運(yùn)用空間計(jì)量方法對兩個階段市域經(jīng)濟(jì)的影響因素進(jìn)行了對比研究,分析得出財(cái)政收入和人口密度在兩階段由第一階段的負(fù)效應(yīng)作用轉(zhuǎn)變成了第二階段的正效應(yīng)作用,財(cái)政支出在第一階段的正效應(yīng)作用轉(zhuǎn)變成了第二階段的負(fù)效應(yīng)作用,經(jīng)濟(jì)結(jié)構(gòu)和固定資產(chǎn)投資在兩階段都起著正效應(yīng)作用,兩階段中固定資產(chǎn)投資的正效應(yīng)都為最大,第二產(chǎn)業(yè)比重、第三產(chǎn)業(yè)比重和固定資產(chǎn)投資正效應(yīng)作用上升明顯。關(guān)鍵詞:市域經(jīng)濟(jì);時空演變;影響因素;長江經(jīng)濟(jì)帶中圖分類號:F127文獻(xiàn)標(biāo)志碼:A文章編號:1000-8462(2015)05
