【摘要】：東部沿海地區(qū)城市群是國家經(jīng)濟發(fā)展的戰(zhàn)略核心區(qū)和國家新型城鎮(zhèn)化的主體區(qū)之一,其經(jīng)濟—生態(tài)可持續(xù)發(fā)展問題是近年來地理研究領(lǐng)域的前沿主題。首先對城市群生態(tài)效率進行定義并將其作為城市群可持續(xù)發(fā)展測度指標;隨后運用傳統(tǒng)DEA模型及非期望產(chǎn)出SBM模型,對東部沿海地區(qū)四大城市群在2005年、2011年、2014年三個時間截面中的經(jīng)濟效率、生態(tài)效率進行比較評價并分析了城市群生態(tài)效率時空演變特征;最后通過松弛度分析,為改善沿海地區(qū)四大城市群生態(tài)效率提供了對應(yīng)建議。結(jié)果表明:(1)山東半島城市群、長三角城市群、珠三角城市群經(jīng)濟綜合效率呈先下降后上升的V字型演變格局,而京津冀城市群經(jīng)濟綜合效率始終呈下降趨勢,2011年前其受純技術(shù)效率影響較大,2011年后受規(guī)模效率影響較大;(2)京津冀城市群受污染影響帶來的效率損失最大,山東半島城市群相對較小,總體而言,四大城市群生態(tài)效率在2005-2011年為下行期,2011-2014為修復(fù)期;(3)沿海四大城市群內(nèi)城市生態(tài)效率時空格局具有不同的演化特征,核心城市周邊以及沿海沿江地區(qū)城市生態(tài)效率相對較優(yōu),內(nèi)陸城市則較低;(4)京津冀城市群、長三角城市群、珠三角城市群核心城市資源消耗強度高、經(jīng)濟效益產(chǎn)出高、生態(tài)效率高,從整體來看,城市群內(nèi)多數(shù)城市呈污染物排放量下降趨勢,污染物治理效果較為明顯,環(huán)境影響問題有所改善;(5)影響東部四大城市群經(jīng)濟生態(tài)效率的原因不同,本文從城市群角度進行了差異性分析,并提出了合理化建議。
[Abstract]:The urban agglomeration in the eastern coastal areas is one of the strategic core areas of the national economic development and one of the main areas of the new urbanization of the country. The problem of economic-ecological sustainable development is the frontier topic in the field of geography research in recent years. Firstly, the ecological efficiency of urban agglomeration is defined and used as the measure index of sustainable development of urban agglomeration. Then using the traditional DEA model and the non-expected output SBM model, the economic efficiency of the four urban agglomerations in the eastern coastal areas in 2005, 2011 and 2014 were analyzed. The ecological efficiency of urban agglomeration is evaluated comparatively and the characteristics of spatial and temporal evolution of ecological efficiency of urban agglomeration are analyzed. Finally, through the relaxation analysis, it provides corresponding suggestions for improving the ecological efficiency of the four urban agglomerations in coastal areas. The results show that the Shandong Peninsula urban agglomeration and the Yangtze River Delta urban agglomeration. The economic comprehensive efficiency of Pearl River Delta urban agglomeration decreased first and then increased, while the economic comprehensive efficiency of Beijing-Tianjin-Hebei urban agglomeration showed a downward trend. Before 2011, it was greatly affected by pure technical efficiency. After 2011, it was greatly affected by scale efficiency. 2) Beijing-Tianjin-Hebei urban agglomeration suffered the biggest loss of efficiency caused by pollution, and the Shandong Peninsula urban agglomeration was relatively small. Overall, the ecological efficiency of the four urban agglomerations was in the downward period from 2005 to 2011. (a) the restoration period 2011-2014; 3) the spatial and temporal patterns of urban ecological efficiency in the four urban agglomerations along the coast have different evolution characteristics. The urban ecological efficiency of the core cities and the coastal areas along the Yangtze River is relatively better, while that of the inland cities is relatively low. 4) Beijing-Tianjin-Hebei urban agglomeration, Yangtze River Delta urban agglomeration and Pearl River Delta urban agglomeration have high resource consumption intensity, high economic benefit and high ecological efficiency. Most cities in urban agglomeration showed a decreasing trend of pollutant emission, the effect of pollutant treatment was obvious, and the environmental impact problem was improved. 5) the reasons that affect the economic and ecological efficiency of the four urban agglomerations in the east are different. This paper analyzes the differences from the angle of urban agglomeration, and puts forward some reasonable suggestions.
