On“Drag Effect” Measurement and Evolutionary Trend Analysis of Urbanization Based on Resource Combination
Abstract: Taking Anhui Province as an example ,the entropy method is used to calculate the composite in‐dex of resource combination .Based on Romer economic grow th dragging model and the semilog relation‐ship between economic growth and urbanization development ,partial least squares regression method is ap‐plied to measure the“drag effect” of economy and urbanization from resource combination .The grey GM (1 ,1) model is adopted to predict its trend .The results show that 1) the composite index of resource com‐bination was increased from 0 .138 8 in 1997 to 0 .869 0 in 2012 in Anhui Province;2) the annual average“drag effect” of economy and urbanization from resource combination is 0 .000 246 0 and 0 .002 851 respec‐tively ;3) the“drag effect” of urbanization from resource combination will be 0 .004 487 and 0 .005 675 in 2015 and 2020 respectively .Based on the results of the study ,the policy recommendations are proposed to mitigate the constraints of resource combination on urbanization from six aspects including relying on sci‐entific and technological innovation and enhancing the alternation of technical elements on resource envi‐ronment .
