基于DEA-Malmquist方法构建城市群经济增长方式界定模型,对1990—2014年中国城市群经济增长方式进行判定分析。研究发现:(1)1990—2014年中国城市群经济增长可划分为四大阶段,包括1990—2000年的粗放增长期,2000—2004年的绝对粗放增长期,2004—2006年的粗放增长期以及2006—2014年的波动增长期,2014年中国城市群生产率增长率占经济增长率的比重达到0.65,处于集约增长阶段。(2)中国城市群经济增长方式在空间上可划分为集约型、粗放型及绝对粗放型三种类型,经济增长集约型城市群主要位于我国东部沿海地区,粗放型城市群主要位于中部及东北地区,绝对粗放型城市群均位于西部地区。(3)技术进步是东部沿海城市群的主要经济增长来源,而中西部尤其是西部地区的城市群,技术进步对经济增长的贡献较小。(4)中国城市群经济增长方式与城市群经济发展水平呈强相关,随着城市群经济水平的不断提高,经济增长方式会逐渐从粗放型向集约型方向转变。
Based on the DEA-Malmquist method, this paper constructs the definition model of urban agglomeration’s economic growth mode and makes a judgment analysis on the economic growth mode of Chinese urban agglomeration during 1990-2014. The main findings are as follows: (1) The economic growth of urban agglomerations in China from 1990 to 2014 can be divided into four major stages, including the extensive growth period from 1990 to 2000, the absolute extensive growth period from 2000 to 2004, the extensive growth period from 2004 to 2006 As well as the period of fluctuating growth from 2006 to 2014, the growth rate of productivity of China’s urban agglomerations accounted for 0.65 of the economic growth rate in 2014, in an intensive growth stage. (2) The pattern of economic growth in China’s urban agglomerations can be divided into three types: intensive, extensive and absolutely extensive. The intensive urban agglomerations with economic growth are mainly located in the eastern coastal areas of China. The extensive urban agglomerations are mainly located in the central and northeast Area, the absolute extensive city group are located in the western region. (3) Technological progress is the main source of economic growth in the eastern coastal city group, while the urban agglomerations in the central and western regions, especially in the western region, contribute less to economic growth. (4) The economic growth pattern of China’s urban agglomerations is strongly correlated with the economic development level of the urban agglomerations. With the continuous improvement of the urban agglomeration’s economic level, the economic growth pattern will gradually shift from extensive to intensive.
