中国城市群经济增长方式识别及分异特征

Identification and Differentiation of Economic Growth Pattern of Urban Agglomeration in China

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 model, we construct the model of economic growth mode of Urban Agglomeration, and we analysis the economic growth mode of Chinese Urban Agglomeration in 1990-2014. Through the study we found： （1） Economic growth of China＇s urban agglomeration can be divided into four stages in 1990-2014. Including the extensive growth period of 1990-2000 years, 2000-2004 years of absolute extensive growth period, 2004- 2006 years of extensive growth period and 2006-2014 years of shock growth period. In 2014, the rate of productivity growth of urban agglomeration in China accounted for 0.65 of the rate of economic growth, which was in the stage of intensive growth. （2） The economic growth pattern of urban agglomeration in China can be divided into three types： intensive, extensive and absolute extensive in space. The intensive urban agglomeration of economic growth is mainly located in the eastern coastal areas of China, which is mainly located in the central and northeastern regions. （3） Technological progress is the main source of economic growth in the eastern coastal urban agglomeration, while the central and western regions, especially the urban agglomeration in the western region, contribute little to economic growth. （4） The economic growth pattern of China＇s urban agglomeration is strongly correlated with the level of economic development of urban agglomeration. With the continuous improvement of the level of economic development of urban agglomeration, economic growth will gradually shift from extensive to intensive.
