城市经济互动与城市群产业结构分析——基于珠三角城市群的实证研究

作者利用动态空间偏离/份额模型对珠三角城市群的实证研究发现：在2001-2013年间，珠三角城市群城市间经济互动显著增强，但其空间格局没有发生显著变化。珠三角城市群大部分城市都形成了正向的产业结构效应，除了广州和深圳以外，各市在第二产业发展上具有较大的优势，弥补了第一、第三产业的劣势。珠三角城市群内多数城市未形成空间竞争力净效应和空间区位效应，尚不能充分利用其他城市发展带来的积极影响，城市群专业化分工与协作水平有待提高，经济发展的空间结构调整有待深化。基于上述发现的政策建议是推进珠三角城市群内部的专业化分工和产业空间结构调整，构建错位发展、高效互动的产业协同发展格局。

Urban Economic Interaction and Industrial Structure of Urban Agglomeration: An Empirical Study Based on the Data of Pearl River Delta Urban Agglomeration

Based on the dynamic spatial shift-share model,the empirical research on the Pearl River Delta city group get the following conclusions.From 2001 to 2013, the economic interaction within the Pearl River Delta city group has been significantly enhanced, but the spatial pattern of urban economic interaction has not changed significantly. Most cities of Pearl River Delta city group has formed a positive industrial structural effect, every city except Guangzhou and Shenzhen has greater advantage in the development of the second industry, making up for the structural weaknesses in the first and third industry, but the growth lagging of service industry has also restricted economic growth. However most of cities in the Pearl River Delta haven't formed the net spatial competition effect and spatial location effect,these cities can't make full use of the positive impact of other cities' development,which means the level of regional specialization needs to be improved and the spatial structure of economic development needs to be further optimized within Pearl River Delta city group. The policy implication of the above findings is to promote regional industrial division and industrial spatial structure adjustment in the Pearl River Delta city group,resulting in the construction of coordinated industrial development pattern of different cities interactive.
