郑州航空港临空经济区产业聚集效应分析

Analyze the Industrial Agglomeration Effect of Zhengzhou Airport Economic Zone

利用固定替代生产函数(CES),测算了郑州航空港临空经济区的产业聚集水平,并从内部聚集经济、布局集聚经济和城市聚集经济三个方面对郑州航空港临空经济区的产业聚集效应进行因素分解。研究结果表明:郑州航空港临空经济区的产业聚集效应呈现增长趋势,产业聚集效应开始显现出来。内部聚集经济、布局集聚经济和城市聚集经济系数均为正值,说明郑州航空港临空经济区产业结构较为合理,规模经济凸显,形成了合理的产业链条,提高了产业聚集水平。

By using fixed substitution production function （CES）, this paper calculates the industrial agglomeration level of Zhengzhou Airport Economic Zone, and analyzes the industrial agglomeration effect of Zhengzhou Airport Economic Zone from three aspects, namely internal agglomeration economy, layout agglomeration economy and urban agglomeration economy. The results show that： Zhengzhou Airport Economic Zone Industrial agglomeration effect presents growth trend, indicating the emergence of industrial agglomeration effect. The coefficient of internal agglomeration economy, layout agglomeration economy and urban agglomeration economy are all positive, indicating the industrial structure of Zhengzhou Airport Economic Zone is reasonable, the scale economy is prominent. We can say that a reasonable industrial chain is formed, and the level of industrial agglomeration is improved.
