当前，作为空港经济的核心载体，空港经济区与都市区其他区域相比，承接着更高强度投资，担负更重大发展任务，将研究视角从单纯的机场建设转向"机场- - 区域"统筹发展，探讨空港经济区产业结构与空间格局优化路径，有可能为地方发展空港经济寻求创新性突破点。基于国内外典型机场的空港经济发展历程，归纳空港经济特征类型及其阶段演化，提出空港经济类型与阶段判定标准；提出空港经济区范围界定方法，以长三角空港经济区为例，评估区内产业结构与空间格局演变历程，并判定所属空港经济类型与阶段；构建因素贡献作用的影响计量模型，评估影响产业结构、空间格局演变的各驱动要素及其作用差异；研究关键驱动要素增强路径，结合空港经济特征类型与阶段演化分析，明确空港经济区产业结构优化、空间结构调整的具体路径，并提出相应措施。研究可以深化空港经济区的理论探索，也可为空港经济区产业结构与空间格局优化调控提供决策参考。

Comparing with metropolis's other areas,airport economic zone bears more intensively investment and More pressure.It's necessary to make research diversion from airport to the integrated area around the airport.The discussion on the industrial and spatial structure's path optimization inside the airport economic zone may found breakthrough for the development of chinese aerial economic.In the part of theory research,based on the literature collection of the typical airports's aerial economic development at home and abroad,we conclude the types and corresponding stage evolution of aerial economic;In the part of practical research,taking airports in YangZi-River Delta as example,firstly we proposed the scope determination method of the airport economic area,Secondly,we deduced the evolution of airport economic area's industrial struture and spatial structure.Based on this result, the aerial economic's types and stage of empirical airports will be judged;Thirdly,we established the theorial model of driving factors,assessing their different contribution;Forth,after the identification of key driving factors,we make clear of the path optimization of industrial development and spatial form,and the Institutional arrangement will be proposed further.This research will deepen the theoretical exploration of airport economic zone,on the other hand,it can also provide reference and classified guidance for the path optimization of industrial development and spatial form of YangZi-River Delta's airport economic zones.
