摘 要:基于10 946条工商企业数据对1999~2013年长三角5个主要空港经济区产业结构与空间分异展开实证分析,结论如下:(1)长三角主要空港经济区的临空产业体系已经初步形成,与非临空产业相比,集聚优势不明显,临空产业占比基本稳定在25%以下,强指向行业有待进一步发育,空港开发还处于总量扩张阶段;(2)各类产业的集聚空间各异,临空企业和非临空企业从圈层区分度较低,分别朝向心、离心布局演进,目前长三角空港经济区的临空企业仅在3 min车程范围内具备优势,向外则以非临空企业为主;(3)各类产业外推速度各异,受服务业选址落户自由灵活、临空区位指向等影响,服务业、无临空产业向外扩张明显,而制造业、临空产业布局空间较稳定;(4)空间分异度取决于全区发育水平,长三角较为成熟的空港经济区的制造业、服务业、临空产业等各类产业之间均已经形成圈层分化,而处于成长或者起步阶段的空港经济区产业混杂布局特征较明显。临空指向、空港区位和园区可建设空间等也是重要的空间分异影响要素。Based on the business data between 1999-2013, this paper analyzed the industrial adjustment and spatial differentiation of the main airport economic zones in the Yangtze River Delta, Conclusions are as follows: 1) With the development of airport economic zones, both hub-orientation industry and none hub-orientation industry have a rapid growth, but percentage of the hub-orientation industry are lower than 25%, the airport economic zones in Yangtze River Delta is still at the stage of quantity expanding. 2) The concentration space of industries are different, with the development of airport economic zones, the hub-orientation industry had radial clusters while the none hub-orientation industry had the centrifugal layout.Now the hub-orientation industry in the Yangtze River Delta only has the concentration advantage in the three minutes time circle. 3) Different industries had different expanding speed, influenced by the flexible location and specificity of none hub-orientation, service industry and none hub-orientation industry expanded rapidly, while the manufacture industry and the hub-orientation industry's concentration space is stable. 4) The comprehensive development level of airport economic zones determines whether the circles' differentiation is clear or not. A deeper industrial analysis shows that it is easier for relatively mature airport economic zone to form a industrial distribution pattern,while in the immature airport economic zone, industry with different hub-orientation has mixed layout.With the exception of maturity level, the hub-orientation, airport's location and the construction land space of airport economic zones also have strong influence on the spatial differentiation in the airport economic zone.
