“大都市阴影区”嘉兴市的形成机制解析——兼与苏州市的发展差异研究

METROPOLITAN SHADOW-ANALYZE OF THE FOUNDATION OF JIAXING AND THE EVOLUTIONARY DIVERSITY BETWEEN SUZHOU AND JIANGSU

本文以上海大都市周边的苏州和嘉兴两个城市的发展为例,通过对比其差异的发展现状和轨迹,分析了"大都市阴影区"的形成机制,并得出以下结论并对相应的理论模型进行了修正:①在我国,国家或地方的"政策偏向"是影响大都市发展以及"大都市阴影区"形成的最重要的要素;②"大都市阴影区"的形成,更多是由于外围地区受到相关政策等因素影响而导致了自身发展不充分。在自身发展不充分的情况下,区位越是接近中心城市,越会导致中心城市对其发展要素的吸引和袭夺;③中心城市对外围地区的要素袭夺是可以改变的,外围地区应通过自身的充分发展而削减其负面效应;④消减"大都市阴影区"效应,不仅需要中心城市的集聚与扩散机制的优化调控,更需要处于阴影区效应中的地区采取积极主动的策略。

Locational factors of distance-limited space play an important and complicated role in the evolu- tion process of contemporary urban areas and extended metropolitan regions. Since region＇ s uneven develop- ment, even though some areas have the same geographical conditions, they still have significant economical gap. Some areas become parts of the centre metropolis because they have full development with the elements diffusion from centre metropolis. But the some areas become the metropolitan shadow because they lose their economical elements like surplus labors. Through examining the economical development difference between Suzhou and Jiaxing, this paper indicates that Jiaxing is the metropolitan shadow area of Shanghai, and also it analyzes the formation mechanism of metropolitan shadow. We conclude that： （1）in China, region- al or local policy bias is the main reason of metropolitan shadow formation; （2）The effects on peripheral ar- eas of centre city in metropolitan also depend on the peripheral areas themselves, especially by regional and local policies; （3）The attraction of centre metropolitan can be changed if the areas around it improve their economy a lot by many measures; （4）To reduce the effects of metropolitan shadow, it need the centre city op- timize its regulation as well as the shadow areas adopt positive strategies.
