中文摘要：

从收入增长和生态改善的空间均衡角度来看,区域发展空间失衡是空间开发状态与其区位供给能力不相匹配,空间的经济社会活动没有按照开发供给的比较优势进行地区分工配置。当区域开发规模及程度超过其可能的供给容量视为开发过度;若没有充分利用供给容量,则为开发不足。以江苏省县（县级市）单元为例,采用开发强度与反映空间供给能力的生态重要性指数、环境敏感性指数、规模集聚指数、资源保障指数、运输经济指数的相关关系以及协调度,可以判断和评价空间失衡的状态。同时,资源环境价格市场不完善,政府调控要素导向不合理以及开发导向的财税和政绩考核体系等安排,都是导致空间失衡的制度原因。

英文摘要：

Regional spatial imbalance is the result of the mismatch between the developing state and the location supply capacity in the view of income increase and ecological improvement.This is because when we make regional resources division and allocation,the regional socio-economic development is lack of consideration of the exploitation-supply comparative advantage.When the scale and degree of regional development surpasses the possible supply capacity,it would be over development,otherwise it is insufficient development.Taking counties in Jiangsu as the study units,exploitation intensity and other indexes reflecting the spatial supply capacity are applied to determine and assess the spatial imbalanced state,such as ecological significant index,environmental sensitive index,scale aggregation index,resource insurance index and transport economic index.In the meantime,the imperfect price market of resource environment,the unreasonable administrative allocation,and the development-oriented finance,tax,cadre assessing systems are all the institutional reasons for spatial imbalance.
