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。
From the point of view of the space balance between income growth and ecological improvement, the space imbalance in regional development does not match the space development status with its regional supply capacity, and the economic and social activities in the space do not carry out regional division of labor according to the comparative advantages of development and supply. When the scale and extent of regional development exceeds its possible supply capacity, it is considered over-developed; if insufficient utilization capacity is provided, it is underdevelopment. Taking the units of Jiangsu Province (county-level cities) as an example, the relationship between the intensity of development and the eco-importance index, environmental sensitivity index, scale concentration index, resource guarantee index and transportation economy index, The state of spatial imbalance can be judged and evaluated. At the same time, the imperfect price environment of resources and environment, the unreasonable orientation of government regulation and control elements, and the development-oriented fiscal, taxation and performance appraisal system are the institutional causes of the space imbalance.
