空间管治视角下京津冀协同发展类型区划

京津冀协同发展的核心是基于问题导向和底线思维,打破行政区划,在更大区域尺度上优化资源配置,实现区域整体发展目标。因此,从优化空间规划体系的高度,开展京津冀区域协同发展的类型区划和类型区管理,实现分区施策的精细化管治极为重要。本文首先立足于京津冀区域发展差异,利用空间属性双聚类的方法将京津冀划分为中部核心功能引领区、东部沿海重点发展区、南部门户功能拓展区、西部和北部生态涵养保护区等四大区域;然后以区县为最小分析单元,从现状开发强度、用地增量预测和生态保护责任等三大维度构建类型划分指标体系,并利用三维空间坐标划分方法将京津冀划分为五大类型区,即：城镇优化发展区、城镇重点拓展区、现代农业发展区、适度建设发展区和严格生态保护区;最后,在空间管治视角下提出京津冀区域分区管治与区域协同管理的建议。

Spatial development regionalization of the Beijing-Tianjin-Hebei region from the perspective of spatial governance

The core of collaborative development of the Beijing-Tianjin-Hebei region is problem-oriented, aiming at breaking the administrative boundaries and optimizing the allocation of resources on a larger regional scale, thus realizing the overall regional development goals. As a consequence, it is crucial to carry out spatial development regionalization and implement targeted local governance according to the needs of modernizing regional spatial governance system and from the perspective of improving the spatial planning system. On the basis of regional development differentiation, this study conducted cluster analysis based on spatial and attribute constraints to divide the Beijing-Tianjin-Hebei region into four subregions, that is, the central core function development region, eastern coastal key development region, southern gateway function development region, and northern and western ecological conservation region. This study further used districts and counties as the basic unit of analysis and constructed a classification index system at the micro spatial scale, considering the status quo of development intensity, urban construction land increment forecast, and ecological protection responsibility. The status quo of development intensity is composed of population density, construction density, input density, and output density. Ecological protection responsibility mainly incorporates restricted construction area and limited construction area. Urban construction land increment forecast is determined by elements including natural, socioeconomic, transportation, planning factors, and so on. With the aid of a three-dimensional coordinate classification method, the Beijing-Tianjin-Hebei region can be divided into five typological divisions at the district and county levels, namely, urban optimized development area, urban key development area, modern agriculture development area, limited and moderate development area, strict ecological reserve area. Corresponding to the above analysis, this article puts forward policy recommendations on spatial governance: (1) Emphasizing the fundamental role of the market in resource allocation and improved regional development; (2) Mediating the contradiction between development and protection, building up a mechanism of sharing benefits and the burden of risks.
