摘要:: 托育服务是生育支持政策体系的有力支撑. 对托育机构空间分布特征进行科学评价是合理配置托育服务资源的前提. 本文运用核密度分析法,研究成都市托育机构空间分布特征,应用高斯两步移动搜索法测算成都市托育机构的空间可达性,并重点分析20 min单一有效服务阈值和按托育机构规模划分的3级有效服务阈值. 研究结果显示:(1)成都市托育机构总体呈现中心城区集中、郊区新城分散的特征.(2)不同性质托育机构空间布局存在较大差异,中心城区非普惠性托育机构比例较高,郊区新城不同性质托育机构较均衡.(3)成都市中西部托育机构可达性优于东部,按规模划分3级有效服务阈值评价成都市托育机构空间可达性更为合理.

Abstract:: Childcare service is a strong support for the policy system of childbearing support. Scientific evaluation of the spatial distribution characteristics of childcare institutions is the premise for rational allocation of childcare service resources. In this paper,the kernel density analysis method is used to study the spatial distribution characteristics of childcare institutions in Chengdu,and the Gaussion two-step floating catchment area method is used to measure the spatial accessibility of childcare institutions in Chengdu. The focus is on the analysis of the single effective service threshold of 20-min and the three-tier effective service threshold divided by the size of childcare institutions. The results show that:(1)Childcare institutions in Chengdu generally show a distribution pattern of more in central cities and less in suburban new towns.(2)There are large differences in the spatial layout of childcare institutions of different natures, with a higher proportion of non-universalized childcare institutions in central city and a more balanced mix of childcare institutions of different natures in suburban new towns.(3)The accessibility of childcare institutions in the central and western regions of Chengdu is better than that in the east. It is more reasonable to evaluate the spatial accessibility of childcare institutions in Chengdu according to the three-tier effective service thresholds of scale.
