China's rapid development and urbanization over the past 30 years have caused large numbers of rural residents to migrate to urban areas in search of work. This has created a generation of children who remain behind in rural areas when their parents migrate for work. Previous research has found mixed impacts of parental migration on the educational achievement of left‐behind children (LBC), perhaps because of methodological deficiencies and lack of recognition of the heterogeneity of this population of children. Our study attempts to examine the impact of six types of parental migration on the academic achievement of a rural junior high school sample. Our study uses a panel of 7148 junior high school students to implement a difference‐in‐difference analysis and finds that parental migration has a negative and significant impact on the academic achievement of junior high school students. Our study suggests that the Chinese Government should implement measures to dismantle barriers to the human capital accumulation of LBC to ensure sustainable economic growth and human capital development in China. 相似文献

Rural residential land transition (RRLT) dominates rural land use transition. Therefore, analysing the laws of transition and differentiation of land use is not only the basis for the differential management of rural residential areas but key to the sustainable use of rural land. This study constructs a conceptual model of RRLT using multi-period remote sensing monitoring data based on a comprehensive index method, ArcGIS, and FRAGSTATS landscape pattern analysis, among others. It also analyses the characteristics of the transition extent, transition trend, transition morphology, and transition intensity of rural residential land in the Beijing-Tianjin-Hebei (BTH) region from 1980 to 2018. The results show that, from a vertical comparison of long time series, the transition extent is characterised by a process of ‘slow growth—expanding start—fast expansion—slowing down’; the transition trend is characterised by an increase in the amount of cultivated land occupied by rural residential land, followed by a large number of rural residential land is reclaimed as cultivated land; the transition morphology is characterised by an increase in mean patch size and degree of irregularity, as well as aggregation; and the transition intensity is characterised by fluctuations in the process of ‘small-scale reduction—small-scale growth—substantial growth—small-scale growth and reduction’. A horizontal comparison of counties in the BTH region reveals a long-lasting and active growth trend in transition extent and transition intensity in the Beijing-Tianjin region, and a gradually slowing trend in the areas around the region. The transition morphology features of the northwest Hebei region are more prominent, and show that the scale of rural settlements is small, the plaques fragmented and irregular, and the layout more scattered. The BTH region should formulate a differentiated transition direction for rural residential areas based on the different functional areas, and play into the agglomeration, scale, and synergy effects of urban agglomerations. It should also coordinate and improve the human–land relationship in rural areas, and construct an orderly and densely distributed pattern of urban and rural spatial development with a reasonable layout and complementary functions. 相似文献

深度休闲对优化苏南地区休闲产业建设,进一步提升居民休闲生活质量有重要影响。文章通过问卷调查的方式收集苏南地区城市居民深度休闲行为的数据,研究苏南地区城市居民深度休闲行为特征及深度休闲对主观幸福感的影响。结果发现:(1)苏南地区城市居民进行深度休闲活动的场所主要为户外;(2)闲暇时间不足是限制苏南地区城市居民进行深度休闲活动的主要因素;(3)苏南地区城市居民的深度休闲活动总体程度不高,愿意在深度休闲活动上投入大量时间和金钱的人更是少数;(4)苏南地区城市居民从事深度休闲活动产生的强烈认同感和坚持不懈的毅力对主观幸福感有着显著的积极影响。 相似文献

The purpose of this article is to investigate whether place is emerging in practice as a critical dimension in the development of Canadian rural regions. Recently, Jones and Paasi set regional researchers the task of better understanding how regions ‘become'. In researching this question, we are particularly interested in the definition and expression of place‐based identity as a mobilizing force for regionalism. Our findings suggest that, while identity plays a critical role in fostering regional development processes, it is either too emergent or actively resisted within our research sites to be a significant force for place‐based regional development. 相似文献

目前,农村金融消费者权益保护工作力量薄弱,自然灾害对农村金融消费者影响较大;同时,金融产品设计对农村金融消费者权益保护考虑不足。为保护农村金融消费者权益,并最大限度地规避自然灾害给农户带来的经济损失,应循序渐进、阶段性地推动金融消费立法,完善农村金融服务体系,构建农村金融消费者自然灾害权益保护机制,开展针对农村金融消费者的常态化宣传教育活动。 相似文献

我国城乡低保标准现状如何,为社会各界广泛关注。有人认为目前的城乡低保标准偏高,有人认为目前的城乡低保标准偏低,存在一定争议。对各省份2010年到2012年的城乡低保标准进行量化分析表明,我国城乡最低生活保障标准的替代率呈总体上升趋势,大致在合理区间;但城乡之间、地区之间的差距较大,不平衡问题突出,形势不容乐观。 相似文献
