美国城市示范运动及其启示研究

在当代世界各国的城市化进程中,城市的更新改造和发展以及相关问题和矛盾的解决都是要面临的重要课题。示范城市运动是美国大规模城市更新运动的重要阶段,也是轰轰烈烈的"伟大社会"改革中后期重要的战略转移。本文选取该项运动为研究主题,回顾了其发生背景、发展过程,分析了其正反两方面的经验,以期为中国在进入改革开放关键时期构建和谐社会进程中更好地解决城市问题提供一个有价值的参照。     

中国重点城市入境旅游空间关联网络特征及优化

基于社会网络分析方法论视角,研究了中国12个重点城市入境旅游空间网络的节点结构特征和整体结构特征,并提出了旅游空间网络结构优化相关策略。结果发现:(1)重点城市入境旅游网络节点间共有46对旅游流联系,每个节点平均与其它3.83个节点存在着旅游流集聚和扩散联系,且充当旅游网络中介者角色的平均次数为8.25次;(2)北京和上海在入境旅游空间网络中居核心地位,西安、广州和杭州居次核心,其余城市的网络地位较低;(3)重点城市入境旅游的整体网络密度较低,不均衡性较明显。最后,提出优化重点城市入境旅游网络结构的相关策略。     

城市群时代中心城市的影响腹地界定研究——以济南市为例

进入21世纪,我国进入城市群快速发展时期,而中心城市的辐射和带动是城市群形成发展的重要基础。本文以济南市为例,通过构建多指标体系,在测算城市中心性强度值的基础上,利用扩展断裂点模型在GIS软件支持下勾勒济南在区外、区内两个层次的影响腹地范围。研究表明:受不同城市作用力影响,济南在区外城市间的影响腹地范围基本吻合山东省西部行政边界,与当前济南都市圈的范围基本一致;而区内腹地范围明显大于济南行政区划,形成了中心城市的高地效应。结合研究成果,对济南城市发展提出诸如合理调整行政区划、改善基础设施和加强都市圈建设等发展建议。     

中国西部城市居民时空间行为特征研究——以西宁市为例

时空间行为研究为透视中国城市转型与发展提供了重要视角,但已有研究对中国西部城市关注较少、未能形成反映西部城市特色的结论。选取西宁市作为案例,基于2013年居民时空间行为调查数据及城市设施分布数据,分析居民时间利用、时空路径等时空行为特征及其与城市设施分布的匹配关系,以此补充微观行为视角下的中国西部城市研究,为中国城市时空行为方法论提供西部城市的验证。主要结论包括：①相比于东部城市,西宁市存在工作活动比例低、平均时长短,早通勤时间延后,午休返家,时间安排灵活等特点; ②西宁市与周边地区间存在具有高原地区特色的跨城市通勤和休闲行为; ③居民活动分布与城市设施布局存在一定的空间错位。     

城中村外来人口的购房意愿研究——以深圳为例

本文以快速城市化的典型地区深圳作为研究区域,以居住在城中村的外来人口作为研究对象,调查其居住现状以及购房意愿,并分析其购房意愿的影响因素。分析发现,通过影响住房改善需求、未来发展规划、购房能力等,户主年龄、户主学历、住深时间、家庭收入、现住房的租金以及满意度、户主户口以及留深发展意愿对城中村外来人口家庭购房意愿有着显著的影响。     

Urban growth drivers in a Europe of sticky people and implicit boundaries

We investigate urban GDP per capita growth across the EU12 usingdata for functionally defined cities—rather than administrativeregions. We test hypotheses on the role of human capital, EUintegration and fragmentation of urban government and explorespatial dependence and mechanisms of spatial interaction. Resultsare acceptable on standard econometric tests without measuresof spatial interaction but there is spatial dependence. If variablesreflecting spatial adjustment are included, they are statisticallysignificant and eliminate spatial dependence. Not only do theresults now provide consistent estimates of parameters, butthey also support relevant theoretical insights and show nationalborders are still significant barriers to economic adjustment.People in Europe are sticky so it is unreasonable to assumespatial disparities will disappear. Our findings also implythat cities in Europe form national rather than a single continentalsystem.     

20世纪60年代初国家财政支援农业的历史考察

由于"左"的错误和自然灾害,中国在1959～1961年出现了三年经济困难,当时最突出的问题是农业生产遭遇严重挫折,粮食极度短缺。为加快农业生产的恢复,20世纪60年代初,国家制定了"吃饭第一"的方针,要求各行各业支援农业。利用财政手段增加对农业的投入是贯彻这一方针的重要举措。国家财政支援农业的措施主要有两方面:一是减少提取农业剩余;二是直接增加对农业和农村的财政投入。

INTERGENERATIONAL TIME AND MONETARY SUPPORT AMONG URBAN INDIAN FAMILIES

Intra-household time transfer is an important intergenerational support, less emphasised but more prominent than monetary transfers in the Indian family system. This paper attempts to study, empirically, the nature and pattern of time transfers between co-residing and non-co-residing parents and their adult married children in an urban setting in India. From the analysis of 673 representative sampled households, we have found that reciprocative time transfers between adult children and their parents constitute a central feature of the intergenerational support system, regardless of co-residency status. Significant correlates of time transfers to elderly parents are age, presence of other siblings in the household, headship status, and monetary support received from and made to parents. However, there is no evidence of inter-substitution between time and money between the two generations, i.e. married adult children and their parents. Time support is more frequent and intense when parents reside in the same city, whereas monetary transfers dominate when parents reside in a distant city or village.     

The Effects of Inter-generational Support on the Mortality of Older People in Rural China

As inter-generational support is the primary source of support for the Chinese elderly in rural areas, such support is likely to affect their physical and psychological health. This paper investigates the effects of four types of inter-generational support on the mortality risk of the elderly in Anhui Province. Results showed that mortality risk was influenced significantly only by receiving household support. Financial support and personal care had no effect. Results also indicated that household and emotional support were effective in reducing mortality when delivered at closer proximity, suggesting that quality of support may be enhanced by co-residence and ready access to children. Conclusions about the health benefits of tangible forms of support need to be tempered by an understanding that poor health predisposes inter-generational co-residence, and that the quality of household assistance and emotional support may be sensitive to the geographic distance between older parents and their adult children in rural China.
