基于生态位视角的山区城乡居民点的空间重构与土地整治（英文）

With the socio-economic development associated with urbanization, the urban-rural relationship has changed across the world. In China, due to the urban-rural dual structure, these changes turn out to be more complicated. Spatial restructuring are suggested as the main strategies and spatial supporting platforms for urban-rural development. However, the theory still lacks solid methodology and support from systematic empirical studies. This study seeks an adequate scientific methodology and discusses the difference of urban-rural transformation in plains and mountainous areas. A case in Shanghang County, China, demonstrates: 1) The compound ecological niche model can be a suitable approach in urban-rural restructuring, especially in mountainous areas. 2) The urban-rural development area with highly inappropriate, slightly appropriate, moderately appropriate, and highly appropriate areas are 1273.2 km2(44.69%); 906.1 km2(31.80%); 509.4 km2(17.88%); and 160.1 km2(5.62%), respectively. 3) The "deserting villages" in mountainous areas play positive synergistic roles in urbanization, in contrast to the "hollowing villages" common in plain areas. 4) The central town-village will become the most important settlement in mountainous areas. Therefore, we suggest more attention should be paid to environmental capacity in the construction of central town-villages. This study significantly extends the understanding of "hollowing village" theory and regional planning.     

基于面板数据的中国R&D投入对城镇化影响分析

利用中国30个省区2002-2012年R&D投入和城镇化水平的面板数据,通过单位根检验、协整性检验和面板数据模型,探讨中国R&D投入对地区城镇化发展水平的影响。结果表明：①中国各省区城镇化水平与R&D投入存在长期稳定关系,但城镇化水平的科技支撑基础仍处于较低水平,并且不同省区的R&D投入产出存在较大差异。②总体上看来,R&D人员投入产出弹性高于R&D经费投入,说明城镇化对R&D人员投入的依赖性更大。③R&D投入对城镇化的作用与其所处的城镇化阶段有关,同时,R&D投入与城镇化的协调度也是影响R&D投入产出的关键因素。④误差修正模型结果表明,R&D短期投入对城镇化的影响存在一定的滞后效应。     

福建省乡村发展与农村经济聚集耦合分析

中国的城镇化进程对农村产生深远的影响。本研究关注快速城镇化背景下的沿海农村发展和趋势,以福建省为例进行实证研究,结果表明,福建省的乡村性从2000年到2010年略有降低,并呈现从东南到西北增加的空间格局。本研究同时构建了区位商及其变化趋势的综合指标辨析农村经济聚集区及其动态发展特征。农村经济呈现明显的区位特征和聚集特征,非农产业聚集区出现在乡村性较弱但经济最为发达的东南地区。福建省西部和北部农村出现了非农产业新兴区和农业聚集区,区域内农业优势变化的驱动力较强。非农产业成熟区和新兴区是福建省的主体区域。传统农业区的空间比例最小,且呈现稳态的发展轨迹,转变的驱动力较小。乡村性与区位商总体上具有较好的正相关性。但是不同农村经济聚集区的乡村性和区位商的耦合程度具有多样性。农村的非农经济得到长足发展,出现新的农村类型。本文最后讨论了福建省县域尺度的农村发展和趋势,并对村镇这种新的农村形态的形成与聚集区域进行了探索性的研究,明确了不同形态的农村的发展区域,为新型城镇化建设和新农村建设两大国家战略的实现提供科学的依据。
