Social capital and community preparation for urban flooding in China

Social capital can enhance community resilience to environmental change. Productive and trusted relations among social actors and effectual social norms can help local residents share resources, information and risks. The main objective of our study is to understand the ways in which social attributes and risk considerations influence adoption of resilient economic measures by individuals for reducing potential losses due to catastrophic rainstorm and flooding. This article provides evidence from China on how social capital contributes to anticipatory adaptation to environmental change. The inquiry is based on structured interviews with local residents of Tianjin, a flood-prone port city in China, and a standard regression analysis. Findings show that the intention to make preparation increases with the levels of social expectation, social relationship, and institutional trust. Perceived risk and damage experience, however, have no significant impacts. This suggests that building social capacity and trust will be more effective in enhancing community resilience than merely increasing awareness of hazard risks. We call for greater efforts on strengthening the capacity of formal and informal communal institutions. The structural changes required, however, are challenging.     

基于DEA和Malmquist的中国城市代谢效率研究

运用物质流、数据包络分析(DEA)及Malmquist指数对中国31个案例城市进行了城市代谢效率的研究。通过将城市代谢系统社会经济产出、环境非期望产出及水、电、化石能源、金属矿物、建筑材料、食物等投入部分纳入进DEA和Malmquist指数中,测得了案例城市的2000年、2010年代谢效率及变化趋势。研究结果发现,中国城市代谢系统效率总体相对较高,尤其是东中部地区城市的综合效率、纯技术效率和规模效率要高于西部地区城市,大城市的代谢综合效率高于巨型、超大和特大城市。2000~2010年,城市代谢综合效率、纯技术效率等所有效率指标的均值均呈现出下降趋势,但是中、西部地区城市的综合效率和纯技术效率却呈改善趋势,并且特大和超大城市的综合效率高于巨型城市。     

基于地理视角的智慧城市规划与建设的理论思考

智慧城市建设是推动城镇化发展的重要动力,其建设除了技术支撑之外,还应充分考虑信息技术对城市政府、企业和居民活动及其空间的影响。本文在对国内智慧城市建设现状与问题分析思考的基础上,认为智慧城市的出现是适应当前城市化战略转型、公共服务提升、社区发展和城市问题解决的必然趋势,从多源异构数据整合、信息系统和空间分析平台两个方面梳理智慧城市建设的关键技术,从流动空间以及新的人地关系、时空协调发展等方面提出智慧城市的理论支撑,并进一步明确地理学应对和研究重点。同时,提出基于城市地理研究的智慧城市规划与建设实践的主要方向,包括顶层设计、功能和空间布局、基础设施整合、城乡治理等内容。     

基于省会城市的中国体验性网络团购发展的空间格局与空间错位

体验性网络团购是一种消费者需要到店才能完成消费的特殊网络购物形式,因其服务范围的空间局限性,正在对消费地理格局产生不可忽视的影响。借助360团购导航网站,以中国30个省会城市(含直辖市)为研究对象,采用综合规模指数、发展水平指数、集中化指数、空间错位指数等指标,对中国体验性网络团购发展的空间格局与空间错位特征进行了实证研究。结果表明:1团购市场发展规模在中国省会城市的空间分配极不均衡,主要受东部发达城市的带动作用,同时也受西部地区部分内在增长极城市的驱动影响;2中国省会城市团购市场的发展主要处于"小规模—低水平"和"大规模—高水平"的两极化状态;3城市的经济发展水平是团购市场规模扩张的根本动力,城市的网络零售市场消费潜力规模以及互联网基础设施规模、互联网用户规模和发展水平也对团购市场规模有明显的驱动作用;4中国省会城市团购市场的发展规模在空间上与消费者的需求潜力的错位程度较低,与购买能力错位现象较明显,空间错位主要是由部分城市的团购市场规模发展过大或过小造成的。     

Networking,context and firm-level innovation: Cooperation through the regional filter in Norway

The paper assesses the role for innovation of one aspect which has been generally overlooked by evolutionary economic geography: context. It analyses how context shapes the impact of collaboration on firm-level innovation for 1604 firms located in the five largest city regions of Norway. Specifically, the analysis shows how the benefits to firms of collaborating within regional, national, and international innovation networks are affected by the knowledge endowments of the region within which the firm is located. Using a logit regression analysis, we find, first, that only national and international networking have a significant positive impact on the likelihood of innovation (the former only for process innovation), whereas the regional knowledge endowments have no direct effect. Second, regional cooperation is particularly effective in regions with high investments in R&D, whereas international cooperation is important in regions with an educated workforce – and regional and national collaboration may be ineffective in such cases. We conclude that, in the case of Norway, context is essential in determining the capacity of firms to set up networks and innovate. Regions with an educated workforce can use the resulting absorptive capacity to successfully assimilate knowledge being diffused through global pipelines from faraway places. However, this absorptive capacity is likely to be heavily filtered if regional firms mainly rely on internal connections within Norway.     

我国沿海城市应对气候变化的发展战略

我国沿海地区战略地位十分重要,并呈现“区域发展沿海化,沿海城市临海化”的趋势,但同时却面临着全球气候变化引起的海平面上升、极端气候灾害频发等诸多严峻挑战。为在战略层面解决我国向海发展的战略与全球气候变化的矛盾与冲突,文中提出了我国沿海城市应对气候变化的发展战略：确定了总体目标是建设适合我国国情的沿海气候弹性城市,提出了“规划引领、陆海统筹、主动适应、积极减排、适度冗余、增加弹性”的应对原则,明确了强化城市规划管控、控制空间发展方向、严控围填海造地、优化城市空间布局、提高规划设计标准、加强海岸防护设施、夯实城市基础设施和提升监测预警应急等8项重点任务。

中国城市(包括辖县)的工业职能分类——理论、方法和结果

在城市发展的经济基础理论的指导下,作者提出城市工业职能的概念包括城市的专业化部门、职能强度和职能规模三个要素。城市工业职能分类就是按照上述三要素的相似性和差异性对城市进行分类。本研究曾采用主因素分析、聚类分析和纳尔逊的统计分析等多种方法。最后以沃德误差法的聚类分析结果作为分类的基础,稍加修正,并以纳尔逊法分析结果作补充。中国1984年的295个城市被分成三个大类、十九个亚类和五十四个职能组。
