Urban greening: A new paradox of economic or social sustainability?

Cities globally have incorporated sustainable development into their planning, and led the way in responding to the world’s ecological crisis by “going green”. Urban green space accessibility is considered as the key to urban sustainability progress, not only environmentally, but also economically and socially. However, previous research rarely considers the latter two dimensions together. This study therefore joins the sustainability discussion from a new perspective, in particular the debate concerning the value of urban green spaces and whether and how they contribute to the variegated sustainability agenda? Based on data for 76,595 residential housing units in New York City, measuring the economic gains and equity losses from current urban green space accessibility reveals a paradox in sustainable development where the economic and social benefits of urban green space accessibility are seldom compatible, tending to involve a trade-off of some kind. In response, it is proposed that the spatial patterns of land use can represent a step towards multifaceted aspects of sustainability, with the provision of numerous small green areas that are “affordable and accessible” throughout the city being a more appropriate policy agenda than a few vast parks. Such a policy approach, it is argued, will provide a ‘win-win’ situation in terms of simultaneously contributing to both economic prosperity and the social justice of sustainability. This research also provided evidence for the institutional-driven countries such as China on how to learn from western experiences on planning land use patterns that are sustainable for individuals.     

地方金融发展能够影响FDI的区位选择吗?——一个基于城市商业银行设立的准自然实验

本文以城市商业银行的设立为自然实验,结合1990-2015年中国295个地级市数据以及成立的184家城市商业银行,运用双重差分方法系统考察了地方金融机构对FDI区位选择的影响。研究表明,城市商业银行的成立显著促进了城市FDI的流入;经过一系列稳健性检验和进行倾向得分匹配(PSM)估计之后,这一结论依然成立。结合企业数据证实城商行的设立提升了企业从银行获得贷款的可能性,能够通过缓解企业融资约束而影响FDI的区位分布。对城商行兼并和异地扩张行为的进一步分析表明:城商行经营规模的扩张,无论是对属地还是异地城市FDI的促进作用均不明显,而城商行资金规模的扩张对FDI有明显促进作用。这些发现将为我国完善金融体系和升级银行业结构、吸引FDI促进区域经济协调发展提供理论和经验支持。

An empirical Coasian study on the socio-economic profiles of two politically sensitive informal settlements: Kowloon Walled City and Rennie’s Mill

Informed by the “corollary of Coase Theorem” (Lai and Hung, 2008; Lai et al., 2007), for a better understanding of the self-help post-war development of two politically sensitive and vanished places in Hong Kong, the so-called “Kowloon Walled City” (Lai, 2016; Lai and Chua, 2017; Lau et al., 2018) and Rennie’s Mill (Lan, 2006), which have attracted academic interest but remained under-researched in terms of empirical scrutiny, this study:

• •Identify and compare their institutional arrangements by archival research;
• •identify and compare their development outcomes, as measured by census and other official data including mapping and photographic information, supplemented by published oral history of witnesses; and
• •establish and discuss the relationship between the differences in institutional arrangements and development outcomes in terms of a landlord-tenant analogy.

生态体验景观感知测评

生态体验景观属性是景观行动者—网络空间过程的表现,是生态体验过程价值实现的重要基础。文章以辽宁丹东的乡镇为例,采用结构方程模型验证了生态体验景观中乡镇生活、生态环境、休闲体验及产业发展等网络行动者属性的结构关系。在模型验证过程中,运用SPSS11.0及AMOS6.0软件测试景观网络行动者的结构关系模型及相互作用的路径系数;拟合度检验表明,结构方程模型具有较高的可靠性。     

后农业税时代河西走廊农户农地流转意愿及其影响因素分析——以张掖市为例

以河西走廊张掖市农户调查为例,采用Logistic模型对取消农业税后农户农地流转的意愿及其影响因素进行定量分析。研究表明：农地流转交易价格是影响农户农地流转的主要因素;家庭非农收入比例也对农户农地流转有较显著的影响作用;农业补贴额作用着农户农地流转;＂农户对农业税费减免政策的效应感知＂在一定程度上也影响农户农地流转。最后,提出了相关的政策建议。
