统筹城乡的建设用地空间重构机制与对策研究

统筹城乡发展要求重构建设用地空间。分析了我国土地政策促进城乡统筹的现实困境,表现为城乡用地供需错位、土地要素缺乏流动性、置换指标区际交易机制不健全、收益共享机制不完善等;以此为基础,从农村建设用地整理模式转换、置换指标跨县区流转、土地增值收益共享、规划引导4个方面构建了统筹城乡的建设用地空间重构机制;并提出要加强土地政策与相关政策的衔接,强化监管及保障体系建设,以充分发挥土地政策的宏观调控作用。     

自然生态空间用途管制理论分析及管制策略研究

研究目的:深入探讨自然生态空间用途管制作用机理及管制策略,助力完善国土空间用途管制制度。研究方法:文献分析法、归纳演绎法。研究结果:(1)模型能够较好反映自然生态空间与城镇空间和农业空间的联动效应;(2)阐明了自然生态空间用途管制行为主体、空间利用行为主体、空间利用行为以及用途管制客体之间的关系及管制作用机理;(3)明确"生态底线"导向的直接用途管制与"精明增长"导向的间接用途管制方式并行的管制策略。研究结论:建议完善国土空间规划体系,建立自然生态空间管制实施机制,加强自然生态空间用途管制要与其他自然资源管理改革制度的统一设计,强化实施自然生态空间管控质量监测评估。     

Is more better? The relationship between meeting space capacity and hotel operating performance

This study examines the effect of meeting space capacity on hotel operating performance. We use Resource-Based View (RBV) of the firm as the theoretical foundation. We employ a national-level dataset with more than 20,000 hotels in the United States for the 2007–2012 period. We find that meeting space has a non-linear effect on hotel operating performance. That is, at low levels of meeting space, meeting space capacity is negatively related to hotel operating performance. At high levels of meeting space, meeting space capacity has a positive influence on operating performance. These findings provide insights for hotel owners, developers and practitioners in planning hotel meeting space capacity.     

南京市休闲农业空间差异及其社会经济影响因素分析

[目的]休闲农业在促进产业融合、带动过农业、农村发展方面发挥着重要作用,分析其空间分布特征及其社会经济影响因素,为休闲农业的健康可持续发展提供一定参考。[方法]文章以南京市为例,通过文献查阅法了解南京市休闲农业的资料、相关研究成果,结合实地调查法确保南京市休闲农业景点的真实性,采用空间结构分析法分析休闲农业空间分布差异,相关分析法分析其影响因素。[结果]南京市6个区的最临近指数均小于1,空间分布呈凝聚型,其中浦口区的分布密度最大,为0.035个/千km~2。休闲农业分布与地区GDP、农业产值、旅游发展水平显著相关,与产业结构、城镇和农村居民消费水平相关,但不显著,说明目前南京市第一、二、三产业融合有待进一步加强,休闲农业产品仍有提升空间。[结论]南京市休闲农业发展受社会经济发展的影响,因此需要基于休闲农业资源,差异化发展,同时协调发展休闲农业服务供应链,促进产业融合,完善休闲农业相关政策,耦合侧供给改革共同发展。     

The Politics of Property in Planning: Hezbollah's Reconstruction of Haret Hreik (Beirut,Lebanon) as Case Study

This research looks at post‐2006‐war reconstruction of the southern suburbs of Beirut under the auspices of Hezbollah (the Islamic resistance movement in Lebanon). The project was widely acclaimed as an alternative to current neoliberal planning practices in the Middle East and beyond. Based on a critical reading of the conception of property issues in this planning project, the article argues that this reconstruction presents a new geometry or alternative to the mainstream configuration of neoliberal urbanism, rather than a departure from its precepts. The reason for this is that the adopted language of property corresponds closely with the conception of property advocated by neoliberal planning, one that enshrines private, individual ownership as sacred and desirable and that works to strengthen its model in the city. I further argue that the ‘neoliberal planning regime’ within which Hezbollah's urban intervention occurs is not accidental; rather, it is necessary for the party's control of this space's future and for consolidating its territory in the city. It is hence expected that Hezbollah's planning in the city will produce the same decried effects as neoliberal planning elsewhere in the city rather than usher an innovative, progressive model of planning.     

CONVEX RISK MEASURES FOR GOOD DEAL BOUNDS

We study convex risk measures describing the upper and lower bounds of a good deal bound, which is a subinterval of a no‐arbitrage pricing bound. We call such a convex risk measure a good deal valuation and give a set of equivalent conditions for its existence in terms of market. A good deal valuation is characterized by several equivalent properties and in particular, we see that a convex risk measure is a good deal valuation only if it is given as a risk indifference price. An application to shortfall risk measure is given. In addition, we show that the no‐free‐lunch (NFL) condition is equivalent to the existence of a relevant convex risk measure, which is a good deal valuation. The relevance turns out to be a condition for a good deal valuation to be reasonable. Further, we investigate conditions under which any good deal valuation is relevant.     

Pareto-undominated and socially-maximal equilibria in non-atomic games

This paper makes the observation that a finite Bayesian game with diffused and disparate private information can be conceived of as a large game with a non-atomic continuum of players. By using this observation as its methodological point of departure, it shows that (i) a Bayes–Nash equilibrium (BNE) exists in a finite Bayesian game with private information if and only if a Nash equilibrium exists in the induced large game, and (ii) both Pareto-undominated and socially-maximal BNE exist in finite Bayesian games with private information. In particular, it shows these results to be a direct consequence of results for a version of a large game re-modeled for situations where different players may have different action sets.     

A non-cooperative approach to the ordinal Shapley–Shubik rule

In bargaining problems, a rule satisfies ordinal invariance if it does not depend on order-preserving transformations of the agents’ utilities. In this paper, a non-cooperative game for three agents, based on bilateral offers, is presented. The ordinal Shapley–Shubik rule arises in subgame perfect equilibrium as the agents have more time to reach an agreement.     

Towards a spatial perspective: An integrative review of research on organisational space

Although the notion of space has gained considerable attention in organisation studies, it remains vague, and the respective literature is fragmented. In this paper, we review the empirical literature on organisational space with the aim of synthesising the findings of existing research and thereby facilitating the development of cumulative knowledge in this field. We highlight three dominant concepts that define space: boundaries, distance and movement. Furthermore, we identify four major spatial themes: the distribution of positions in space, the isolation of space, the differentiation of spaces and the intersection of distinct spaces. On that basis, we develop a comprehensive research framework and propose an agenda for future research on organisations from a spatial perspective.     

市域城镇体系空间布局研究——以河南平顶山为例

城镇体系的空间结构研究是人文地理学研究的重要方向。城镇体系的空间结构是否合理,对区域经济的发展有一定作用。文章采用定性分析与定量分析相结合的研究方法,对平顶山市域城镇体系规模等级、地域空间结构、市域经济发展水平等现状进行分析,通过运用断裂点公式对平顶山市域中心城市辐射影响范围进行定量计算,剖析平顶山市域城镇体系存在如下问题:城镇体系人口规模等级差异大,城镇化率基础好于全省平均水平,城镇化水平发展不平衡,城镇体系空间结构状态非均衡等。根据研究区域情况,对平顶山市域城镇体系进行布局构想,即打造叶平宝鲁一体化核心区为引领,加强3个卫星城市的发展为带动,做好小城镇的生态建设,完善市域交通网络建设,推进产业集聚区的建设,建立起一个等级清晰、核心突出、职能明确的"一心三卫三层"网络型城镇体系。
