开放经济中的金融安全问题及其保障对策

在开放经济体系中，金融安全至关重要，它构成了产业安全的核心内容。一般认为，金融安全是指一国能够抵御内外冲击保持金融秩序和金融体系正常运行与发展的状态以反维持这种状态的能力和对这种状态与维持能力的信心与主观感觉，包括在这种状态和能力下所获得的政治、金融制度和体系的安全、金融财富的安全、金融机构的安全、金融发展的安全，对整体经济和政治安全起决定性作用的金融运行的安全等。发展中国家尤其应当重视金融安全问题，通过各种有效的措施积极防范和化解金融风险，保障金融安全。

基于虚实二重性分析的房地产理论重构

传统的仅从实体经济的角度来研究房地产的经济理论已经不能完全诠释当今房地产经济发展的现实。通过对房地产从虚拟经济角度进行分析,我们可以发现,房地产具有实体资产和虚拟资产二重属性。正是房地产的这种特性决定了房地产具有稳定经济的职能,对经济增长具有重要意义。因此,我们应该在房地产虚实二重性的基础上重构房地产经济理论。     

双支柱调控的金融稳定效应研究

本文基于全球42个主要经济体1991—2016年的面板数据,系统考察了双支柱政策框架的金融稳定效应。实证结果表明：（1）货币政策和宏观审慎政策在抑制家庭信贷增长上具有显著作用,双支柱政策在缓解金融风险顺周期性上具有显著的金融稳定效应;（2）盯住贷款的宏观审慎工具和针对借款人、贷款人的宏观审慎组合具有更为显著的金融稳定效应;（3）新兴经济体的货币政策在抑制家庭信贷扩张上的作用不显著,但其宏观审慎政策的金融稳定效应相较发达经济体更为显著,发达经济体双支柱政策的金融稳定效应总体显著,其中货币政策效应更为突出;（4）发达经济体的货币政策效应在下行周期优于上行周期,宏观审慎政策及其与货币政策的交互效应在上行周期优于下行周期;（5）只有个别宏观审慎工具会对失业率、消费和物价产生微弱的负效应。     

The Borda rule,Condorcet consistency and Condorcet stability

Summary. The Borda rule is known to be the least vulnerable scoring rule to Condorcet inconsistency, Saari (2000). Such inconsistency occurs when the Condorcet winner (the alternative which is preferred to any other alternative by a simple majority) is not selected by the Borda rule. This note exposes the relationship between the Borda rule and the Condorcet q-majority principle as well as the Condorcet q-majority voting rule. The main result establishes that the Borda rule is Condorcet q-majority consistent when where k is the number of alternatives. The second result establishes that is the minimal degree of majority decisiveness corresponding to the Borda rule under sincere voting. The same majority is required to ensure decisiveness under the Borda rule and to ensure that a q-rule (the generalized q-majority Condorcet rule) is a voting rule.

Candidate stability and nonbinary social choice

Summary. The requirement that a voting procedure be immune to the strategic withdrawal of a candidate for election can be formalized in different ways. Dutta, Jackson, and Le Breton (Econometrica, 2001) have recently shown that two formalizations of this candidate stability property are incompatible with some other desirable properties of voting procedures. This article shows that Grether and Plott's nonbinary generalization of Arrow's Theorem can be used to provide simple proofs of two of their impossibility theorems.

乡镇土地利用规划中农村居民点用地空间布局优化研究——以衡南县廖田镇为例

由于长期以来缺乏系统的规划,农村居民点用地呈现出数量多、分布零散、利用粗放等问题,对农民生活水平提高、农村经济和农业现代化发展形成了束缚。在新一轮土地利用总体规划背景下,亟需对其空间布局优化进行研究,以引导农村居民点用地的科学管理。在分析研究区农村居民点用地特点的基础上,从宏观上构建优化布局的四级等级体系,从微观上设计优化布局的三种模式:城乡融合型、中心村重构型和产业优先型。并在Mapgis软件支撑下,选择典型区域对农村居民点用地进行微观空间布局调整。

美国信用消费法律制度及其对中国的启示

美国作为世界上信用消费制度最发达的国家之一,其信用消费立法一直备受关注。2009年的《金融改革方案》虽然确立了消费者保护的目标,但也给经济发展带来了更大的不确定性。在信用消费立法联邦化的趋势下,州立法实施更为严格的消费者保护标准受到联邦优先权的重压,也从实质上削弱了对金融消费者的保护力度。中国应当借鉴美国信用消费制度,确立政府的监管目标和价值取向,以国家立法和地方立法相结合作为主要立法模式,完善信息披露制度并建立完备的信用评估体系,设立专门的信用消费者保护机构,以更好地维护消费者权益。     

Enhanced Special Drawing Rights: How China Could Contribute to a Reformed International Monetary Architecture

Since the end of the Bretton Woods era, the world has operated on a de facto system of free‐floating exchange rates, with the US dollar as the dominant international currency. The system, characterized by large pro‐cyclical capital flows and chronic imbalances, is inherently unstable, and has contributed to repeated crises, recessions and geopolitical tensions. One potentially “least‐difficult” line of reform would be to allow the evolution of a multi‐currency system, underpinned by an expanded role for Special Drawing Rights (SDRs). Attempts to promote wider use of the SDR have foundered on the liquidity premium. However, for Chinese corporations and institutions, at present restricted in their capital account activities, the SDR liquidity premium would appear less daunting. The Chinese authorities could provide policy encouragement for the use of SDRs by their institutions. This initiative, supported by China's Special Administrative Region Hong Kong, would kick‐start an international SDR ecosystem, and encourage even broader use of SDRs, to the benefit of international monetary stability.
