京津冀区域空间格局及其优化整合分析

本文以京津冀区域空间结构为研究对象,从点、线、网络和域面四个基本空间要素入手,研究提升区域竞争力的空间整合规律.研究认为,京津冀区域人口和城镇体系的空间分布不均衡,一方面,以自然条件为基础,呈现东南集中特征,另一方面,中小城镇分布以京广、京九、京哈铁路等为依托,呈现以北京为中心的强向心分布;城镇带分布大体可划分为京广线...     

旅游类专业应用型人才培养体系优化路径研究——基于产教融合背景

为了适应经济结构的调整和产业转型的升级,我国多次出台了关于“产教融合”的政策文件。如何借助“产教融合”实现旅游类专业应用型人才的培养目标,是地方本科高校旅游类专业教师需要探讨和实践的重要课题。本文以晋中学院旅游管理系为例,探讨产教融合背景下旅游类专业应用型人才培养体系的优化路径,并试图结合实践构建“围绕一条主线,依托三方协同,开展四类合作,实现六个结合”的1346人才培养体系,以期为有效提升旅游类专业应用型人才培养水平提供借鉴。     

Heckscher–Ohlin and agglomeration

We argue that embedding endowment-based comparative advantage within a standard NEG framework helps solve the indeterminacy due to multiple equilibria and the ambiguity concerning the relation between integration and specialisation (monotonicity versus non-monotonicity) typical of the NEG literature. In particular, we show that if endowments are in the FPE set, the process of trade integration involves an overshooting of international specialisation and relative factor prices with respect to the free trade level determined by factor abundance. In contrast, if endowments are outside the FPE set, then, even in the presence of agglomeration forces, specialisation and factor prices are monotonically related to trade costs, as implied by the standard trade theory. We argue that the model can shed light on some puzzling stylised facts.     

东盟与东亚经济合作

20世纪90年代以来，东亚出现新地区主义发展趋势，其基本思想是在加强南北合作的基础上，在本地区建立一个开放的、多层次、有大国参与的多边自由贸易区，同时加强双边合作。在此背景下，东盟不断调整其区域经济一体化战略，重视开放的、发展的地区主义，并在推动东亚区域合作进程中发挥了重要作用。     

论转型时期的社会分化与整合

我国当前正处于急速的社会转型时期,社会结构的快速分化对原有的整合方式提出了挑战,以至于在社会分化和整合之间出现了断裂,对我国的社会稳定产生了不可忽视的影响.在新形势下,我们必须建立一种新的社会整合方式以适应社会的急速分化,维护社会的稳定.     

Flexible Integration? Mandatory and Minimum Participation Rules

For a club such as the European Union, an important question is whether a subset of the members should be allowed to form “inner clubs” and enhance cooperation. Flexible cooperation allows members to participate if and only if they benefit, but it leads to free‐riding when externalities are positive. I show that flexible cooperation is better if the heterogeneity is large and the externality small, but that rigid cooperation is the political equilibrium too often. Both regimes, however, are extreme variants of a more general system combining mandatory and minimum participation rules. For each rule, I characterize the optimum and the equilibrium.     

多哈回合谈判全面中止的政治经济学分析

2006年7月持续近5年之久的世贸组织多哈回合全球贸易谈判全面中止。多哈回合谈判全面中止产生的最重要影响是打击了人们对多边贸易体系的信心，从而可能引发新一轮的区域和双边贸易自由化谈判并由此加剧贸易保护主义。从历史经验来看，多哈回合谈判中止可能仅是暂时性的，经过发达成员和发展中成员的积极努力，最终会重启并完成新一轮全球贸易谈判。     

Exchange rate volatility and regime change: A Visegrad comparison

We analyze exchange rate volatility in the Visegrad Four countries during the period in which they abandoned tight regimes for more flexible ones. We account for path dependency, asymmetric shocks, and movements in interest rates. In addition, we allow for a generalized error distribution. The overall findings are that path-dependent volatility has a limited effect on exchange rate developments and that the introduction of floating regimes tends to increase exchange rate volatility. During the period of flexible regimes, volatility was mainly driven by surprises. Asymmetric effects of news tend to decrease volatility under the floating regime. Interest differentials impact exchange rate volatility contemporaneously under either regime, although we find no intertemporal effect of interest differentials.
