我国社会保障支出的地区差异分析

文章首先运用GE指数分解法,分析我国社会保障支出区域差异及贡献率;然后运用GINI系数分解法,分析社会保障各项支出对总体差异的贡献率。结果表明:三大区域总体、区域内及区域间的差异基本呈下降趋势,期间略有起伏,但区域内差异远远大于区域间差异;东部、中部和西部地区差异变动趋势不一致,且对总体差异的贡献率差别较大;社会保障各项支出的贡献率差异较大,其中社会保障补助支出成为总体差异的主体因素。文章最后对实际测算结果作进一步分析,并提出相应的政策建议。     

Obstacles to achieving cross-border tourism governance: A multi-scalar approach focusing on the German-Czech borderlands

This paper aims to identify distinctive obstacles to the establishment of tourism destination governance in both transnational and within-country borderlands. Analysis of the German-Czech borderlands, a region also incorporating within-country borders between three German federal states, indicates the multi-scalar and political contestations of cross-border tourism collaboration. Local tourism projects are generally successful, both on a transnational German-Czech level and between the German states of Bavaria, Saxony and Thuringia. However, structural cross-border destination management does not exist because of (transnational) multi-scalar institutional alignment problems and (internal) tourism-specific destination-level power contestations. Understanding destination management processes in borderlands, therefore, requires: (i) explicit multi-scalar analysis; (ii) recognition of both transnational and within-country contexts; (iii) more cross-pollination between tourism planning and cross-border governance research.

物流系统混沌边界确定及其模型效应分析

混沌理论作为解决经济系统中存在的大量非线性问题的一种全新研究方法,借助其非线性动力学模型对物流系统这一典型非线性复杂经济系统边界进行界定,有助于物流系统的正常运行.物流系统涉及交通运输、工业生产、商贸流通、邮政通信等各行各业,并受经济政策、产业环境及社会环境等诸方面因素的影响,必须按系统、分层次明确各级物流系统(企业物流系统、区域物流系统、物流供应链跨行业混序系统和社会物流大系统)的边界范围及其所包含的要素,并以此为基础分析物流系统的混沌特性和范围界定.文章通过测度系统的熵对系统是否产生混沌进行判定,能够对企业物流系统状态进行定量化描述,表征企业系统状态的复杂与有序程度,确定物流系统内部的不确定性,可以有效控制物流系统,实现物流系统经济效益的最大化.     

Exotic Passport Options

The Vanilla Passport Option is an insurance against trading loss. In this paper, we add various exotic features to the Vanilla contract and price the resulting financial products. The assumptions that we make are the same as the Black-Scholes ones and the resulting pricing equations are Hamilton-Jacobi-Bellman type equations or parabolic free boundary PDE's which can be solved via finite difference methods.     

王朝制度渐进视角下岭南土酋族属的建构--以钦州宁氏家族为中心

岭南钦州的宁氏兴起于南朝末,活跃于隋唐,与高州冯氏、冼氏并称,是岭南地区的少数民族首领,在隋唐文献中被称为越人。许多学者仅仅根据清代民国出土的两方隋唐宁氏家族墓志,就得出宁氏为“汉族移民后裔”的观点。而将有关宁氏家族的文献记载与出土墓志进行对照分析,可以发现岭南宁氏的真实身份为当地土著,宁氏将自身族属建构为“汉族移民后裔”,实际上反映了王朝制度在岭南民族地区的渗透与岭南边疆的内地化进程。     

民族地区公共服务能力解释结构模型研究

当前学界对政府公共服务能力的研究已逐步深入,但尚存不足。如重宏观轻微观,要素抽取随意性大以及对民族地区公共服务能力讨论过少。针对以上不足,文章运用系统分析方法ISM建立了“民族地区公共服务能力解释结构模型”．该模型可让管理者从投入到产出的动态过程中,掌握公共服务能力的形成和提高,了解各要素与系统功能的关系。     

套牢问题与企业边界的关系探讨

关于企业边界的研究,最有影响力的工作集中于套牢问题。目前为止,至少存在三种学派对此做出了研究:契约经济学流派、交易费用经济学流派、新产权经济学流派。本文旨在综述这三个主要学派的观点,并比较它们的研究切入点和彼此之间的不同点并进行评论。研究表明,三个学派基本认同套牢问题产生的根源为:人的有限理性、契约不完全以及资产专用性投资,但是在治理措施上分别产生了契约治理、长期动态(声誉考虑)治理、组织治理等。

Impact of an urban growth boundary across the entire house price spectrum: The two-stage quantile spatial regression approach

This study provides evidence for the impact of an urban growth boundary (UGB) on house prices. The study employs a two-stage quantile spatial regression method on a dataset that inventories sales transactions of single-family houses within two miles of either side of the eastern boundary of the primary UGB in King County, Washington. The results show that while the UGB decreases house prices across the entire house price spectrum, the impact is uneven; it is most pronounced for houses in the 5th to 8th decile of prices. These findings should encourage policy makers to adopt sub-housing-market-level policy approaches to address UGB and other urban and regional development policies’ potential impacts on house prices.
