内蒙古财政支出结构的分析及其对经济增长影响的研究

对财政支出结构的研究是当前我国的一个热门课题,它既可以帮助财政支出目标的实现,又可以考察财政支出结构是否促进经济增长。文章首先对财政支出的相关指标测算内蒙古财政支出的规模,其次根据财政支出职能划分内蒙古财政支出结构进行分析,然后应用回归模型分析内蒙古财政支出结构对经济增长的影响,最后根据以上分析的结论,提出优化内蒙古财政支出结构的相关建议。     

Multi-stakeholders’ assessment of bike sharing service quality based on DEMATEL–VIKOR method

ABSTRACT

Bike sharing is a sustainable mode of urban transportation. Assessing the perceived service quality is essential to improve the development of bike sharing. Most of the existing research evaluates the service quality of bike sharing only from the perspective of its users. This study assesses the perceived quality gap among four different stakeholders including government regulators, platform operators, bike association and users. First, an evaluation criteria system consisting of sixteen criteria obtained from the five dimensions of tangibles, reliability, responsiveness, assurance and empathy is constructed based on a revised service performance model. Thereafter, a hybrid multi-criteria decision-making model that combines Decision-Making Trial and Evaluation Laboratory (DEMATEL) with VIsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is proposed. Then, the model is applied to evaluate the service quality of bike sharing in Xi’an City. Finally, some useful suggestions are given to improve the bike sharing service quality from the perspective of multi-stakeholders.     

我国地方政府债务风险及其预警:问题及对策

我国地方政府财政风险有其特殊的历史背景和生成机理,而且有关预警信息取得困难,财政危机的表现模糊,这些问题给有效预警带来困难。不仅如此,现有的预警研究在预警理论和预警方法上也存在诸多问题,本文试图根据我国地方政府财政风险的特殊性以及现有预警存在的问题,提出相应的预警对策。

住房抵押贷款支持证券的利率风险度量——基于"建元2005-1 MBS"A证券的实证

住房抵押贷款支持证券中隐含期权的存在导致未来现金流不确定,久期和凸度等利率风险管理工具不再适用。本文基于OAS理念建立了住房抵押贷款支持证券的利率风险度量过程:采用多项式样条函数法构建零息票收益率曲线,采用Vasicek模型描述动态利率期限结构,通过蒙特卡罗方法模拟利率路径并确定未来现金流,采用ARMA模型描述和预测提前偿付率,进而计算出OAS、有效久期和有效凸度的值。最后以建元2005-1MBSA证券为对象进行了实证研究。     

中国农村贫困地区可持续发展分析

贫困是经济、社会、生态均有待提高的综合体,如果只注重单一方面的脱贫,忽视其它两个方面,扶贫的效益仍然是不经济的,还会损害子孙后代的福利,是不可持续的,极易返贫,反贫困必须从经济、社会、生态三方面进行综合治理,才能脱贫致富,走上可持续发展的道路。     

Adoption of professional management in Chinese family business: A multilevel analysis of impetuses and impediments

Building upon the market, institutional, and cultural perspectives, this paper identifies the major impetuses and impediments that affect the professionalization of Chinese family business at the environment, firm, and owner levels. Our integrative framework projects that whether a family business owner will adopt professional managers is largely determined by the relative strength of impetus factors and impediment factors. We then discuss the possible governance choices under different configuration of impetuses and impediments. This theoretical framework is expected to help set the momentum for further conceptual exploration and empirical study in this area.

ON THE PROFITABILITY OF RESALE PRICE MAINTENANCE WHEN DEMAND IS UNCERTAIN

A previous study finds that in a market where a manufacturer faces uncertain demand and sells to consumers through competitive retailers, the manufacture wishes to support adequate retail inventories by imposing resale price maintenance (RPM). I show that if retail inventories are allocated to consumers through first‐come‐first‐served rule rather than efficient rationing rule in the game with unconstrained retail competition, imposing RPM may not be profitable. It may not encourage more retail inventories either. RPM may also lower consumer surpluses and social welfare. This study casts some doubt on the demand uncertainty theory that supports RPM.
