安徽省城市用地扩展研究——以六安市为例

以六安市为例,利用相关城市统计资料、相关城市图件,对撤地设市十年来六安城区土地扩展情况进行研究,并分析其驱动力因素。得出撤地设市以来六安市城市扩展速度明显增加,尤其2008—2010年扩展量占十年来总扩展量的34．07％,且年均增加4．88kmu;城市扩展动态度和城市用地效率也呈现明显的上：升趋势。城市扩展及其方向受到了社会经济条件、人口、交通、政策等因素的影响。

The impact on stock prices of deferral and elimination of internal control audit requirement for small firms

This paper examines the cumulative market reaction to the events related to deferral of internal control audit requirement under the Sarbanes-Oxley Act of 2002 and its elimination under the Dodd-Frank Act of 2010 for nonaccelerated filers (small firms). We document that small firms experienced negative cumulative abnormal returns around these events; and the differences between the cumulative abnormal returns for small firms and the two control groups (accelerated and large accelerated filers) were negative and significant at the 1% level. These results support the notion that market participants value the reliability of financial information irrespective of the firm size. Within the small firms, we find no firm characteristic significantly explains the market reaction to the events considered. That is, all small firms lost market value in reaction to the events that delayed and eliminated their internal control audit requirement.     

Effect of credible quality investment with Bertrand and Cournot competition

We show how credible revelation and ability to commit to quality choice effect equilibrium qualities and welfare when product market is either Bertrand or Cournot competition. We show that results depend on the type of competition but not generally on the cost of quality function. We show that with Bertrand competition, the equilibrium qualities are lower with credible commitment. Competition is moderated and producer surplus is higher and consumer surplus lower. With Cournot competition, higher quality will be better but lower quality will be worse with credible commitment. Consumer surplus is always greater with credible commitment and if cost does not increase too quickly with quality, producer surplus will also increase. Thus credible commitment is a collusive device with Bertrand competition but it can improve social welfare with Cournot competition.

I am forever in debted to Mordecai and fellow students – Luis Cabral, Peter DeMarzo, John Hillas, Michihiro Kandori, Steve Langois, Patrick McAllister, Steve Sharpe, Peter Streufert, Steve Turnbull and Gyu-Ho Wang – for their criticism and encouragement. I also benefited from comments from Yi-Heng Chen, Jin-Li Hu, Kala Krishna, Jinji Naoto, Thomas J. Prusa, and Shyh-Fang Ueng at various later stages of this work. Last but not least, I am grateful for the detailed comments of the referee.     

A critical appraisal of the reporting quality of published randomized controlled trials in the fall injuries

To evaluate the quality of reporting in published randomized controlled trials (RTCs) in the field of fall injuries. The 188 RTCs published between 2001 and 2011, indexed in EMBASE and Medline databases were extracted through searching by appropriate keywords and EMTree classification terms. The evaluation trustworthiness was assured through parallel evaluations of two experts in epidemiology and biostatistics. About 40%–75% of papers had problems in reporting random allocation method, allocation concealment, random allocation implementation, blinding and similarity among groups, intention to treat and balancing benefits and harms. Moreover, at least 10% of papers inappropriately/not reported the design, protocol violations, sample size justification, subgroup/adjusted analyses, presenting flow diagram, drop outs, recruitment time, baseline data, suitable effect size on outcome, ancillary analyses, limitations and generalizability. Considering the shortcomings found and due to the importance of the RCTs for fall injury prevention programmes, their reporting quality should be improved.     

The Challenge of Humanistic Economics

The Center for Medicare and Medicaid Services (CMS) created the Hospital Compare Program in 2003 to increase transparency between healthcare providers and consumers. Implemented in 2005, this transparency consists of hospitals' collecting and making publicly available a set of hospital quality score measures. The CMS induced participation by financially penalizing hospitals that did not publicly report a specific subset of these measures (called “starter” measures). Three years into the program, the penalty for non-reporting both the starter measures and other (“non-starter”) measures was increased. I use a difference-in-differences methodology to analyze the effect of the increased CMS penalty on the likelihood that a hospital publicly reported its starter and non-starter measure scores. I find that the penalty had an economically and statistically insignificant effect on the probability that a hospital publicly reported its starter scores, but a statistically significant 8.0 percent effect (p-value<0.01) on whether it reported its non-starter scores. These findings are robust to a series of alternative empirical specifications.     

少数民族地区民俗旅游产品游客体验质量要素体系构建研究——以凤凰为例

关注游客对民俗旅游产品的体验需求,有利于做好游客的体验管理,提升游客的体验质量,实现少数民族地区民俗旅游产品的可持续发展。以体验经济为时代背景,从游客体验角度出发,在梳理旅游体验质量影响要素的基础上,提出少数民族地区民俗旅游产品游客体验质量要素体系的理论模型假设;通过随机抽样的调查方式,采用因子分析和方差分析方法,构建了少数民族地区民俗旅游产品游客体验质量要素体系,包括产品体验、环境体验、管理体验和个人能力4个主要素;并在此基础上,提出了凤凰民俗旅游产品游客体验管理对策,即打造核心体验产品、构筑完美体验环境、加强全面体验管理和高度挑战个人能力。     

The advanced experience of foreign countries on China＇s land leasing management

土地出让金在有效利用国土资源、调节收入分配、增加公共财政等方面发挥了积极的作用。但是,分税制改革后地方政府对土地买卖的过分依赖带来的野蛮拆迁、房价虚高等问题也随之成为阻碍城市化进程健康发展的重要因素。如何对土地出让金进行合理征收和科学管理成为当下执政者亟特解决的问题。     

合作社生猪质量供给困境与治理研究——基于集体行动理论的视角

专业合作社成员在空间分布上呈现出明显的地缘性特征,使得合作社对生猪质量控制具有天然的优势,但仍无法避免成员“搭便车”的困境。文章以奥尔森的集体行动理论为指导,设计了选择性激励、允许成员异质性以及强制措施等治理机制,并通过对金诚众和合作社的案例分析,提出扶持合作社进行生猪品牌建设,提高生猪抽检比例,加强猪肉产品的认证管理等政策建议。
