“新金融”发展态势及上海的鼓励政策研究

中国式"新金融"规模不断扩大,对中国经济发展和宏观调控产生了重要影响。它在一定程度上使得经济增长与实体经济背离,也未能完全解决中小企业融资难问题。当前政策的出发点,不应仅出于控制金融风险而对"新金融"加以限制,更多的还是应考虑如何加大力度引导资金流向中小企业等实体经济。上海"新金融"政策定位,应借助"新金融"体系,引导社会资金流向实体经济,并以金融支持科技创新和产业升级转型为重点,以活跃和繁荣金融机构和中介服务体系为抓手,构建上海"新金融"鼓励政策。     

Efficiency and effectiveness of knowledge management systems in SMEs

This paper proposes a 3D fuzzy logic methodology to assess the efficiency and effectiveness of knowledge management systems (KMSs) adopted by small and medium enterprises (SMEs) and identifies a classification bringing together the behaviour of SMEs when adopting KMSs. The proposed methodology was previously tested on an individual SME and then implemented on a sample of SMEs. The results highlight that there is an ample variety of behaviours related to the nature of knowledge and the KMSs used. Specifically, four typologies of behaviour are identified: the efficient and effective SME, the effective but inefficient SME, the efficient but ineffective SME, and the inefficient and ineffective SME. The results show that only 18% of surveyed SMEs are efficient and effective for both KM-Tools and KM-Practices, the remaining 82% are inefficient or ineffective for KM-Tools and/or KM-Practices. Lastly, the paper shows how this methodology may be used by an SME as a managerial tool to suggest appropriate changes to improve the efficient and effective adoption of KMSs supporting SMEs in the knowledge management processes.     

A study of quadratic inference functions with alternative weighting matrices

Quadratic inference function (QIF) is an alternative methodology to the popular generalized estimating equations (GEE) approach, it does not involve direct estimation of the correlation parameter, and thus remains optimal even if the working correlation structure is misspecified. The idea is to represent the inverse of the working correlation matrix by a linear combination of some basis matrices. In this article, we present a modification of QIF with a robust variance estimator of the extended score function. Theoretical and numerical results show that the modified QIF attains better efficiency and achieves better small sample performance than the original QIF method.

A Bayesian approach to non-parametric monotone function estimation

Summary.  The paper proposes two Bayesian approaches to non-parametric monotone function estimation. The first approach uses a hierarchical Bayes framework and a characterization of smooth monotone functions given by Ramsay that allows unconstrained estimation. The second approach uses a Bayesian regression spline model of Smith and Kohn with a mixture distribution of constrained normal distributions as the prior for the regression coefficients to ensure the monotonicity of the resulting function estimate. The small sample properties of the two function estimators across a range of functions are provided via simulation and compared with existing methods. Asymptotic results are also given that show that Bayesian methods provide consistent function estimators for a large class of smooth functions. An example is provided involving economic demand functions that illustrates the application of the constrained regression spline estimator in the context of a multiple-regression model where two functions are constrained to be monotone.

Chronic Musculoskeletal Pain:

Two diseases, osteoporosis and osteoarthritis, are responsible for a majority of the chronic musculoskeletal pain that older women experience. Osteoporosis is the metabolic bone disease most common in older women and is responsible for fractures, kyphosis, and chronic pain. Osteoarthritis, the most commonly diagnosed musculoskeletal problem in older women, causes degeneration of the weight-bearing joints in the body, resulting in limited function and chronic pain. In this paper, these and other common disorders are briefly described and typical coping strategies used by older women in pain are reviewed. In addition, potential multidisciplinary treatment regimens are discussed.     

小城镇发展与财政建设非良性互动问题研究

小城镇发展与财政建设是一种动态的、相互作用、相互制约的循环关系。目前我国东西部不发达地区普遍存在着小城镇财权与事权不对称、财政性资金管理混乱、财政收支结构不合理、财政负债严重等影响小城镇发展的典型问题,从根本上抑制着小城镇财政建设和可持续发展之间的良性互动作用的充分发挥。文章从小城镇经济发展水平、财政管理体制和行政管理体制三方面深入分析原因,指出小城镇发展与财政建设非良性互动的症结之所在,提出促进小城镇发展与财政建设良性互动的改革方案。     

Small area estimation for longitudinal surveys

Over the last few years many studies have been carried out in Italy to identify reliable small area labour force indicators. Considering the rotated sample design of the Italian Labour Force Survey, the aim of this work is to derive a small area estimator which borrows strength from individual temporal correlation, as well as from related areas. Two small area estimators are derived as extensions of an estimation strategies proposed by Fuller (1990) for partial overlap samples. A simulation study is carried out to evaluate the gain in efficiency provided by our solutions. Results obtained for different levels of autocorrelation between repeated measurements on the same outcome and different population settings show that these estimators are always more reliable than the traditional composite one, and in some circumstances they are extremely advantageous.The present paper is financially supported by Murst-Cofin (2001) Lutilizzo di informazioni di tipo amministrativo nella stima per piccole aree e per sottoinsiemi della popolazione (National Coordinator Prof. Carlo Filippucci).
