我国西部大开发战略实施效果的阶段性评价与改进对策

利用统计数据,选取宏观经济水平、工业化发展进程、居民生活质量和生态发展状况等四大类指标对中国西部大开发战略实施10周年的政策效果展开系统评价。研究发现,尽管西部大开发战略促进了西部地区社会经济发展指标的全面好转,但东西部之间区域经济发展不均衡的系统格局并未改观,反而呈现进一步恶化趋势。因此提出了未来10年西部大开发战略向纵深推进的具体对策,比如增强东西部地区间产业联结与优势互补、强化西部各省域间经济发展的联动效应、西部投资应注重"点面结合、以点带面"等。     

公司增发与市值管理——基于中国A股上市公司的实证研究

采用2005—2014年中国A股有增发股份记录的上市公司的市场数据,检验了被广泛讨论的市值管理现象。结果表明:所有权性质、增发目的、增发对象、经营状况以及市值存在差异的上市公司,在其增发股份前后及期间的超额收益率和股价信息含量存在很大差异,这些差异与不同公司进行增发的诉求一致。这说明,中国A股市场广泛存在服务于公司控制人的市值管理行为。由于这些市值管理行为可能包括控制股价和侵害其他投资人,因此监管层应制定更为严格的法规来规范市值管理行为。     

Measurement of Economic Result in Public Organizations： A Departmental Analysis

The aim of this work is to demonstrate how public university hospital （UH） managers can improve the process of decision-making by using the measurement of economic value added to the society （EVAS） generated by these organizations. Thus, the economic values of the organization and its departments were calculated, according to the theory studied： measurement model of economic result of Slomski （1996）. It was considered the conduction of a case study in a public UH, evaluating its economic performance in a 3-year period. For the interpretation of results, the Data Envelopment Analysis （DEA） which categorized the departments of the hospital studied as efficient or inefficient was used. This study revealed that managers can improve the decision-making process by using the EVAS, since it has been established that this measurement of economic value has sensitivity to identify which of the economic value drivers should be emphasized in the management.

Import elasticities and the external constraint in Mexico

The paper estimates and analyzes an equation for intermediate imports in Mexico during the 1988–2006 post-liberalization period. While some results are obtained from Johansen's VECM model, most of the analysis is carried out within an Error-Correction ARDL framework, following the bounds testing approach of Pesaran et al. (2001). Besides showing that an aggregate equation for intermediate imports can be satisfactorily estimated, the paper focuses on two specific results. First, exports have a very significant effect on imports, and failure to control for this effect (as in most previous studies) can yield misleading results, like an over-estimation of the output elasticity of imports. Second, the response of imports to variations in the real exchange rate has fallen over time, presumably because of the rising share of maquila in Mexico's export basket and the increasing “vertical specialization” of non-maquila export production. Some implications of the estimation results are briefly discussed, making reference to the possible external constraint on Mexico's economic growth.     

Detecting big structural breaks in large factor models

Time invariance of factor loadings is a standard assumption in the analysis of large factor models. Yet, this assumption may be restrictive unless parameter shifts are mild (i.e., local to zero). In this paper we develop a new testing procedure to detect big breaks in these loadings at either known or unknown dates. It relies upon testing for parameter breaks in a regression of one of the factors estimated by Principal Components analysis on the remaining estimated factors, where the number of factors is chosen according to Bai and Ng’s (2002) information criteria. The test fares well in terms of power relative to other recently proposed tests on this issue, and can be easily implemented to avoid forecasting failures in standard factor-augmented (FAR, FAVAR) models where the number of factors is a priori imposed on the basis of theoretical considerations.     

Discapacidad y absentismo. Análisis empírico sobre seis países europeos

A partir de datos del Panel de Hogares de la Unión Europea (PHOGUE) sobre Austria, España, Grecia, Irlanda, Italia y Portugal de 1995–2001 se examina la influencia de la discapacidad en el absentismo laboral utilizando tres variables: el estado de salud autoevaluado, el número de visitas al médico y el número de noches de ingreso en hospital. Según los resultados, el absentismo entre los trabajadores con discapacidad es mayor. La gravedad de la discapacidad también tiene influencia. El efecto total de la discapacidad en el absentismo representa un incremento marginal de entre 6 y 26 días de ausencia al año (dependiendo del país).

黑山铜镍硫化物矿床成因与预测

长久以来甘肃北山地区一直就是基础地质和矿床地质理论研究以及找矿勘查热点,本区横跨3个不同的大地构造单元,区内前寒武纪和古生代地层出露广泛,构造形迹复杂,岩浆岩发育,金属矿床星罗棋布。文章从区域地质、矿床地质、矿床成因等因素,对甘肃肃北黑山铜镍硫化物矿床进行分析,根据本区的实际情况,对黑山矿床含矿超基性岩体的形成与空间展布规律进行新的研究判断,为未来找矿工作的思路和方向提出有益的见解及观点。     

普通高校收费定价模型研究

高等教育收费问题已经成为社会关注的热点问题。本文综合考虑了政府、家庭、学校及社会对高等教育成本的分担能力,制定了一个合理的承担比率,并以此为基础建立了学费定价模型,最后利用相关数据对模型进行了实证分析。
