福建省电子类上市公司资本结构影响因素的实证研究

本文采用多元线性回归分析方法,对影响福建省电子类上市公司资本结构的因素进行了回归分析。分析结果表明:企业规模、资产管理能力与上市公司的资本结构呈正相关关系;公司盈利能力、短期偿债能力与资本结构呈负相关关系;成长性、实际税负与资本结构的相关性较小。     

规划理论和实践中的空间观念辨析

规划理论和实践中的空间观念塑造着我们周围的人造环境。空间观念的发展呈现出从绝对到相对、从时空分离转向时空关联、从一元到多元的变化趋势。20世纪以来规划理论逐渐吸纳相对空间观念,但迄今为止规划实践仍以绝对空间观念为主导。绝对空间观念成为规划实践低效性的深层原因,但是完全放弃绝对空间观念而将相对空间观念引入规划理论和实践不仅存在很多困难,而且会造成认识和实践上的混乱,科学的空间观念应该将绝对和相对结合起来形成多元空间观。我国规划理论研究和实践仍以绝对空间观念为主导,了解绝对空间观念的不足和吸纳相对空间观念的合理性具有重要的理论和实践意义。

Prediction of the next hypercalcemia free period: application of random effect models with selection on first event

The length of repeated hypercalcemia free periods of patients with bone metastasis of breast cancer with at least one hypercalcemic event was modelled according to a generalized linear mixed model formulated in terms of transition probabilities and according to a latent variable model. In the former case the periods were assumed to be lognormally distributed with two variance components (patients and residue). In the latter case the conditional intensity given a patient was assumed to be the intensity of the Weibull distribution, while the random patient effect (frailty) was assumed to be drawn from a gamma distribution. In both cases the selection of only patients with at least one hypercalcemic event was taken into consideration. In both models the variance of the patient effect turned out to be negligible. For the second and later periods the Weibull appeared to fit better than the lognormal model. For the first period there was almost no information available.     

The Impact of Agricultural Import Tariff on Economic Growth： Evidence From Mercosur Countries

This research paper attempts to determine the relationship between agricultural import tariff and economic growth of Mercosur countries over the period 1996-2007 using regression analysis as well as evaluates the gains and losses from the group＇s trade policy over the same period. The introductory part of this paper focuses on the dynamics of changes in economic growth, trade, and import tariff of these countries over the last two decades. The results of the performed regression analysis of panel data suggest that trade liberalization has a quantitatively significant positive effect on growth. By using the coefficient estimates on tariff, the authors perform a quantitative evaluation of gains and losses from trade policy, for which tariff measures to trade （imports） are used as a proxy.     

要素市场配置与我国城乡居民收入差距研究

在我国城乡要素市场人为分割情况下,劳动力、土地、资本等要素在城乡间的流动受到限制,要素的这种错误配置导致了较低的配置效率,从而使得城乡间经济收敛的内在机制无法发挥作用。通过选取一定的统计指标,对1990-2011年我国城乡要素收入进行分解,用定性与定量相结合的方法分析要素市场配置对城乡居民收入差距的影响。研究表明,土地要素和劳动力要素对城乡居民收入差距影响最大。应采取完善要素市场配置体制,促进劳动力、土地、资本等要素合理配置,完善政府宏观调控职能等政策缩小城乡居民收入差距。     

An Epistemological Reflection on Social and Solidarity Economy

Social and Solidarity Economy (SSE) is emerging as life affirming solutions to the global crises through the multiple ways people locally reinvent economic life on the margins of the capitalist system based on values of solidarity, reciprocity and sustainability. Although the SSE builds on a strong foundation of real practices and institutions of economic transformation as the way forward for us, this paper argues that this world of practice is in need of its theory to frame discourses and engage with the bigger picture with confidence as an alternative to the dominant economic paradigm. The author argues that the orthodox economics, with its ontological construct of the homo economicus, Cartesian dichotomy and logical positivist epistemology severely constrains our abilities to understand and appreciate economic alternatives based on ‘other’ rationalities. Hence, there is a need for an epistemological revolution to construct a coherent theoretical framework from the wreckages of the neoclassical economics for the SSE. This paper seeks to outline the basic structure and the key elements of the ontological and the epistemological framework for this ‘science-in-the-making’ as a step to stimulate further debate for a paradigm revolution.     

老年人养老方式选择的影响因素研究——基于CHARLS数据的实证分析

本研究在CHARLS调查所获得的微观数据的基础上进行,首先对老年人养老方式选择的结果和老年人人口特质、健康状况、经济状况等方面的6个变量进行关联分析,再通过二项Logistic回归模型,将是否选择机构养老作为被解释变量进行回归分析。结果表明非机构养老方式仍是老年人的主要选择,年龄、婚姻状况、慢性疾病情况、经济状况等因素与老年人养老方式的选择存在显著的关联并对选择结果产生影响。     

How Do Household Tasks Shape Employment Contracts? The Provision of Care in Portugal

This study illustrates the complexities involved in outsourcing domestic work to the market. It draws on an original dataset of paid domestic workers in Portugal to examine how specific tasks interact with and explain contractual arrangements. A fuzzy cluster analysis categorizes paid domestic workers into caregivers and cleaners; however, a great degree of overlap implies that caring also entails cleaning tasks necessary for the care receiver’s well-being. A subsequent Tobit regression analysis shows that caregivers have more formal and stable contracts but earn lower wages and have longer working hours relative to cleaners. The study finds a segmentation of national origin and that some migrants are at a disadvantage in care work. The study also examines how employers deal with the idiosyncrasies of domestic work such as navigating trust-related issues.     

中国商业银行竞争力及影响因素分析:2002—2009年

本文选取中国14家上市商业银行作为研究对象,利用2002—2009年的数据,通过定义社会生产效率、服务效率、盈利效率和成长效率,研究中国银行业的整体效率、效率值动态变化和各银行的效率情况。结果表明,四大国有控股商业银行与一般股份制银行和城市商业银行相比,其社会生产效率、盈利效率过低,但如果将投入变量中的员工数目换为工资薪酬,国有控股商业银行的效率则有很大提升;股权结构会影响效率值,但国有股与效率值不一定负相关,而外资股和效率值正相关,只对于生产效率成立,对于服务效率和盈利效率刚好相反。
