股权分置改革对我国上市公司绩效的影响

文章以沪深2005年年底完成股改的239家上市公司为研究样本,通过描述性统计和回归分析,对股权分置改革的实施对我国上市公司绩效的影响进行了实证研究.研究结果显示:第一大股东持股比例下降幅度与公司绩效显著负相关.这说明了股权分置改革对我国上市公司的绩效产生了一定的影响,同时也说明了上市公司的国有股减持应按步骤循序渐进地进行,不能减持幅度一次过大.     

RATES OF RETURN TO EDUCATION IN BOTSWANA: RESULTS FROM THE 2002/2003 HOUSEHOLD INCOME AND EXPENDITURE SURVEY DATA SET

Using the most recent Household Income and Expenditure Survey data (2002/2003), this paper presents current rates of return to education for Botswana. The results show that the rates of return have in general declined by one percentage point on average between the periods as shown in Table 2 . If we, however, look at the averages for the different school cycles, the fall in the average rates is quite significant at about six percentage points between the periods. The biggest fall is for secondary education, especially upper secondary education, which fell by 28 percentage points between the periods. The rates of return to tertiary education, however, rose by more than 50 percentage points. Ignoring upper secondary, the pattern of rates of return has remained similar to the results of the study based on the 1993/1994 data. Rates are higher for tertiary education and lower for secondary than for primary education. This results are still consistent with rates of return generally rising with level of education. At policy level, the results continue to support sharing of costs between Government and beneficiaries or their parents especially at tertiary education level. Second, the results indicate the need for the country to continue to vigorously pursue job creation and reorient the education system from emphasis on white collar jobs.

财政教育支出的农村减贫效应研究——基于网络空间结构的分析

运用修正的引力模型测算出我国财政教育支出的空间关联关系,以及财政教育支出对农村减贫的空间关联影响效应。实证结果表明：我国财政教育支出在空间关联上呈现出复杂、多线程的网络结构;区域间财政教育支出差异和人力资本差异与农村贫困联动矩阵呈现显著负相关,区域间技术发展水平差异和经济发展水平差异与农村贫困联动矩阵呈现显著正相关。加强我国农村贫困的治理,需要考虑财政教育支出的空间关联作用,实施定向的、梯度推进的区域协同策略。

Developing energy conservation and carbon reduction indicators for the hotel industry in Taiwan

This study develops and weights energy conservation and carbon reduction (ECCR) indicators for the hotel industry in Taiwan to create an instrument to help address climate change. Eighteen semi-structured interviews were conducted with senior hotel managers, environmental specialists, and government officials to identify the preliminary ECCR framework. An expert panel then was invited to review the structure of ECCR criteria and the compiled criteria in a structure for item modification. An analytic network process questionnaire survey was employed to determine the relative weights of the criteria. The data analysis reveals seven categories in the ECCR framework: communication and participation, top management commitment, energy, water, waste, building, and purchasing. A total of 32 indicators were identified and prioritized in terms of their relative importance to ECCR contributions. The results of this study suggest that the success of ECCR implementation depends primarily on management support and staff engagement. Hotel operators can improve their environmental management by initiating ECCR practices based on the proposed ECCR indicators.     

Traditional Management Systems, Poverty and Change in the Arid Zone Fisheries of Northern Nigeria

This paper, based on fieldwork results, explores traditional management systems (TMS) in the arid zone fisheries of north-eastern Nigeria with particular reference to their impact on rural poverty. The first section provides a historical background by tracing the evolution of the TMS since the nineteenth century, with reference to government policy on fisheries management and poverty alleviation. The second gives an overview of TMS, including definitions, distribution, principal objectives, regulatory mechanisms and the impact of TMS on the performance of the fisheries and on the livelihoods of rural people. The third considers the perceptions and attitudes of the fishing communities with regards to the fisheries and TMS. The paper concludes, paradoxically, that while TMS provide a basis for the sustainable livelihoods of many fishing people, they also reflect and enforce the social positions of the rich and powerful members of society who oversee them, at the expense of the poor. In the future, poverty alleviation in fisheries will need to incorporate both sectoral and non-sectoral strategies – dealing with the existing 'paradox of TMS' by encouraging appropriate institutional changes and community development, and recognizing the importance of employment creation in other sectors of the economy as a source of alternative income.     

‘I Don't Like My Children to Grow up in this Bad Area’: Parental Anxieties about Living in Informal Settlements

A growing body of research on informal settlements considers the experiences of children, but seldom outlines the daily parenting experiences of adult men and women. At the same time, policy on housing in South Africa points to the ways in which the ‘eradication’ of informal housing will help provide children with better futures. This article explores the social relation of parenting within an informal settlement in Durban, South Africa, bearing in mind the broader difficulties of parenting in poverty, and points to ways in which the material qualities of informal settlements contribute to feelings of anxiety in parents. It questions how these experiences might differ from or be similar to those of parents who live in generic contexts of poverty (but not necessarily informality). It concludes ultimately that living in an informal settlement does actually contribute to particular parental anxieties, but that there is no guarantee that informal housing eradication will remove these concerns.

欧美城市贫困集中研究述评及对我国的启示

从城市地理学、城市规划学和城市社会学的视角,综合评述了欧美国家城市贫困集中的现象,分析了贫困集中所造成的居民收入和就业机会下降、社会隔离及歧视加剧、社会治安环境恶劣、孩子遭受不良影响和公共配套设施短缺等问题,探究了市场、政府、特殊人文因素和产业结构转型等因素对贫困集中的影响。欧美城市经验为我国城市发展提供了有价值的启示,为了减少贫困集中以及由此引发的社会问题,政府应主动进行调控,缩小居民过大的收入差距,避免经济适用房和廉租房住区的集中布局,建设多样化混合社区,以及使公共住房政策由供给导向向需求导向转变。
