改善民生是中国城乡统筹改革实践的原动力

民生是中国城乡统筹改革实践的原动力。改革起始期,是民生呼唤下的自发改革与政策调整;改革深入期,是民生推动下的体制转轨与制度创新;改革攻坚期,是民生引导下的统筹发展与新农村建设。30年农村改革历程,致使民生问题的不断解决与改革的渐进式节奏相互吻合,推动着"人本"式的农村改革健康有序地发展。     

医疗卫生基本公共服务的城乡差距及均等化路径

当前,我国城乡之间的医疗卫生服务不均等已成为一个重要的社会问题。本文通过医疗卫生费用和医疗卫生资源的城乡数据分析得出城乡之间的医疗卫生公共服务差距巨大,并通过2000—2008年城乡医疗保健费用的泰尔指数分析,发现城乡组间对城乡医疗卫生公共服务差距的贡献基本上在80%以上,几乎是组内差距贡献的4倍,而从两组的内部差距来看,农村内部的不均等程度要稍高于城市内部的不均等程度,根据分析结果并从财政向农村医疗卫生的投入倾斜、城乡医疗保险制度的整合、医疗体制的深化改革等方面就如何促进医疗卫生公共服务城乡均等化进行探讨。     

Institutional environment and firms' sources of financial capital in Central and Eastern Europe

The external business environment is a major determinant of which sources firms select to obtain financial capital. We examine how the regulatory, political, and financial dimensions of the institutional environment influence the extent to which firms rely on informal sources of financial capital. The analyses of data from 2869 firms in twenty-six transition economies in Central and Eastern Europe (CEE) indicate that ineffective regulatory system, underdeveloped financial system, and government corruption are strong determinants of firms' reliance on informal channels for financial capital. We also find that smaller firms are more vulnerable when the local financial system is underdeveloped and the regulatory institutions are less effective in these transition economies. A subgroup analysis of firms' forms of establishment shows that private firms are sensitive to the level of development of the local financial system and state-owned enterprises are particularly sensitive to the degree of corruption.     

Organizational governance and TMT pay level adjustment

This paper analyzes how the characteristics of boards and structure of ownership moderate a firm's capacity to adjust top management team (TMT) pay levels in the face of changes in its economic and complexity conditions. Using panel data from Spanish listed companies between 2003 and 2007, the results indicate that, over time, characteristics of corporate governance system contribute to give a fundamental importance to boards and ownership structure in the determination and adjustment of TMT pay. These associations appear to be even stronger than those that in other Western European and North American countries. Both the Spanish cross-holding and concentrated firms' ownership structure, and socially intervened boards play a major role in the high levels of pay received by the TMT, which, in turn, reflect a moderate adjustment of compensation practices to variations of surrounded environment factors.     

农村公共产品供给的多元化体制构建

现行的农村公共产品供给制度安排的基本框架是“供给主导型”体制,在这种体制下,农村公共产品供给存在供给总量不足、供给结构失衡、供给绩效低下等问题。针对农村公共产品供给所存在种种问题,提出要构建“需求主导型”的多元化供给体制,而多元化供给体制的建立应是在相应机制的协调下多主体合作推动的结果。另外,又从机制设计的角度提出构建多元化供给体制的创新措施,并提出了相应的对策建议。

Dynamic land use and land cover changes and their effect on forest resources in a coastal village of Matemwe,Zanzibar, Tanzania

Recent land cover change estimates show overall decline of tropical forests at the regional and global scales caused by multiple social, cultural and economic factors. There is an overall concern on the prevailing land use practices, such as shifting cultivation and extraction of forest materials as agents of forests losses, but also new, emerging land uses are threatening tropical forests. Understanding of the long-term development and driving forces of forest changes are needed, especially at local levels where many decisions on forest policies and land uses are made. This paper addresses the importance of such information for improved estimates of forest dynamics by studying local level land cover and land use changes during the last 50–70 years in the Eastern African tropical island of Zanzibar, Tanzania. The paper discusses the role of traditional and new land uses mainly subsistence farming, tourism and government interference through tree planting, in the long-term development of the forests at the village level. The material for the study is gathered from the interpretation of archival maps and aerial photographs combined with contemporary digital aerial photographs. The analyses are based on the mapping, spatial sampling and spatio-temporal change trajectory analysis (LCTA) of forest land cover, forest land uses and settlement patterns with GIS and statistics. Six distinct forest land cover change trajectories were identified and these illustrate dynamic and heterogeneous nature of the forests. Closed forest cover has dominated throughout due to cyclical land use patterns, but over 70% of the land area has been continuously transforming between closed, semi-open and open land cover conditions. Land use turnover rates indicate that hardly any forest areas are left untouched from the forces, which remove and re-establish forest vegetation in the long run. Land cover and land use change trajectories are spatially fragmented in the studied landscape. Majority of forest loss-gain dynamics is caused by shifting cultivation, while forest losses are most dramatic along the coast, where traditional and new land uses meet and land uses pressures are highest. The study suggests that landscape change trajectory analyses, where contemporary and historical information on land uses and land cover changes are spatially linked, can provide valuable aspects into local level forest land use planning and management strategies. For the case study, the findings suggest the following key forest management strategies for consideration: (1) establishment of a protected forest/scrubland in participation with the local stakeholders, especially the farmers, (2) promotion of areas for permanent agricultural practices, while simultaneously introducing management controls in the traditional slash-and-burn farming areas, and (3) promoting new livelihood opportunities for the farmers, who have traditionally been dependent on forest resources, meanwhile introducing alternatives for fuel wood for cooking.

Which institutional investors matter for firm survival and performance?

Using data that spans three decades, we assess the diverse roles of institutional investors in impacting survival and performance of chronically underperforming firms and contrast the results for consistently overperforming firms. We find material differences in investor roles and investment returns between these samples. Differentiating among institutional types, controlling for prior performance and attrition bias provides insights unattainable by examining aggregated holdings. For underperformers, results are negative for activist pension funds and long-term institutions, positive for activist hedge funds and short-term institutions, and mixed for institutional blockholders.
