基于生态系统服务功能的森林社会效益价值评估——以云南省森林资源为例

森林除了具有经济价值和生态价值外,还具有基于生态系统服务功能所产生的社会效益价值。论文以云南省森林资源为例,采用房地产评估中常用的假设开发法为主要评估方法,结合森林资源所反映的社会效益价值增长特征,运用企业自由现金流量折现模型中的两阶段现金流折现模型,通过构建模型体系,分别从直接社会效益和间接社会效益两个维度对云南省森林资源的社会效益价值进行评估。其中,直接社会效益包括就业价值和景观游憩价值,间接社会效益包括科教价值、历史价值及文化价值,通过模糊综合评判计算各组成部分的不同影响权重得出直接和间接社会效益模型,以多元回归的方法构建森林生态总体社会效益价值模型并计算云南省森林社会效益价值。同时,将各部分价值结果分别与云南省第三产业GDP、人均GDP及云南省GDP进行对比分析,进而对云南省森林社会效益价值现有情况进行评价,并对今后的森林资源开发提出相关建议。     

Financial development,financial liberalization and social capital

The relationship between financial liberalization policies and financial development is controversial. The impact of these policies differs greatly across countries. In the literature, the quality of formal institutions has been identified as an important source of this heterogeneity, as countries with a weak institutional environment generally fail to benefit from financial liberalization. Using panel data covering 82 countries for the period 1973–2008, we find evidence that social capital may substitute for formal institutions as a prerequisite for effective financial liberalization policies. In particular, we find that during the post Washington-consensus period countries with a high prevailing level of social capital can ensure that financial liberalization positively influences financial development, despite the poor quality of their formal institutions.     

How to shake the invisible hand (when Robinson meets Friday)

We propose defining the invisible hand by: (i) modelling the mechanism itself (rather than just assuming its existence); and (ii) making explicit the limit conditions of its working. For that purpose, we simply assimilate the working of the invisible hand mechanism with the existence of a social preference such that individual and social optimalities are consistent. In introducing the possibility of interaction among individuals, we then suggest that the standard singleton case, or atomistic individualism, is just an extreme feature of a more general requirement that we call the  network agreement . Our main result is that the invisible hand mechanism does keep on working when there is an interaction between Robinson and Friday if the former (respectively, the latter) is sensitive to the latter (respectively, the former) in such a way that they exhibit some agreement in preferences. Hence, the singleton case naturally satisfies this property because neither Robinson nor Friday can disagree with himself. Further cooperative situations are also allowed in order to extent the invisible hand mechanism to cases with interactions.

Activation and variation of the United Nation’s cluster coordination model: a comparative analysis of the Haiti and Japan disasters

The coordinated response to extreme events is critical as illustrated by recent disasters in Haiti and Japan. As a way for coordinated provision of international humanitarian assistance to disaster-hit countries, the Office for the Coordination of Humanitarian Affairs (OCHA) developed cluster coordination model (CCM). With content analysis and network analysis of OCHA situation reports, this study checked four premises regarding activation of CCM, interaction between national and international actors, roles of proximity country, and level of cluster coordination. This study found that there were meaningful variations in implementing the CCM for 2010 Haiti and 2011 Japan disasters. From the analyses, we found that the current CCM may be vulnerable to black swan disasters; thus, extensive and active estimation of national disaster management capacities should be conducted to prevent collapse of national disaster management system. However, the reconciliation of state sovereignty and international humanitarian assistance also should be considered.     

基于因子分析法的我国各地区社会保障水平综合评价

社会保障水平直接关系着一个国家人民的生活质量和社会的稳定,社会保障水平的发展不能脱离经济发展和居民生活的需要。目前学术界很多对于社会保障的研究都是从理论角度考虑,但如果能够对社会保障水平进行定量研究,无疑可以从一个新的视角更客观、更科学的把握一个国家、地区的社会保障水平。本文选取了11个影响社会保障发展水平的指标,运用因子分析法建立综合评价模型,对社会保障发展水平进行定量分析和综合评价,我们了解到我国地区间的社会保障水平发展很不平衡。社会保障水平不仅与经济要素相关,同时也受人口结构、投资环境、产业结构等多种因素影响。政府应该积极调整人口结构和产业结构,完善投资环境,同时增加对社会保障的投入来缩小我国地区差异。

社保基金持股信息的市场反应——基于中国资本市场数据

在阐释社保基金及其投资情况和相关理论的基础上,采用超额收益法和多元回归分析法,分析我国资本市场对2009年四个季度和2010前两个季度公布的社保基金持股信息的反应。研究结果显示,资本市场对社保基金持股信息具有强烈的市场反应,被社保基金持股的上市公司股价超额收益非常明显。造成这种现象的原因除了社保基金管理者对股市精准把握外,我国资本市场的效率不足、信息不对称及社会保险基金会计信息披露的缺陷也是重要原因。因此,我国应加强公司治理,提高资本市场效率,规范社保基金会计信息披露。     

论公司的社会责任
