自然保护地自然资源资产产权制度现状辨析

“建立以国家公园为主体的自然保护地体系”是党的十九大所提出的国家公园体制建设的新方向。实现自然保护地的有效保护管理是其重要内容，关键在于通过改革形成科学、合理的自然资源资产产权制度，而厘清自然资源资产产权制度的现状则是进行改革的前提。首先，对现行法律进行系统梳理，明确法律所认定的自然保护地中的自然资源类型。其次，从自然资源的产权种类及所有权改变、用益物权流转三方面总结了自然保护地自然资源资产的产权制度现状。再者，从各类自然保护地申报设立的条件和环保督查中反映出来的问题两方面入手分析了自然保护地的自然资源保护管理现状，从国家公园体制试点采取的措施出发分析了目前的改革探索，并提炼出自然保护地自然资源资产产权制度存在的四大问题，即自然资源资产产权的界定和要求较局限、自然资源所有权行使人虚位、公权与私权的利益协调机制不健全、改革探索中物权途径面临制度障碍。最后，从自然资源资产产权制度设计的角度提出了改革的4个方向。     

Divestitures,privatization and corporate performance in emerging markets

We use new firm‐level data to examine the effects of firm divestitures and privatization on corporate performance in a rapidly emerging market economy. Unlike the existing literature, we control for accompanying ownership changes and the fact that divestitures and ownership are potentially endogenous variables. We find that divestitures increase the firm's profitability but do not alter its scale of operations, while the effect of privatization depends on the resulting ownership structure – sometimes improving performance and sometimes bringing about decline. The effects of privatization are thus more nuanced than suggested in earlier studies. Methodologically, our study provides evidence that it is important to control for changes in ownership when analyzing divestitures and to control for endogeneity, selection and data attrition when analyzing the effects of divestitures and privatization.     

Private Wealth in a Developing Country:Evidence from South Africa

The point of departure of Piketty's influential Capital in the Twenty‐First Century (2014) was the dramatic growth of private wealth‐income ratios in advanced economies between 1970 and 2010. Using official balance sheet data for South Africa—the first country to publish such data in the developing world—, this paper examines to what extent this re‐emergence of private wealth was also experienced in the developing‐country context. First, we find that the South African current wealth‐income ratio is very close to its 1975 level, and much lower than those of Piketty's sample of advanced economies. Second, we show that the discrepancy is explained not only by South Africa's relatively low savings rates, but also by the reduction of wealth before and during the transition to democracy in the 1990s. Since then, private wealth recovered significantly, but the U‐shaped relationship does not support the argument that there is a clear correlation between the capital‐income ratio and capital share.     

信贷政策、银企关联与企业资本结构

本文从供给政策和银企关联两个层面出发,揭示信贷政策、银企关联对资本结构影响的理论机制,并提出3个理论假设,并以2003-2012年间360家上市公司为样本分别进行实证检验。结果表明,信贷供给和银企关联对资本结构具有显著的正向影响效应,并且两者之间存在显著的替代关系。鉴于此,必须加快发展和完善多层次资本市场,拓宽企业融资渠道,降低企业的融资成本;重视银企关联这一非正式制度安排对企业资本结构的作用,预防甚至减少违规现象的出现。     

Pro-cyclical effect of sovereign rating changes on stock returns: a fact or factoid?

This article examines the effect of changes in sovereign credit ratings and their outlook on the stock market returns of European countries at different phases of business cycle. Using standard four-factor model, it records a significant average marginal effect of credit rating announcements on stock market returns. Both magnitude and significance of the effect vary with business cycle and across announcement types. However, we do not find evidence of pro-cyclical effect of sovereign rating and outlook changes on stock returns. Our results show that stock markets react more negatively to rating downgrades in recovery phases and more positively to rating upgrades in contractionary period. Both results are statistically significant and robust to various sensitivity tests.     

中国家庭债务和资产积累关系的实证分析:1997-2008

笔者运用1997年～2008年中国家庭债务和家庭资产积累的时间序列数据,定量分析了家庭负债和家庭资产积累的关系。研究发现,家庭债务和家庭资产积累存在同向的长期均衡关系,家庭债务的变动会影响家庭资产的积累。笔者提出促进家庭资产合理配置和防范中国家庭债务快速增长带来的消极后果的相关建议,旨在为决策部门制定合理的经济政策提供参考。     

基于效用成本风险异质性的消费资本资产定价模型

资产定价既是现代金融的核心,也是许多困惑之所在,其中最著名的就是股权溢价之谜和无风险利率之谜。本文对消费资本资产定价模型中的效用成本做了重新思考,引入"效用成本风险异质性"的概念,并将效用成本区分为"消费效用成本"和"风险效用成本"。在此基础上,本文提出了消费资本资产定价模型的新形式,并对股权溢价之谜和无风险利率之谜进行解释。     

后金融危机时期中国货币政策选择——基于美国QE2经济后果的分析

二次量化宽松政策(简称QE2)是美联储在国内经济提振乏力、失业率居高不下以及世界经济复苏不平衡的背景下启动的。QE2或许能够使美国走出通缩的泥潭,也有可能催生资产泡沫,酝酿新的金融危机,但却无疑给世界经济,尤其是新兴市场国家的经济继续复苏蒙上了一层阴影,全球热钱将更加泛滥,世界经济秩序将遭到破坏,各国外汇储备将进一步缩水等。对此,我国中央银行货币政策必须加强与财政政策的配合,适时调整外汇储备资产结构,扩大本币结算合作,积极应对QE2的挑战。     

收益现值法在旅游资产评估中的应用研究

在经济全球化的条件下,资本的流动性越来越强,资本的逐利本能促使投资人常常进行跨国、跨地区的投资,投资的方式也越来越多样化。在旅游资源得到开发或初步有效开发的地区,直接投资新建项目的机会已经不多。收购、转让、控股和租赁是常见的投资方式。运用收益现值法对3个案例中的旅游资产的现值进行评估分析,较客观地反映了这些特定资产或某一类资产的本金化的价格。     

农村义务教育闲置资产产权界定问题探讨——基于陕西省的调查统计

明确界定农村义务教育闲置资产产权是实现闲置教育资源再利用的起点。由于农村义务教育投资结构复杂,现行法律法规和政策规定空泛、相互冲突,导致闲置资产产权界定困难。应借鉴国有企业产权界定模式,按照依法界定、分类确权的原则,构建所有权与使用权、处分权分离的农村义务教育闲置资产产权界定体系。
