去库存及建筑总量控制政策对三四线城市能源消耗的影响效应研究

近十年来房地产开发迅猛,在满足人们居住需求的同时也伴随着大量泡沫的涌现。中央提出的供给侧改革、去库存和能效提升给建筑部门指明了发展方向,有效地实施供给侧改革是建筑部门一项重要工作。拟通过开展去库存及建筑总量控制对三四线城市能源消耗的影响研究,为建筑部门的供给侧改革提供建议和参考。站在建筑部门宏观视角,通过文献调查,分析总结了建筑终端能耗影响因素及其影响效应,梳理了中国建筑总量、库存量及建筑领域能源消耗量总体情况,论述了三四线城市去库存、进行建筑总量控制的重要性;在此基础上,根据分析结果、三四线城市特点及数据可获得性,选定自变量和因变量及量化指标,运用岭回归方法,以6个城市的数据为例进行三四线城市建筑总量控制、去库存政策对城市能耗影响效果的定量分析;最后基于彼此间关系及研究过程中发现的问题对建筑部门的供给侧改革工作提出建议。

Does local political support influence financial markets? A study on the impact of job approval ratings of political representatives on local stock returns

Using data on job approval ratings of governors, U.S. senators, and the president, we find that firms located in states with high approval ratings outperform firms located in states with low approval ratings by .64% per month. Furthermore, this relationship is stronger when investors are actively involved in politics, when local politicians are closer to the center of political power, for small firms that have a larger proportion of local investors, and for financially strong areas where investors are ready to execute investments in local stocks. Overall, our study shows that investors’ political sentiment is important in determining stock returns.     

Solvency Ⅱ与C-ROSS非寿险保险风险最低资本要求比较研究——基于中国60家财产保险公司的经验证据

本文以非寿险业务保险风险最低资本要求为考察对象,研究了欧盟Solvency Ⅱ与中国C-ROSS的差异,并利用中国保险市场60家财险公司的经验数据,对两者之间的差异进行了实证和模拟分析。研究结果表明,Solvency Ⅱ和C-ROSS对中国财险公司保险风险最低资本要求存在差异。对于拥有传统业务结构的财险公司,Solvency Ⅱ对保险风险最低资本要求更高,但是这种差距随着公司业务规模的缩小而减弱;对于以经营某些专业险种为主的财险公司,主营业务险种对两者差异具有决定性影响。本文的研究结论详细解释了Solvency Ⅱ与C-ROSS在非寿险保险风险最低资本计算上的异同,对C-ROSS下一步的修订工作提供了一定的支持与参考。     

A REVIEW OF THE EMPIRICAL LITERATURE ON FARMER COOPERATIVES: PERFORMANCE,OWNERSHIP AND GOVERNANCE,FINANCE, AND MEMBER ATTITUDE

The empirical literature on farmer cooperatives is now fast emerging and developing in the areas of performance, ownership and governance, finance, and member attitude. We discuss 56 peer‐reviewed publications to illustrate the main findings and conclusions while outlining challenges and opportunities for future research. Generally, cooperative membership is found to positively impact price, yield, input adoption, income, and other indicators of member performance, yet there is growing evidence of an uneven distribution of benefits for small and large producers. In terms of structure, evidence of a causal relationship of ownership and governance to performance has been elusive, yet there are now many findings of inherent equity and long‐term debt constraints, often in the context of consolidation to drive scale and scope economies. Further inefficiency is observed to be driven by increased heterogeneity in member attitudes and objectives, in particular in terms of commitment and participation. Thus, overall, empirical work portrays farmer cooperatives as flawed and complex business organizations which nonetheless have a strong positive impact on its members. While applied research may progress in various directions, a general improvement in empirical methodologies is needed to allow robust analysis of mixed objectives in dynamic environments.

Do goodwill impairments affect audit opinions? Evidence from China

There has been a steady growth of goodwill impairments in the Chinese stock market since the adoption of the impairment approach in accounting. The influence of goodwill impairments on a firm’s financial position and profitability give reason to doubt its current and future performance. We examine whether auditors, as a crucial external monitor, identify the information risks of goodwill impairments and express their concerns about financial reporting quality in their audit opinions. Using a sample of firms listed on China’s A-share market from 2007 to 2017, we test the association between goodwill impairments and the type of audit opinion received in the same financial period. Our findings are as follows. First, the probability of receiving a modified opinion increases with the amount of goodwill impairments. Second, the positive association between goodwill impairments and modified audit opinions is driven primarily by earnings management risks. Third, this positive association is more salient when auditors are industry experts and there is no auditor–client mismatch. Fourth, auditors are more sensitive to the amount of goodwill impairments than to their mere existence. Overall, we document that auditors perceive goodwill impairments as a signal of information risks and communicate their concerns to investors to avoid litigation.     

农民金融素养、农地转入与农地抵押融资——基于陕西、宁夏、山东1947户农户调查数据的实证

探索性构建了要素流动视角下"金融素养—农地转入—农地抵押融资"的理论框架,阐释了农民金融素养、农地转入与农地抵押融资交易之间的关联机理,采用陕西、宁夏、山东农地经营权抵押贷款试点地区1947户农户调查数据,运用工具变量法实证探究了金融素养对农民农地转入和农地抵押融资交易的影响,并运用中介效应模型实证检验了农地转入在金融素养影响农民农地抵押融资交易关系中的中介作用.研究结果表明,金融素养对农民农地转入参与及其规模、农地抵押融资参与及其规模均发挥显著促进作用.研究还证实,农地转入规模显著促进农民农地抵押融资交易,且在金融素养影响农民农地抵押融资关系中具有部分中介作用.据此提出系统推进农民金融素养培育工程、协调深化农地经营权流转改革和抵押融资改革等政策建议.
